  1. Tech Inferno Fan July-2015>> Anybody interested in the 12.5" 2570P should also consider a 14" Dell E6430. The E6430 is the superior performance platform due to it's 900P LCD option, NVidia dGPU option, unlockable turbo bins (+400Mhz) on i7-37xxQM/i7-38xxQM CPUs and x2 2.0 eGPU capability. All with a minor size/weight penalty. See http://forum.techinferno.com/dell-la...tml#post118135 for details. Welcome to the 2570P Owner's Lounge! A place to liase with other owners and share useful tips/tricks/mods to get the most satisfying user experience from this exceptional ultraportable notebook. Release date: 22 June 2012, Model name: Inventec SIMBA, Nick name: EXtremeBook for i7-quad upgraded units A 2570P can be had for as little as US$250 on ebay-US , still with remaining 3yr global onsite warranty. A bargain when you consider it's upgraded desktop-replacement performance and durable MIL-spec build in a small 12.5" package. A features set unmatched by any other Ivy Bridge or Haswell notebook that remains undisclosed by all online reviews and even by HP. Grab one before word gets out . 2570P highlights being: socketted CPU allows a easy user upgrade up to a 45W i7-quad, doubling i5/i7 dual-core CPU performance. The result of doing so being the smallest, most powerful systems available that can function as a desktop replacement. Ultraportable competitors like a 12-14" Lenovo X230/X1C/T430s, Dell E6230/E6330, Toshiba R930/R940 or 13" Macbook Pro all have soldered dual-core i5/i7 CPUs making CPU upgrades unfeasible. Need to upsize to a larger 14" Lenovo T430/T440 or (preferrably) a Dell E6440 to get a socketted CPU. rare 5Gbps expresscard slot allows implementing a ~$160 GTX560Ti@x1.2Opt DIY eGPU for gaming graphics, CUDA/OpenCL processing or driving more external LCDs. optical drive can be swapped with a second 2.5" 9.5mm SATA-III 6Gbps SSD or HDD in a caddy & in a JBOD, RAID-0 (performance) or RAID-1 (redundancy) configuration. Can have up to 4TB of internal storage (2x2TB 9.5mm). Or RAID-0 2xSSDs for superfast boot-times and > 1GB/s sequential transfers. eSATAp port allows external bootable SSD/HDD to be attached using a single eSATAp cable. Ultra convenient when you consider USB-only systems like Macbooks require complicated software workarounds to get a Win7/8 disk booted off their USB ports. upgradeable wifi : can upgrade to recently-released 802.11AC standard with a Broadcom BCM4352 or Intel 7260 HMW card as explained. internal WWAN/3G capable : install a whitelisted WWAN/3G card, insert a mobile SIM and surf the internet anywhere battery options include a 31Wh 3-cell, 62Wh 6-cell (9hrs) and 100Wh 9-cell battery (15hrs) is listed by laptopmag as a top 5 HP laptop of 2013 (Dec-2013) and top 10 business notebook (Apr-2013) Comparison: http://forum.techinferno.com/what-no...html#post34610 concludes the 2570P is the best one.Comparison: 12.5" HP 820 G1 (Haswell: 4th-gen i-core) versus 2570P (Ivy Bridge: 3rd gen i-core) in spoiler: Comparison: 12.5" HP 2570P (Ivy Bridge: 3rd gen i-core) versus 2560P (Sandy Bridge: 2nd gen i-core) Example user-customized 2570P systems ordered by CPU performance User CPU clock TDP x27-TDP Storage: 9.5mm primary + ODD bay Other mods i7 quad-core equipped 2570Ps Aikimox i7-3840QM@2.93 45W 500GB + 1TB HDDs (1.5TB) OC ME FW, 16GB DDR3, cooling Tech Inferno Fan i7-3740QM@2.83 45W 22.1W 256GB S840P.SSD + ODD + 500GB eSATAp GTX770 eGPU, OC ME FW, BCM4352AC wifi, battery life tweaks, cooling Dewos i7-3840QM 2.8 45W 24.8W 128GB+128GB RAID0 SSDs GTX660 eGPU, 16GB DDR3 badbadbad i7-3840QM 2.8 45W 26.2W 500GB S840 EVO SSD + ODD 16GB DDR3L, BCM4352AC wifi invait53 i7-3840QM 2.8 45W 128GB SSD + 2TB ST HDD 