View Full Version : Q6600 owners... what is your VID?

07-27-07, 06:19 PM
If you own a Q6600, please reply with your VID and the stepping of your chip. The VID can be found using coretemp (http://www.thecoolest.zerobrains.com/CoreTemp/CoreTemp.zip). If you're using vista, coretemp will not display the stepping in some cases, so you can use CPU-Z (http://www.cpuid.com/cpuz.php) (it's listed under "revision") to get the stepping.

Here is a shot of mine for reference:

If all else fails, look on the box your q6600 came in; the last 5 letters after the Q6600 in the production code will tell you the stepping. "SLACR" means it's a G0 while "SL9UM" means it's an older B3. Here an example shot taken by XtremeTiramisu to give you an idea:

So, I have a B3 w/ a VID of 1.2875v

EDIT: Here are the data as of 23-Sep-2007 at 7:30 AM based on people's replies to my VID thread here and elsewhere; just as a reminder, please do not post your VID from here on out as I won't be updating the data sets:

Just updated the first post of the thread with the data collected. Have a look!

Okay guys, just updated the first post of the thread to reflect the new replies... have a look!

I don't quite know what to make of this whole lower VID = higher o/c potential thing. My chip for example, is a B3 stepping Q6600 w/ a reported VID of 1.2875V (coretemp), yet I can run 9x266 (stock) which is stable to 2x orthos for over 8 hours (I stopped it after 8 hours) @ 1.1375V in the BIOS which is 1.040V in CPU-Z under load. I can also run 9x327 @ 1.2275V in the BIOS or 1.208V in CPU-Z under load or a full 9x333 @ 1.2625V in the BIOS or 1.232 V in CPU-Z.

My point is that all these vcore values are under the VID reported in coretemp. In my case, the VID reported in coretemp doesn't seem to mean anything given that I can run my system up to a 25 % o/c well under this voltage.


-What does the coretemp VID mean if anything?
-When comparing two identical stepping chips, does the one with the lower VID equate to anything meaningful?

@Rivas: dude, 1.735 isn't an option. You also neglected to state your chip stepping.

Updated the first post of the thread with the data collected (123 replies now) and added some histograms and basic statics to help visualize the data set.

08-12-07, 04:37 PM
my bad, that was from my old QX6700 for striker mobo

current voltage is 1.6125 in bios VID 1.3
FSB 400, stepping 7, revision B3

I can go 300mhz higher but I think thats about it, didnt try it yet.

Will post pics later including case and the cooling.
That program cant handle phase cooling the temperatures are all wrong.

Updated the first post of the thread with the data collected (182 replies now)... this has turned into a nice little thread :)

I'll post you my values when I get my machine installed. I bought all the components on Saturday, but haven't found the time yet to install it all because I'm moving as well.

Okay all, this will be the final update; please don't post new VID data.

I'm not totally sure the integrity of the data collected is that high. What I mean by that is I have read several reports of different reported VIDs for the same chip on different boards. I have also read about the VID changing based on the speedstep state and other factors.

I started this thread hoping to see some sort of correlation between VID magnitude and vcore @ a given o/c level. I have received mixed reports on this front as well. I think the bottom line is there isn't a correlation between VID and overclockibility.

Since you guys took the time to reply to the post, the least I can do is update the data for the last time:

Replies for B3: 102
Replies for G0: 158
Total replies: 260 (a great response!)

I updated the first post of the thread with the new histograms.

Thanks to all who replied.
