Do these mobos have a power LED?

But yeah, both mobos do absolutely nothing when the power button is pressed.

Rumilsuron: Checking the thermal paste spread is a bad idea unless you have TIM to spare for a remount, because if you remount without reapplying the TIM, it may be uneven and there may be air bubbles.

After I check for thermal spread I always clean off both surfaces and reapply more paste I didn't want to show more pictures of me doing that. I'll go back in my other post and redo the steps for people to get a better idea.

Okay, i just complained to amazon to credit me $20 for my defective 970A's. Would it be worth it to get the 990XA at $120(normally 140)?

^ I paid $120 and recently got a $20 rebate back for mine. At that price, it is an EXCELLENT value board and is flat out better than whatever is in a similar price range.

So why did your CPU core temps drop 6C too? Did you do both those thermal tests on the same day ? Ambient temp change? Do you think the VRM temp affected the CPU temp too? Or was it the other way around?

Im not trying to discredit your work, just seems odd. Perhaps the VRM temp improvement wasn't as great (5-6C) drop idle/load

First post! yay!

Just want to thank Rumilsurion first, he helped clear up some BIOS issues I was having with the 990XA-UD3 on YouTube cheers.gif I was close to RMAing this mobo, saved me a lot of stress!

Anywho, I don't really have much to contribute to the thread, just a few of my overclocking experiences with this motherboard and a Athlon X2 5200+ unlocked to Deneb X4.

This CPU has a low 11.5 multi at stock (locked) so relies completely on the HT ref for overclocking. Thankfully this motherboard has no problem booting at 300 HT ref, best I've had so far is 313 for 3.6GHz. I think it will go even higher but my RAM becomes the limiting factor at these clocks (gonna grab some 2000ish-MHz sticks soon to see if it unlocks any extra headroom!)

For whatever reason I've never validated overclocks with CPU-Z in the past, so lose a lot of the finer details on overclocks *facepalm*. My only proof of sorts is Geekbench currently biggrin.gif

http://browse.geekbench.ca/geekbench2/view/484096
313 * 11.5 1.37v
2817MHz NB 1.275v
1668MHz RAM 1.665v

The only other CPU I've had to OC with this board was Athlon II X3 450. Wouldn't unlock to quad but overclocked at 4.3GHz no problem

http://browse.geekbench.ca/geekbench2/view/432277
287 * 15 ?v
2870MHz NB ?v
1529MHz RAM 1.65v

The CPU temps dropped because I used MX-4 thermal paste instead of AS5. Which I had on before, and the AS5 wasn't finished curing so load temps on the CPU were still a tad high. With MX-4 there is no curing time, so that's why the CPU was much lower between test. The VRM seems to sit around 55-56c now, compared to 64-65c when the VRM had it's stock thermal pad on.

My room says around 20-23c ambient. Depending if the AC is on or off when I took the first screen shot of the Higher temps the AC was on and ambient temps were below 19c and the second screen shot the AC wasn't on.

I would say that I gained between 8-10c drop on the VRM heat sink from changing the stock thermal pad to MX-4. I know this isn't a lot but for someone that wants to push their overclock higher any drop in temperature is a gain.

thx for the clarification. I may do this to the VRMs but not the NB. Im thinking on putting a long zip tie through both holes instead of the plastic clips.. perhaps I can snug it tighter.

@Aaronage, very nice OC's, welcome to the forums! I saw your flickr posts, nice cable management! http://www.flickr.com/photos/aaronage/6109245960/in/photostream in particular. What brand of ram do you have? You missed that in your system specs.

Thanks! I have amended the specs, using Corsair XMS3 2 x 2GB 1600MHz 7-8-7-20 (CMX4GX3M2A1600C7) smile.gif

I was going to use plastic screws and nuts to hold down the heat sinks, but I read up that you don't want to add too much pressure to the mosfets. You can cause damage to the connections. That is why the push pins have springs to adjust pressure.

The North bridge chipset is very small and too much pressure could also cause damage to it. The plastic push pins give just the right about of downward pressure needed.

After putting MX-4, the VRM heat sink didn't move much after that. The paste holds it down a lot better than the stock thermal pad.

The stock thermal pad under the VRM heat sink, felt like rubber and was very thick. So thermal transfer wasn't the best. On the other hand the North bridge chipset used a thinner thermal pad which could transfer heat better. So you might not need to apply aftermarket thermal paste there. I just did it cause I got carried away.