16GB DDR3, WLAN-USB, BCM4352AC wifi+BT4.0 paperclip i7-3820QM 2.7 45W 22.4W 240GB Intel 530 SSD + ODD jacobsson i7-3740QM 2.7 45W 256GB+256GB RAID0 SSDs + 500GB eSATAp GTX670 eGPU, 16GB DDR3L, cooling pandaleo i7-3740QM 2.7 45W 24.5W 256GB Toshiba SSD 16GB DDR3L Uftherr i7-3720QM 2.6 45W GTX570 eGPU, 8GB DDR3, cooling hatoblue i7-3630QM 2.4 45W 23.6W GTX560Ti eGPU krazyazy i7-3632QM 2.2 35W 24.5W 256GB S840P.SSD + 500GB HDD GTX660Ti eGPU, 16GB DDR3L phillofoc i7-3632QM 2.2 35W 25.5W 128GB C400 SSD + 500GB HDD GTX650Ti eGPU, 16GB DDR3L, 7260AC wifi, battery life tweaks bjorm i7-3632QM 2.2 35W 25.7W 500GB S840 SSD + ODD GTX560TI eGPU, cooling+quiet_fan+holey_bottom i5 or i7 dual-core equipped 2570Ps rhx123 i7-3520M 2.9 35W 256GB LiteOn LCT-256M3S SSD + ODD GTX780 eGPU jot23 i5-3210M 2.5 35W 128GB C400 SSD + 640GB HDD GTX660 eGPU xuhexiffi806 i7-3689Y 1.5 13W 180GB Intel 530 SSD + weight saver 100Wh 9-cell battery, expresscard-SD reader PURPLE - highest performance AND lowest power consumption in this table RED - highest performance configuration in this table GREEN - lowest power consumption in this table x27-TDP: TDP when running at x27 reflecting overall CPU temps and efficiency as discussed Operating System, Support, Drivers, Disassembly Guide HP's 2570p Drivers Link, Manuals Link, Maintenance And Service Guide, Disassembly Guide, Media Services Link w/ videoWindows 7 OEM HP Source - For Clean Installs : includes additional HP installation contents needed for a Win7 clean install media.2560P schematic : 2570P is similiar but unfortunately no public schematic found for it as yet. This is the next best thing.HP warranty checker : useful to check a ebay secondhand unit's remaining warranty Performance upgrade: i7-quad CPU resulting in 'IVB ZBook 12' or 'EXtremeBook'Can effectively double the CPU performance going from a factory i5/i7 dual core to a i7-quad CPU. Could also be desirable if you wish to lower fan noise and temps. Running a i7-quad with max 99% CPU utilization results in noticably cooler temps than their dual-core counterparts without loss of performance, eg: cool i7-quads by bjorm's i7-3632QM or Aikimox's i7-3840QM. Note: warranty implications of a CPU upgrade - a factory-specced faster dual core up to i7-3520M 2.9 will not void warranty while a i7-quad will void the warranty if HP know about it as it wasn't offered with one. I'd keep the original CPU back and swap it back in if necessary. Upgraded 2570P i7-quad system examples are shown in the table above.NOTE: A 45W CPU can have highest multiplier limited to a 35W CPU level using Throttlestop software. That means a 45W i7-3630QM/i7-3610M (turbo=3.4/3.3Ghz) runs like a 35W i7-3632QM/i7-3612QM (turbo=3.2/3.1Ghz). Best 45W i7-quads being a i7-3630QM (x32) , i7-3720QM (x34) and i7-3740QM/3820QM (x35). There is at max 9% 4-core peformance difference between these with the higher end ones often not being able to maintain their upper multipliers as shown here. Meaning, suggest grab whichever is available and of lowest cost in your area.The 4-core TDP limit means any faster 45W CPUs do not see any gains. If need more performance and have deeper pockets then consider purchasing a 55W i7-3920XM instead. It has an additional 10W heatroom for turbo. Though it will absolutely need cooling mods to be able to accomodate at that level. <- 55W CPU is being limited to 45W on a 2570P as shown.It's possible to get and install cheaper PGA-to-BGA converted i7-quad CPUs as demonstrated by pandaleo.RECOMMENDED reading: How to choose the most efficient 45W i7-quadPerformance upgrade: external graphics (eGPU)DIY eGPU to attach a desktop videocard via the 2570P's 5Gbps expresscard slot.

