Q6600 owners... what is your VID?

post #1 of 84
Thread Starter 
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:

I'm running Vista 64bit, so most of the info here isnt accurate. VID might be, dunno. I have a B3 as well.

Word to the wise, Core Temp 0.95 DOESN'T work with 64bit. You just get a cascade of driver failed to load windows.

Yeah works about the same for me with Vista X64.

Coretemp works fine for me in vista64 but I had to disable driver signing and then run coretemp as an administrator, otherwise i get the infinite popup errors..

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?

VID is the voltage identifier that CPU sent to MB VRM requesting necessary voltage. Assuming the VID reported in coretemp is correct~ lower VID should have higher OC potential when compare with higher VID.

Well, We have two Q6600 installed into two of our computers. One with VID 1.300 and the other with 1.315. The 1.300 can OC to 3.42Ghz with 1.45v (bios) but the one with 1.315 need bump the vcore to 1.525 to achieve 3.42Ghz

So... did I answered your question?

Here is a shot of mine:



You can find the stepping either using CPU-Z (it's listed under "revision") or by looking at the box the chip came in... here is a pic from xtremetiramism's box; see the last 5 letters after the Q6600? In his case they are "SLACR" which means it's a G0. My box says "SL9UM" which is the older B3 stepping.

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

EDIT: Here are the data as of 02-Aug at 2:30 PM based on people's replies to my VID thread here and elsewhere:

50 replies so far for B3 stepping Q6600s:

2 people had a VID of 1.1625V
1 person had a VID of 1.2125V
2 people had a VID of 1.2500V
2 people had a VID of 1.2625V
7 people had a VID of 1.2750V
8 people had a VID of 1.2875V
6 people had a VID of 1.3000V
1 person had a VID of 1.3100V
8 people had a VID of 1.3125V
13 people had a VID of 1.3250V

32 replies so far for G0 stepping Q6600s:

1 person had a VID of 1.1520V
2 people had a VID of 1.1625V
1 person had a VID of 1.2125V
1 person had a VID of 1.2250V
2 people had a VID of 1.2375V
4 people had a VID of 1.2500V
6 people had a VID of 1.2625V
3 people had a VID of 1.2750V
1 person had a VID of 1.2850V
4 people had a VID of 1.2875V
5 people had a VID of 1.3000V
2 people had a VID of 1.3125V
whats your ambient temp? PLEASEEEEEE people post ambient temp so we can actually compare properly, it matters alot

Agreed. Have a look at this thread. I have 7 different room temp values and their respective load temps.
