Matas,

Wow, that's pretty hot. 158F. Given the nice quality case, I'm surprised it runs that hot. Which stepping does your 955 have? I know the one I had before I bought the 1090T BE ran at 4.1GHz at 1.422v and it had C3 stepping.

One thing I have noticed with the 990XA-UD3 is that my 1090T run's about 15% faster stock than it did in my previous GigaByte MA790X-UD4H motherboard. I had Corsair Dominator 1066 Cas 5 (5-5-5-15)memory for my DDR2, and G.Skill RipJaws 1333 Cas7 (7-7-7-21) for the DDR3 990XA, but that isn't going to give you that kind of improvement. It also overclocks higher at lower multipliers than it did on the 790X, so it scales better too. I'm using bios F3 that came with it. I tried F4 and F5, and had heat issues, and for now I'm just going to leave it alone with the F3 bios. It works perfectly. Set at 3.6GHz, it splits the difference in performance between 3.7 and 3.8GHz on the 790X so it's like it's running at 3.750GHz benchmarks at 3.6GHz settings. Very fast machine with only a minimal OC. Great motherboard. I'm very glad I decided to buy it!

Best Regards,
Russ

Theonejrs -> yeh, it's quite hot, but nothing to worry about, as VRMes are high quality low RDS and can run even at higher temperature, somethere xd_1771 mentioned that 70C is recomended highest temp, but just recomended.
It's C3, but I've really high ambient temps and there is no fan in the back of the case, yet. Anyway, maybe next weekend I'll replace stock thermal pad of VRM with Noctua NT-H1 or Chill Factor 3 TIM, will share my results

I don't doubt the improvement in overclocking ability but the performance increase is quite surprising.
My VRMs run particularly cool at between 50-60C during full load situation; it may be due to the rear fan blowing more CFM than the two NH-D14 fans, taking in surrounding air and potentially causing negative pressure cooling on the VRMs.

Hello all

My first post ever around here ever was going to be about how I kept having trouble with my temp readings on this MB. I was going to tell you that in HWinfo, latest version, what is labelled as "Temperature 3" and also usually "CPU 0" (not "CPU" mind you, the one that's on my Phenom not the one from the ITE chip) kept misbehaving:

-Temperature 3 either didn't even show, or when it did the reading never changed whatever I did (browsing, gaming, movie...) and could be all over the place, sometimes 12C (!), sometimes 59(!!), sometimes 129(!!!!!!!). The number would be set from the moment I started HWinfo to the next reboot, restarting the software wouldn't do anything.

-CPU 0, well, would be absent half the time, even though the cpu (10h+ thingie) would appear.

I would try to change settings in the BIOS, to no avail. I got the same results with every version of the BIOS.

Then, right before posting this, I decided to update the BIOS again, because I realized the unadvised version was 9A, and what is now on the Gigabyte site is the 9B. Lo and behold, both my readings are fine now.

Yay! \\o/

So this went from "W.T.F help" to "I have this mobo and everything is fine".

Except (plot twist ) I have a question regarding the MOSFET heatsink. I looked at the post about removing/reapplying thermal paste on the heatsinks and came upon a little kink in the process (beyond ruining my fingers to get the damn things off). If I remove the MOSFET heatsink, remove the thermal pad , apply some not so recent thermal paste, put it back, well the heatsink is just not stable. I can move it slightly back and forth, and when I removed it again (hello fingertips) it was obvious on both the MOSFETs themselves and the heatsink that they were barely touching (paste hadn't spread).

Therefore, are the MOSFETs not aligned on a plane, making any heatsink modification impossible without thermal pads ( ), or is the heatsink itself just poorly flattened/polished? I'm asking because the temp I get from my now-normal reading is around 50C idle, and I don't like it, and I'm not sure what this temp actually measures, and when I do change the stock cooler on my cpu I figure I might as well invest in proper radiators for all involved. Any advices on that by the way?

Aaaand that's it for now.

hi troops!!

i updated to the f8b bios and my machine will not overclock now. it was running happily at 4.1@1.409 vcore on the f4 bios i think it was... seems some options have changed also.... anyone else had this... i may flash back to an earlier revision as im not buying a bulldozer now....

what revision of the bios did the voltage control options etc change

cheers


THE GAME ! ;-)

^ F9B you mean?
Phenom II users not recommended to update to F9X. It seems to be a more FX-suited BIOS. F8 works perfectly, so revert to that.

Sometimes my mobo shows
Normal CPU vcore 1.475v
And sometimes it shows
1.35v
Y is that fluctuation?

To: Kevindeuxieme

When you applied the thermal paste, did you apply small drops to each mosfet. Than with a piece of plastic spread the thermal paste on the chip??

Or did you just apply a thin amount of thermal paste to the heat sink.

Just put a little blob of paste on each chip. Than spread around the chip, you don't need to make it paper thin either, like if you were applying it to your CPU.

If you saw my post on how I did mine. You would see I didn't skimp of the paste, on each chip so there would be enough paste to make contact.

When I did mine it made perfect contact and when the heat sink was attached the paste kept it from moving around.

If you feel none of that is working pick up some plastic bolt and nuts and use them to fasten the heat sink down instead of the push pins. the springs on the push pins might be damaged and is not forcing the heat sink down enough.

No what I did is spread several drops of paste on the heatsink and then spread it manually (with a bit of flat plastic) more or less evenly on the whole surface.

I would have also put some on the chips but as you said I thought I had to do it like with the cpu, as thin as possible. And when I noticed it wasn't stable once put back on, I thought putting enough to make contact would be as bad as leaving the pad.

My problem now is that it took me the best part of two hours from turning off the PC to turning it back on to do this, sooo I guess it will wait until I do change something in the computer. Granted, I lost a lot of time when I accidentally put the mosfet heatsink the wrong way only to realize it as everything was back in and I tried to put the 12v plugs in... fun times.

And about that, anybody know if a 212+ and a hr05 would fit together on this board?

that depends on whether turbo core is enabled or not. For overclocking, disable it.

I never spread before mount. I always let pressure spread it all. You may want to use more tim than usual. Reusing thermal pads isn't a bad thing either; could've just tightened the mount.
