No PEG on M17X-R4 with nVidia GTX 980M

Recommended Posts

Hi, I installed a new GTX 980M in a M17X R4 but there's no way to get PEG mode working.

First I tried to follow instructions from Lee James Wood (who sold me the card), using the stock A12 BIOS but it didn't work.

He stated I shouldn't stay on Windows 10 x64 with Optimus mode because it'll cause issues and probably damage my new GTX card because of erroneous temperature readings, so I have to try harder.

I tried with an unlocked A11 BIOS and then following J95's instructions:

Unlocked BIOS.

- Unplug power cord

- Remove battery

- Hold power button for 30 seconds

- Remove CMOS coin battery (next to GPU fan)

- Remove gtx 770m -> 2 screws only, there's no need to remove the heat sink.

- Reinsert CMOS battery

- Plug power cord

- Power on -> Beeps -> hold power button until shutdown.

- Power on -> F2 -> disable the integrated graphics - Second Advanced Menu -> Video Configuration -> disable IGP -> set display to PEG -> Exit menu 'Save Without Exit' -> shutdown.

- Reinsert gtx 770m.

- Power ON -> F2 -> shutdown.

- Reinsert Battery.

...but it didn't go. In a different way.

By the time I power on the notebook after reinserting the card back, I obtain a black screen and beeps.

I tried the procedure step by step, first by setting in the BIOS the mode to PEG and disabling the integrated graphic card.

then I tried by setting the mode to PEG and setting the integrated GFX to auto instead of disabling it.

No way: always black screen and beeps. :apologetic:

Actually the video cards are in SG mode, and nVidia Optimus seems to work right.

I'm not enough into video card tech to judge but mr Wood, who's much more expert than I am, told me that using SG mode the dedicated card signal and management go through the integrated GFX; because of this there's the risk the dedicated card isn't correctly managed, especially regarding temperature readings. Nothing wrong except slower performances.

Has anyone a piece of advice for me?

Has anyone with a similar hardware configuration managed to use PEG mode? And How?

It seems there's no other thread regarding this matter, and that I'm not the only one with this problem.

Thanks in advance!

Haha I am very new to this forum, this is my first post, but I just got through getting mine configured with the help of phobos1984. Were you able to flash the unlocked A11 BIOS? Since then have you gone into your BIOS and tried to change the Video Settings?

Yes to all, as you can read in the OP.

But it didn't work: black screen and beeps.

assuming you flashed A11 unlocked do this:

- go to the bios (press F2 repeatedly on boot), load the default settings. Now Save WITHOUT exit. Go to Boot menu -> "Boot list option" UEFI -> "Load Legacy Option ROM" Disabled -> "Secure boot" Disabled-> " Windows 8 Fast Boot" Disabled. Now go to "Advanced tab" -> "Video Configuration" -> "Primary Display" PEG. Now go to "PCI Expless Graphics" -> "Aways Enable PEG" Enabled. Save and Exit bios.

From here you have completely disabled your integrated graphic card and will run only on Nvidia. Keep in mind that you will need to use DDU to remove the old Nvidia drivers and then install the modified one. You will need to disable the DSE in Windows in order to install them. When installing the drivers install only display adapter drivers and PhysX, nothing else.

PS. It is not required to pull your card. If you are stuck with 8 beeps just remove the CMOS battery and hold down the power button for more then 30 secs. Do it with your clock on hand 'cause it seems an eternity. Then power on and do the steps above. Only pure UEFI will work.

Thank you!!! :triumphant:

I don't know how or why but this time it worked!

I was quite sure I've tried all and every option, even the configuration you posted, but I was wrong.

As I said I already had unlocked bios A11 correctly flashed. Now the system is in PEG mode, there's only one video card and with a different hardware ID from before (in Windows Device Manager) so I had to mod again the drivers and reinstall them but then everything went smoothly!

Performances are improved greatly since before: I'm impressed I can play The Witcher 3 at Ultra configuration with such a great framerate.

Thank you again, phobos! :Banane47:

P.S.: now max card temperature can reach 88°C. What about yours?

You are welcome!

I never saw mine over 70. But have to say that the most demanding games I run so far are: Watchdogs, Shadow of Mordor and Crysis 3. Don't know how bad/heavy Witcher 3 is.

How did you get the second advanced menu in BIOS?  I have BIOS A13 and there's only 1 advanced menu?

      Hi everyone. I have had a bit of search around but I have not found anything yet pertaining to my issue. I have an Alienware 17 R1 (Late 2013 model). It originally came with an i7 4900, a GTX780m, 120hz 3D panel with intel graphics disabled. I have just got a Dell GTX980m 8GB (BIOS 84.04.2F.00.79 - Device ID 10DE 13D7-1028 05AE) and put it in and it works fine getting into windows and running 2D. However, when I run any decent 3D the graphics constantly hits power limiter and downclocks to around 800mhz. This is confirmed to be power limit in gpuz perfcap reason and this happens regardless of temperature. Running a Unigine benchmark has actually showed the card's performance to be just lower than the 780m I replaced. Using HWiNFO64 I have found that the GPU is being limited to 80 watts. It briefly goes up to over 100 watts but drops to 80.

      Power Supply is 240 watt

      This laptop always runs off mains power and the battery only lasts a few seconds regardless of apparent charge.

      I should also mention that I have tried,
      Setting nvidia control panel power management mode to prefer maximum performance.
      Disabling Battery Boost in nvidia geforce experience
      Setting windows power options to high performance
      I have even installed a fresh windows 10 on a different hard drive and have observed the same result.

      Has anyone else done this upgrade and had no issues, are there any known fixes, is this card faulty or just not going to work correctly.

      Thanks

      Hello all
       
      I have a Clevo P370EM3 laptop with a pair of GTX 680Ms in SLI mode and have never been able to get Linux to work properly with full acceleration and without tearing. I have tried every xorg config I can find, and even all the modifications from the nvidia configurator to no avail. Has anyone been able to get these things to work 100% in Linux? I have typically used ubuntu based distros, including Mint, and every available driver version from the repositories, but can never get it to work quite right.
       
      Thanks for any help anyone can provide. It is killing me to run Windows on this machine because of these issues, and I am almost to the point of installing the inferior 7970 cards.
       
      Have a great day

      Help! I created a BOS BOOT DISK and use legacy to boot in DOS.   But it is saying that "An operating system wasn't found".   I have extracted all the files (the alienware m18x r2 a11 unlocked bios) into my external hard drive (format: NTFS)

      The new leak of NVFlash version 5.513.0 with their new RTX GPU (Turing) support is now available in our download section. This includes support for NVIDIA's new RTX 2080 Ti, 2080 and 2070 desktop GPUs. As always, use caution when reading/writing vbios files as you can potentially brick your card and void your warranty.
