*Official Retail G0 Q6600 Overclocking Thread*

[CikaNovo]

For the past couple of days I'm trying to get my new Q6600 STABLE AT 3.6 Ghz but without succses. It will run Prime 95 25.4 for 2 hours(then I stop it manually), and remain stable for playing games,video encoding..., basicaly anything. After couple of hours and sometimes even the next day computer locks up while on desktop,doing nothing or sometimes while playing the game.

First I've tried with higher VCore but it's all the same from 1.375 to 1.45. Then I moved on to adjust the other voltages and tried different voltage combinations for SPP, MCP, FSB and HT, and noticed that they are best if left at AUTO(which is completly different from my previous Core2Duo E4300 that needed these voltages set manually for decent overclock). If I set these voltages at anything else then AUTO computer restarts or fails Prime in matter of minutes. Memory is out of question because it's completly stable(tested with Memtest 86+).Also, tried x8 multi with 450 FSB and it wouldn't even boot.

Does anybody have any suggestions on how to resolve this? All help is very much appreciated.

this should get a 3Ghz OC ???????, using defult voltage, dont really wanna change it. Its all i want from it.

Its quite cool in this room, but not freezing or anything, about 17c.
Using a Ultima90 with 7v fan.


stats while priming



PS. if theres no image, its the frikn ihost fault.

hey Gunnz,
what r u using to display all of those temps?

SuperPI 32m is nothing to stress Quad core CPU. Mine can run superPI 32M @ 4 +Ghz 1.44V but to stabilize 4 cores together need much more Volts. All 20 Cpu's i've tested can run 4ghz 32M some of them toh 1.45 some with 1.5v , so nothing special. Run Prime95 that's what can really stress it
Here is mine last B chip

anyone owned L727A932 this batch?mind to show ur result,thanks

[Avman]

This is my latest adjustment - still working on things, but this is my first push higher than what it shows in my sig since I changed to a P5k Premium board and some new Patriot Ram

[stureah]

I just fired my q6600 (G0) up from 3.2 to 3.6. So far I had to use 1.5 volt to + damper to get it to stabalize, but I'll do some more tweaking. I've left the rest on auto. I'll tweak some more later. I really just wanted to see if I could get it to 3.6. The temperature in the room is really warm as well.

The only issue is that 2 of the cores stabalized at 78/79, and the other ones at 2 degrees lower.
It's really not a problem during gaming, since no game pushes the CPU that far.

If you guys have any tips for any settings or anything please let me know.

Actually from what I've seen so far the A batches are outperforming the B batches, and the most consistent week for a good overclock is week 26. So look for a L726A*** quad and you have a really good chance of getting a pretty nice overclock

Just got a G0, L726A from ClubIT.

Running an old school Asus P5B Deluxe WiFiAP BIOS 1215, Thermalright Ultra-120 Extreme w/Nexus 120mm, a dime under the bracket...

POSTs at 3.2ghz (8*400mhz) and 1.350v but doesn't even get to the Windows load screen, self reboots. At 1.3625v it makes it to the Windows load screen and reboots. At 1.3750v it makes it almost fully to the Windows desktop and then reboots. VID is 1.3250v.

Backed it down to 1.3250v and 2.8ghz for now, if it survives Orthos by tomorrow afternoon (~18 hours away) I'll see if that helps the AS5 set and if I can crank it a little harder. Disappointed so far.

I've got two other Q6600's here... one is a G0, L724A from the tankguys preorder. Did 3.2ghz (8*400mhz) at 1.3625v just fine, but at 1.350v core 2 consistently failed Orthos between 4 and 8 hours. Handles 48hr+ of Orthos with a 3D program just fine tho. Booted right up at 1.350v tho. VID is 1.2750v.

The other is a B3 from Fry's 4th of July sale... L644G, booted up just fine at default voltage (I forget what, 1.325v-ish?) at 3.2ghz (8*400mhz) and was rock solid for 48hr+ of Orthos with a 3D program running as well...

Will probably end up keeping the B3 and selling both G0's for a slight loss from the way it looks.

Its your motherboard man, change it to a P35 and your Quad "G0" will fly.

[continuum]

Can't do that yet, waiting for X38 boards to come out, then I need to find one that'll work with an Areca ARC-1680 for my 4TB array.

Hmm. Good point though, maybe I'll hang on to the B3 and the first G0 til I can get an X38 board, then see how they do.

[continuum]

Given that I just had a complete system lockup at 2.8ghz on my third Q6600... maybe it's time for that new MB sooner rather than later?

[GameGuru]

Hey Guys, can someone help with my settings please? Trying to reach 4+. Here's a screen shot of my current settings running @3.825, thanks! Vcore is running @ 1.48 (Multimeter), not whats showing below.

[RLM]

Up the vcore. 1.6v (1.58v) maybe. if that fails, up the cpu vtt and mch.

That's what I'd try anyway

Thanks RLM I will try this when I get home tonight.

hey u guys with the p5k,
i still got my g0 @ default..
who can gimme a lil step-by-step list of what to change in BIOS ?
i'd like to aim it @ 3.4Ghz..
im really clueless out here

TIA

[stone_cold_Jimi]

Frying in the old town tonight

Hehe, having a play with my G0. It's not "best of breed" for sure, look at that VID. None of your fancy cooling there, the stock Intel HSF admirably not coping with the load lol, ambient was 20C. But credit where it's due - 20 minutes of prime and no crash, it's a trooper. FSB seems to hit the wall at 435 at the moment, though I haven't tweaked the PLL and FSB volts hardly at all. Mobo is a P5K3D BIOS 0604, RAM is way understressed CellShock DDR3-1800 (uncooled as yet and I don't want to burn 'em), just running on auto.

try checking my post #1235 on this thread... im using p5k-deluxe wifi, should more or less be the same

I managed to get my G0 Q6600 prime stable with these settings:

FSB - Memory Clock Mode: Unlinked
FSB (QDR), Mhz: 1600
MEM (DDR), Mhz: 1066

Vcore Voltage:1.4125
FSB Voltage:1.3
SPP Voltage:1.4
MCP Voltage:1.5
SPP<->MCP Voltage:1.35
Memory Voltage:2.00

Here is my 24/7

vcore 1.52v

[gengstapo]

simple setup:

cpu vcore: 1.48v(BIOS), 1.42(windows idle), 1.37(windows loads/ stressed)
ram voltage: 1.97v(BIOS), 2.02v/ 2.00v(over volt. in windows)
fsb termination volt.: 1.40(BIOS), 1.42v/ 1.41v(over volt. in windows)
NB volt.: 1.45v(BIOS), 1.50v/ 1.51(over volt. in windows)
SB SATA: 1.55v(BIOS), 1.55v(windows idle/ loads)
SB volt.: 1.075v(BIOS), 1.09v(over volt. in windows)

RAM: 5-5-5-15 2T, 1:1
speed: 426Mhz/ ddr2 852

ps: if i manage to hit atleast 8hrs of prime, it would be my 24/7 setup.. :hyper:

im so jealous you guys seem to be doing so good with your boards i hate mine i was doing a build then when i started it up i got infamous "--" post this will be my 3rd or 4th time rma'ing my evga 680i i think i should buy a new board now but am unsure what to buy

[CikaNovo]
