Really? What's your FSB and ram at when the 400 strap won't work? Also what's your vNB?

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.

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.

This chip is a Q6600 L745A (VID 1.325)

Highest is 516

4 core benchable 500fsb



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.

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

1.5v on the northbridge for 500fsb!???

I was hoping to get lower PL

That kind of Volts is totally unnecessary

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.

That is the exact same thing that happens to my Q6700! About 1 month ago I tried 400fsb strap and no boot at all. In fact I had to clear my CMOS because I couldn't restart or anything, and then when I did get CMOS cleared and settign restored minus the strap I was no longer stable at my previous setttings so I think I screwed something up somehow, I will never use 400strap again out of fear.

I'm confused on one thing about this northbridge strap business. When you set it on Auto, doesn't it sometimes switch to 400 automatically then?

no, never.

[wongnog]

no, never.

So what is the nothbridge strap set to when you put it on auto?

[ThugsRook]

So what is the nothbridge strap set to when you put it on auto?

it would depend on the fsb and if youre setting the ddr speed manually or not.
but generally it will set nbs333.

when it comes to any of these P5Q boards, you really wanna keep anything in the bios away from being set to auto.

Hi,

I've had a similar problem too.
It seems this mobo (or more likely a buggy BIOS) doesn't like the strap to be manually selected.
If I leave the strap setting on AUTO and select a memory frequency that uses the 400 strap I don't have any problem though.
When I forced the 400 strap my PC refused to boot.

IMHO the P5Q Deluxe BIOS still has a LOT of room for improvement.
Let's hope the guys at ASUS are working hard...
