That's interesting, I think I noticed the same on my Q6600 and P5Q-e. BTW what's the highest fsb you can get on your chip? I seem to be able to only get 380x9 (G0 stepping, 1.300V VID). I tried lower multipliers but can't seem to go above 380 fsb.Originally Posted by NBF
400 strap don't work with Q6600. It results in no boot or boot very unstable.
It's been like this in all BIOSes I tested, but it doesn't make much difference, 266 and 333 straps are better anyhow and fully stable.
This chip is a Q6600 L745A (VID 1.325)
Highest is 516

I think your chip can do better than that.
Hmmm well I never went down to the 6x multiplier. I guess high fsb trumps high clock speed in all cases? Please post your bios settings, also which bios are you using? Oh ya and I have 2x2gb PC2-8000 (OCZ Platinum XTC), but one of my sticks is bad so I have to get it RMA'd.This chip is a Q6600 L745A (VID 1.325)

I have same fsb with 803 and 1102 BIOSes

Wow 1.5V for VCore, are you on water cooling? Forgot to mention that I'm on air cooling, I have an OCZ Vendetta 2 using OCZ Freeze TIM. And I thought you were on 516x6, are you more stable at 500x7? I didn't think the quad Kents could go that high.
I was just trying out the board, I run 450x8 or 400x9 depending on which RAM kit is on the rig.
Yes, 1,5Vcore for 3600... this Q6600 is the worst I've had
I was hoping to get lower PL
That kind of Volts is totally unnecessary
What is your cooling setup and how are your temps?Yes, 1,5Vcore for 3600... this Q6600 is the worst I've had
NBF, I'm trying your settings with my Q6600 (G0) and P5Q-E (1101 beta bios). I found I couldn't boot into Vista 64 without keeping VCore and NBCore close to 1.50 V like you. However my system isn't Prime95 stable, keeps freezing after a couple minutes, so I'm progressively dialing down my FSB frequency. I'm down to 494x7 right now, but my temps are hovering around 71-72°C. I think that's the max recommended temp for my chip according to Intel. Should I be worried at all?
This chips are pretty hard to clock fsb and they are not equal, some will do higher. I think you may be close to stable now.
Trust RealTemp, it's a very well made software, it's as close as a software can get from the real temperature. I personally don't worry with anything below 70°C Prime full load.
Thanks, RealTemp does seem like a great program so I'll make the switch over to that. I feel better seeing temps around 66-67°C, just makes me "feel" safer.I think my Q6600 can do 490x7 but I gave up on testing. Instead I wanted to try 444x8 so I could run my ram at its rated DDR2-1066 speeds (it was at DDR2-980 at 490x7). I changed all voltages to auto except VDimm=2.0V and NBCore=1.5V. So now my VCore is 1.44V on auto, makes me feel safer cause 1.50V for VCore was scaring me a little...
