Same page as the link provided by Hurricane, a bit lower, you can also see the effects of motherboard warping on the mosfets:

(Just in case you have warping too).

Earlier I was on mobile and quoted undervolter incorrectly and it deleted my text. :/ I'm considering replacing the VRM thermal pad with something of a little higher quality. Also, I don't want to spend a whole lot of money.

I was wondering, does anyone know much about the stock VRM thermal pad? I couldn't out anything about it with some basic internet searches. It seems thermal pads are rated w/mk. Does anyone know what the w/mk rating is on UD3 thermal pads? I'm guessing it's probably under 5w/mk, but don't know.

I tried replacing the VRM thermal pad with thermal paste, but I found that it was difficult to get even contact between the mofsets and the heatsink. I posted pics several pages back.

As you can see above I was finally stable on both program.Now I'm gonna go for memory overclocking.
post #12145 of 12377
Well I've done some memory oc. I have corsair vengeance pro 16Gb 1600mhz 9-9-9-24. 1.5 v. I've tried 1866mhz 9-10-9-27 and 2133mhz 11-11-11-27 1.65v. I didn't see that much difference. I will share the pictures soon.
post #12146 of 12377
Coz in reality, it's not an Overclock.

RAM OC is misleading. But to give you an idea, if you can clock the RAM to 1866 from 1600 without modding the timings, that's an Overclock.

Or tighten the timings from default maintaining the clocks.

Latency increases with timings. And bandwidth cannot justify the loss more often than anything.

Thank you for the tip. First of all, I will go with higher frequency with as tighter timing as possible. But if not do you think is it better going for higher freq. with higher timing. or tighter timing with low freq. Thank you indeed.

Question: does anyone here have the Gigabyte 990FXA-UD3 R5 board? If so, are you experiencing a badly overheating unstable mother board? I just got this thing back from Giga after a so called "RMA" and they claim there is nothing wrong with the board after testing but this thing is crap.

I'm gonna take it apart myself and see if there is something that I can do to try and get this thing to cool down. It won't run an FX-9590, FX-8350 at stock. Over heats terribly. So I installed my 1090T in it and still it overheats horrible and it throttles...........................at stock!! If I can't get her straightened out I'll have to toss it cause it's useless. Brand new board and it's crap.

Has anyone found a solution to the over heating problem? Or are these boards just doomed?

Every one of there boards has one problem or another that if I can't find a way to mod it or find a work around they don't work as they should out of the box. Last Giga board I will ever buy. I'm done.

One thing you should look at, is motherboard warping, like mentioned earlier. See here illustrated:

http://www.overclock.net/t/1023100/official-gigabyte-ga-990fxa-series-owners-thread-club/5090#post_19872718

Another case with Gigabyte board i remember in the forum, was someone with GIgabyte 78LMT USB3 that could barely stay at stock clock, while previously he could overclock a bit. It turned ouf that he had one burnt mosfet, which was revealed after removing the thermal pad. Just saying, these are possibilities that have happened before in the forum.

Yes, your ram is designed to run at 1.65V, sometimes Gigabyte boards need a little more voltage in BIOS in order to get 1.65V in Windows.

Here is the post i found for you about the vrm throttling: http://www.overclock.net/t/1023100/official-gigabyte-ga-990fxa-series-owners-thread-club/5090

This guy spend A LOT of time in these boards and Gigabyte simply refuses to answer him or are simply incompetent on making a decent board..

I am sure as hell never buy Gigabyte ever again...

Good luck with returning your board man, i really hope they will help you because the incompetence of Gigabyte is becoming the most taxing to say the least...

If you have any problems with returning the board, feel free to post about your conversation with your retail store, perhaps we can help you since this problem has to be dealt with shortly and swiftly.
The seller only has Gigabyte 990Fxa UD 5. Do you think has that mobo better oc capability?
