*Official Retail G0 Q6600 Overclocking Thread*

[Demo]

and to add i need 1.335v to be stable under vista x64, XP only required 1.315 my default VID is 1.275..

Is it safe to run this chip at 1.415v ( idles about 1.395 or so )

Btw most of you guys are really getting super low temps, im getting like 62-65c on my 3.2Ghz at 1.248 loaded ( 1.335v bios ) im also using a lapped true 120ex w/ MX2 maybe its my mounting ?

The max safe vcore is 1.5v to 1.55v as long as ur temps stay safe.

Maybe its ur room temp?

Maybe its ur room temp?

1.55v is rated to last how many years provided the temps say under 70c, probably 4-5years?

my room temp is about 28-30c depending on the time of day, and goes higher during summer like 32-33c on afternoons

I don't know how many years it would last , its just what i'v read.

My room temp was about 35c today and my Q6600 @ 3.2GHz was idleing at 50C .

with room temps at 30C, my Q6600 load temps are about 65C, idles at 40.

Once I had a really un-OCable model. It needed 1.55V to be stable at 3.6

I think that the best processors have L728 - L737 FPO

mine takes about 1.48v for 3.6 stable, and wont do much more on air at least. but on the other hand will do at least 480mhz fsb with tight performance level without even breaking a sweat.

[Bootup05]

What coolers are you guys using for your chips?

I run a Freezer Pro 7, (Great for Duallies, Not so for quads)

Need around 1.45V for 3.6GHz, although it's still not fully stable. BSOD's in Vantage @ CPU Test 1.

If I got a better cooler how much headroom could I get? Enough to try for 1.48 / 1.5V maybe?

My G0 is a 1.2875 VID Chip, Running 3.5GHz right now @ 1.4375v.

Want more Seriously considering going water now.

Might go out tonight in the cold see what Volts I need for 3.6 truly stable.

If I wen't water i'm hoping for 3.8.

[mikeyakame]

Thermalright Ultra120 Extreme.
TDP of an overclocked Q6600 with 1.40v or more is pretty damn high! My current draw in A on full load at only 3.36ghz with 1.38v is over 110A, 170W or so.

[Loser777]

Xigmatek S1283... was $27 when I got it... best cooler for the money.

[fatguy1992]

I'm just a IFX-14 with a 3000rpm (133CFM) Scythe Ultra Kaze fan. Soon i'm getting a SS Phase unit .

[chew*]

I just decided to actually push mine after running it at 3.2 stock volts for a year. 3.2g @1.225 vid, 3.6 @ 1.325V, this is with an OCZ vindicator........ last 5 of batch is 80047. Passed prime for an hour then i shut it off wasn't impressed with temps ( heatsink isn't that great ), passed 3dmark 06 and i reinstalled windows without a hitch at this speed today due to borking it attaining a stable speed yesterday.

I have a true coming this week and a spare small HD that i will use to find stable settings. we shall see how far she goes.

[pyongmu]

I have been running my Q6600 on a GA-P35-DS3P for about a year, with best stable clock at 3.7G, best FSB 463 and 24/7 at 450x8. I recently switched the mobo to a GA-EP45-UD3P and man, what a difference!
I have reached 4.05G and 500FSB just playing and currently running 24x7 at 463x8. I highly recommend these P45 Gigabytes.

[Demo]

with room temps at 30C, my Q6600 load temps are about 65C, idles at 40.

Looks like its the same as mine



@pyongmu

Im waiting for that motherboard to be on stock at my local retail store, did you use load line calibration ?

Yes, I am using LLC. With the feature enabled, the vdrop is around .02V and no vdroop.

[KELL5]

Installed Windows7 a few days back......finally got round to playing yesterday.

Higher clocks than any other OS to date with only -4c air

Gonna tweak my memory now to get Pi down a touch.

From what I have gathered just skimming through temps, chips, vid, it appears the lower the vid the hotter they run but the less voltage needed to attain a high OC.

For instance vid on mine is 1.225 and does 3.2 with stock vid. With LLC enabled and real voltage set at 1.225 cpu-z reports 1.208, I only need 1.325v (cpu-z reports 1.308) for 3.6, and so on but my temps are peaking 80C with a scythe ninja knockoff.........I will have TRUE black 120 results tommorow or saturday. I don't think there is a max voltage per say because of Vid discrepencies, I would say that .2 over vid is safe for air 24/7 though.

Speaking of LLC, i noticed my Q6600 needs no less than 1.248v when prime loaded, since my default VID is 1.275 with LLC enabled do i still need to bump my voltages or can it stay stock ?

if its prime stable at stock voltages then leave it alone, mine is stock 1.225 vid undervolts to 1.208 LLC enabled and stable @ 3.2. Just make sure you run a bunch of 3d tests, crysis loops tend to fail easier for me than 3d06 when i'm just a tad unstable but prime stable. Here's what i have so far.

[officermartinez]

I run my Q6600 also at 3.6ghz 24/7 (450 x 8).. I do like to bench my setup at 4ghz (500 x 8).. The best FSB so far on my board has been 515.

Believe it or not, thermal dissipation is relative to work being done.

If one CPU running at 1.2V and the other say 1.3V but both producing identical amounts of throughput (work) then theoretically they should both be producing similar TDP (Watts consumed) and have roughly same temperature. The 1.2V CPU will be drawing more current while the 1.3V will be drawing voltage.

The lower VID chip might be slightly better quality is all. But Mhz for MHz TDP shouldn't change too dramatically.

Q6600s draw a lot of current at even 3.4GHz and produce a lot of heat, if you don't want as much heat go to a 45Nm chip, they have lower TDPs.

Was cheaper to buy a TRUE than another quad Temps i can deal with now.

[mikeyakame]

Yep worked for me too, TRUE along with sanding down the cpu heatspreader to get a more consistent contact area! I get no more than 54-56c full load in prime95 on quite a warm day at 3.36ghz and 1.38v, 7x multi with 478MHz FSB 1148MHz DDR2, I'm extremely happy with that as it's a balance between High FSB and DDR2 freq and the CPUs performance across the board. High clock frequency alone isn't everything as alot of people seem to be in the mindstate of doing.

I'd rather have 4Ghz and 1066mhz mem compared to 3.6ghz and 1066mhz anyday......f**k volts

[newls1]

Any Q6700 OC's in here? I have an L724 Q6700 coming on tuesday and cant seem to find anything based on that batch code for Q6700. I see a few L724 Q6600's, would these be about the same in terms of OC'ing?

[jcool]

I just linpack'd my 24/7 setting for a bit:



Shame it has to make room for i7 now, this CPU has served me really well (it also did around 1,5 million BOINC points, so in a way it served all of us well).

Sold to Aerosupra who will continue its crunching legacy
