Q6600 owners... what is your VID?

[Hatman]

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?

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?

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.

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

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?

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.

I am not absolutely sure wheter this tread is still "living"...it started back in July 2007...but not spoil the party...I have q6600 G0 model with 1.25 VID
