Q6600 owners... what is your VID?

[graysky]

If you own a Q6600, please reply with your VID and the stepping of your chip. The VID can be found using coretemp. If you're using vista, coretemp will not display the stepping in some cases, so you can use CPU-Z (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:

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.

Questions:

-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?

My first G0 had 1.3250V

[graysky]

so you've had 2:

1.3250 and 1.2625

Can you comment on how each overclocked and @ what voltage?

The one in the photo was running 3.0 with with 1.20v after vdroop, I believe I had it set at 1.25 in the bios.

The first one ran 3.0 1.27 in the bios, 1.22 after vdroop.

Never had the opportunity other than a real quick oc due to my board being shot, the rma will be here on 8/13 and a P35 on the 15th, so then I can get some numbers.

I can't run any faster the 1600 mhz on my cpu now, or it won't boot....as mentioned above, the boards shot, and I had these severe issues with both G0's, my B3 was just fine.

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.
