L728A861

An old screen.
It's just 40min, it snapped after 80-90min's.
But it's stable for an ordinary use.



at 1.328v he's 2h QuadPrime stable, didn't go further then that.
I keep it at 1.344v just to be sure, no prob's at all for 5-6 months.

Oh, and the suicide shot is in the sig, it's with the old 965P board.

Sadly I haven't taken CPU-Z validation shots of either. The Q9450 can be done easily, tho it involves shutting down two Folding virtual machines so i can reboot. The Q6600 on the other-hand is currently running in another folding rig in a AB9 QuadGT, and there isn't a hope in hell of getting a 3.8ghz shot from it with that board (385mhz max FSB, tho it's running at 3.45ghz and only 1.28v under 100% Folding load).

On such overclock, and seeing your MB température, it must be cold there, no? Below 20°C for sure

[Cob]

Not quite.

I do overlook the North Atlantic, so an open window, cool sea breeze and a 40mm 3480rpm fan on the NB makes for decent temps.


This is the Q9450 currently under full Folding load at 8.04pm -

Yep, I can understand now those temperatures. In winter, with open window just for enough fresh air on my radiators, I reach same results. But, definately, 25-28°C MB temperature at 20-25°C ambiant is impossible on such overclock for a quadcore while folding or priming in large/blend mode. Expect rather 40-50°C depending on your setup, unless you WC the NB and RAM

[Cob]

You're assuming that the temp sensor is actually in the northbridge chip.

I may be wrong, but isn't it usually a sensor on the motherboard rather than in the northbridge chip?

[jonny_ftm]

It's somewhere between NB and Ram modules. Usually, on my tests, stressing RAM and NB is where the MB temperature increases. Prime95 small FFT quiet won't affect it at all

I was playing with my Q6600 this evening and got this...

Thermaltake BigWater 745 (yes I know, crappy water cooling kit)
1.625 bios set, 1.6 idle, 1.617 load

your cpu will die soon if you didnt knwo that. the max (limit) volts for it is 1.35

Nobody's cpu is going to die, relax. You can look at processor specs here. I myself think that 1.5v rating is a bit conservative as long as temps are kept at reasonable levels.

[Loser777]

The P45 boards are always a plus because many of them can do up to 500FSB with no NB voltage adjustment.

Really??? Been running mine @ 1.45v for quite some time now.... chuggin along just fine. It's 'rated' for 1.35v max. Keep in mind Intel probably set that at a very conservative level to keep the temps and the RMA's down.

[Loser777]

Stop spreading FUD. Most of the people here volt their Q6600s WAY above that 24/7.
1.45v is peachy unless u get crazy temps.

[psyxeon]

CraptacularOne will you add vid and temps to the topic? So we can see how many volts a high vid needs.

Fx: mine (vid-1.325) needs over 1.5 to go from 3.6 to 3.7
My tems are cool on water

got my new 1.215 vid q6600 cpu 3hrs prime stable today at 4ghz
but at high vcore any help to get it stable at lower vcore would be great

my system

my min temp is 31/31/32/31
max temp prime 65/59/69/69
cant understand why my core2 is so much lower cpu and black have bee lapped

Can you guys post ALL your settings for 3.6GHz?
I'm having trouble stabilizing my rig...

Extremely jealous of all you guys with crazy quads... I got two 1.2125v VIDs that both need 1.384v for 3.6GHz and won't do 3.7GHz shy of 1.496v.

It's 1.3V , it's not completly stable but I'll work on that this weekend
