What ram do you have?
The first thing you need to do is find what max FCLK you can run on your cpu. Because your FCLK determines what max speed you can run the ram at.
I'm not sure what FCLK's are achievable on the 3600 series.
Start with putting the FCLK to 1800MHz and leaving everything else on defaults including leaving your ram at it's base speed.
Boot in to windows and see if everything is OK. For me it's quite easy to know if something is wrong because if I adjust the volume on windows I get a garbled sound.
If all seems well, load up a game and play for about 20 mins or so.
No issues?
Then increase the FCLK to the next value up and repeat the above.
If you get any issues, garbled audio, pc resets, game crashes etc... then the FCLK is too fast.
Lower it a notch and repeat the above until you find the max speed the PC is happy at the highest FCLK the CPU can manage.
Lets assume now that your FCLK tops out at 1800MHz. Your ram speed is 2 x FCLK.
So you would run your ram at 3600MHz. Assuming now that your ram can even run at this speed!
This video will help you once you know what ram speed to run at. (He suggests fast timings, but if you have any problems go with the safe timings.)
In essence. Set your primary and secondary timings and set the dram voltage in the BIOS. Everything else should be handled by your motherboard.
The fast timings didn't work for me from the dram calc, but the safe timings do.
