hi,
I've got a new computer (Q6600 and P5QL-E) and it came overclocked from the store (it's an option they give). now my computer crashed (on startup)and reverted back to the original speed. Is it safe to reclock it to the voltage and FSB they used?
btw. it was OCed to 3.15Ghz (ie:350MHz FSB)

That is a very low OC. I would say you could safely do that and more. Read the OCing sticky. I am not sure what CPU cooler they used but if they used anything above the stock cooler you should be able to get a much better OC than that.

How long did it run OC before it crashed? If for only a short time, I would try a fiqure out why it didnt hold the OC. Heat? voltage?

it happened again after it reverted to the original....
I'm using a TRUE 120 and it's not heat... probably voltage, but the voltage was kinda high for this kinda OC (I think) 1.280.
the computer ran for 2 days, it's new.
you think it might be voltage? I'll run prime95 to check

actually your voltage is to low and that causes instability (crashing). Bump it up to 1.3v and see if you still have crashes

KK, I'll try it and tell you what happened. what's an average voltage for 3.6GHz?

The voltage varies from cpu to cpu. You don't want to jump all the way to 3.6ghz either. You need to 5mhz fsb increases at a time.

I didn't exactly get the idea of how to OC, I know that I don't jump all the way up but how do I get there in 5Mhz increments? I go up, up up.... and then voltoge and repeat? or every time I need to adjust voltage? how does it work? (I know how to get by in the BIOS and everything, the workflow is what I'm missing...)

There is a good guide stickied, read that.
