Gigabyte EX58-UD5 Rev. 2.0 fails to POST Error 26

[BigA]

Well fingers crossed for you and I hope that it all works out.

Okay, I was able to run Prime95 for 12 hours without error as well as Memtest. Problem is if my USB 3.0 drive is connected the BIOS freezes again. Is there specific setting in the BIOS that I would need to change or increase a voltage??

I am also getting cold boot issues as well. It will not POST off a cold boot.

Well, it's officially the board. My USB ports are dead and so are the onboard NICs. Just wish I went with my gut instinct and RMA'd the board as soon as I started having problems. First Gigabyte board and unfortunately it happens. My EVGA board died a few weeks ago and I was hoping to have better luck with Gigabyte. I switched to them because they have the updated Intel ROM. No such luck I guess. Well. for the week it worked it was a great board, but off to RMA purgatory for the next 3 weeks probably.

Thanks for all that helped.

Well sorry to hear the bad news but at least it is definite now and at least you can get something done about it.

I am a glutten for punishment, so I did a bit more research and looked at the LED error code and every time I heard the click it would say 26 and then 2b, and 7f. 2b is a video card issue and 7f is an overclock unstable. But I guess what happens is the video issue rolls into the overclock after it keeps failing even though the overclock is the not the issue (Gigabyte should fix this if that is the case). I decided the swap the video card out with a Radeon 4890 I am currently selling. Sure enough no problems at al in the PCIE16 slot. Then I put the GTX 470 in a PCIE8 slot and it works fine. The problem is if that GTX 470 is in any PCIE16 slot the system will not POST most of the times and I receive the 26, 2b, and 7f errors; however, if I put it in a PCIE8 slot it works completly fine.

So basically, everything is working the GTX 470 in the PCIE8 slot. I have no idea why the USB and LAN stopped working. I am assuming they share the same bus with the PCIE lane. Is there a compatibility issue with the GTX 470 and these boards that you know of? I am thinking no. Either way, I am just going to replace the video card as that is much easier than the board.

I ma not aware of any compatibility issue with that card but I guess it has to start somewhere! There seems to be many more problems with the nVidia cards than the AMD Radeons and that is one reason I tend to stick with them.

I prefer the ATI cards, but I need the GTX 470 for Adobe Premiere CS5. It has the built in CUDA for rendering. I should have the replacement tomorrow. I will see how it works out. I contacted Gigabyte suppport to see if they heard of any issues as well.

Please let us know how you get on as there might be other members in a similar position either now or in the future.

I received the replacement video card that has fixed the issue. It works fine in the PCIE16 slot. It was only a week old, but like everything else they can be defective too. Just glad it wasn't the motherboard. Good thing is that I feel like I am wiz with all the BIOS settings now with Gigabyte. I switched over from an EVGA board and it was a bit different.

So if anyone receives error codes 26, 2b (especially), and then 7f it mostly is the video card.

Thanks again.

Happy to hear that the replacement sort the problem out for you. Now you can get on and enjoy using the system rather than ripping it to bits!
