I finally narrowed it down to the ram and tested each set in both dimms in Memtest x86, which all passed. With 4 dimms installed again, checking all gtl references and voltages the board would still instantly get Memtest errors.
Finally, i got fed up and flashed from 0602 to 1012 and now everything works smoothly so far. I wish i had performance numbers to post between the bios' but 0602 was just not stable.
Anyway some nice new things i noted in 1012 compared to the older bios is 400mhz strap on NB (333 was max before) and shown actual memory timings. The new layout of the bios options under Ai clock (was named Jumper Config before) are reworked and imo annoying, the older bios had all similar voltages togethor, ie. NB voltage and NB gtl reference were togethor, now they're apart.
This bios seems to boot a little bit faster but that could just be me.
I mainly posted this for people who may be having trouble and are on older bios', similar to my previous situation, with their P5K's and have tried everything and cannot get stability back from where they had it before. Of course i would only really recommend flashing as a last resort.
