Motherboard: ASUS M4A78T-E AM3 AMD 790GX HDMI ATX AMD Motherboard - Retail
Ram: OCZ Platinum 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Dual Channel Kit Desktop Memory Model OCZ3P1600EB4GK - Retail
PSU: Antec Signature SG-850 850W Continuous Power ATX12V / EPS12V SLI Certified CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply - Retail
Cooler: Scythe Mugen2

I've never actually overclocked before. I've heard that it will easily go to 3.7 ghz so what I imagine I'll do is increase the multiplier so that it will be at 3.5 ghz? Is that a safe first step? Then I'll adjust the RAM:CPU ratio so that is stays at 1600 mhz. That's about all I've got. Can someone help me as far as voltages and temperatures and testing methods?

I have the same board, same RAM, and even the same processor lawl.

Anyways the most stable set up I have found is the following:

x17 (3.4Ghz) Multiplier @ 1.4V on the CPU (A good OC, stays cool, low voltage, and stable)
x13 on the NB with a .25V increase
RAM at 1333 at 6-6-6-24 1T

The RAM seriously runs better at 1333 over 1600 with the Phenoms. Not even kidding.

That'll be the best compromise between stability and performance. I am able to get it to 3.7 and 3.8 but the computer likes to throw out tons of BSOD's. Increase the voltage and it will be stable, but that comes at a cost of durability, stability, and heat.

And BTW make sure Cool and Quiet, plus CPU Spread Spectrum are disabled.