Simply and the turn the system to standby system and attach the PE4L. Your system will return to its desktop presets once it detects the PE4L. You will immediately see a significant upgrade in the performance. For example. a Inspiron 1440 using the x1E tweak saw 3dmark06 go from 866 to 9551. RE5 benchmark went from an unplayable 4.1FPS to a very playabe 60.9FPS. The HP 2560P's x1.2Opt link saw 3dmark06 increase over 4 times to 18340 and RE5 gave an average of 148.3FPS(!!), even allowing the internal LCD to be driven by the eGPU.

    Pre-purchase FAQ

    .nobrtable br{display:none} .tablesmallfonts td{font-size:xx-small} PRE PURCHASE FAQ >>> Macbooks Owners - pls refer to https://www.techinferno.com/index.php?/forums/topic/7947-the-basic-egpu-hardware-guide-for-macs/ instead of this document. 1. How does a DIY eGPU differ from a Villagetronic ViDock? 2. How can I check if my notebook is compatible with an eGPU? 3. I don't have an ExpressCard slot. Can I still do use a eGPU? 4. Can I make this work using just my notebook's LCD display? 5. (Performance) What affects the performance of a eGPU? 6. (Performance) Can my system do a PE4H x2 or x4 link as shown in PCIe Scaling Analysis? 7. (Performance) What recommended candidate notebooks should I buy for best performance? 9. (Performance) How could manufacturers make eGPU x2 2.0 notebooks? 10. My system has switchable graphics. Can I still do install a DIY eGPU? 11. My Villagetronic ViDock product isn't working. Can you help? 12. Can I solder my own adapter to host an eGPU instead of buying one from BPlus, Redtrontech, Villagetronic? 13. What do I need to run the fastest x1.2Opt link shown in the implementations? 14. I have no expresscard slot. Can I use my wifi mPCIe slot to host the eGPU and still have internal wifi? FIRST STEPS >>> See Techradar's How to make an external laptop graphics adaptor article for an overview. 1. What parts do I need and where can I buy them? 2. Which video card do you recommend for best performance on my system? This will be determined by your chipset, if additional ports available for x2 linkage and whether you have Intel 4500MHD, HD, HD3000 or HD4000 graphics. The matrix below makes recommendations based on the system chipset with: -LIME recommend NVIDIA Fermi/Keplar (GT430 or better) solution for best performance -RED recommend AMD HD5750 or better solution for best performance -CYAN choose based on preferred performance bias: DX9 (AMD HD5750 or better) or DX10/DX11 (NVIDIA Fermi/Keplar). Though specifically for x1 1.0 I recommend a system upgrade to a better performing candidate as users find uneven & choppy performance. Thunderbolt users may still elect NVidia Optimus solution (if have an iGPU) as then can then render the image to the internal LCD. Refer to Performance: AMD versus NVIDIA benchmark results to help you decide. If not sure then suggest a NVIDIA Fermi/Keplar solution which on balance gives better overall performance and has the option of x1.Opt with the right notebook. Note: if the NVIDIA x1.Opt driver was unlocked to allow primary video cards other than Intel 4500MHD/HD/HD3000/HD4000 plus it engaged with x2 links then I would recommend only NVIDIA solutions.

Provides ability for the internal LCD to render games running on the external GPU. 3x1E tweak uses a x2 link on port1, 3 or 5 with a single lane for 15-30% more perf (AMD/non-Fermi|Keplar NVIDIA only). 4x2E tweak use two lanes of a x4 link, [port1+2] as EC+mPCIe or mPCIe+mPCIe for 30-60% more perf (AMD/non-Fermi|Keplar NVIDIA only). 5 x2=combining expresscard+mPCIe or mPCIe+mPCIe slots [p1+2], [p3+4], [p5+6] or [p7+8]; x4=[p1+2+3+4] or [p5+6+7+8]. 6Series-6/7: Only for Thunderbolt-equipped notebooks. Trying to combine mPCIe+expresscard slots no longer possible as Intel now locking the link width in the flash descriptor. Requires advanced bios hacking to configure x2 link, cannot be done using Setup 1.x. 7: would only be possible if the expresscard slot was wired to the northbridge which runs pci-e 3.0. All expresscard slots so far have been using the southbridge which is currently limited to pci-e 2.0. So we can say this is not possible. ? Don't know if non-Intel chipsets can do x2 links. 8: NVidia 306.97WHQL is the last to support Optimus x1-pcie compression and internal LCD mode on 4500MHD iGPUs. REF http://forum.techinferno.com/diy-e-gpu-projects/6253-t500-compat-q-4500mhd-optimus-ends-306-97whql-2.html#post89243 9: can enable phantom iGPU to gain x1.Opt performance on dual-core i3/i5/i7 Series-5 chipsets using Win8.x as demonstrated If going AMD, recommend a HD5xxx+ series card over a HD4xxx series due to their more efficient usage of PCIe bandwidth. Benchmarks would predict a HD5670 to outperform a HD4870. Avoid twin-gpu cards like a HD6970/GTX590 since they require 2x256MB PCIe space windows which might be difficult to accomodate. Examples based on power consumption requirements 12V/75W adapter: HD5670, unplugged HD5750, NVIDIA GT430. 12v/80w: specific HD5750 units.

