Hi Mishtar..welcome to HWC.
I'm gonna rattle off what works best for me.
-E8400 C0 ..(TRUE 120)
-2x1GB Ballistix 8500
-Many HDDs..OS-XP Pro(32)SP2
Very similar setups.
I'm sure you know how to get the fun settings..ALT-F1..
Try these settings...if you feel comfortable with them:
Robust Graphics Booster - Auto (basically overclocks GPU..causing instable CPU O/C)
CPU Host Clock Control - Enable
PCIe Frequency -10
MHz don't use Auto... 101, and sometimes 104 work best.
C.1.A.2 - Disable
Performance Enhance -Standard(this messes with Perfomance Level setting in RAM if enabled..can ruin O/C)
System Memory Multi - Use
(gives 1:1-666MHz).....2.40 gives 6:5-800MHz....etc.etc.
DRAM Timing Selectable - 4-4-4-12
Advanced Timing Control - Leave all at
System Voltage Control - Manual
DDR2 Overvoltage Control - +.4v..remember..this is on top of JEDEC standard which is 1.8v... so +.4v = 2.2v
PCIe Overvoltage Control - +.2v
FSB Overvoltage Control - +.3v
(G)MCH Overvoltage Control - +.3v
CPU Voltage Control - 1.400v(DS3L shows vDroop/vDrop of ~ .06-.07 which leaves 1.33v-1.34v under load)
In Advanced BIOS Features section:
No-Execute Memory Protect - Enable
CPU Enhanced Halt(C1E) - Disable
CPU EIST Function - Disable
Virtualization Technology - Disable...unless you're gonna be running VMs.
CPU Thermal Monitor 2(TM2)- Disable ...i disable as much as i can get away with.. never had a problem with all these settings in 9 months.
In Standard CMOS Features section:
Halt On - No Errors
I agree with ElDonko about starting @ 1.400 vCore...you can always back it down.. or
may even have to raise it a touch higher. For 24/7 running, i wouldn't go over 1.45v (many will say 1.40 and even 1.35v)...good cooling plays a role in this.
** Perform these mods/settings at your own risk** I'm not responsible if things should go south.
GL, have fun, and let us know how you make out.
Edit: Flash to most recent BIOS.. still F8f as far as i know.
