*Official Retail G0 Q6600 Overclocking Thread*

[ineedaname]

Could you tell us the exact batch you got? L737Bxxx, what's the xxx in your case? I trust it's a B and not A series right?

Batch: L737B062

Date: 10/31/07

BTW turns out the xeon is a G0 not a B3 and performs similar to the q6600.

I got a buddy who has a bunch of these xeons for sale but not 4 long.

So if it takes your L737B 1.33V to reach 3600MHz stable, then how much do you give it at 4GHz 2x Orthos stable? I would think about 1.53V right?

The reason I ask is because my L737B325 also needs 1.32V for 3.6GHz and 1.432V for 3.825GHz so was wondering how yours compares.

Look carefully, 1.33V is my XEON 3220. The xeon is a G0 Week 17A. I cannot get this xeon to do 4ghz because of temps.

I have another q6600 that can do 1.29V 3.6ghz. This cpu however can do 4ghz. I'm still trying to get it prime stable but it should be doable at around 1.45v

Right now the temps are quite high at 4ghz but a lapping should fix that problem since the cpu is concave and the tim needs to cure.

Your chips are nice, however, YOU DONT HAVE ANY VALID LONG TERM STABILITY TEST!

So therefore YOU CANT say your stable. Not 1 screenie has you posting a prime longer then 1 hour. All your primes show less then 1 hour stress testing.

I have a 37B and you need AT LEAST 1.375Vcore on it to hit PRIME95 longer then 2 hours. After 2 hours the chip will fail at that voltage.

PLEASE post a longer prime, at least 3 hours if you cant do the 7hour standard.


Otherwise i might as well bust out the 4.1ghz which last only 10 min...

My chip and cooling has the headroom:



Those are load temps BTW... NOT IDLE... And its WCG BIONIC.
And XS is always recruiting great quadcores to crunch for our team.

What do I need to get to 3.6Ghz without water cooling?

I tried by upping the vCore to 1.36v, but got errors from Prime95 after 10 minutes. Also, CPU was getting Hot, about 68C.

Hi Novak and happy first post
I have the same Batch as you and I need on my 680i board without Vdroop about 1.375v for 3.6 everything below want stay primestable.
Good Luck

You need whatever vcore and other tweaks it takes too get your CPU stable at 3.6(if it can do 3.6) Just cos other are achieving 3.6 it on lower than 1.4v doesnt mean your CPU will do it. I need 1.425v with PLL 1.6,FSB=1.4,NB-1.4 on a P5K premium. for prime stable and thats with good ballistix 8500 memory . I would start with upping the vcore and loosening the memory to 5,5,5,15 - if you get it stable then try tightening the memory. Better cooling than a Zalamsn 9500 would also be a good idea -e.g. 120 extreme or ultima-90(nice small profile) will give better performance.Try MX-2 paste - doesnt need to cure and good as AS5.

Thanks for all the replies.

I'll get a new CPU cooler and some MX-2 paste before I start tweaking.
I was going to buy a ZALMAN VF1000 cooler for the 8800GT but with the REV 2 BIOS upgrade it seems to be fine.