It's situated above the WWAN marking as shown in the spoiler below. In fact, this slot is WLAN(PCIe1), mSATA (SATA3 port4) and WWAN (USB 2.0)!! Sharing the PCIe and SATA lines being a new Series-8 Flexible I/O chipset feature : http://forum.techinferno.com/diy-e-gpu-projects/6882-series-8-flexible-usb3-pcie-sata-pcie-i-o-some-more-x2-2-0-possibility.html#post94382 Performance upgrade: i7-quad CPUCan effectively double the CPU performance going from a factory i5/i7 dual core to a i7-quad CPU. Note: warranty implications of a CPU upgrade - a factory-specced faster dual core up to i7-4610M will not void warranty while a i7-quad will void the warranty if Dell know about it as it wasn't offered with one. I'd keep the original CPU back and swap it back in if necessary. Upgraded E6440 i7-quad system examples are shown in the table above.One important consideration is whether to get a 37W i7-4702MQ (4-core turbo=2.9Ghz)to keep within the factory-configured CPU's TDP or get a faster and hotter 47W i7-4800QM/i7-4700MQ (4-core turbo=3.5/3.2Ghz). I'm of the opinion that the 37W one should be avoided. That's because (1) the 47W CPUs can be software limited to 37W (2) XTU/Throttlestop allows a negative offset voltage offset to be applied bringing TDP down and allowing higher multipliers to work and (3) the beefier dGPU-model heatsink that can handle the higher TDP and can be retrofitted to the iGPU-only model.The E6440 BIOS locks the TDP but allows extra turbo bins are accessible using either Throttlestop or XTU. Eg: a i7-4700MQ has +200Mhz unlocked turbo bins (max=3.4Ghz 4-core). A i7-4800MQ has +400Mhz unlocked turbo bins (max=3.9Gbz 4-core). Problem with the 47W TDP limit is it limits performance to 3.5Ghz during a TS 32M/1024M 4-core load test. That result being *after* voltage optimization in XTU/Throttlestop. Meaning then that max performance lies between a turbo unlocked i7-4700MQ (3.4Ghz) and i7-4800MQ (3.9Ghz). Eg: a i7-4710MQ (3.5Ghz 4-core) would be at max TDP limits. Though those newer CPUs are rarer and often pricer than a faster i7-4800MQ. Means then that for the majority of users, a i7-4800MQ gives an easy plug'n'play installation from which highest performance, within TDP and thermal limits, can then be extracted easily using Throttlestop or XTU.RECOMMENDED reading: 1. http://forum.techinferno.com/throttlestop-realtemp-discussion/6958-haswell-step-backwards-ivy-bridge-i-have-some-shocking-tdp-results.html#post951812. INFO: dGPU_heatsink - improve iGPU model cooling by retrofitting dGPU model heatsink+fanPerformance upgrade: external graphics (eGPU)RECOMMENDED reading: INFO: EC_retrofit - retrofitting an expresscard slot to a E6440An eGPU has been implemented on a E6440 using a NVidia GTX770 (Tech Inferno Fan), AMD R9 280X (Tech Inferno Fan).DIY eGPU: attach a desktop videocard via the E6440's 5Gbps expresscard slot. Provides accelerated gaming graphics, CUDA/OpenCL processing and additional HDMI/DVI outputs to drive multiple monitors. A NVidia or AMD card is a straight plug-n-play implementation on a E6440. The system must boot least once with the eGPU attached and detected by the BIOS. This lowers TOLUD from 3.49GB to 3.24GB, storing it in NVRAM thereafter. Both my GTX770 and R9 280x can then be allocated without any error 12. In addition, no PCI Reset Delay mechanism is unnecessary and is best to be disabled. Then the system and eGPU can support a sleep-resume cycle with eGPU activate on resume. NOTE: The A.02 BIOS handles the eGPU beautifully, running a Gen2 expresscard link. Unfortunately bios A.05 or newer sets the EC port to Gen1 speed if you hotplug the eGPU after BIOS boot (see details). Flash back to A.02 to get the faster Gen2 link speed OR disable any PCI Reset Delay mechanisms on the eGPU adapter so the BIOS sees the eGPU on boot. Note: E6440 iGPU-model can boot with powered eGPU powered plugged into EC slot. dGPU-model E6440 will not boot with powered eGPU plugged into EC slot and so requires hotplugging after boot. In case anybody is wondering, a x2 2.0 eGPU link is not electrically possible unless there is a USB3 port 4 on a docking connector so can use the http://forum.techinferno.com/diy-e-gpu-projects/6882-series-8-flexible-usb3-pcie-sata-pcie-i-o-some-more-x2-2-0-possibility.html#post94382 feature.

