Hey Guys,

I'm not sure if i'm doing something wrong here but I recently got a Q6600 and it shows in coretemp as 1.3250 which as I understand it is not the best for overclocking. I managed to push it to 3.3 Ghz stable on Prime95 for 11Hrs so was happy with that.

I have now swapped CPUs with my father as he got his around a year ago and the VID shows on Coretemps on his PC of 1.6250v and he doesn't overclock so is fine with my one.

However when I go into coretemp on my PC it's shows the VID as 1.3250 ! i've been in vista and xp and still shows as the same.

I Have now lowered the voltage manually to 1.6250v running at stock it has very low temps and has passed 20Mins of prime at about 47Oc ( Considerably cooler than my original Q6600 )

So i'm rather confused about what the actul VID of this chip is and what I should expect from it. I'd ideally like to hit over 3.3.

Any Ideas ???

Thanks

Kev
 
If ti says 1.325 in Coretemp, then that's it, that's the VID. Your father may have a chip that has the same VID as your one. It isn't impossible...
 
Yeah I can accept that it is entirely possible that VID is the same but then why dose it show on his system in coretemp 1.6250V amd then why does it run on stock at thoses voltes when manually entered. If the VID is higher shouldn't it want to run at the voltage shown on coretemp. Please tell me if i'm getting this wrong as kidna new to all this ?

Thanks
 
Don't get too hung up on the vid. I had a Q6600 that had a vid of 1.3500v and that still did 3.8Ghz. Concentrate more on the voltage that the cpu actually needs to run at a given speed. 1.6250v is far too much by the way. Especially for stock speeds. Get it down before you fry it.
 
ha ha I've just noticed on my posts I wrote the vid down wrong. I ment 1.1625. Oh well I've messed about with it for an hour so and didn't like the temps when it got to 3.0 and tried out 3.3 nad just got hot and failed right away. Just stuck my one back in and it's running stable at 3.3 on 1.4V with about 66Oc after long prime test. I think i'll just stick with that. It's fast enough already. Fun playing about with it tho. Thanks for you help guys.
 
The 1.1625 is probably showing because he has Speedstep enabled, hence the speed of the processor is lowered when not needed, as is the voltage.

I noticed this in CoreTemp with my Q6600.

VID does not change, it's a static voltage which varies over different batches of the same chip.

Speedstep reduces the multiplier when the processor is idle/under very little stress.

The difference in voltage you are referring to is known as Vdroop and can occur when the processor is under stress.
 
Actually all Core 2's (that I know of at least) drop the voltage when under SpeedStep, otherwise the power savings would hardly be worth it. My Q6600 has a VID of 1.2v, but drops to 1.1v when idle.

Ah fair enough, I didn't realise that. Never keep speedstep enabled long enough to notice :P
