Thanks man. I know the mobo is great for OCing, but I can't figure out where to go. When I go to bios, I only have options for bus speed and voltage, no dividers or anything. I could probably max this out around 2.7 GHz if I could set dividers and the htt stuff.

alright, under advanced chipset ... goto HT Frequency and press enter... It should either be 1x, 2x, 3x, 4x, 5x OR it maybe 1000,800,600,400,200

1000=5x
800=4x
600=3x and so on
do dividers, goto

Dram Configuration and press enter. There you will set dividers and memory timings. under Dram clock.. will be speeds listed. 400 would be 1:1 ratio.. next i think would be 333 and that would be 5:4 and so on.

Try that, I dont run this board nor have ever worked with it..just going off the Manual so you'll have to just guide me guide you.

I didn't mess with the dividers, but I did change the HTT to 4x. I booted up the machine and started Prime95. Been running for a good 5 mins with no errors, but CPU is around 50-53C with 100% use! If it goes any higher, I'm going to have to revert to my old settings, as much more than 50C will kill my CPU (actually it would take about 75 to truely kill it, but 50 would certainly shorten its life). I think I'll get a new after-markter fan to help out with the cooling issue. Based on your experiences, what is the best brand of fan for CPU? What will keep me the coolest for less than $30 or so?

The best air based coolers are the XP/SI-120 and the BigTyphoon, but both are a little pricey.
Check here to get an idea. Most of the heatsinks in there are rather good, especially the ones from Zalman, Thermaltake, and Thermalright.

If you are going to Overclock, you are gonna need an aftermarket cooler.
The two best air cooling solutions in my opinion are the xp-120 and the Thermaltake Big Typhoon, but both at around $55.
For $30, I'd say the xp-90 is a good choice and can be had for $30 at www.sidewindercomputers.com
the xp-90 should fit most if not all boards, the xp-120 has its limits to certain boards.

I'll have enough money in a few weeks for an excellent heatsink/fan (better than the $30 one, so I think I'll wait). I should have at least $60 or so for a good fan and maybe heatsink. I've also considered a system blower exaust. Most of them are pretty cheap, but would they even be worth it? After I get all my cooling done, I'm hooking the case up with 9 blue LEDs (3 in each corner of the front case window). It should look pretty nice when I'm done. I'll post pictures of it and screenshots of performance when I'm all done. I should be able to get the CPU up around 2.7 GHz and keep it below 40C at max load. We'll see...

If you are planing on staying and can get around $60. Get the Big Typhoon over the xp-120.
I hate when I have to take off my xp120 and i always pull the damn chip with it... dont think the big typhon has that issue. Good luck
I think i'm gonna switch, just for that dang reason.

after you get your heatsink and start overclocking again, don't run a ram divider until you loosen your memory timings some. running a faster fsb speed will benefit you more than tighter timings.

Not always true. You need to get a balance between the two after working on CPU speed. In general, Athlon 64s benefit from tight timings due to the low clockspeed, as opposed to the higher clockspeed of the Intels. It's all a balancing act though.
