How far can I take this OC?

I have a e6750 at 3.0 Ghz on an Arctic Pro 7 with the default paste (which IMO isn't much worse than AS5). How far do you think I could successfully overclock?

Speedfan reports 16C in both cores after mild use (which is, for my system, around 26-28C).

I said in the parentheses that it was around 26-28 at idle. For the record, though, I do get 16C after a cold boot (although for a very short period of time.)

Do you have a temp monitoring program that works in 64-bit Vista? All three listed don't.

For starters, I would simply set your RAM for a FSB of 400 and 1:1 memory. That will get you close to 3.2Ghz.

Look at your Temps/Volts and go from there.
3.2 would still be a light OC.

It comes down to if the extra Mhz actually gets you muc.
I know I everntually clocked my C2D back just a tad from my highest OC (Which likely was not even as high as I could take it) just so my fan ran more quiet and never noticed a performance difference.

Yes, it can go further. (Less Cores - Less Heat)
Some people have gotten it past 4.0 on air.

Mind you I expect that was outside of a case and a better air cooler.

There will be something like a "Memory Ratio" in your Bios.
It will have a Value of something like 4:5 or something like that.

If you don't adjust this back down to 1:1, you will start running into memory limits far before you hit your CPU limits.

Not need to even make the slightest apology.
You are not the person that owes one.

Thanks for the apology, and also thanks for alerting me about the OC section. I didn't ever use it, so I completely forgot about it.

Oh, okay. I'll try.
