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
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.

1. Thats very disturbing about the VRM temps. Still 80c under load isnt bad. My previous 2 boards show well over 100c under load and about 100c at idle (see second image)

Here's the thing. Isn't the thermal pad and heat sync supposed to be hotter than the components its cooling since its drawing heat away from the VRM? And isn't the sensor that's giving the reading right there by the VRM and more accurate? ....... right?

2. Open Hardware Monitor shows that whenever the PC resumes from Hibernate. Restarting the program shows the correct speeds...

The sensor I think reports the temps at the VRMs and not the heatsink.  If the heatsink is at 80C and the VRMs are at 55C, then the heatsink is working well.

Suprised really if the delta is infact that large, heatsink would be working very well.

Anyways, I seem to have stumbled into a small problem while messing with my BIOS, apparently, my UD3 enabled HPA on Disk 2:1 (WD Black, which is in a RAID 0 array).. and yeah, it's sort of annoying my OCD- even if it's only shrunk by a mere .01Gb according to the controller. Going to go get HDAT2 in a little while to confirm it is HPA, but I have this strong hunch lol.

About 15 minutes until my computer is freed up again.

Update: It was infact an HPA, apparently the older BIOS versions to the UD3 let you enable that. Well, I learned the hard way, and it cost me a Windows install. Lol mad.gif

weird thing happened a couple nights ago. PC was in hibernate mode and when I tried to power in on nothing happened. I stopped just short or resetting the BIOS, I unplugged the power, cycled the PSU toggle switch a few times then it just turned on.

On 2 other occasions while it was in hibernate, the PC powered on then shut back down.....

Has anyone tried the new F6 BIOS for the 970A-UD3? The description says "Modify ET6 function". I presume this has something to do with EasyTune 6, but what does it do?

Probably the same fixes as F12 on GA-990XA-UD3.

Not 100% sure what the "ET6 function" they talk about is a reference to, but with this particular board, F11 was unstable as hell, and F12 was much better, at least with my system. The only difference between F11 and F12 was that same "ET6 function", so something good came from it, haha

Edit; on a side note, xd, which BIOS are you using?

I don't believe I've taken to any BIOS update in awhile actually, I might still be on F7 out of laziness o_o

post #1070 of 3278
Oh I was just curious haha, F7- haven't really messed with that one much.

I am definitely thinking about going back to F10 myself, but F12 does have the VRM protection, and that is kind of nice. F12 works well (aside from the very rare, random post-fail over my memory timings), but I still say F10 has been the most stable BIOS out of all of them for my system.

What do you think? Is the VRM protection that necessary? I mean, so far I've not run into any issues with my board overheating, or even coming close to it.
