Can't seem to get any overclock on my A8N...

[BigGreenMat]

Alright I figured someone here might be able to help me. I just upgraded my old s939 system with a x2 3600+ in hopes of lengthening its life a bit. Now my rig is as follows

A8N-SLI Deluxe mobo BIOS rev. 1016
Mushkin 2x512mb 2 2 2 5 DDR400 RAM
Athlon x2 3600+
Galaxy GeForce 8800GT

Now here is the problem I want to get my CPU clock to at least 2.6 ghz to help it at least keep pace with the 8800GT, but I cannot even get my board to overclock to even 2.1 despite relaxing memory timings, upping voltages on memory and CPU, changing my memory to FSB ratios, or anything else. Does anyone with experience with my mobo have any suggestions? It is really frustrating as it runs ROCK SOLID at stock speeds and I can't see what is putting a halt on my attempts

Did you disable Cool & Quiet in the BIOS? When you say it will not go above 2.1 is it crashing or no matter what you do it stay at 2.1. If it stay at 2.1 it could be that you still have Cool & Quiet on.
