*Official Retail G0 Q6600 Overclocking Thread*

[hausner]

Anyone got Q6600 G0 L723a891 ? What is your oc result?

[Gnarr]

How do I determine wether it's a G0 stepping by looking at the package? Is it just that all Q6600 made after week 22 are G0's, or is there something else?

What is the "slacr" is it a part of the batch numbers on the chip itself?

sorry for the noobish questions..

man after looking at the latest replies in this tread, im REALLY confused as to why my temps are so high on water....



i think i may have posted this earlier in the thread too, but im seeing guys doing super high volts and maintaining better temps than me and im only doing 1.4v

im on petra's elite kit (Fuzion Block, MCR220, DDC3.2 w/ petra's top

a picture of my setup:


its my first time doing a WC loop, did i do something wrong?? the fans are on push, and my powersupply actually sits on the other side of the rad.

Yeah, something is wrong there. I'm runnung the same OC (400x9 @1.4v Real) on my Q66 G0 and it hits 59c (Core Temp 0.95) in Prime95 on Air with a U120-X.

Are you sure you applied your TIM?

Is it the same story that the lower VID, the higher temp compared with a higher VID chip at the same clock?

im not really sure, i mean, it technically makes sense as less vid means more amperage to put out the same power, and amps are what give off more heat than volts...but is it really that much of a difference?

anyone with the lower VID chips shed some light on this?

Is this to say that chips with lower VID will be hotter when the voltage is raised to the equivalent of a higher VID chip?

Very strange indeed!
Makes an interesting situation do you aim for a lower of higher VID chip if this is the case!?

Just go a Q6600 G0, vid value is 1.3000v.

Doing 9 x 400 = 3.6GHz with 1.4v real and prime load temps don't break 50C.

Looks like the lower vid value chips are deffinately running hotter at the same vcore as higher vid value chips.

what kind of cooling do ya have

this is gunna really suck if you say something like "air" lol

Water, D-Tek Fuzion + 8800 Ultra highly overclocked in the loop as well. Ambient temps were 27C when I was getting 50C on the cpu @ load.

[xgodxicex]

hrm, i wonder if i will get better temps by having my fans pull the air isntead of push....if you look at the pic, right behind the rad is my power supply....right now my fans are sucking in ambient air from outside of the case and pushing it through....i wonder if the air is jamming between the radiator and the power supply (only half of the radiator is blocked by the psu)

[fallwind]

Just got my G0 too, L724A639, vid is 1.2625v. Max Prime stable on water is 3.6GHz 1.45v as set in BIOS, MB is a P5K Deluxe. Temps are just horrible, reaching 70c with small FFT! I reseated the CPU block (Fuzion), even took it apart to see if anything was restricting flow with no joy. It's a disappointment because that's the exact same OC I can get out of my QX6700 B3, same temps too. Atleast the P5K didn't fail to impress, 450x8 no problem at all, RAM running at 1125MHz. My old P5B couldn't even come close to that.

[xgodxicex]

yea man it really is dissapointing (and reassuring for me that its not my loop that has the problems), my temps are exactly the same

SLACR is the last 5 digits in PROD CODE: of the retail box.
If you see that it's a G0

@TinTin,
I have a VID of 1.25, and running with a Higher vCore, but w/ a little Better WCing setup than yours, it runs pretty warm, according to me.

Find my post in the last few pages, to see them.. 51-51-47-47 @ 3.6Ghz @ 1.40vCore, if I remember them correctly.
Specs in Sig.

[NJDevilsFan21]

I think I've got a 4GHz capable chip... Maximum voltage my motherboard could supply is about 1.45V under load from 1.59375V set in the bios.

Anyway, here's 3.6GHz - not test for hours, but it is a good indicator that my settings are close to stable.



I also tested out 3.8GHz, with that maximum my motherboard could supply. Got about 5 minutes in... and something started to smell like it was burning coming from my computer . Everything seems fine, it could have been the little rubber straps attached to the Ultra120x, at least I hope it was those, as the CPU chip was 69-74C under load at 3.8GHz...

By the way I cheated on the ambients because I had the ambient down to 68F from 80F, so I'm not realistically looking at these kind of overclocks until... October. But right now 3.6GHz is definitely looking like my winter overclock. Maybe even more depending on what the ambient room temperature is.

By the way, batch: L723A841

[strange|ife]

A batch are better thats all i know, i had a B batch and it was terrible, barely would do 3.4 played with it for a week.I could post at 3.6, even with 1.65 set in bios, orthos would fail. I sent the sucker back and bit the restocking fee bullet, why keep something your not happy with.?!?!

seems B batch is donkey balls. A guy i worked with just picked himself up a G0 aswell, of course it was a B batch, he hates it. IT actually doesnt clock aswell as his B3, it does run cooler though @ 3.1 he couldnt get it past 3.2

Ive got my old e6600 back in and sitting at 3.75 as i type this, waiting on my RMA/refund

What does it mean if my OC is Prime stable for 12hrs+ but crashes when I try SuperPi 32M? Is that RAM related?

Nothing!

My overclock is stable when none of the applications I actually use don't crash!

Most likely its your ram or northbridge.

so does coretemp 0.95 read G0 quadcore temperatures correctly?

seems like it, yes.
