*Official Retail G0 Q6600 Overclocking Thread*

[cincyrob]

B3s aren't very good...

I'm hitting a serious FSB Wall here, 450MHz... maybe less.

wow 4.0ghz on a quad??? thats awsome... so are you stable at anything less? 400-450?

and this is on the B3 stepping?
how high can the G0 stepping go?
i really wasnt thinking of takeing it that high. maybe to 3.4-3.6 i thought that would be pushing it some... what would a good everyday 24/7 OC be for this CPU. no matter what stepping i get? if i order online its a toss up in what i get. if i find it in a brick and morter shop i can see what im getting.

I was talking to someone else who wanted to buy a B3.
Mines a G0, L743
Why would you want to buy a Q6600 when you already have an E8400?

[Pellepel]

Whats a good SLI board to over clock with Q6600? I heard Evga 750i? Sorry I'm in the market for a new board.

Unfortunately, none. My 750i's 6-Phase Analog power starts to give once I push 3.8GHz with this processor.

Even with the 8-phase analog on the 780i/790i, you could run into trouble.

I see no reason to go SLI now, as Nvidia's Graphics cards aren't offering much-if any performance advantage anymore.

LOL OK i thought that was intended for me.. as im looking into a Q6600 and the only ones i can find are the B3's

well for one i have a GA-P35-DS3R mobo and with the E8400 45nm chip it tends to run warmer than others with this same CPU and different board. everyone that i have talked to that has this board and a 45nm chip it runs warmer than most.

seeing the Q6600 is a 65nm chip with my mobo the temps are nice and cool even nder load...

plus the Q6600 has a little more power. considering it is a quad.

[Loser777]

Stick with the E8400. DONT BUY A B3.

My Striker died and I don't even want to deal with it any more. I can't even get a good stable clock pass 3.0 GHz. Going to RMA it and put it on a different system. Make use of my E6600

I have no choice but just to stick with SLI(8800s gtx). Will it be worth it to go with Evga 780i? The price looks so good on Newegg. And which brand in that bracket has been known to be a great overclocker? Thanks.

I'm sick of dealing with Nvidia boards... I say it's not worth it. Sell one (or both) of your 8800GTXs and get a good Intel Chipset board and an ATI Video Card. The nvidia chipsets are a boatload of problems that just aren't worth dealing with. Video Corruption, Bad overclocking, Bad performance, and Poor power regulation are just four bullets on the list. My Q6600 can't get past 3.6GHz on this board because of power problems, and 451FSB won't even work.

[CBird28]

Agreed ^

[_Pain]

No, not all L80x are bad. Recent reports show that L807A/L808A are the new winner. Where do you get your L807A from?

I've been lurking around in the past anonymously but registered to thank you for the information =)
I got a L807A chip which overclocks at:

1) 9 x 266 (2.4ghz) @ 1.16v for 2hrs+ prime95 stable (in CPU-z) Load Line Calibration (LLC) on --> on motherboard AUTO the voltage supplied is 1.28 (is 1.16 too little?)

2) 9 x 333 (3.0ghz) @ 1.232-1.24v (in CPU-z) prime95 stable 3hrs (with LLC off)
3) 9 x 356 @ 1.296v (3.21ghz) prime95 stable 3hrs (in cpu-z) with LLC on --> is this too higher?

Motherboard: Asus P5Q Pro
I tried to overclock to 9 x 378 manually but setting vcore at 1.36250 in bios, I'm scared of wrecking the chip. (I am new to overclocking sorry)
computer is planned to last 5+ years =(

oh also i modded/made some aluminium mosfet heatsinks, do i have to put some thermal paste or pad before screwing them onto the mosfet area, or can I apply it directly without a thermal pad? (I dont wanna do a short circuit)

Can anyone offer me any assistance and tips on overclocking? Thank you very much =)
I'll post some pics up later

i have an L749A8 - pack date: 02/26/08

havnt opend it yet though. anyone know if this ones ok??

Sorry to go a little off topic but I get some great results from my sli boards. The msi is a very good clocker, stable, and reliable. Sli works flawlessly with it. I haven't experienced any of the issues that loser describes. I'm just now setting up a 790i but that's also an excellent clocker.

