Update: I don't know about fixing the FX-series bugs, but F12 has definitely fixed whatever its predecessor has broken regarding Phenom II processors. YMMV, of course- this may be system dependant.

F10 has been my go-to version since release, hosting a wide range of overclocks. Upon updating to F11 my known stable overclocks were suddenly hardlocking/erroring in Prime95 a couple hours in.

F12 definitely brings back some of that stability for me, Prime95 has passed ~3 hours @ 4050 (300x13.5 / 1.425v) and is still running @ 4200 (300x14 / 1.50v) at the 10 hour mark and some change.

Hey, I am having issues with my GA-970A-D3 rev. 1.1. It starts up and runs very smoothly, but when i start doing more high-cpu tasks, such as multitasking (i.e. excel, firefox, camstudio, etc all open at once), my system simply stops responding. The display freezes, the mouse keeps power, but it does not respond. What might be going on? May it have to do with the lack of VRM MOS heatsink on the 1.1?

Thread Starter 

^ It may be simple instability caused by something else.  VRM protection was added with the latest BIOS, but if you're using the downward-blowing stock cooler which provides VRM cooling then any protection would probably not be necessary.  Are you using an aftermarket heatsink?

So, I've been using GA-970A-UD3 for about three months now, coupled with 2x4Gb of ordinary DDR3 PC-10600 by Samsung and AMD FX-8120 CPU. As a cooling solution I use Hyper 212 Plus in dual-fan pull/push configuration and original thermal grease (i.e. one that had been supplied inside retail package of this cooler) as a thermal interface.

Hadn't had major problems so far, but can't tell that my experience with this mobo is as flawless as it was with previous mobos (almost all of them were by GigaByte) I've been using.

First of all, there's extremely annoying BIOS issue (affects all BIOS versions I had tried so far: F4, F5, F6) that it fails to successfully enter BIOS setup utility in case there are more than 7 hard drives available for enumerations through Int13h interface. It annoys me pretty badly as the rig I have here is a bit linux-hosted RAID array consisting of 10 HDDs. Six of them are connected to the mobo's built-in SATA ports, rest four are connected to the Sil3114-based PCI controller card. I've got a special hot-swap bay for HDDs which have a per-HDD On/Off switch. In case I have all HDDs turned on and try to access BIOS setup utility - it merely fails with a "silent" hang after AHCI and Sil3114 HDD detection screens with the totally black screen + blinking cursor. As soon as I turn off any three of hard drives (no matter the port/controller they are connected to) - I have no problems accessing BIOS setup utility. I've got just the same hang in case I have 7 HDDs turned on + attached USB flash drive, so it smells to me like an old good "array index out of the bounds" error. Funny thing is that "Boot Selection Menu" (one you got when press F12 key during bootup) does not experience this problem, but it indirectly confirms my suspects about array bounds displaying seven HDDs + one USB "HDD" for the case when I've got all 10 HDDs turned on and a USB stick attached to USB2.0 port.

Second problem is also BIOS-related: in case I install two PCIe SATA 3.0 dual port controllers (as a replacement for my old good 4port SATA PCI card) system refuses to boot and hangs right after displaying BIOS screen of the second controlled card. Same cards work as expected when inserted into several other mobos, including AM2+ mobo by GigaByte I've been using prior to purchasing 970A-UD3.

Sure, the above issues are not something that would affect "normal" user of this mobo (who would usually attach at max three SATA devices, namely SSD for system, HDD for storage and - optionally - ODD for CD/DVD/BD), but in general I'm a bit disappointed by the "BIOS quality" of this mobo - it had been better with previous mobos by GigaByte.

Third problem is not a problem per se, but rather is a total mess I've got with temperature readings using different utilities under different OSes. Main OS this box is running with is linux with pretty fresh kernel version 3.2. Supplemental OS used mostly for testing and gaming is 64bit Win7. Under linux there are special kernel modules k10temp, fam15h_power and it-87 that allow to read thermal into, CPU power consumption, PSU output voltages and FAN speeds info from built-in CPU and mobo sensors (first two drivers are for CPU sensors, it-87 is for mobo). I would not dive into details about these tools from linux world, but rather just say that the values I get from them seems to be mostly the same I get with AMD OverDrive and HWMonitor under Win7. And here we come to the mess named "what the TEMPIN2 really is?". OP writes that it's the temp reading for VRM, but I'm pretty sure it is not.

