EDIT!


It seems to work now.

But Radeon-Crimson-15.12-With-DOTNet45-Win7-64Bit doesn't seem to work


Only AMD-Catalyst-15.7.1-With-DOTNet45-Win7-64bit on both rigs works right away.

I am having issues getting it to work in my other rig which has mixed cards. Some are 280X and some are 7970s. The other rig worked right away because they were all identical cards but this one has mixed cards and I don't know how to install the drivers manually. Since in 13.12mod I was given an INF file to put in the drivers folder and update for each display adapter but here there is only the executable file.

It works. THANKS.

Glad I didn't need to install WIndows 8.1

You are welcome ; )

p.s.
Windows 10 can manage 8x290 out of the box.

I have not managed to get xp/7/8/8.1 to work with 8x290, but if s1 is willing to provide me access to 8x290@w7 I can make it work.

Using 14.9 driver.
Initially the 6th card was showing the code 43 error and after running the mod, the device got unlisted from the device manager.
Now showing only 5 cards.
Couldn't retrieve back.
Kindly help.

In case something goes wrong
By default 6xGPU_mod will create backup registry file in the current folder - launch it and reboot.

Also simply re-installing the driver should help - all changes done by the mod will be gone.
However, device disappearing from the device manager.. weird, maybe there is hardware issue.
Thanks. i will do it.
Is there a mod available for 14.9 driver version?

isn't this program related to having a modified vbios. Usually a undervolted bios that works in linux but not windows

This file is part of AMD video driver.
When something is wrong with the hardware usually that's the driver showing as the reason of crashes/bsods.

In this case however probably the driver is causing crash cause it is buggy, or at least I hope that it is.

Windows 8.1 64
4x AMD7990 - 8 GPU
Have no problems running on 14.4, 14.6 etc but i have 6 7990 Smiley Is there any way to start more than 8 gpu on windows 8.1. I have readed somewhere that this is driver issue! When i try to start the system it shows me error in ATIKMPG or something like this. Help if it is possible.

Oh man, do you really need to run so many GPU on 1 motherboard...

Still no success with more than 8 AMD GPU on windows. I think kernel file makes problem, but success with 4 X 7990 and two GTX 970 plus CPU mining - all 45 Mhs on X11 !!! 8 GPU limit per windows is MYTH. This is absolutely not true!!! These days i will buy pcie expander card and will try to add three more GTX 970 Wink In windows 8.1 i did not connect any monitor like it was it windows 7. Everithing works perfect.

Very impressive.  Nice job.  I remember having issues with just 5 before this mod came out...

8+GPU works only on GIGABYTE 990FXA-UD3 Rev. 4.0 (Revision 1.2/2.0/3.0 and GYGABYTE 990FXA-UD5 which i tested have bios issue for 8+GPU). Asrock H81PRO BTC - only 7 GPU!!! I think this board have bios bug or something like that. Till now GIGABYTE 990FXA-UD3 Rev. 4.0 is best for support multiple GPU but do not try to switch more than 10 GPU - South bridge will die !!! 2 of my board are death now, trying to switch on 11th GPU Smiley

Not compatible with 14.9.Please update.

Sure, however I need access to 6+GPU rig.
Mine are at remote(very) location, also they are equipped with IDE HDDs, and since modding driver requires a lot of reboots and sometimes rigs hang, it is too painfull for me.

GIGABYTE 990FXA UD3 motherboard, FX 8320, 4 X 2 GB RAM.
The problem comes when i install 5th 7990 which adds two more GPUs. Thes it installs driver and after restart when windows 8.1 is loading appears some kind of blue screen where is written that ATIKMPG of something like this file caused problem and windows will restart trying to fix this problem.

And if no AMD driver is installed?
Have you tried adding more RAM?
Do you see BIOS on the monitor?

Anyway, if this is AMD driver issue, maybe I will be able to mod the driver, pm me.

Btw, what's ur motherboard revision?