The E6440 PCIe port layout is shown in the spoiler: If want to experiment with a x2 2.0 eGPU implementation then suggest look at a one-gen older Dell E6430.

Required is swapping the HD 1ch LVDS cable for the 2ch LVDS HD+ and of course changing the 768P LCD for a 900P one. The two different LVDS cables available for a E6440 are: The two different LCDs being: My system came from the factory with a 900P AUO B140RTN02.2 panel with Dell p/n 0M4RTT. I find brightness and viewing angles quite satisfactory. A photo of my 900P LCD's model labelling is in the spoiler below. 1080P or higher resolution : not possible since the E6440 uses a LVDS rather than eDP internal LCD interface. The max resolution available in 14" LVDS is usually 1600x900, representing 37% more viewing area than 1366x768. Though ebay has 14" 1680x945 LVDS LCDs, giving an additional 10% more viewing area over 1600x900 or 51% over 1366x768. --> 1680x945 LCD does not fit correctly as attempted here.System mods: coolingINFO: dGPU_heatsink - improve iGPU model cooling by retrofitting dGPU model heatsink+fan.

  7. no more 4GB+ system RAM issues: use a DSDT override to extend the root bridge into 36-bit space (Windows 7/8/10 only - MacOS/Linux are unaffected) Introduction>>> This problem and solution is only relevant to Windows operating systems. MacOS ignores the root bridge and can allocate in 64-bit space as kizwan found here. Linux has a "noCRS" kernel parameter to ignore the root bridge boundaries so the OS can also also allocate in full 64-bit pci-e space. The this process aims to solve the problem of seeing an error 12 (This device cannot find enough free resources that it can use) issues against a eGPU in Windows Device Manager due to insufficient 32-bit addressing space. By manually adding a memory range outside of this 32-bit space, we can force Windows to operate in 36-bit space instead to host eGPUs. Know systems that will require this process are Dell Latitude Ex410 series, Samsung Series-4, Sony F-Series and MSI CRx20, HP-Elitebook/Probook xx60x/xx70x with AMD GPUs. Those have insufficient free 32-bit PCI space to accomodate a eGPU if have 4GB or more of RAM installed. They can't use Setup 1.30's PCI compaction to create sufficient space because they either have TOLUD=3.5GB, have lower TOLUD like 3.25GB but with an unmovable systemboard device occupying candidate free pci space making it unusable or are using an AMD or GTX650/GTX750 card that requires over 256MB contiguous space. Refer to Pre-Purchase FAQ #2(>> 2. How can I check if my notebook is compatible with an eGPU?) for details on how to check your TOLUD. The same solution can be applied to any 3-gens old PM965 chipsets (2007) or newer system. They have a 64-bit CPU and chipset so are fully PAE-36-bit/64-bit compatible. Dell Inspiron 1440/1525 (core2duo) and Dell Vostro 1015 (core2duo) have BIOS-configured 36-bit root bridges already so don't require this workaround. I happened to run into one of these problematic systems. A Dell E4310 with TOLUD=3.5G which can be maxxed out at 16GB of RAM. It's too nice an ultraportable to be need to downgrade RAM to 3GB of RAM to use an eGPU. I set of in pursuit of how to add a DIY eGPU to it which is documented below. Using Setup 1.30's 36-bit PCI compaction on the eGPU to relocate it in such space will see the eGPU still give an error 12 in Device Manager. Why is that? Avlan confirmed that the 32-bit root bridge definition limited allocation only to 32-bit space. The fix being a modified DSDT loaded as a registry override that extends the root bridge (ACPI PNP0A08 or PNP0A03 device) into 36-bit space. Avlan's fix was cryptic so wasn't attempted on other systems. After a bit of digging from the following references I found the QWORDMemory DSDT static resource entry can be used to easily extend root bridge entry into 36-bit space. Ref: [Qemu-devel] [PATCH 6/6] 64bit PCI range in _CRS table plus two examples at virtualbox and Coreboot. Tools required>>> The iasl and asl tools used are in 2570P-dsdt-override or (older) DELL-36b-root-bridge.rar.

