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:

@evilroot - damn dude, that's a lot of PCs! Have you noticed that your 1.2875 VID chips run @ a lower voltage when overclocked than your 1.3215 or 1.3250 chips do? Have you ever compared them in a pseudo-scientific fashion?

Still working on maximum prime95-largeinplacefft-stable stock voltage overclocks.

1.325 chip is definitely scorching hot compared to the 1.2875V ones. Haven't pushed the chips to the limit yet though (they're not mine, they're for my department's cluster... hence only stock voltage overclocks). I have played around with the 1.3125 and 1.325V chips and the temperature difference is startling. One other thing to note is that TAT/CoreTemp report a larger delta between the two core pairs on the 1.325V (T1-T2=5C) chip vs the 1.3125V (T1-T2=3C) chip. I won't claim that it is a trend, but that is quite interesting.

i have G0 stepping
VID 1.265

Reply to kenjix217

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?

The 1.2875V chips *definitely* can run at a lower voltage at stock and overclocked. They also OC better than the 1.325V chip.

The VID that is given by CoreTemp is the voltage that Intel binned your processor at and what your motherboard will provide to the chip if you don't tell it to use a different voltage; I speculate that Intel tests the stability of the CPU with decreasing voltage at some constant clock speed until the CPU fails, then adds in a safety margin on top of the lowest stable voltage.

(More speculation) Therefore, a CPU with a lower VID should be able to overclock better than one with a higher VID because it can operate stably at some speed at or above stock speed at a lower voltage.

So your best bet to get an overclocking monster would be to buy 6-8 G0 Q6600s, and then pick the one with the lowest VID.

Every time i try to load core temp it says driver failed to load...and then pop ups of the same thing happen over and over again until i go to the task manager and stop it. Does coretemp work with vista 64 bit? Anyone else have this problem?

Already tried to load that one too. It says driver couldnt be found or something like that. I guess i dont get to see my vid until they release some drivers for vista 64bit. Is there anyway to check it in the bios or something?

In Core Temp 0.94 I have a B3 Q6600 with a VID of 1.3250V

I could have sworn in 0.95 it said VID 1.1625

However, 0.95 crashed my system once so I downgraded.

1.275VID for my new Q6600 G0... unfortunately, I can't get it to run 3GHz at stock voltage. Scythe Ninja in push-pull configuration.

EDIT: Couldn't get 3GHz at 1.35V - instant BSOD upon entering windows. Seems like I'm far from stability.

EDIT: Max clock of 2.80 GHz found at 1.200V (1.136V CPU-Z), 2.9GHz at 1.275V (1.200 CPU-Z), 2.955GHz at 1.35V and *1.425V* (1.272, *1.344* CPU-Z). This chip refuses to run stably over 2.955GHz no matter what I do to it. Suggestions?

evilr00t you may have just been unlucky, or it may be your motherboard or power supply, although I doubt the latter.

Identified the problem.
I left speedstep on so I decided to lock it at 8x instead of 9x using RMClock. Then, I bumped the FSB to 330MHz for a final clockspeed of 2640MHz. Prime95 fails within seconds. Definitely a FSB wall at ~325MHz.

Final overclock: 2926MHz (9x325.09) at 1.250V (1.184V fullyloaded CPU-Z). FSB wall is at 325MHz. This overclock is Prime95 stable 4 hours and 30 minutes.

G0 revision here. CoreTemp95 VID = 1.3125v

I'm @ 3Ghz 24-hour stable @ 1.275v.

That's good, right? No? Hmm?

Reply to krazynutz

You can add one more GO

VID 1.3250 from coretemp at stock speeds.

I wonder if my GO step will have any benefit over the worst B3s?

Reply to joemccarron

You know my frequency is 400.91x6.0 instead of 266x9. I don't know what I'm doing I just put the processor in and booted.

Reply to joemccarron

Update your Mobo's BIOS. You might need to for it to see it correctly.

Reply to krazynutz

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.

Hi i got a asus rampage formula with a q6600 VID 1.3250 in core temp;
Does this mean my oc posibilities are low even with good cooling?

Reply to cats_paw

I have a G0 model with a vid of 1.215.

@cats_paw

Your VID isn't the only important factor in your chip's overclocking ability. A lot of it depends on your motherboard, memory etc... There IS a trend, however, where lower VID chips tend to have overclocks with lower voltages. This isn't always the case, however, because there have been quite a few chips that don't oc well with great VIDs. Generally the common benefit you see in low vid ocing are lower temps since you don't have to bump your vcore up as much as others do. If you have a stubborn chip, you have a stubborn chip. regardless of vid...

The only way to find out is to try yourself.

I have a G0 model with a vid of 1.2625 volts. Until I saw that chart, I thought I had a relatively low VID. Mine will run at 2.4 GHz. at 1.225 volts. Reached 3.6 GHz. at 1.425 volts (drooping to 1.40 volts) with a TRUE/S-Flex SFF21F in an Antec 900 case with all case fans set to LOW. P95 stable after 72 hours. Temps reach 61 C to 65 C.

cats_paw, all you can do is try.
