OK,so here's the dilemma. The cpu runs Orthos for more than 4 hours on small FFTs. The RAM passes memtest 86 v.2.0 at the current setting. Orthos fails at 37 minutes under blend test. With each bump in DDR2 voltage Orthos fails a little sooner. I went all the way p to 2.274v for the RAM and failed blend test in 9 minutes.

Here are some voltages I am not all that familiar with.

CPU VTT = 1.13
MCH = 1.52
ICH = 1.09
ICH IO = 1.50
DDR2 REF = 0% (options are: +2%...0%...-2%...-4%)
CPU GTLREF 0%2 = 68%
CPU GT:REF 1&3 = 68%

Maybe changing one of these will help my blend Orthos stability?

Thanks -Jim
try 63-67% for CPU GTLREF...i read that the 45nm cpu's are designed to work at 63% for stock voltages...so...work from there up to 67% or 68%.
