oooh quad
I was kind of disappointed that my 4th was unstable...
Dont really have the cash right now to get watercooling but am thinking about it for the future. I generally keep my mobo temp sensor at about 45 under load so I am guessing thats around 40 at the core. I could go lower but cant be bothered with the fan noise going all the time.
What watercooling system are you using? what temps do you get? I guess having the 4th increases it a fair bit...?
the mobo temp sensor at idel reads around 21, after a good stress test it reaches 32. im using a simple swiftech h20 220 watercooling setup, only cost me 30 odd quid off an auction site lol, seems to cope with everything thrown at it

Wow that really is low. Im even more jealous now!
dont forget real core temps are around 7-10 degrees higher than the reported temps. on another note, the swiftech h20 setup is great for an introduction to watercooling, works very well and if you can pick one up cheap a great addition, the radbox is a great idea as well so you can mount the radiator on the rear of the case if you dont have a case made for WC.

Do you mean higher than the mobo sensor or higher than the core sensor?
I have found that the temps on the core are generally 5-7 less than on the mobo.
The K10 platform (Phenom, Phenom 2, Athlon 2) core temp sensors are not accurate, the motherboard sensor is much closer to the real temp and that in itself is likely to be off (under) by a few degrees.
If you're measuring by the k10 sensor, then your processor is too hot. Hence the "I put more voltage (read: more waste heat) through it and it becomes more unstable"
I am going by the mobo sensor since the k10 ones are disabled by the core unlock. The mobo reads around 40 under load if I keep the fans running all the time, I have speed fan set to 45 so that the fans dont have to run all the time. This should still be far below the max temp of the cpu right?
Also the vcore thing is not quite a simple as that. Adding to vcore does make it less stable but if I add a LOT to it (ie above 1.5v) then it gets more stable. I am thinking that having it set to 'auto' is pushing the voltage higher than I thought and so when I 'raise' it I am actually forcing it to be lower. Not really sure though. Does that sound reasonable?
It is currently set to auto. I was manually raising it by changing it to manual and increasing it (I was assuming that the auto vcore was 1.325v but I now realise this assumption may be wrong).
I will post some screen shots of cpuz at idle and load when I get home.
Thanks for all the help guys.
