Currently, here's are my settings:
HT bus: 220
Vcore: 1.467 (my mobo goes 1.4, 1.425, 1.467...)
RAM: 733 (from 667)
RAM voltage: 1.95 (from 1.8)
Timing: 5-5-5-15 (from 4-4-4-12)
Any idea how I can improve things to keep my CPU at 3.41? Also, why does it need to be 8 hours?
I never use my computer 8 hours in a row (not counting leaving it idle/screensaver), let alone stress my CPU 100% for that long.
P.S. I don't think it's a RAM issue because Memtest passed fine. If anything, I'm going to see if it's stable at lower voltage: 1.9.
The 8 hours is somewhat arbitrary. The longer it runs, the more sure you can be that it's stable. Supposedly the program OCCT can run for less time to test for the same level of stability. I'm not sure how true this is, but I do prefer OCCT myself.

Price is so good, I wonder if it could actually be that much better than the stock. What do you think?
Memory timings are currently at 5-5-5-15-25-2T. ( I should have gotten the 4-4-4-12 version of this memory) How would you suggest I loosen them? Should I go directly to 6-6-6-18, etc or should I change one at a time like going 5-5-?-??-??-?T? Where would you set them to start?
I think I will try the timings and test, then try a small volt bump as LoGGi! suggested and test.
Thanks for all the help! This forum is great!
Most of those reviews are fairly old. Since the Freezer Pro came out there have been a few coolers that I think are better and at a reasonable price. I'm mainly talking about the HDT (Heatpipe Direct Touch) coolers such as the Xigmatek HDT-S1283 and OCZ Vendetta 2. Those coolers can be found for around $35-$40 and perform on par with the Thermalright Ultras which are sold for $50+ without fans included. Just to give you an idea, I was testing 1.55v at about 3.5Ghz and my Xigmatek was keeping temps below 55C. It's pretty impressive. The 6000+ was not impressive however, my chip is surprisingly unwilling to OC lol.
For the memory, just increase the timings to 6-6-6-18 while testing for max cpu speed to be sure it's not your memory. Once you're happy with your cpu clock then you can try to optimize your timings and RAM voltage.
