OC a e2180 & 8800GTS

[nicksource]

Got a couple of questions.

28C idle, stock, good starting temperature on air?

What's a safe overclock on air? (Arctic Freezer 7)

The CPU/Memory ratio is on default in the bios is there a particular setting this needs to be at?

With my 8800GTS, it's showing 1300mhz in one place and 800mhz in another, is this because of the RAM?

Thanks.

That temperature seems fine. General rule is not to let it go over 65c on load (when running prime or orthos). Although I've never done it, I've seen loads of people that have got their E2180's to 3Ghz no prob with that cooler. You could probably get it to 3.5 if you tried, but you'd have to keep an eye on your temps.

As for your GTS, I think the 1300Mhz is the shader clock, and the 800Mhz is the RAM speed (the true speed anyway, effective is 1600). You should have another one somewhere saying 500Mhz (that's the core), unless you got a pre clocked version.
