Gigabyte HD 7950 on Intel DX58SO not working !!

[abhadi]

Hey guys,

i recently got a Gigabyte HD 7950. when i installed it my system, it didn't go beyond the splash screen. I thought the psu that am using was not enough (CX500), so got a bigger psu (GS700). Still the problem was the same.

Am using Intel DX58SO mobo for almost 4 years. It has two PCIE 2.0 16x slots and is working fine with my Sapphire HD 5770. So to further investigate i got my friends' very old MSI p7n platinum and it worked !! The graphic card accepted the mobo or should i say the mobo accepted the graphic card ?? this board too has 2XPCIE2.0 16x slots.

So guys, the problem seems to be my Intel DX58SO. Am stuck !! i've tried updating my bios (the last bios updated for DX58SO - 5/2012), removing and installing new drivers.

Am low on ideas now. pls help !!

Try all steps one by one

1)Remove the gpu , plug monitor cable to mobo's onboard output


2)start pc - go to device manager - display - uninstall whichever drivers is


3)restart pc - put gpu back




or


1)go to bios settings - set primary display device to PEG OR PCI E or you have an Option "Primary Graphics Adapter" and you want to set it to PCIE->PCI->IGP.


or


1)Update your bios to latest

or

1)go to BIOS and switch from uefi to Legacy mode or legacy to uefi



or 1)install mobo chipset drivers

There's no on-board graphics.. So those options are out of the question..
Bios is updated to its latest version...
Did bios reset..
Changed the bios from legacy to uefi..

Still nothing.. Stuck at bios page..

Finally !!!! Found a way though !!!

1. I plugged my old hd 5770 in the primary pci adapter (with hdmi cable attached) and the hd 7950 on the secondary adapter (no video out ).

2. Powered up the 7950 with the 8 and 6 pin cables , the 5770 with molex to 6 pin adapter.

3. Switched on my pc. Both cards started running as expected.

4. Bios worked as it chose my 5770 as its primary display adapter. Bios also showed my 7950 in the second slot.

5. Went inside windows. My catalyst controller shows both graphic cards in the hardware information. (Primary adapter:5770, Disabled adapter:7950) So no problems with the cards.!!

6. To check if my 7950 works properly, i unplugged the hdmi cable from 5770 and plugged it in 7950 while still operating in windows, and it worked !! Display worked fine, videos, games worked.

But still my problem wasn't over, cant keep swapping hdmi cable from 5770 to 7950 every time i switch on my system. so next,

7. I uninstalled all ATI drivers while still using 7950.

8. Restarted the system, with 5770 still attached. Now since the hdmi cable was plugged to 7950 and 5770 still on the board, bios somewhat accepted both the cards and let me through to windows !!! the problem here is that bios needs my 5770 and so it flew past bios and i landed directly onto the OS selection screen ( i use win 7,win 8 and Ubuntu ).

9. Went inside windows and installed the latest drivers.

10. Now my catalyst controller shows primary adapter as 7950 and disabled adapter as 5770.

To sum it up, I still need a latest bios update for my board, till that time i can keep using this AWESOME card. The 5770 is eating up extra power, i have to find a low performance, low power consumption old gen card to replace this. And to go inside bios i have to remove the 7950. (going into bios is definitely not a daily routine. so it shouldn't be a problem)

My cabinet is packed !! Need a bigger case which i will get in due course of time. For now the card is working just fine
