In our 680M SLI vs AMD 7970M Crossfire article, we cited a multitude of reasons that we felt gave nVidia the edge over AMD despite the price disparity. Specifically with respect to multiGPU setups, we noted that the 7970M Xfire just didn't seem as smooth as 680M SLI (despite achieving performance parity) and there was more noticeable microstuttering which adversely affected gameplay and perceived smoothness. From our article: Well now HardOCP just published a 7970 vs 680 multidisplay comparison and they had this to say in their conclusion: BTW friendly tip for Radeon 7970M Crossfire users: Download Radeon Pro, it has a feature to help smooth out the microstuttering for AMD cards and it works quite well. It's pretty sad that a third party developer is able to fix what AMD still cannot accomplish through drivers. http://www.radeonpro.info/Download/R...ro_Preview.exe Release notes: - New: Dynamic Vsync Control (DVC) support. This feature controls how vertical synchronization is applied at rendering time, automatically turning it off when frame rate is below monitor's refresh rate to reduce stuttering and turning it on when framerate is above or equal to monitor's refresh rate, improving smoothness. - New: Dynamic Framerate Control (DFC) support. This feature acts like a frame rate limiter with smoothness control, just set a frame rate target and RadeonPro will try to keep it as close as possible while maintaining frame rendering times close to each other to avoid stuttering.

You could also try switching the gmux before booting windows, for example in startup.nsh or using GRUB. But yeah maybe for the beginning it's easiest to just do it in windows because it's more interactive than rebooting all the time to see if anything happens. In the long run it might be necessary to do the switching before booting, so Windows sees the internal display connected to the intel card during boot. The following should switch the gmux to integrated (based on what the linux driver does): // new version of outb(2, 0x728) - switch ddc outb(2, 0x7c2) // write the value to the value register sleep 100ms // instead of gmux_index_wait_ready, just to be on the safe side outb(0x28, 0x7d4) // write the port to GMUX_PORT_WRITE sleep 100ms // instead of gmux_index_wait_complete // new version of outb(3, 0x710) - switch internal display outb(3, 0x7c2) // write the value to the value register sleep 100ms // instead of gmux_index_wait_ready, just to be on the safe side outb(0x10, 0x7d4) // write the port to GMUX_PORT_WRITE sleep 100ms // instead of gmux_index_wait_complete // new version of outb(3, 0x740) - switch external display outb(3, 0x7c2) // write the value to the value register sleep 100ms // instead of gmux_index_wait_ready, just to be on the safe side outb(0x40, 0x7d4) // write the port to GMUX_PORT_WRITE sleep 100ms // instead of gmux_index_wait_complete

I wrote a good part of the apple_gmux driver . The driver you linked previously is my old version that doesn't support the newest apple hardware. I don't remember if it's just the retina mbps, but apple changed how you have to communicate with the gmux chip. That's why poking at the old IOports doesn't do anything. See LXR linux/drivers/platform/x86/apple-gmux.c and [PATCH] apple-gmux: Add support for message box interface (as found in MBP10,1/Retina MacBook Pro) -- Linux x86 Platform Driver Development for more. Unfortunately I don't have access to a retina mbp so I can't help with testing/developing directly. When using any code from this, use the first link (or a recent mainline kernel), not the patch. Edit: So what you need to do to hopefully get a minimal version to work is to take the part so that runs. For that you need gmux_index_write8 (that's the same as the outbs, but with the message box interface), which requires gmux_index_wait_ready and gmux_index_wait_complete. I'm not sure about this, but maybe you can even skip the wait functions and for a rough first version just replace them with a long enough sleep.

Here are the results using the system in my specs. I have listed the names according to the vBIOS number (one being called 29, other being called 67). I have to say, the 67 has won against all others at stock voltage and is very stable (even if NVI and GPUZ doesnt work on it). Here's the images and results. Do take note that the 29 vBIOS was not stable at 980/2300. Decreasing the clock to 960 worked, but it maxed out at 954mhz. It still ran well. NVIDIA GeForce GTX 680M video card benchmark result - Intel® Core i7-3840QM CPU @ 2.80GHz,CLEVO P15xEMx score: P7731 3DMarks - the 29's results. NVIDIA GeForce GTX 680M video card benchmark result - Intel® Core i7-3840QM CPU @ 2.80GHz,CLEVO P15xEMx score: P7877 3DMarks - the 67's results. EDIT: I'll keep the 67 vBIOS as my new main until the next big one comes out. Good work svl7. Donations to you and get yourself a nice big drink. (Or just go happy hour) EDIT2: For anyone confused at what I mean by unstable: the programs would crash to desktop due to the card's drivers not working properly.

The winner of the contest is obligated to post a NSFW hot chick pic in the hot chick thread. So you don't win a prize, you give one to everyone else that lost.

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.

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.

