How's this ram oc - First one!

post #1 of 18
Thread Starter 
First time ocing ram, I got this by lowering CL, tRCD and tRP one by one untill it wouldn't boot. Then set tRAS and tRC as per this formula I found somewhere:

tRAS = CL+tRCD+tRP
tRC = tRP+tRAS

Raised voltage to 1.750v and ran prime, instantly got errors so raised tRP to 8 from 7, no errors so lowered v.

Is this the right way to go about it?

Looks pretty fair for that kit. Is there no way you can get tRCD beow 9 though?

tRCD is the first one I lowered and it wouldn't boot, that was at 1600MHz though, will try at 1333 now.

Really nothing at all? I think it's rev3, will shutdown and take a stick out to check.

1333 6-7-6-24-34-1T seems stable.

Really I'm just stumbleing around in the dark here. No idea how I should be going about lowering these 5 values. Is there a guide I'm missing?

Rev3 = Micron IC?
Which means you could safely run up to 1.9V - or until the heatspreaders' cooling is no longer effective
