Hi All, Sorry this has turned into a PCI slot issue or graphics card issue, im not sure but in light of GIGABYTE (Motherboard manufacturers comments at the bottom of my post!) comments I thought i should post here as i didnt get much from the motherboard thread .... MSI TF III OC 7970

Hi,

Purchased and put together the following yesterday:

i5 4670K/Gigabyte Z87x UD3H/Antec 900 HCG/MSI TF7970/16gb 1866 Gskillrjaws/Samsung SSD/WD 1tb HDD black.

When putting the 7970 in the PCIE x 16 slot (the first slot from CPU down) it simply will not run ... it wont display anything out to the monitor. Strangely '1' time it did and then I went to run heaven benchmark and the computer rebooted as it was loading the first graphical scene.

I switched it to the 2nd PCIE x 8 slot and it worked perfectly. Problem is I want to crossfire 2 of these cards.

Troubleshooting I have undertaken so far:

Switched pcie power cable to card / used both pcie cables to the card.
Removed wi-fi card in first pci slot (next to the PCIE x 16 slot).
Latest Graphics card drivers.
Motherboard has the latest bios / but I did not try the new beta bios on gigabyte's website (as it is a beta/and I had to sleep).
Changed manually in bios to ensure PCIE slot 1 was being used.
Forced in bios disabling of onboard intel graphics (which necessitated a reset cmos as I couldnt see anything at all as no graphic display was working.)

Aside from installing the Beta bios have I not covered off everything?

It works perfectley without a hitch in the second PCIE slot.

CPU / BOARD and CARD are all pcie 3.0 ... so no problem there.

I think I may have a dud board, as curiously 1 time (after what must have been 30-40 restarts in different configurations / 2 or 3 cmos resets etc etc) it worked until it had to run a graphical program.

Please help and assist ... thanks.


---------------------------------------------------------
Update: referred to Gigabyte and got this response .. i can do this but can someone elaborate why this would make a difference?? Especially since its boots in the other PCIE slot without a problem? I hate motherboard manufacturers...

""Thank you for your kindly mail and inquiry. About the graphics card issue, kindly contact your graphics card manufacturer and confirm if the graphics card is UEFI BIOS or Legacy BIOS. Meanwhile, we suggest you may try to adjust a item in BIOS to see if it could help. Please use another VGA card which it could boot properly with your system, and then enter BIOS, [BIOS Features] > [PCI ROM Priority] set as [Legacy ROM].""

Thanks Gigabye great! no help.


 
did you try reseating it back in the first slot again? I installed my 7970 yesterday and it wasnt showing up for some reason only my other card was. shut it down removed it and popped it back in and it worked. It could be that slot on the mobo like you said, do you have anything else to test in that slot?
