*Official Retail G0 Q6600 Overclocking Thread*

[situman]

What kind of volts did you need for that?

Here's mine @ 3.4ghz with 1.4v.

1.5125 in bios on P5K-Premium
Mem is 2.2v
NB 1.25 Any higher instant Prime failure. Might have to watercool the NB.
SB 1.20

[Ace-a-Rue]

hmm, i've got a 1.25 VID G0. Compared to what i've seen, seems pretty low... i wonder if that's good or bad. I have to do that TR U120 Extreme mod before I push it.

mix bag results with high and low VID...i think it depends more on the quality of cpu die (wafer).

[GripS]

I would have to agree. There is a user over @ DFI Club and he's got the very same batch as i do but his VID is a tad lower. He's having trouble getting past 2.7ghz with that one. For sure it seems not all 'G0' are good overclockers.

[Brother Esau]

Well they run allot cooler at the very least

[nicepun]

Anyone out there with high FSB issues aside the folks with RAID enabled? Specifically people with VID: 1.3000v

[djbon2112]

3.6 GHz (400 x 9) @ 1.4 volts (BOIS)/1.368 (CPUz). 3+ hours Prime95 stable.

I got 3.8 @ 1.5 volts (BOIS) which passed the 32M SuperPi test, but failed after about 5 minutes of prime. I suspect if I was a little insane and tried upping the voltage even more, I'd get it stable. But that wouldn't work for 24/7 use so I'm stuck here at a measly 1.2 GHz OC :p

[strange|ife]

some more results 4m pi runs, 4ghz 4-4-4-15 now on memory instead of 5-5-5.

4 instance, i was able to clear 4m with 1.55 droop, 1.63~ set in bios..I might go for 8m run next



At that vcore prime passes for more than 5 mins but gets over 75c, HAIDES. under cold or water i bet this chip would rock, unfornately iam to broke to either

[Omastar]

Here's my initial result:



VID: 1.300v
Batch: L721A814
Pack date: 7/31/07
Mobo: Intel D975XBX2, 2777 BIOS
Vcore (at 3.2GHz): 1.325v BIOS, 1.315v Windows (idle), 1.31 Windows (load)

Anyone else with this stepping? What are your results?

[The Stilt]

interesting to see how DDR3 adds a lot more time to the SuperPI 32M tabulation...i'm a bit surprised with that much difference especially when you consider your 700+ memory speed.

MCH timings are loose as hell and the bandwidth simply runs out with four threads.

DDR3 with correct timings can easily run out DDR2 in bandwidth and latency.

Q6600 makes my head ache since it is both multiplier and FSB limited.
The board (P5K3) cannot run that FSB with 1:2 divider so either it is lower CPU frequency (equals lower FSB) or lower dram frequency. In this case lower dram frequency hurts much more.

With 3.8GHz clocks the time was 16:26 so the decreased memory bandwidth hurts like hell.

[NJDevilsFan21]

Finally had the balls to do 3.6GHz air cooled on my Q6600.

Mobo: P35-DQ6
Batch: L723A841
Voltage: 1.39375V bios -> 1.36V idle (cpuz) -> 1.344V load (cpuz)





Now... if only am ambient outside the case was 65F and not 75F, or better yet, if I only I had water cooling!!

[scorpion]

getting rid of the d975xbx2, what would be great mb to run with my q66oo go!!!!!!!!!!! thanks

[Omastar]

getting rid of the d975xbx2, what would be great mb to run with my q66oo go!!!!!!!!!!! thanks

abit IP-35 Pro or Asus P5K-Premium. Although my XBX2 is clocking my Q6600 pretty well so far. I'm waiting for X38.

[scorpion]

yea,my other xbx2 was a great board until i put 4g of ram in it and it killed the mb.then they sent me this bs of a board and its killed 2g of ram and cant overclock past3.0 that sucks.thanks

[scorpion]

yea, i had great board before i had to rma it. this bs of board they sent me has all ready fried 1g of ram and will not overclocl past 3.0. this sucks

[scorpion]

sorry about the double post!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[Ad1tya]

Was only trying to get a sub 12sec score.
The chip, definately has it in itself, to get to 4.3Ghz.

Theres a Typo in that Notepad file, didnt notice it . Its on an Abit IP-35 Pro. Not Asus P5B Deluxe.

Btw, vCore was ~1.58 real.

[djbon2112]

Well, after seeing how crazy some of you guys are with the volts, I tried again. 4.0 baby! :p 4.2 wouldn't boot regardless of voltage, and this one failed after about 5 minutes of Prime95, but it's still cool regardless!

L723A795

4.05ghz 1.48vcore

[whitebrow]

I just got my G0 yesterday, and I've not had a lot of luck overclocking. Can you guys help me out?

System:
Q6600 G0 L724A760
Ultra 120 Extreme + AS5
Asus P5B-E (Bios 1601)
2x1GB G.Skill DDR2-800 PK
X1950XT

So. Prior to this I was running an E6400 at 8x375 and it ran real nice that way. I got the ram down to 4-4-3-4 running 1:1 with 2.0V, so I thought I'd aim for 3.375 GHz with the quad.

Not so easy. I can't seem to take it over ~320MHz and get into windows. I've tried 333MHz with a bit over 1.4V with no luck - it'll restart while windows is loading or as soon as I log in. I'm in windows at 9x310 right now and its running real nice IMO, idling at 36-37 (one core shows about 6 degrees lower at 30), I believe my voltage is set at 1.325 in the BIOS which I'll verify along with the rest of my bios settings before doing anything else. Load temps stay decent as well, low to mid 50's. The parts could probably use a lapping but I'm not really into that at this point.

So, motherboard issue? My brother has a P35-DS3R with the E6400 which runs well and I'm thinking about dropping the quad in there later tonight just to see what it does.

A poor windows install maybe? It does take a considerable amount of time to load up but it runs well at a lower fsb.



I'm going to try taking this to 6x375 to see what it does, if that doesn't go well then I'm going to put it in the P35. Anyone heard of this type of issue?

[GripS]

Whitebrow... You have the very same batch as i do. What is the VID on your chip? Use core temp v.095 to find this if your not familiar.

Is all you have tried is increasing CPU voltage?

nice job
is it L623A or L723A?
and the entire code is?

[denden]

finally I have tweaked my 965 dark last night achieved 3.54G @ 1.42v loaded 2 hrs prime 95 stable

My VID is 1.2875V. All I've really tried is increasing the voltage, but I can't even get into windows at 3GHz. I was going to play with it more tonight but I'm putting it off until tomorrow afternoon. I'm fairly new to this, I just built the rig initially in January. Are there other things I can try? My plan is to take note of all the Bios settings, try getting it at 6x333 and higher if I can, and then put it into the P35-DS3R.

I know that my ram is stable at 4-4-3-4 375MHz (750) 2.1V, and I've gotten into windows with the FSB up near 500 with an E6400. This is not with the new 1601 bios though. I don't believe I can downgrade any more than the version previous to this one without losing G0 support.

[Ad1tya]

^^ Set the NB voltage to the highest you can.

I need atleast 1.55v on my P5B Deluxe, to get to 350FSB and above.

[denden]

I also put 1.55v to nb and set the boot-up-clock to 390 otherwise it wont even post.
