I have a minor dilemma running Penryn on this board. I am not concerned about temps too much as I am in an unheated garage in NY in February and the ambient temp never rises over 15C.

Anyway a bit of system specs and then the annoying scenario I have encountered.

CPU: E8400
ES/Retail: Retail
Batch #: Q746A377
Ship/Packaging Date: Jan. 04, 2008
Voltage(s) (Stock/OC'ed): 1.112/1.285 set BIOS (CPU-Z 1.27 idle - 1.25 load)
Frequency(ies) (OC'ed): 400x8 (4.0)
Motherboard: Abit IP35 Pro
BIOS: 16.B09
Video Card: El Cheapo X300 PCI-E

_______
*Extra* Memory(ies) (Timing(s)): 2GB OCZ SLI ready PC2-8500 5-5-5-15 running 1:1
*Extra* Memory(ies) (Voltage(s)): 2.0v SPD rates 2.3v for full rated speed
*Extra* Third Party Cooling Solution: NY winter (Zalman 9700)
*Extra* Paste(s)/Compound(s)/Other(s): Ceramique

Ambient temps were a balmy 14C in my garage. Idle temps around 36C - 32C and load at 37C - 42C. Temps read by Core Temp. All runs done in open case w' 120mm fan blowing on NB.

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
