1st time OCing E8500 (C0), Rampage Formula

3600MHz (400x9)
BIOS: 1.3v (1.264v idle XP, 1.24v load)
DRAM: 1.96v (800MHz 5-5-5-15 2T)
NB: 1.43v

53c under load. (2 instances of Prime95)
Cooler: Xigmatek HDT-S1283

I should prolly change the other voltages too?
CPU PLL Voltage ?
FSB Termination Voltage ?
South Bridge Voltage ?
SB 1.5V Voltage (1.5v probably?)
Loadline Calibration ?
CPU GTL Voltage Reference ?
NB GTL Voltage Reference ?
DRAM Controller Voltages ?

With an FSB of only 400 MHz and 2 x 2GB of RAM, you don't need to be pushing 1.43v through the NB. Drop the vNB to no more than 1.3v, leave CPU PLL Voltage at it's default of 1.5 - 1.55v, leave FSB Term. Voltage (VTT) at the default of 1.10v, leave GTL Ref. Voltages at defaults of 0.63x and 0.67x, etc... basically leave all the voltages at default w/ an FSB of 400 and a mult. of 9.0, except for maybe the Vcore. Run Prime at your current settings, and check for stability.

53c under load. 1.25vCore (BIOS), 1.31vNB rest default.
Stabile 7 hours orthos Small FFT.
3600MHz.

Starting to push it closer to the magical 4GHz.

just set it too 8x500 with 1:1 divider for now...

You shouldnt have to mess with any voltage settings running at 4G...I can run 4G on default voltage with my E0

When I read thinks like this I feel sad for all the people in the world who don't even know what overclocking is. They have a potential 30% increase in performance without doing anything but changing the fsb. Wow.

I'll go 4GHz tomorrow.
glock19owner - My E8500 is C0

425x9 (3825MHz) 1.25v
56-57c under load with doors and windows closed in a pretty small room.
~5 hours orthos stable.
