*Official Retail G0 Q6600 Overclocking Thread*

[grimREEFER]

I just received my q6600- I was afraid I was going to get one from the L8xx batch, and I did , but the price (online only-not honored in store) of $180 was too tempting.

The VID is 1.325 and the batch is L804. Granted I've only tried it on my 780i mobo (which I consider to be a flaky overclocker), but I'm not sure it will even hit 3.6 ghz. I've got it OCCT stable for a half hour so far at 3.15ghz (450x7), but that required 1.6125v vcore (bios)/1.56v (everest). I need to set the vcore to around 1.675v (bios)/1.62ish (everest) to reliably get into windows at 3.6ghz (either 400x9 or 450x8), but at this speed OCCT crashes within a minute.

I've tried the memory (2x2gb gskill 1066) both linked and unlinked (and usually underclocked), and used a range of GTL REF values, and it doesn't seem to make any difference. On this board, I don't think it is capable of 3.6ghz unless I'm willing to go over 1.7v vcore in the bios !

I'm considering returning it and seeing if I can find any locally from an L7xx batch.

i have the same batch as you, bought it for the same price from fry's too lol.

i can get it prime stable for days at 3.2ghz with a 1.45 vcore, but i get random restarts when i loop 3dmark06 still or play games, and that goes away when im at 3ghz@ 1.35v ( i like to stick to even numbers lol). anyone know what can possibly be causing that?

Yup, the latest batch are bad clockers. Mine also L80x with VID 1.325V. I can do 3.2Ghz at 1.3V stable. Anything higher than that requires much more voltage. 3.4Ghz requires at least 1.375V. Tried 1.45V at 3.6Ghz and Windows will crash after priming a few minutes.

Same here:

L801A876

VID 1.325v

Pack Date: 22/02/08

2L75072
7A1750

I can do 3GHz with 1.28v, 3.2GHz with 1.33v and 3.4GHz with 1.464v but even 3.41GHz or 3.42GHz are completely 100% no go. I've tried better cooling, more voltage, loose ram timings, different FSB/Ram straps, it all makes no difference. Even 3.4GHz reboots randomly but can still Prime for 12hours solid. Odd chips, real odd and real crappy...

I didn't get the same good price you guys did though, mine would have equalled about $280...
