Second GPU running at 100 C and throttling to stock clocks --- 7970m Crossfire P370EM

Recommended Posts

Helllo everyone,

I have a Clevo P370EM running 7970m in Crossfire. GPU1 never crosses 72 C at full load but GPU2 takes about a minute to spike all the way to 100C and throttles down to the minimum clocks and my FPS are suddenly half as before.

I cleaned everything inside, reapplied thermal paste and bought a cooling pad. I also flashed a Prema Mod for the fan control and run them at full speed. This dropped the temperatures by a few degrees and both cards run at around 30 to 35 C each when idle. The problem with GPU2 remains.

I'm attaching a screenshot of MSI Afterburner log after running Heaven Benchmark 4.0 at full settings. As you see, I'm running stock core and memory clocks.

I looked in other threads to find a solution but even though I found some useful suggestions for other temperature problems I couldn't find anything that would relate directly to my issue.

Would anyone be willing to share their expertise and help me out with this? :32_002:

      Привет. Помогите, мне грустно.
      Существует clevo p150em, недавно обновленный с 7970 до 8970 м (от 150 см)
      Bios, R.2.0 / 1.02.17EC v3b / 1.02.11EC.
      Когда он был установлен 7970 м, в BIOS на линии gpu это было 7970 м. После установки 8970m, NVIDIA пишет вместо 8970m.
      Драйверы на 8970m не установлены, либо синий экран, либо ноутбук замерзает. Windows 10 1713.
      Я пробовал разные версии драйверов, все равно. Что вы посоветуете?
      8970m vbios  VER015.041.000.000.044964 BR44964.009 it s DELL? 
       
      ps. when I bought 7970m for a place of 670m. At 7970m there was also a problem with the drivers, but I somehow skipped it.

      Hello forum, i have a problem.
      I own a P370EM it had a 7970m but its not working anymore. I bought a GTX 770M to replace it. But after changing the cards, after POSTing the screen goes white even though the pc boots into windows normally. What may be the issue?

      Hey all, just got my m17xr4 and put my 980m from my m15x (old) in it. I was able to score much higher graphics score in firestrike even though it is a much older machine. I made a custom vbios for the m15x to get rid of any throttling, and am in the process of making on for the m17xr4 but I'm wondering if there is anything else I have missed to deal with the throttling. any help would be appreciated

      Hi.
      I have a Clevo P370Em laptop Currently, BIOS Revision: 1.02 PM v2 Is there another version? Or is it possible to activate the I7 cpu's integrated (HD vga) video card somehow? AMD's video card is the biggest I can put in crossfire. There are currently 2 HD 7970s in the machine. Thanks.

      Okay here is what's going. I have a alienware m18x r1 running an amd 8970m, I wanted to upgrade it to crossfire but I could see a 8970m was more expensive than a r9 m290x
      So I decided to buy a r9 m290x and see if I could make it work in my alienware and also run crossfire.
      Even though many shops refused to sell me one because the didn't think it would work in an alienware m18x r1 only in the r2.
       
      Here is the whole process.

      No post bios showing when booting, so impossible to enter bios menu, but can boot into windows 10 with no problems.
       
      19/08/17 23:20
      Because I haven't deleted the old AMD 8970m the r9 m290x shows as a 8970m with no problems.

      First performance test was a success. The r9 m290x changed p-state normally. The gpu fan start spinning normally. But because of no thermal paste, the test lasted 20 seconds because the temperature raised fast.

      Created a backup of the vbios version
      015.032.000.004.044450
       
      20/08/17 00:10
      Flashed a new clevo vbios version 015.032.000.003.044465
      Caused the card to be corrupted and resulted the 8 beep code.
       
      20/08/17 00:35
      Finally managed to flash the back and return the graphics card to its original state.

      20/08/17 00:50
      Flashed a new dell vbios version 015.046.000.014.045579
      No change in behavior
       
      20/08/17 01:07
      After trying multiple vbios with no luck I finally found one.
      Dell vbios Version 015.041.000.000.044966
      Brings back the post bios screen and I can now enter the bios menu through the r9 m290x.
      Note: This vbios reduce the cards performance from 900 mhz to 850 mhz
       
      20/08/17 01:21
      After more testing I found one that is working with no limits.
      Clevo vbios version
      015.036.000.005.044618
      Brings back the post bios screen and I can now enter the bios menu through the r9 m290x.
      This will be the vbios I will keep at the moment.

      I completely uninstalled the previous driver and installed the newest driver. The graphics card is recognized as a 8970m but works normal.

      21/08/17 20:15
      I have inserted my old 8970m in the secondary slot and will start testing crossfire.
       
      21/08/17 21:45
      I have found out that the fan for the secondary fan did not spin. The is a cable that have felt out. I will fix it now.

      21/08/17 22:00
      In my try to test crossfire compatibility, I installed the newest AMD driver 17.7.2 but as soon it installed the driver for the secondary card it caused black screen. Only booting the computer in safe mode brings the screen back.

      21/08/17 23:02
      After many frustrating hours I finally managed to get crossfire working with the r9 m290x as the primary card and my old 8970m as the secondary.
      I have flashed the same vbios on both cards so the r9 m290x shows up I device manager as a 8970m.
       
      I first installed AMD driver version 16.2.1
       
      Then installed AMD driver version 16.6.1 in order to play battlefield

      21/08/17 23:20
      First test run in battlefield 1

      21/08/17 23:40
      Battlefield 1 is flickering bad, this can maybe be solved with a new patch or driver.
      Other games I have tried is working perfect with crossfire on.


      Now what I would like to try is somehow force the r9 m290x driver to be installed and see if it will make it possible to run the latest AMD driver without getting a blackscreen.
       
      I have tried to edit the .inf file like you would do with nvidia but no luck.
      I have also tried to figure out how to edit the device id in the vbios, but I find it too complex.
