PCI-E hardware issues

post #1 of 5
Thread Starter 
So, I've been having some hardware install issues. I've already tried quite a few things in an effort to correct the issue, but haven't been able to solve it.
The hardware specs:
-MSI Z87 Mpower
-4790k
-16gb gskill ram
-Windows 10 Pro
-gtx660ti
-Rosewill 1000w bronze

How the problem started: I purchased a couple of 660 ti's to put in sli, as the r9 I had was apparently failing (regular artifacting and crashing). I uninstalled the gpu using DDU, the display driver uninstaller. Shutdown after the uninstall, and installed the gpu, rebooted. Since then I have not been able to get the pci-e x16 to detect any card.

So, I know the gpu's work, tested on an older board. I can get the regular pci slots to work with my wireless card. It's just the pci-e x16 not working. I was able to install an r9 270x, but the gtx660's still aren't detected. I tried upgrade sfc, dism, windows upgrade process to try to update, fresh install win10, fresh install win7, along with the boards drivers on cd. Nothing works. I see in the registry that the gpu is not listed, but the intel hd4600 is.
I don't think it's the board, I believe it's some sort of registry problem. I had the same issue with the pci slots, but sfc scannow fixed that. For some reason it didn't fix the pci-e x16 slots. scf doesn't detect any issues anymore.

Anyone familiar with this or know what the fix would be?

Hi there!


Some more info would be nice:
  • For a start, when you say that you cannot get the 660s detected you mean that the system won't even post w/o using integrated gpu?
  • Also, are those 660s you bought in working condition? nvm, re-read your post biggrin.gif
  • Have you tried one 660 at a time?
  • Do you have any other cards that might be using pcie lanes from your cpu?

You could always try loading cmos defaults and see if there's any change, even updating bios in rare occasions could solve such problems...

The system will boot, but no display from the gtx 660 ti's, whether together or individually. Integrated display works fine with or without the gpu installed.
I didn't have any trouble installing an r9 270x, driver installed fine for that. Bios flash didn't solve anything, tried it several times, even unplugged mobo. It seems to be a registry issue, but sfc doesn't detect anything wrong.

Out of curiosity, have you tried burning a Linux Live CD (Ubuntu for example) and see if you can boot into it with the GTX 660Tis?

 

That would put the OS out of the question if you still don't get any display.

Nope, boot but not burned, but I think I sort of figured out what's wrong. The gpu version isn't the oc version, and I thought it was. The oc version of this gpu has uefi support, but the version gtx 660 ti I have doesn't have uefi support. The Gigabyte site shows a uefi bios, but their vga bios utility won't flash it.
So, I need to flash the gpu bios with a uefi supported version, but \i can't find one. Gpu model is GV-N66TWF2-2GD. The uefi bios I find is for the oc version, and I don't think this card can handle it, nor do I want any overclock through bios flash. That oc flash would be my last resort, but I think it will ruin the card.
Does anyone know where to get a uefi bios for the gpu GV-N66TWF2-2GD?
