Ask vendor for the Support Tag.Performance upgrade: mSATA SSDYes, there is a mSATA slot in the E6440, though is not visible when taking the rear cover off. It needs the left bumper cap removed. 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 USB 3 ports on the system are 1, 2, 3 and 6. 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. It's has two mPCIe ports (port 1 + 2) as per the E6430 schematic. System mod: LCD upgradeUpdate Feb-2015: newer E6440 has eDP rather than LVDS connected on the systemboard, with a 1920x1080 LCD option. See details. The FHD LCD retrofit parts required for the 1st E6440 series are in the spoiler: NOTE: The Intel iGPU Control panel mistakenly lists the LCD as being eDP as explained in the series-1 E6440.768P->900P is possible as a user upgrade. 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.

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 [email protected] 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.

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.
