CPU and NB skews are very sensitive so it wasn't hard for me to find the optimal skew settings. i found that delay 200 and delay 100 was the best and anything different than this would either not post higher than 485fsb or crashes right away. i'm pretty sure it's not the skews but i'll try playing with this again. i have not touched my memory settings, so could i get some help on this? i think that's what's limiting the last reach for 500fsb.
