Overclocking a MSI P6N SLI Platinum with a Core 2 Duo E6420

These are my overclocking results with a MSI P6N SLI Platinum with a Core 2 Duo E6420 (and a XIGMATEK HDT-S1283 120mm Rifle CPU Cooler).

how to OC:
increment FSB. if that doesn’t work, increment voltage and try again. keep FSB 1:1 to MEM
in my case, FSB/2 = MEM
when done, prime95 blend test, prime95 small FFTs, intel burn test (very intense!)

BIOS settings:
1) cpu feature
execute bit support disabled
set limit CPUID disabled
c1e disabled press f4 in this menu

2) chipset feature
HPET disabled

3) cell menu
D.O.T. disabled
EIST disabled
system clock manual
voltages (see below)
advanced DRAM… 4-4-4-12tRAS-auto tRC-2T @ auto voltage (g.skills were auto’d at 2-3-3-8 @ 375mhz [although i put 4-3-3-8-auto(17)-auto(2t)-auto(1.9)?])
spread spectrum disable CPU
CPU ratio 8

before wall
FSB 1500
MEM 750
CPU 0.000 (stock)
NB 1.3v (+.05)
SB 1.5v (stock)
FSB VTT 0% (stock)

after wall
advanced DRAM… auto
FSB 1700
MEM 850
CPU +.750
NB +.2 1.45v
SB stock

how to flash:
Afud408.exe /P /B /C

GPU temp after 2 mins of ATI tool artifact test
default 513/792 77 (60 idle)
OC 600/900
625/1000 80c
650/1000 83c
675/1000 [fail?]

1 hour ati tool artifact is a good test

using ATI tool
find max core - freezes at 669
find max mem - freezes at 1156
