Re: X79 UP4 R9270X Toxic issues.

Confirmed my issues are with PCI-E 3.0 cards only......

Re: X79 UP4 R9270X Toxic issues.

Could this be a issue with the E5 Xeon CPU microcode?? I'm totally out of ideas here, with the exception of purchasing another brand motherboard and see if it has the same issues.

Re: X79 UP4 R9270X Toxic issues.

I had a similar problem with my X79-UP4 and a Sandy Bridge Xeon. Starting with F4 BIOS the motherboard would not detect modern GPUs with UEFI VBIOS. Not my Nvidia Kepler cards, nor my Radeon R9 cards. No settings in BIOS made any difference. I talked to Gigabyte Technical Support for a very long time, they simply don't care and want me to buy X99... Very frustrating to say the least.

Then I tested with a 4820K and no problems. The GPU's showed up as expected etc. Switched back to the Xeon and the GPU's dissapeard. Only worked with he old and terrible F2 BIOS. I don't think Xeons work in this motherboard post F2 BIOS. And the support just sucks. If I buy X99 I will certainly be very careful before I touch anything Gigabyte.

Interesting, I will Flash back to F2 Bios to confirm your findings, if this IS the case it most CERTAINLY is bios related. Giga support told me that their test system didnt matter if it was a Xeon 8 core or not.... Funny how that works huh??

Giga support told me that their test system didnt matter if it was a Xeon 8 core or not....

They told me the same, "works for us". My Xeon is a four core E5-26XX ES.

I sent you a PM also man.

Re: X79 UP4 R9270X Toxic issues.

Funny how when you go back to the 3D F2 bios the E5 2650 ES I am running WORKS WITH PCI-E 3.0 cards.....

Thank you to all the members here that helped me out!!

Gigabyte suppport, you may want to test the operation of E5 8 core procs on your current bios's, along with MORE than 1 vid card configuration...

Just sayin....

Me too. I had BIOS problems from the moment i bought that board. I found 3 BIOS versions to work fine on it with my configuration(from about 40). When Gigabyte make new BIOS version they brake something which worked fine on previous. Also In most cases beta versions work far better than final versions (if work at all). Their BIOS team and support sucks. This is my last Gigabyte board and when the time for switch comes i will use different brand for sure.

Re: X79 UP4 R9270X Toxic issues.

I think the hardware on the UP4 is great. The VRM/powerstage seems very good etc. But the firmware/BIOS/UEFI is not up to par. Real shame. :-(
My board works much better with a 4820K than it ever did with my Sandy Bridge Xeon. I have a Rev 1.0 board, and the Ivy Bridge Xeons are not even supported on it. Need Rev 1.1 for that, so I guess this board is a bad idea if you have a Xeon.

Re: X79 UP4 R9270X Toxic issues.

Mine is a revision 1.1, just cannot figure out how my setup will work with the newer bios's with pci-e 2.0 cards, and not 3.0 cards. Then I can flash back to the old 3D bios, and the 3.0 cards are recognized just fine?? I have a 3930K coming also, we'll see what happens with that processor...
