squeezing a bit more out my overclock

[233]

right spec is

Gigabyte P35 DS3R
Q9450
8gig (4x2gig) corsair x2x028 pc6400 ram
8800 gts
corsair TX 650 PSU

current settings
FSB 435
ram set at 2.0 divider, (lowest i have on the list)
mch +0.3v
FSB +0.1v
CPU at 1.325v
ram +0.2v

now i can post fine at speeds up FSB 475(8x multi ) 3.8ghz

but cant boot into windows with anything beyond 3.5 currently running prime stable in windows at 3479mhz on a 435 fsb, anything higher than this results in hanging during windows booting. if i run with 4 gig ram i can boot into windows and prime at 3.6 ghz quite happily

anyone care to advise on eeking a bit more out my system?
ideally want to try and get it running at 3.6ghz and above before my 6970 arrives

Running my Q9400 at 3.6

I was told NB and Vcore is key to a good clock increase on the 9*** series quads

Vcore 1.34
NB 1.5

Running my Q9400 at 3.6 also

In BIOS

CPU Voltage 1.25
NB Voltage 1.40
SB Voltage 1.20

iirc 9450's hit a wall around 3.8.

that's the most i could get mine to, and that was with about 1.4v core

 

[koooowweeee]

you will be able to clock higher with 2x2gb of ram (so give the other set to me )

most cpu's clock to around 4ghz. what are your temps now?
