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:

You have a different version of coretemp than me, but it crashes my boxes. cpuz has the real vid, and it ranges depending on my bios. Where can you get that version 95.3 ? Link ?

 

[graysky]

@markfw: it's an internal release that's not available to the public. The VID is different from the vcore.

 

[Diogenes2]

Mine is 1.26

The VID is set at the factory .. It is supposed to be the startup vcore at default FSB..

It will vary from chip to chip..

It is usually reported in the BIOS as the default CPU voltage..

That's why sites like Newegg list the voltage as 1.100V-1.372V

I hear the G0 is supposed to be .9 - 1.35

P.S.

CPUZ does not report VID, it reports Vcc ( Vcore )

 

[firewolfsm]

Imagine getting a .9V Q6600. I wonder how many 3DMark benchers would pay a fortune for it.

Umm, no. The reason Newegg lists the voltages as 1.10-1.3725 is because the VID may be as high as 1.3725, but it is never as low as 1.10v. The 1.10v is the voltage that they all run at with EIST (Speedstep) and C1E enabled. <<Obviously, if you're right about the G0's, they run @ .9v, when Speedstep and C1E are enabled, which would be sweet.

Mine is 1.325V according to CoreTemp. But I had it running down to 1.056V for its stock frequency. (F3 stepping) I do believe that lower VID chips have a better chance at higher overclocking, lower voltages, or lower temps but just like the way they bin E6600 vs E6700, it's kinda crap shot when it comes to its accuracy. Stepping is, however, more reliable than VID. (still can be a crap shot)

P.S. GraySky: I love the linked site in your sig!

I don't think there is a Q6600 F3 stepping... is this a quad or dual?

 

[PCTC2]

@graysky, I think he meant his B3

My Q6600 B3 VID is 1.3000v

 

[graysky]

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

Q6600 G0 1.3 VID

So far, booted @ 3.8ghz with 1.53V or so.

Doing 3.7ghz right now with 1.5V (Bios) 1.43V (In Windows)


Thermalright Ultra 120, 30-40c Idle speed!

Same here!

 

[Diogenes2]

Just got my G0 up and running..

VID = 1.3

I'll add to the OC thread when I've had a chance to do some testing..
So far I'm testing at 3.4g - vcore at 1.3 and my temps are a little higher than my B3 at 3.2g & 1.26v ..
But I'll go into that more when I have had a chance to test some more ..

 

[krahulik]

I have SL9UM, 06F7 (stepping 7), TDP 105W --> rev.B3, VID= 1.3125 V

Pack Date 6/21/2007.

B3 lol. Sorry.

 

[graysky]

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

 

[graysky]

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?

[swtethan]

Mine is 1.22v

"-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?"

The VID means that Intel certified the chip to run at stock (2.4GHz) at a certain voltage. When binning chips, they test voltages and decrease until they find that chip's potential. That means that one chip with a VID of 1.3 needs that much voltage to be completely stable, while one with a VID of 1.2 but an actual voltage of 1.3 will overclock higher.

It doesn't matter too much, but you can tell the difference between a 1.325 and a 1.2 pretty easily.
