*Official Retail G0 Q6600 Overclocking Thread*

No, 3.8GHz since that's what his screenshot is showing, not 3.6GHz.

1.392V for 3.8GHz just seems high for a very low VID Q6600. At 1.4GHz I would expect 3.9GHz if the yield is on par with the VID.

But you said

You have a very low VID Q6600 so I would say you could do it (3800) at 1.30V or less.

Ive not seen any 3.8Ghz under 1.3v without chiller/subzero.

If you have, i would like to see some links.

Anyone have a L738B233? I just got one going to put it together shortly...

[rbsmontemor]

Surely you don't need that much Vcore to get you to 3.8GHz???? You have a very low VID Q6600 so I would say you could do it at 1.30V or less.

Yes I need. And I think that's a very good chip...and run's @ 3800Mhz with less vcore than my friend's QX6850. 3600mhz @ 1.28v too

L738B233 VID 1.325v, not that good of a chip compared to my L734B164 with a VID of 1.2375.

Yes my mistake, by "do it". Somehow 3.6GHz locked into my head last night even though he's at 3.8GHz hence 1.392V seems much more reasonable, or very good actually.

It seems VID is a very good indicator of yield quality, but not the only one that determines the end result (overclockability etc.). I guess some silicon behaves different than others above a certain MHz speed hence why VID only helps up to level X (by using a low Vcore), but then the silicion chemical properties come into play.

I would think it helps having a low VID version chip. Couple this with a good yield and 4GHz at around 1.45V effective should be attainable, no? This could be done on air I reckon.

Wait, so you've seen under 1.3 with chiller/subzero? Shouldn't under 1.3 NOT require that level of cooling seeing as lower volts = lower temps?

Just got this L739B250 Date: 11/22/07

First tests:
4206MHz (9x467) SP1M
FSB 500MHz

Need more time to find best GTL's for high FSB.

Please also post your VID...

It's on the 1st screenshot (CoreTemp). 1.3000v

Ahh sorry, silly me. 1.744V seems about right then at the best of the crop could do it at around 1.6V given they do 3.6GHz at 1.27V-1.288V.

4233MHz (9x470MHz) SP1M
Yeah, VID is too high (1.3000V).

Yes. I think below 1.3V you can even on box cooler.

I haven't no, I was just trying to make the point that I think extreme cooling would be required to hit 3.8Ghz with under 1.3v. With extreme cooling you tend to need less vcore to get the same clocks as water/air.
