Been reading around for a solution to this prob.. maybe you guys can help.

I can run Prime 95 "small FFT"/Memtest86+ for 12 hours each no errors. However, once I start up the blend test in p95 it fails everytime at fft length 896k or 50 minutes into the test. So I started messing around with volts/timings and it still failes at that 50 min mark or if I set it to custom for that fft length.

I know its not my cpu... so I figure its either the timings or voltages for NB/cpu PLL/FSB term volt.

Considering I have loosened the timings quite a bit and it still failes at the same point makes me think one of my voltages are off. Here is what I have tried so far.

NB- 1.59 to 1.63v
CPU PLL- 1.58 to 1.66v
FSB term- 1.3 to 1.54v (It used to fail after 1 min when set to 1.54 so I figure this at least helped me reach the 50 min mark.)

I have active cooling on my NB/SB/ddr (4x1 Muskin 8500 ddr 1199 in bios set at 2.28v, which is 2.32-2.34 in everest)

Temps on NB never raise above 46C
Temps on SB never raise above 37C

All my other settings I use were recommended by anandtech guide. Any ideas?