Here is why:

a) In case I specify in BIOS utlity to sound the alarm on CPU overhead - it programs channel TEMPIN2 of IT8720F chip with the alarm threshold value I had specified. It could be easily checked under linux with the output of the "sensors" utility, and it could be checked under Win7 by setting the threshold to a low value like 60 and executing demanding workload (prime95, multiple instances of SuperPi, Fritz in 8-threaded mode). One could easily notice that PC buzzer would start to buzz as soon as TEMPIN2 would reach 60C deg.

b) If one would inspect values reported by AMD OverDrive he would notice that TEMPIN2 report just the same values as are CPU Core 0-7 temps in AMD OverDrive. Due to a bug in AMD OverDrive it fails to properly report board status when I have all 8 cores of my FX-8120 enabled, but limiting it to 4 cores workarounds the bug and allows to compare TEMPIN2 with CPU Core 0-3 directly in AMD OverDrive at "Board Status" page. Keep in mind that TEMPIN2 is called TMPIN3 in AMD OverDrive. In case you don't want to bother with disabling cores in BIOS to "fix" AMD OD so it would read mobo sensors properly, you could run HWMonitor in parallel with AMD OD and you would easily notice that CPU Core 0-8 temp seems to be the same value as reported by TMPIN2 in HWMonitor.

Accordingly to AMD datasheets on built-in CPU thermal sensors, reported values has nothing to do with the real temperature and should only be used by OS and/or BIOS for controlling FAN speed of the CPU cooling system. Unfortunately it means that we - users of GA-970A-UD3 - are left without the reliable source of the real CPU temperature and have to hope that the cooling system we use is efficient enough and pray that built-in CPU thermal throttling features would keep it from overheating in case cooling efficiency would turn out to be insufficient.

Being pretty sure that TEMPIN2 channel of IT-87 (IT8720F actually) chip is connected to the something, that extremely closely resembles internal CPU thermal sensor, it leaves us with a question where are two other TEMPINx channels of SuperIO chip are connected to. First post on the topic states that TEMPIN0 is connected to the "Motherboard (chipset) sensor" and TEMPIN1 is "CPU". Comparing values reported by ET6 for "System" and values reported by HWMonitor I could agree that TEMPIN0 is most likely connected to the sensor under something, that for older chipsets had been known as "North bridge". As for TEMPIN1 - I'm not sure what it is. Yes, readings tend to increase steadily as I put some heavy workload on CPU and then it steadily decreases as soon as I put CPU back into idle state, so the behavior might resemble so-called "CPU casing" thermal sensor, but it could with the same probability resemble VRM-located thermal sensor as the temperature of VRM MOSFETs and coils would raise the same way CPU casing temparature raises when CPU is burning watts doing something heavy.

TL;DR I could state that this mobo is a pretty good product I woudl recommend to buy and use, despite it have some minor problems with BIOS that could affect some extremely-specific use cases.

I am having trouble setting up RAID 0, not sure if anybody has tried it before Ive tried every option so far. Any help would be appreciated

Thats funny mine does not sound the alarm when TMPIN2 would reach 60C deg while using Prime95 and HWMonitor if set in the BIOS... im using a UD5 with a 955BE not the bulldozer not sure if that makes any difference or not. Have you tried the Hibernation trick, Upon waking the PC after Hibernation it will cause the TMPIN2 to read 10C deg lower.

hi all just got this motherboard and set it all up...... have a made a huge mistake by getting the fx6200 instead of the fx8120 atleast , reason im asking is i had a phenom ll x4 965 3.4ghz before i got this but was using that on my old ma770t-ud3 , maybe its just me but it doesnt seem as fast , also why wont the bios let me use my memory at 1600 when i use manual settings ........ i luv the board but just hope i havnt got wrong cpu lol

Hi everyone, I'm new to this forum.

I bought this board back in march and I had some concerns about temps and sound quality.

I have a 990XA revision 1.1 board, not certain which BIOS ver.

This is what I've found

1. The audio does suck as reported by other forum members, but there is a fix. Simply change the quality to "Studio Quality" (The default is "CD Quality") and that trashy sound will improve vastly .

2. My temps are pretty good compared to my previous board a MSI NF750-G55. VRM temps were consistently over 110c.

VRM temps on my 990XA is 52c at idle and 61 under load

990XA - At the time of this screenshot the ambient temp was around 87F

NF750 - At the time of this screenshot the ambient temp was around 87F

That VRM temperature sensor is pretty inaccurate, I think I may try and provide a picture of that. Sticking a thermal lead into the VRM heatsink and plugging it into a digital thermometer reads upwards of 80C, even if the sensor itself reports 55 when Im stressing (HWMon) at this clock.

Out of curiousity, why is your reference clock 171mhz? That is sort of odd.
