q6600: lower VID = better?

[IAmATeaf]

my [email protected] using stock voltage of 1.2850v gets up to 60c in temps under snm using a freezer 7 cooler.
under prime small fft the hottest core peaks at 52c.

im guessing the lower the vid the better the clocks may be? i have a vid of 1.2850 so i guess the guys with a lower vid will either have lower temps or the potential to clock higher on the core.

That's a pretty good overclock at stock voltages. TBH after getting mine to 3.2 I sort of lost interest and have left it there for the time being. Might push it up a notch when I get bored at some stage.

What vcore do you require to get 3.9Ghz with your current Q6600 stable ?

HI,

What cooling are you using? Ive got my q6600 @ 3.65(ish) and my temps are around 60 running boinc on all four cores 24/7 under water (fusion and pa160). your temps seem to be around 10 degress less and im using less vcore.

who are you asking?

im using thermalright ultra 120 extreme with 2 yateloon fans push and pull

Im running a fuzion (w/ quad nozzle kit) & PA120.3, it was only about 10c ambient at the time.

But the stock power output for the lower VID cpu will obviously be lower. So this is all irrelevant. The power consumption between processors at the same voltage and frequency should be equal plus an error term (which should be distributed under a normal distribution). Unless, the error term is somehow related to the VID (some kind of selection bias destroying the assumption of a normal distribution), on average, power consumption will be identical.

Exactly what I was thinking, the formula that was posted is wrongly assuming that the VID actually means anything.

Its obvious the VID is gotten from chosing a few CPU cores from a batch and then tested to see how much volts they need for their given speed...

Which is why some people with crap VIDs are getting better clocks than people with good VIDs.

End of the day, its a the ONLY indicator of a good chip, so yes, it won't guarantee a good clock...

But have you got anything else to base your decision on without being able to see the chip or know its stepping etc?

No!

So...

Lower VID = Better

Its just a good indicator but if you've already got a chip that does 3.7Ghz+ you'd be a cretin for swapping it WHATEVER THE VID IS ON YOUR CHIP AND WHATEVER THE VID IS ON THE ONE YOU ARE CONSIDERING SWAPPING FOR

70C under prime95 is fine, it's pretty much the max. core temp you could sustain for long periods safe. But that's irrelevent as no commercial software would ever push your CPU that hard.

Mine is 33C idle, 69C Small FFT's, mainly due to me having a HUGE tempertaure difference between cores, you're looking at upto 12C difference between core 0 and core 2.

2nd pass encoding in X264 pushes it to similar levels to the small FFT test

My Q6600's vid is 1.2375 currently at 425 x 8, 3.4Ghz @ 1.3v in bios and 1.280v in cpuz.

Hold on there, just realised this thread is a total waste of time...

Your chip can't even do 3.9Ghz, you need to set 1.8v in the bios...and you actually booted from there on air?

Why you weren't honest in the first place is beyond me, if you want help try not being a, well I'd get banned for saying it...crikey!

I'm sure my chip could do 4Ghz also, but it won't be stable like yours!!!!!

Given this new info you didn't bother providing in your first post YOU SHOULD DEFINATELY SWAP BECAUSE YOUR CHIP WILL PROLLY BE DAMAGED BY THE STUPID VOLTAGE YOU PUT THROUGH THE THING!

I have already adressed the voltage half a page ago, please read up...

Just swap the chip if you havent already, and dont put more than 1.5 through the new chip.
