As soon as I adjust NB and RAM voltages, I'm again rock stable at boot/bios load.

Guess, every system has its specifics The most important to consider, is that it's hard to 100% be sure ofan OC, it needs time...
Thanks. The only way I got mine stabe (despite inc NB volts and DRAM volts) was to change strap to 333 and hence DRAM speed from 1103 to 1057 - memory rated at 1066. Seems to be OK now on specs about 5 posts above.

I am interested in your thoughts on NB voltage. I can get to 440 FSB with 1.4 but any higher needs 1.55. I notice you get 475 at 1.25 but use aftermarket coolers - is there any voltage you would tweak to allow 450+ at 1.4 (I have tried most with no success).