Instructions for flashing the VBIOS of a NVIDIA video card: You'll need: A VBIOS file you want to flash The latest version of NVflash, a DOS utility to flash the VBIOS of Nvidia cards. A USB drive, formatted to boot DOS, in order to use NVflash How to create a bootable USB flash drive: The flashing procedure: Put the NVflash files to the root of your prepared (DOS bootable) USB drive. Do the same with the Vbios you want to flash. NOTE: DOS has a limit of 8 characters per file name (not counting the extension). So make sure to rename your files appropriately before putting them on the USB drive. Make sure the USB drive is plugged into a port which is active at boot, reboot the system and go to the boot manager. Choose to boot from your prepared USB drive. As soon as you see the command line you're ready to go, write dir and hit enter to display all the files on the USB drive. Display all Nvidia adapters in the system: nvflash -a or alternatively the longer version of the command: nvflash --list This command will return you a list with all Nvidia adapters present in your system. Here's an example output of this command run on my M15x with a 680m in it: NVIDIA Firmware Update Utility (Version 5.117) NVIDIA display adapters present in system: <0> N13E-GTX (10DE,11A0,1028,02A2) H:--:NRM B:02,PCI,D:00,F:00 The number in the <> brackets is the index of the corresponding device. SLI users will have more than one entry and flash each card separately. Backup your current VBIOS: Never forget to keep a backup of your original VBIOS before you flash anything non-stock. Use this command to save a copy of the firmware to your USB drive: nvflash -b filename.rom or with nvflash --save filename.rom Flash the VBIOS to your card(s): For a single card it's really straight forward, you don't need to worry about the adapter indices. Just use this command: nvflash -6 vbiosname.rom -6 will allow you to override mismatches of the PCI subsystem ID. In case of a mismatch you'll need to confirm the flash with 'y'. NOTE: Users with a non-US keyboard might need to press 'z' or similar, because the 'y' isn't at the same location for all keyboard layouts. SLI users will need to flash each card separately. The concept stays the same, but you will need to use the corresponding adapter index to flash a card. How to figure out the adapter nr. is described above. Flashing goes like this: nvflash -i[index] -6 vbios.rom [index] represents a number, namely the index you found with the 'nvflash -a' command. So a command example to flash a card which has index 0 is: 'nvflash -i0 -6 vbios.rom' When the flashing starts, just wait until it says that it's done. Then reboot with Ctrl+Alt+Del and remove your USB drive. Pro tip: Let me know if I missed anything important or if you have questions.

@Tech Inferno Fan: Nice to find your NEW 2.0 version of this great thread. I am new to techinferno.com and you are the reason for joining. - For the moment I have no questions, but I just want to say: If I search at "the other forum", I always find a lot references to your invaluable work and many helpful, experienced commentaries. Thank you so much! - Then I see your user name marked in red. - It's a shame and embarrassing. I hope all users will find you at this forum. It is YOUR work and YOUR Intellectual Property*, no "forum rules" and personal friction can change that! (* e.g. What is Intellectual Property? ) - Nando 4 Eva! - That's my opinion, I am no lawyer. BTW: Good luck for your thunderbold experiments! My eGPU experiences are: I use an Acer 5920G with a PE4H connected to a GTX560 and 2x link (1x express card slot, 1x miniPCI slot) as described at your thread. Just to mention for other users: I had some problems with a damaged HDMI cable, but now: Everything works fine! I could also establish a working single link using a SAMSUNG R60 notebook with the eGPU. EDIT: Added a picture of the SAMSUNG R60 with a connected PE4H (single link via expresscard slot, external VGA output):

Just one remark, the DELL 680M start to throttle from 76° with latest version of vbios. So the cooling support for notebook is necessary for my 17R3

I believe the reviewer compared it to a T430 because a 2570P weighs in close to a T430. It's heavier weight and HP's whitelisting of WWAN/wifi ports are the other disadvantages of a 2570P. Though I believe Lenovo whitelist their wifi/WWAN ports but unlike a 2570P, a hacked bios is usually available as a workaround. You are on the mark with advantages of a 2570P plus do note that a 2570P can accomodate a 2.5" 9.5mm primary drive + either a optical drive or a second 2.5" 9.5mm primary drive via a caddy. A X230 uses a 7mm 2.5" drive + second mSATA drive. So a X230 has lower storage capacity with it's 7mm/mSATA drives which also happen to be higher cost per GB than their 9.5mm cousins. A 2570P's upgradable CPU means if one puts a 45W i7-quad into it they'd get the smallest, most powerful system available in the current gen. Supports SATA-III RAID-0 across it's two drives (2.5" + 2.5" via optical caddy) too giving a very fast storage subsystem to match. Gadgetsnute, a NBR Dell E6220 user dismissed a X220 because of it's looks but wanted the IPS LCD. He ended up retrofitting a IPS LCD into his E6220. REF: Latitude E6220 IPS screen replacement . I wonder if the same can be done with a 2570P/2560P? If HP offered IPS on their 2570P then it would be a no brainer for me - a X230 with it's dated looks and less durable build wouldn't even be on the radar. In any case, a 2570P is a good one to keep on the radar once it trickles into the s/h market for it's upgradable CPU feature and business grade durability. Best if it still has some remainder of the higher-specced 3yr NBD onsite global warranty.

