**Official e8400/e8500 Retail OC Thread

[nickless]

hi overclockers
on friday morning i got new E8400 batch Q807A552.but after installing
in p5k dlx wi/fi which gave 550FSB with E6850 it disappointed me.this
batch couldnot go over 500FSB.i tried all settings but no luck.with
this MB E8650 could not reach 4GHZ but 550FSB surprised.e8400 can
go 4GHZ 9*445 stayable and 500*8 unstayable.all setting are on auto except
mem volts. any body with MB and this batch any got any luck.
core temp 0.99.1 showing VID=1.2250v i think this is bad
Leeghoofd what you think about this batch why not giving 550FSB.
is this cpu is a problem with FSB on this p5k dlx MB.WTF

I'm with the same MB and E8500 Q807A253 cooling by SS. CPU has very strange behaviour on my system. I can run Prime for 2-3 hours at 9.5*500 @1.55v, 3D Mark Vantage allso, but when I start some game then - blue screen I also tried all settings including RAM timings and voltages but no luck.
This is my BIOS 0812 settings , if there is something wrong please tell me:
- Ratio CMOS Setting: 9.5
FSB Frequency: 500
PCI-E Frequency: 101
DRAM Frequency: DDR2 1000
DRAM Command Rate: 2T
DRAM Timing Control: Manual
CAS# Latency: 5
RAS# to CAS# Delay: 5
RAS# Precharge: 4
RAS# Activate to Precharge: 12
TWR: 3
TRFC: 40
TWTR: 6
TRRD: 3
TRTP: 3
DRAM Static Read Control: Enabled
Transaction Booster: Disabled (0)
CPU Voltage: 1.56V
CPU PLL Voltage: 1.60V
DRAM Voltage: 2.20V
Load line calibration: Enabled
Clock Over-Charging Mode: AUTO
FSB Termination Voltage: 1.3V
North Bridge Voltage: 1.55V (under water)
South Bridge Voltage: 1.20V
CPU Voltage Reference: 0.67
North Bridge Voltage Reference: 0.63V
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled

So after few days of attempts and irritation I've left the CPU on 9.5*475 @1.37v. Now is stable in games, but it's a shame with subzero cooling to get numbers like this
