can you tell us where you got your motherboard from and if it came with the latest bios (F8a i think) that makes it totally penryn friendly?
if it does not have this bios, i read a thread elsewhere on toms that said you can download the new bios and flash the board using the E8400.
previously there was much talk about having to have a 65nm chip to use to do all that if the board did not come with the latest bios.
and of course, congrats on your build. very nice.
say, if you completely lose your mind and have nothing better to do with your time, i am curious to know the benefit of a few things... so OC it to the max with the stock cooler and tell us the numbers, then get a thermalright ultra-120 extreme, lap it and the E8400 on a thick flat piece of glass with increasingly finer grades of sandpaper, clean it all up, install it all and use some artic silver, wait a couple weeks and many thermal cycles for the TIM to set up, then OC the hell out of it again, and let us know how much better the numbers got.
