*Official Retail G0 Q6600 Overclocking Thread*

[vws]

some people say the L80 chips are bad overclockers, is that right ?

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

Any clocking results on this cpu mate ?

[finnsopp]

Just got my new Q6600 L807A420 Vid : 1.240V

Only has a stock cooler yet soo i dont wanna push it too far with this cooler, had it up`n runnin on 333X9 for an hour on OCCT, My temps reached 70C soo Occt auto stopped the burn in soo i cant wait too try this chip out when my new Zalman comes in a couple of days =)

Hope i can get it too 3.6 on air

Any1 wondrin where to get one of theese? Try w w w . k o m p l e t t . n o

Its a norwegian site with 100+ L807A`s for sale =)

I'm waiting for my TR 120 eXtreme then I will start testing it

My Q6600 has the same problem :

3.4 with 1.425 in BIOS (1.36-1.39 in CPU-Z)

But to run it at 3.6 , I need 1.525+

Temps are rather high though with hottest core Idle@59C and Load@71C
Maybe because I use Intel Stock HSF
When I get the OCZ Vendetta 2 and AC MX-2 I will try more

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??

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.

Fire it up and lets see!

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

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.
