Bought a new PC. First time using SLI. Some information (if you need more, let me know):
CPU: Intel Core i5 4760K
GPU: Gigabyte GTX 770 OC 3X Windforce (x2)
MOBO: Gigabyte Z87X-D3H
PSU: Seasonic G-650.
Everything went well during the assembly. Screen booted up fine, installed Windows 8 (64bit) and it was spinning like a kitty! Then I wanted to check whether or not SLI was doing something, but found I could not get to its settings in the Nvidia tool. I then looked at the Device Manager and saw that only one GPU was being detected. I undertook the following steps to identify an issue:
1) Used both card (seperately) in the PCIEx16 slot. They both worked.
2) Used both card (seperately) in the PCIEx8 slot. The display would not turn on.
3) Used both cards (together) in the PCIEx16 and PCIEx8 slots. In both configurations (so alternating). Only the card in the PCIEx16 was being detected.
4) Updated drivers to latest NVIDIA drivers. Did not help.
5) Looked in BIOS for any PCIE settings, but could not find any besides setting the init display?
6) Tried updated BIOS to latest version. I'm running F3, latest one is F6. I download the files from the site, but it won't run under Windows 8 (which is to be expected, see further)
7) Tried to @BIOS tool, but connection to all servers failed.
I did all this with the GPU card being screwed into the case and not screwed into the case as to avoid the back of the card being pulled out of the slot somehow. It did not impact the tests at all.
I also since read, that you can update the BIOS via USB by putting the autoexec.bat, efiflash.exe and Z87XD3H.F6 file on a USB stick and using QFlash. Is this correct?
I'm really beginning to suspect that the mother is defective. It does seem strange for a brand new board though... Are there any other things I can verify or should I rma the board?
Contacting the supplier they said that the motherboard could be defective or there is some overclocking settings in the bios needing looked at.
Thanks for your time!
