You want to talk to Leeghoofd for information on cooling a striker board properly. But also, getting 4GBs of ram Stable on this board is an issue, and the only accounts i've heard of it working were at 800mghz or less, i havnt heard of any one getting stable at 1066. Its the mem controler, being to heavily burdened. Most people tend just to get 2GB of fast Ram, some people go for 800mghz and extremely tight timings, which is easy to achive on this board, or you can get high clocks from your ram by loosening them. But either way, anyone who wants to serious overclock the board will have far more success by watercooling the northbridge and sticking decent risers or heatsinks on the pwm chips, and just a simple active HS on the southbridge. I used swiftech mcw30 on northbridge, and Thermalright HR 09u riser on pwm chipsleft of CPU, still have stock cooling on the top PWMs and southbridge, but i might change that.