Thank you,This unlocked bios solved my problem IGP+HD 7970M.I can use only HD 7970M

I prefer Nvidia Inspector over MSI AB anytime... There are tons of changes in the vbios, whether you will notice a lot of difference when it comes to the performance... don't know. The modifications I've done are pretty much the same as in the previous version. Still stock clocks, but unlocked limits and performance tweaking.

970/1400 3d clocks. Let me know how it performs. Inspirion 7720 - A11 [650m mod 01 - 970-1400].zip

@Brian Wow! Getting a Bit better now. Keep going Brian ??? Maybe more memory clock ? http://www.3dmark.com/3dm11/5121938

No, if i remember correctly, the three jumper pins for the fan cable connection to the mobo normally represent: Voltage-in, modulated through PWM, so it spins the fan by giving it more or less voltage, at higher or lower pulse frequency. Then you have Mass, and then you have some kind of line out to the mobo (not sure if it's actually voltage out with the mass being there to prevent shorts, or if it's some kind of sensor). Either way, the custom controller doesn't care about feedback. It takes the temp readings from the sensors, it takes voltage from the 5V line solder, and then it sends voltage at a predefined pulse frequency to determine fan speed. When median between the two sensors reaches around 70 degrees, it kicks in full speed. Since both components tend to run very hot, that happens pretty fast, although i have to admit i would have preffered if it decided its speed based on maximum temp recorded from either sensor instead of a median. Still, it works well. I don't think your switch solution is clumsy at all. I would suggest using a simple circuit breaker button, one taking the voltage from the mobo by way of the default fan jumper, and one taking voltage from whatever 5V line you want, and when you press the button, you would switch between them. This would give you the benefit of having some form of variable speed on the fan and also not having it turn off completely if you're not running it full speed. At least the way I see it. I'm actually not educated in electronic tinkering

**** Modified the very latest Clevo 680m vbios and added it to the second post. It's a completely revised vbios, and for me it's the best performing so far. Might not be true for dual card systems. Let me know how it works for you. A very big thanks to Mythlogic for providing me with the vbios!! Should work perfectly fine in their latest Clevo machines, but I don't know about the HM series... Furthermore I added a tweaked version of the older Clevo vbios, so that users with systems based on the Clevo P1x0HM series can have some more performance as well. *** I'll send you a PM. Nope, won't work. And I should still post the GE60 bios... lol. Guess I could mod the GE70 as well when I find time. @johnksss just posted some fantastic 3dM11 scores. Yes, there is. Just added. Second post.

For P1xxHM based systems I recommend only using version 80.04.29.00.01 !! Some users reported issue with other vbios versions (stock or modified, doesn't matter). EM users make sure you're on the latest BIOS / EC same with increased 3d voltage ('OV') -> refer to the file name (Same warning as above applies to P1xxHM users). ----------------------- K3000m: (Nvidia) K3000m - 80.04.3A.00.07 'OCedition' -> higher software overclocking limit Should work on all K3000m, unless you got a board ID mismatch. (HP) K3000m - 80.04.33.00.2E - 'OC edition' - > same as above, but probably the better choice if you use a HP machine ----------------------- K5000m: (Dell) K5000m - 80.04.33.00.35 - 'OCedition' -> higher software overclocking limit, stock 3d clocks 758MHz It's Dell but should work on all K5000m, unless you get a board ID mismatch. ----------------------- GTX 670mx: MSI 670mx (1.5GB) - 80.04.5B.00.A5_'OCedition'_rev00 -> higher software overclocking limits, tweaked performance at high clocks. Same board as the Clevo card. Clevo 670mx (3GB) - 80.04.58.00.03_'OC edition'_rev02 -> same as above, plus voltage is adjustable per software. ---------------------- MSI GTX 675mx: MSI 675mx (2GB) - 80.04.58.00.14_'OCedition'_rev00 -> higher software overclocking limits, tweaked performance at high clocks. MSI 675mx (4GB) - 80.04.58.00.0E_'OCedition'_rev00 -> same as above, vbios for 4GB card (!) ----------------------- Clevo GTX 675mx: Clevo 675mx (4GB) - 80.04.58.00.05_'OCedition'_rev00 -> higher software overclocking limits, tweaked performance at high clocks. ----------------------- ASUS G75VW BIOS: - 660m at 1000MHz core / 1400MHz memory - additional BIOS menus http://forum.techinferno.com/asus-gaming-notebook-forum/2538-%5Bg75vw%5D-modified-bios-vbios-higher-overclocking.html ------- Donation link in case you want to buy me a beer Thanks and cheers! *** FILE DOWNLOAD LOCATION:

Imo there's only one way to go for a desktop system... a custom build.