See also http://forum.techinferno.com/diy-e-g...html#post49833 , user angerthosenear's alternative instructions to those presented below where can use a DSDT Editor to simply the patching process if experience a compilation error: NOTE: kizwan expands steps 1-3 here. Useful if you need more assistance with these steps. Kizwan also provides a video tutorial . 1. Identify the resources used by the PNP0A08 or PNP0A03 devices in Windows. This can be found by perusing Device Manager->Resources by connection->Memory. Then check the last PCI BUS entry. Eg: 2. Capture the DSDT table using command below. This gives a raw dump of the ACPI tables in .dat files. dsdt.dat is the one we will be using. Newer versions of iasl no longer having the "-g" option in which case use acpidump instead. iasl -g acpidump -b 3.Decompile dsdt.dat to get an output dsdt.dsl text file that can be editted: iasl dsdt.dat 4. Open the resultant dsdt.dsl file and look for the PNP0A08/PNP0A03 'DWordMemory' resource entries. Under the last DWordMemory entry in that area, add a 'QWordMemory' (64-bit) entry shown as the second paragraph below. I ensure that I stay in the 36-bit range (< 64GB) so the location is compatible with the PAE-capable Win7 32-bit. I also chose a location above 48GB so we won't have issues with maxxed out memory. The range chosen was 48.5GB to 56.25GB. DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite, 0x00000000, // Granularity 0x000A0000, // Range Minimum 0x000BFFFF, // Range Maximum 0x00000000, // Translation Offset 0x00020000, // Length ,, , AddressRangeMemory, TypeStatic) QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite, 0x0000000000000000, // Granularity 0x0000000C20000000, // Range Minimum, set it to 48.5GB 0x0000000E0FFFFFFF, // Range Maximum, set it to 56.25GB 0x0000000000000000, // Translation Offset 0x00000001F0000000, // Length calculated by Range Max - Range Min. ,, , AddressRangeMemory, TypeStatic) 5. Create a dsdt.aml file with the 'iasl -oa dsdt.dsl' compiler directive. '-oa' disables all optimizations found necessary to get working solutions. It is unlikely this will succeed first time, as the compiler is very strict. In general warnings are acceptable, but errors may require some fiddling. Those will need to be corrected with common patches in Common DSDT patches for Ivy/Sandy/Haswell laptops, How to fixed DSDT errors? (kizwan). Consider asking for guidance at tonymacx86.com DSDT forums. DSDT editting alone could have it's own forum. Then try compiling your DSDT again. iasl -oa dsdt.dsl 6. Load the dsdt.aml file into into the registry as a DSDT override. You must be an admin user for this to be successful. asl /loadtable dsdt.aml 7. [Windows 8.x/10] Enable test signing mode for the registry override to apply. You must be an admin user for this to be successful. bcdedit -set TESTSIGNING ON An alternative to disabling testsigning in Win8/10 is to do a Win8: Perform a DSDT substitution within Setup 1.30 to overcome TOLUD issues. Win7 users who don't want to do the registry override can also do this DSDT substitution. 8. Check you now have a new Large Memory entry in Device Manager->Resources by Connection->Memory as shown below: 9. The same fix was done on a Dell E4300 and Win7 did automatically allocate the eGPU into the 36-bit space. If you still see error 12 then there are two options to pursue: Re plug'n'play the devices. Go into Device Manager -> Video cards, delete the eGPU. Also go into Device Manager -> System devices and delete the PCI Express Root Port x entries. Upon restarting the system, halt Win7 startup with F8, attach and power on your eGPU and then proceed to load Win7. Win7 should now be clever enough to re-allocate the eGPU into 36-bit space upon realizing there is insufficient 32-bit space to host it. Can go one step further and delete your eGPU NVidia/ATiAMD driver, restart the system and reload it. That may help as well. Hard allocate the eGPU into 36-bit PCI space before booting Win7 using Setup 1.30. Select PCI compaction->Endpoint=56.25GB (36-bit) and then select Run compact. When prompted for the scope select eGPU. The result will be similar to that shown in the spoiler in step 8 above, but with the eGPU rather then the Intel HD iGPU being in 36-bit PCI space. Can then proceed to automate this by editting your %DRV%:\config\startup.bat (or V:\config\startup.bat in windows) so can just select the Automated startup via startup.bat Setup 1.30 bootitem and have it do everything for you: call speedup lbacache call vidwait 300 call vidinit -d %eGPU% call pci call chainload mbr Testing results>>> * Lenovo X230 (jay_dark_dry): SUCCESS!

