Here is a little more detailed analyses of the FSB hole on the Striker II Extreme with Intel Core 2 Duo E8400

All of the following will be ran at these configuration and settings;

ASUS Striker II Extreme nForce 790i Ultra
CellShock DDR3-1800
XFX 8600GT XXX Edition
WD RaptorX 10K RPM 150GB
Enermax PRO 82+ 625W
DD Torture Rack

Cooling;
CPU: Arctic Cooling Freezer Pro 7
Motherboard: original heatpipe cooler, reseated with MX-2

BIOS Settings;
CPU multiplier adjusted to maintain as close to 3Ghz as possible.
Memory set UNLINKED at 1800 8-7-6-21 1t P1&P2: AUTO
Voltage: CPU set at 1.35V in BIOS, 1.312 CPU-Z
Memory set at 1.9V
All other settings left on AUTO unless stated otherwise.




Upon loading Windows Vista 64, a memory benchmark is performed.
A short run of ORTHOS BLEND of around 10 minute is performed to establish preliminary stability.
A system files integrity check is performed after the ORTHOS run to check for file corruption.

FSB are checked in 25Mhz increments. Where one FSB works and the next setting does not, further FSB speeds are ran with settings in between to establish the starting point of the FSB hole.

Make from it what you will from these data.

I have tried using different memory settings away from 1800Mhz on FSB that weren't able to boot, but they don't seem to help... for example with FSB at 400, setting memory at 1866 still resulted in hanging at windows starting...
