I'm not sure that stability is my problem though. I'm no authority on overclocking, but in my experience 10 minutes of prime95 without an error means that at most it just needs a small bump in vcore to be fully stable. I have gone as high as 3.8GHz at 1.39v without an error but temps would get too high after 5-10 minutes load.

According to this review http://www.hardwaresecrets.com/printpage/Zalman-CNPS9900-MAX-CPU-Cooler-Review/1176 the 9900Max, which is almost the same as 9900LED, is better than D14.

I'll try out the stock cooler, which looked pretty beefy compared to past AMD coolers, to see if it gives any better performance. Not sure I'm ready to shell out another $70+ for a cooler right now.

I wouldn't trust that test alone, do some more research.

I have done more research and I now have a H212+ on the way. Hopefully, that will work better.

I just thought I would follow up on this: it was absolutely the cooler. I can't believe how much the Zalman sucks.

With the H212+ I can get up to 4.0GHz with 1.44v easily, which is right at the point where temps begin to reach 60C. OTOH, 3.9GHz only takes 1.4v and load temps are in the low 50s, so that seems like a good compromise for everyday use.

Yeah man it makes you rage when you read reviews about how good something is only to find out Zalman sucks! Cheers for the follow up.

Absolutely! Going back to that review, I generally like Hardware Secrets, but I noticed that it's the same guy who goes all the CPU cooler reviews and he has some really inconsistent methodology. However, he's not the only one praising the Zalman!

1st you must put more CPU NB voltages like 1.3/1.35v (MINIMUM to 3GHz NB).
2nd for 4GHz CPU voltage of 1.45v / 1.475v is enough. (Depend on chip) The standart ones can do that. But if you got the crappy one you can't at all.
3rd the problem is 16GB of ram. This ram is limiting your overclocking by 5~10%.

Sorry but I have to disagree with what you wrote. First of all, overclocking was done at 8GB and tested at 16GB to make sure RAM was not affecting my OC—it was not.

Second, I was able to do 4GHz/3GHz NB with even less voltage than you indicated, and it was stable under preliminary testing. However, temps were reaching 61C after 30 mins of Prime95 so I decided I'd scale it back a notch, given that this computer will see near 24/7 use in not the most ideal conditions, due to my wife needing a lot of heat in the Winter.