    mPCIe/EC eGPU troubleshooting steps

    We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt. Here's some common problems and some troubleshooting steps to correct them. Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected? I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver. mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place Use the Setup1.30 PCIe Ports->enable to enable the missing port. eGPU does not get detected Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work. 1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected? 2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected? If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system from say http://www.bios-mods.com OR test the Setup 1.30's PCI ports->undo_whitesting feature. eGPU still not detected - set the PSU to be permanently on The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted. Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that: http://forum.techinferno.com/enclosures-adapters/8441-%5Bguide%5D-switching-atx-psu-using-paperclip-trick-swex.html http://forum.techinferno.com/enclosures-adapters/9426-220w-dell-da-2-ac-adapter-discussion.html eGPU still not detected - a non-standard mPCIe implementation by your vendor? PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689 eGPU still not detected - faulty hardware? If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty. NVidia driver stops responding EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors. The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30 Other troubleshooting help resources?

  10. DISCLAIMER: use these modified bios at your own risk!!You will be responsible for any damage to your computer system or loss of data that results from using a system with a modified BIOS. Ensure your system's cooling system is working well before trying any overclocking. These BIOS are not tested or approved by HP. Alert - do NOT upgrade if you are using a F.20 or newer bios. Doing so will endanger your ability to flash the modded bios below providing no-whitelist, dual-IDA and SLIC 2.1 functionality. Details here.IntroductionI noticed that mostly Dell and Alienware Core 2 Duo systems were dual-IDA capable from the factory. I proceeded to successfully modify and test the 2510P dual-IDA bios, extending the modification to other Santa Rosa HP and Montevina HP Business notebooks. Find the resultant modified bios-es below: Flashing a dual/quad-IDA bios will provide an extra multipler, gaining 5-17% more CPU performance on an IDA-capable CPU when using Throttlestop. Examples shown on the right. Throttlestop also provides IDA overvolting and superLFM undervolting to provide greater setfsb overclockability on AC and increased battery life on DC. Combining dual-IDA/quad-IDA and PLL overclocking will give the greatest possible overclocking. Installation Instructions Windows users Download package of interest in the Version column on the right, double-click, extract to a desktop folder then run the HPQFlash file and follow instructions. The supplied HPQFlash is modified by TTAV134@mydigitallife to allow successful flashing of a modified bios. If HPQFlash doesn't do anything and you see a LOG file containing an entry WMI BIOS Flash function is not supported on this system, then install HP Quick Launch Buttons on your system and try again OR perform a DOS based install like for Linux users below. Linux users (Santa Rosa) Download and install modified rompaq from here. Download bios file of interest from above, extract rom.bin from the ROM.cab and copy it as 68***.bin on your DOS bootable USB thumbdrive. Reboot using the USB drive and install bios using the rompaq utility. How to setup Throttlestop to use the extra multiplier the dual-IDA/quad-IDA bios provides? See 2.0's great guide here starting at step 3. .

  11. <i>This issue has been logged with the text below on the HP Support Forums at http://h30434.www3.hp.com/t5/Notebook-Hardware/HP-ZBook-15-17-G2-has-non-functional-expresscard-slot/td-p/4962544</i> The ZBOOK 15/17 G2 series looked to be the perfect candidate for me to do EC and TB2 testing with. Unfortunately it looks like the G2 series has a non-functional expresscard slot. Both my own testing with a 17G2 and that of @hishamkali with a 15 G2 here <i> where he says "I have noticed that the express card slot on my unit seems to not work</i> confirming this to be the case. My analysis below points to the introduction of the Z Turbo Drive (x2 2.0 PCIe SSD) in the G1->G2 revision as being the cause of the lost expresscard slot functionality. The ZBook 15 G1 has a working expresscard slot as can be seen at http://www.tinhte.vn/threads/hoi-egpu-external-desktop-gpu-for-laptops-mo-rong-card-do-hoa-gan-ngoai-cho-laptop.2350894/#post-43575840 . Wonder how HP will fix this since they are advertising the G2 systems with an expresscard slot? Will they install revised boards for affected users? Otherwise they could transplate a TB2 chip onto the TB1 systemboard. Though the use of a G1 systemboard means no Z Turbo drive functionalilty. Or else affected users could seek a refund and acquire a 15" Lenovo W541 instead which does have a EC2 slot and a TB2 port. Analysis details below: ZBook 17 G2 QM87 Southbridge port layout (max = 8 ports) ZBook 15 G1 QM87 Southbridge port layout (max = 8 ports) How HP could make a revised ZBook G2 systemboard to provide a functional expresscard slot

