I did not make an attempt to make the system stable at 4Ghz, but I browsed the web for 40 min before I manually rebooted and down clocked. However, at one point when I first got it working at 4Ghz I tried prime 95 and my system froze instantly. You're right that auto overvolts. I've...

you're right that my FSB voltage is a bit high, but I think I needed to up that in order to get my NB reference voltage multiplier to work out. I believe Vfsb * NBref = perceived Vfsb voltage or something like that. so to get a perceived nominal Vfsb of 1.2 with a multiplier of 0.67x...

I agree. From my experience, Vcore doesn't play a very important role in OCing to 4ghz. It's all about NB voltage, FSB voltage, and NB GTL reference voltage. you can see my post about it here http://forums.anandtech.com/me...=2174531&enterthread=y

Here are a few more reference voltages numbers Everything set to auto (2.66ghz, 8x333, mem@400mhz ): Vcore = 1.18 FSBT = 1.20 NB = 1.36 everything auto except FSB @ 400 (mem @400mhz) Vcore = 1.22 FSBT = 1.33 NB = 1.63 mem @ 500mhz Vcore = 1.22 FSBT = 1.34 NB = 1.63 So my...

The other q9450 thread seems to have gotten kind of cluttered, so here's my try at 4ghz. I haven't kept up with all of the latest overclocking bios settings so it took me a few hours to achieve this speed. I'm not going to run at this speed, but I just wanted to see if I could get there...
