very good work :), I'm trying to cool the membut i cannot find a suitable "active" cooler for mem, :( I really want to have a look how you make it. last night i tried 270*9, 1:1, 3600MB/s, and it hangs my system when I play chancast, an emulator for DC, It only hangs on a specific background, which requires full load of CPU floating point arithmetic, after entering that sence, it hangs after around 10s. when i switch back to 250*10, it works fine. I disabled pagefile on win xp, sp2. Tonite i will enable it and test again. but i think maybe we can try to use higher voltage on CPU and HyperTransport and northBridge, I checked a lot forums and find someone do some hard mod on MB to get 3.1V for mem. There are many settings one can tweak from hardware to software, we need to try them out:) following link shows a vtt mod for kv8pro http://www.xtremesystems.org/forums/showthread.php?s=&threadid=38946