I'm wondering if the ebay items are as low profile as they can go while providing a 90 degree bend AND do it safely.
  13. [Started 2-13-2009 as *HP 2510p Owners Lounge* (NBR). Relocated to T|I due to being banned by Lenovo fan ZaZ] Welcome to the 2510P Owner's Lounge! A place to liase with other owners and share useful tips/tricks/mods to get the most satisfying user experience. A running summary is below: Release Date: 27 June 2007 (pre-GFC build quality) Alert about HP's 2510P bios F.20 or newer - do NOT upgrade to it for these reasons unless you don't care for the awesome no-whitelist, dual-IDA, SLIC 2.1 modded functionality. Also expect your resale to be worse if it's got the > F.20 bios once buyers figure out they are the undesirable systems to have.Alert about HP's newer and faster replacement ZIF HDDsIf your factory-delivered slow 60GB/80GB/120GB 2-platter Toshiba ZIF HDD has bad sectors then HP replace it under warranty with a higher-density thinner (5mm versus 8mm) single-platter drive. Eg: HP replaced my 80GB MK8009GAL with a MK8025GAL. It's still 4200rpm but my Win7 WEI disk increase from 3.9 to 4.4. It's faster and consumes slightly less power. The reason for this 'upgrade?'

Block diagram in the spoiler: Mini 2510P ReviewThe 12.1" HP 2510p ultraportable has an impressive 5-6 hour battery life from the 10W TDP ULV U7x00 CPU and 6-cell battery. It is rather inexpensive too which I assume is because it is now older tech and the reviews highlight the bottleneck 23MB/s 4200 RPM 1.8" PATA drive, dreadfully slow against 50-60MB/s 2.5" drives. The 2510p is a far better user experience than cost competitors such as a netbook and pricier newer CULV systems (see comparative SU7300/SU9400 overclocked performance). It comes with 3yr global onsite warranty, a decent-sized keyboard with touchpad and touchstyk, 1280x800 LED backlit matte LCD, pcmcia slot, mini firewire port, DVD writer, internal modem, bluetooth, WWAN-ready with mPCIe slot+antenna+SIM slot, 2xUSB ports with the left one being powered. Weighs 1.46kg with the 6-cell battery, without the 180gram DVD and has optional accessories available: docking station with s-video port, 9-cell battery.

  14. Bizon (RU) has struck again, this time modding an AKiTiO Thunder2 and calling the end result a "BizonBox 2" As seen on the Google-translated BizonBox 2 product page (RU). Bizon = serial overpricer?! Like his overpriced previous expresscard offering, he wants a staggering USD$533 (!!) (29890 Russian Rubles) for his box supplied with a 220W Dell DA-2 PSU and no Thunderbolt cable. His value add over a standard http://forum.techinferno.com/enclosures-adapters/7205-us%24189-akitio-thunder2-pcie-box-16gbps-tb2.html#post98210 being ventilation holes on the outer cover, a Dell DA-2 PSU + input jack placed at the front, a cutout for the PCIe connectors on top and a (imho) silly looking Bizon logo. Obviously attempting to generate a tidy profit for his efforts based on some of the older examples presented here. At no time does he disclose what that it's a AKiTiO Thunder2 enclosure instead calling his modified form a "unique solution" emblazed with his name. What's the bet he'll introduce low-profile PCIe connectors in his next revision and get rid of that unnecessary cutout on the top cover? Thumbs-down - warning potential customers of being ripped off You can thumbs down his video to alert potential customers there is something amiss with his product and/or post on his youtube page. I've posted a warning but again he's censoring it.

    1. The STATUS window will list say "p1@x1.1 10de:0a6f@x1.1 (NVidia)" to indicate detecting your eGPU on a mPCIe/EC port. The boldfaced letter indicates if the port is running at Gen1, Gen2 (2nd gen i-core+) or even Gen3 speed (6th gen i-core+) 2.

If you have only a dGPU that's wired to run your internal LCD, then yes, trying to disable it will cause a hang. The dGPU can be disabled if it's secondary in a switchable graphics environment with the iGPU as the primary. 4. Set Chainloader->mode=MBR, then chainloader->Test Run. 5.

    The window drag method works with NVIDIA or AMD. @LukeHero has a method where an external lcd isn't needed. Instead, he creates a pseudo external lcd with a hdmi-vga adapter, windowed app started on pseudo monitor driven by the egpu and management software used to move it to the internal lcd. https://www.techinferno.com/index.php?/forums/topic/8088-2012-15-mbpr-gt650m-gtx97010gbps-tb1-akitio-thunder2-win10-lukehero/ It's something to keep in mind if can't get NVIDIA Optimus working.
