In case it might help someone - bios settings for rock stable 4GHz (8hrs Orthos Smal FFTs) on my E8500, 4x1GB Crucial Ballistix PC8000, bios 11/1, watercooled CPU/NB/SB/PWM/GPU.
See 8hrs Orthos Small FFTs session belowCode:CPU Feature Thermal Management Control >>> Disabled PPM (EIST) Mode >>> Disabled Limit CPUID MaxVal >>> Disabled CIE Function >>> Disabled Execute Disable Bit >>> Enabled Virtualization Technology >>> Enabled Core Multi-Processing >>> Enabled DRAM Timing Enhance Data transmitting >>> Fast Enhance Addressing >>> Fast T2 Dispatch >>> Disabled Clock Setting Fine Delay Ch1 Clock Crossing Settting >>> More Aggresive Ch2 Clock Crossing Settting >>> More Aggresive Ch1Ch2 CommonClock Setting >>> More Aggresive other subtimings >>> auto/current CAS Latency Time (tCL) >>> 5 RAS# to CAS# Delay (tRCD) >>> 5 RAS# Precharge (tRP) >>> 4 Precharge Delay (tRAS) >>> 9 All Precharge to Act >>> 4 REF to ACT Delay (tRFC) >>> 30 Performance Level >>.

One more word about memory performance... After "transforming" Windows XP from LanParty P35 to X38 setup without reinstall, memory performance looks like this... I think that system reinstall might help (a lot)... Although I do not care for every MB/s - try to focus on Voltages optimisation
Hope it helps someone
