Well if 990XA-UD3 rev.1 and rev.3 are the same mobos could the rev.1 be flashed with the rev.3 UEFI bios?

I am NOT happy with my 990XA-UD3 rev.1. The VRM's and the southbridge are very HOT. I measured them with a thermo probe and multimeter and the VRM's were @ 95C. I rerouted part of the airflow to make the VRM's cooler and it works for now. I can't do anything about the soutbridge though and will have to think of something that will cool it, because the temps there are also approaching 90C and after a few hours of heavy load the pc sometimes resets, and i am pretty sure that it isn't the CPU to blame. The lack of LLC is also ridiculous.

YIKES. Well, first gen FX 8-cores eat power, what voltage do you run?  Perhaps see how tight that VRM heatsink is? It was loose enough on mine to actually come loose if I put enough pressure with my thumb, had to push it down. The latest BIOS has VRM protection so you are probably not in any danger.

 

I don't think so but it might be worth investigating, hm. But I don't think so, there's a chip difference somewhere for sure.

 

Hiv359 if your NB is not overheating (and it probably isn't) I don't think it'd be worth all that trouble.

I'm thinking of just getting an Antec Spotcool for this - after I set up my watercooling NB/MOSFET temps went up by a bit (probably due to the rear exhaust fan being taken out because it blocked the radiator barbs). The NB temps topped out at 78C according to my IR thermometer (prior to watercooling, it topped out at 60C).

1.32v if i remember correctly. But it vdrops quite a bit - in cpu-z it's more like 1.26. I will just try to cool everything down and hope it will not reset anymore.

Hello. I have a rev 1.0 970A-UD3. I recently bought an FX8320. I haven't installed it yet and I'm still using my old Athlon 2 chip. Anyway, looking at Gigabyte's cpu support page for the ud3, it says I need R7 bios for the Vishera chips. I've tried flashing the bios over ten times now and I can't seem to get anything past R4 to work.

When I try to boot up with the later revisions I get blue-screens before I can get into Windows 7 (64bit). When I re-flash to any of the bios between R1 and 4, Windows loads just fine. I thought it might have been due to a conflicting driver, so I went into safe mode and uninstalled any driver related to the board, but I still have the same problems. Finally I tried to start with a fresh install and I unplugged my system hdd and tried to boot from the windows disc and start the install process on an alternate drive, but I get an error before the disc even finishes booting. "Windows failed to start...ect....File: \windows\system32\drivers\fltmgr.sys
Status: 0xc0000221
Info: Windows failed to load because a critical system driver is missing or corrupt."

That was the latest message. I've attempted this four or five times now and I've gotten several different messages like this with different status codes and also a blue-screen.

I'm out of ideas now. Any suggestions?

I seemed to have figured out my problem with the F7 bios, so for anyone coming across this thread and having a similar issue, I just went into bios after re-flashing to F7 again and loaded the fail-safe defaults. After that everything worked and I'm able to load into windows on my original drive without having to re-install.

Hi chaps,

I have what looks like the Rev 1.0 board (although I need to poke around a little more), and have updated it with the latest F13 bios - all seems to be perfectly fine, running my FX 8350 quite happily, have done some burn in tests and whatnot and it stays below 55 degrees under full load (~16 degrees idle, Corsair H80 cooler).

My question is actually Crossfire related - is there a recommended list of bios settings for Crossfire?
post #1398 of 3278
As far as I know there isn't really any bios settings that have much to do with crossfire.

For some reason I cannot set DDR VTT Voltage and Dram voltage at the same time. VTT gets grayed out when I set the Dram voltage to anything but "normal". Does anyone else have this issue? If not what bios are you using? Mine is version F8.

Edit:

Just updated to bios F13, still have the same issue.

I have noticed something very odd on my machine. There is a major discrepancy between what my monitors say (CPUID HW monitor, CPU-Z, Core Temp, and the Bios temps) what the CPU Core voltage is at any given moment.

In the Bios menu where you can set multipliers, voltages, etc, I have my CPU Core voltage set at the stock 1.3750 v
But if I check in the Bios menu for PC Health to view temps and voltages, here it reads 1.4xx usually. This is consistent with what I see in CPU-Z and HW Monitor. However, Core temp and AMD Overdrive tell me my CPU Core voltage is 1.3750 v

Which number should I trust? I want to believe that Core Temp and AMD Over drive are lying to me in a way because at stock voltages I can barely get past a 3.6 ghz overclock without breaking past 60 celsius. In a quick experiment I used AMD overdrive to lower my CPU VID voltage by a bit and everything seemed stable enough after running prime95 for about 10 minutes. It also really helped out on the heat wall. Can someone explain to me what is going on exactly?

Quick machine spec run down
Gigabyte 970a-D3 with AMD x6 1100T and GSkill sniper F3-14900CL9D-8GBSR ram running at 1600 everything else is stock right now.
