I've just helped two people build quad core PC's based around the Q6600 chipset.
The spec is Antec 900 case, Hiper 630w PSU, Q6600, 4gig RAM (2x2gig), Asus P5Q Pro (Intel P45 chipset), Tuniq Tower 120 cooler all from OCUK.

I've got quite a bit of experience with Q6600 overclocking. My previous builds have all hit 3.6, 3.5 and 3.4 respectively, and I've never seen one do less than 3.1gig at stock volts until now.
These latest Q6600's won't do anything more than 3Gig. I tried extra voltage on CPU and mobo areas, all sorts and nothing gets them stable above 3050Mhz

Really disappointing results! It looks like the glory days of Q6600 overclocking are over unless the current stock are just bad examples :(
 
I'm not sure, I was wondering if they're not making new ones and we're just seeing the last ones now.

I'd tell you the default voltage, but the Asus board is annoying and either sets the voltage for you on 'Auto' or manually from a list. When you choose manual, rather than choosing the default VID as a starting point, it chooses the lowest on the list and you have to select your own voltage.
 
Just out of interest where did you get your Q6600 from? Was it from OCUK? Mine have been ordered by my work elsewhere so it'll be interesting to see what arrives in terms of VID, last 1 they ordered which is in my system had a VID of 1.2625 and I've got it running at 3.2Ghz with a BIOS vCore of 1.31v.

Mine was purchased from oc about 2 months ago. Full retail package, 1.2750 vid, batch code **03A746. Around the time i got mine a lot of people seemed to be getting ones with the higher 1.325 vid.

first 2 digits in batch code shold be the letter L and number 8 (text speak filter at its work)

Mine is also from the 03A746 batch (bought 2months ago). I was a lucky one and got a 1.25VID. I wonder if the 1.325 ones are from a different batch?
 
Agreed - got a Q6600 G0 a few weeks ago - VID of 1.3250, needs 1.4v to get 3.2ghz, and a ton more (1.56v) to get 3.6ghz stable. I have booted at 3.8ghz and 4ghz but it wasn't stable for any length of time in prime or occt,

Still - happy with that as it makes a hell of a system. Not going to lose any sleep over the 400mhz I might have got with a different chip and as it is, that's exactly where my E6600 topped out at :-)
 
Bought one a couple of weeks ago VID 1.300 - BIOS bootable at 5gig on water - but its on a crud 650i board so it won't hold settings over 3.3gig :( planning to put it on the P35 - but that won't supply more than 1.57v actual which won't get much above 3.8-4.2gig.
 
I also got one a few weeks ago, with the batch number **07A369, which has a VID of 1.325. However, it will happily reach 3 ghz well under stock volts, and sits at 3.3 ghz at a shade over 1.35v. Im probably quite lucky to have got a fairly decent one (over at XS, the 807 batch is considered to be quite good), but im not sure the VID really counts for anything.

As for the OPs original statement, i have been using mine with the p5q deluxe. Out of the box, overclocking was pretty much a no go - i just couldnt get it stable without much higher voltages, and im not sure i even made it past 3 ghz. However, bios updates helped no end - perhaps trying to update the bios to a more recent version may solve you clocking woes!
 
Has anyone got a decent list of the batch numbers and associated vid / OC performance. I know there is w33bo's list but im looking for something more definitive.
 
@jaxon

Seems reasonable - some chips need more volts than others, and its also dependent on other aspects of your setup, particularly the motherboard. I think that a lot of the more seasoned overclockers on the web would say that you will be fine putting 1.5v through it provided the temps are okay. I have shot 1.5 through mine, but personally wouldnt want to do so for 24/7 usage, as it gets a little toasty for my liking, and to be honest, i havent found much that the 3.3 ghz clock wont handle.

EDIT: Actually, the overclockers guaranteed ones state that you may need to put up to 1.5v through to get it stable, and i seem to remember the 'guaranteed to run at 3 ghz' option said that it may need 1.4-145 for stability, so in this respect, your doing pretty well.
 
Well i bought mine a few months back ese where with a 1.325 vid and i can get it 3.4ghz stable at 1.5v (windows) but can't get it orthos stable at 3.5ghz.

In a couple of days my Abit Ip35 is going in so see what happens.

I have a funny feeling its not my board stopping me though.
