[QUOTE=greg.m;3797497]Well i found out the volts i can run stable/errorfree 8.5x485fsb @ 1213.
My system likes normal skews only. After many many combinations i realized that the most important setting was nbv. In the beginning i started with 1.51nbv and i got a lot of errors and lock ups. I thought it was fsbv, vcore or ramv. I played with skews but nothing. I raised nbv a little @ 1.53 and then @ 1.55 but i kept getting lock ups during memtest without giving any errors before.The reason i raised nbv so little was that @ 8.5x480(only 5mhz lower than 485) i needed 1.49 to have a stable system. I went up @ 1.61v and i run 70-80%memtest without errors before my system freezed again. Finally i managed to find the magic - almost skyhigh - nbv setting...and that is...1.65. after that i could lower vcore from 1.325 to 1.29... Now ill try to lower ramv and see how itll go.