It looks like you got a Q6600 with VID around 1.27 ~ 1.28v, which is not bad. Setting vCore at 1.3625v is ok, but you must have a good cooler to curb your CPU temperature under 65C (preferably under 60C). Check Thermalright, Zalman, etc. for their top offerings. If you already have a top-tier watercooling system you should be able to hit 3.6GHz at that voltage.

oh also i modded/made some aluminium mosfet heatsinks, do i have to put some thermal paste or pad before screwing them onto the mosfet area, or can I apply it directly without a thermal pad? (I dont wanna do a short circuit)

I'd use non-metallic based thermal paste (e.g. Arctic Ceramique) for applications like this. Yes, you must apply a thin layer of thermal paste in between the contacts or you are wasting your heatsinks. There also exists permanent thermal adhesive (like this one) for you to attach tiny heatsinks without the screws. Hope this helps.

That stepping seems to be a mixed bag so you're on a lottery. I've tried a close stepping L748B with VID=1.2875v and it made 3.6GHz with 1.45v (reported by Everest; in BIOS the vCore was set at 1.5x v). If your store allows open box return go try it and keep us posted.

[Jamesrt2004]

mine wont like 3.6 without 1.54!!!!???

that normal?

I was originally gonna post something else, but upon typing that post, my 11hrs Prime Stable and Linpack Stable 3.6GHz OC-1.372v-1.384v... Suddenly hung when I was typing this post.
I raised voltage a notch in BIOS, started testing, hang.
I'm at stock now and everything's stable...
My problem with this board is that it's extremely fickle. With my last chip I had this board benching at around 480FSB. After I got rid of the last chip because it was a bad clocker, I pop in this low VID bad boy. 3.6GHz was stable at 1.372v/1.384v so I thought if I can't get to 3.8GHz, I'll at least have 3.6GHz with this board, which is a pretty decent 24/7. That's not even possible anymore, and I'm seriously starting to doubt the quality of this board.

What's weird is that setting higher voltages causes the crashes to happen FASTER than they would at a LOWER voltage. And crashes happen strictly based on the amount of load also. I had 3.8GHz running for about 5-6 hours... @ 1.464v... I run Prime, and it crashes in about 1 second. I run one thread of Prime, and it takes about 10 minutes. I know that this behavior is pretty common with an unstable chip, but it doesn't explain how higher voltages crash FASTER, unless something is wrong with power regulation.

My other thought is that the Chipset could have potentially degraded... I was running it up to 1.55v (BIOS MAX), with my benching runs before, and I ran it at 1.5v 24/7 with my previous OC.

The highest I ran my chip AFTER setting my stable 24/7 OC was 1.58v LOAD for about 5 seconds before Prime failed.

Maybe just one of the bad MB? 3.6 for Q6600 is pretty good. I pulled the trigger and bought the 750i SLI. Didn't want to deal with the selling and stuff, and time is a factor for me right now.

I've read a few reviews on this board. One review claimed that 400x9 had primed stable. They changed vcore and a few other settings, but most on auto and primed stable...could just be lucky and got a good MB. But they used Wolfdale. But another review claimed great success with Q6600.

Anyhow I should get mine this Thur, hopefully it will clock well...

[drizzt5]

Mine has a vid of 1.225, I get it completly stable at 3.6ghz with 1.3875V's. I want to push it alot higher for daily use, maybe another 400mhz. I just need to take my mobo settings off of auto and start to do some real OC'ing, lol, I'm just lazy.

Tested 8hours with OCCT (idk if any of u use this program) 100% load completly stable, highest temp = 51C's.

I didnt think any store lets you return after opening it

too late i sent it back i managed to finaly get a stable oc at 3.8 with my e8400 so im just keeping this

[drizzt5]

3.8 water cooled? on a 45nm?

Heat is obviously not the issue, just try to get 4ghz please...

[FabricioGS]

Here is the max I got stable to run Super Pi 1M (on air):



I'm still a litle bit noob about the advanced features in my bios so I couldn't prime at more then 3.6GHz. At 3.7 the system restarts after a few minutes. Maybe my Enermax 535W is not holding that much overclock or I'm missing some extra voltage on some specific option in BIOS.

[Loser777]

What voltage are you running for 3.7GHz?

[FabricioGS]

About 1.45v set in bios (I don't remember exactly). I'm currently at 3.6 (450x8) as 1.4250v set in bios (1.4080v in Windows). This is prime stable.
