*Official Retail G0 Q6600 Overclocking Thread*

[Leeghoofd]

how far can a Q6600 be overclocked with a zalman fan or some sort of copper heatsink ?

Depending on the batch between 3 and 3.4Ghz max on the Zalman, I've had several now (9500, 9700 and 8700) and they are average coolers... better than the boxed ones for sure but to push to 3.6ghz and more I would recommend looking for another brand...

[deadalvs]

thanks, Leeghoofd !

by the way... since you have more experience. i'm thinking of future investments in q6600 rendernodes since they give the best price/performance ratio... especially when overclocked of course. now. i'd need also cheap cases and i thought about 1u or 2u rack cases.
is it okay to overclock to 3.4 with a better fan (i'm not sure if a zalman would fit in there) in such a small case or do you see significant problems with that ?

what mobo and what ram is best / cheapest / most reliable for such a task ? there are so many possible rigs around - i'm a little lost ...

Best, cheap and most reliable to overclock a Q6600 is definately a P35 board. They should all easily OC up to 3.4GHz as it is only 377MHz. If you have a good batch running low vcore, no problem. But, if you need high vcore, let's say above 1.4v, better go with a some high end models as the quality of the PWM is vital to OC a Q6600 on high vcore. For RAM, get any PC2-6400 kit as it will afford the 755MHz on RAM at 1:1

About the case, I don't know

[Sword]

Yeah My Q6600 L747B274 vid is 1.32v. Damn what luck!
Would my new DFI LT P-35 be able to get it to 3.4 without too much trouble?
I have 2 kits of Gskill pc6400 HZ and Xigmatek HDt S1283 HSF.Corsair HX 620 (11.90 on +12v rail ,seems a little weak)

Can anyone confirm if this Q6600 FPO L640B814 is any good?

Can anyone confirm if this Q6600 FPO L640B814 is any good?

I had one. It wasn't a great clocker with a 1.30VID. 3.3Ghz with 1.43v and would not make 3.4 with 1.5v so I put it in an HTPC and sold it. Bought a L738B024 that makes an easy 3.6Ghz. Both were installed in a P5K-E and a P5K-Premium for testing.



Now that doesn't mean that your one is going to be the same as the one I had.

[=Pseudo=]

Here´s my contribution...regarding batches

Part I - Rig
CPU - Q6600 (L719B, L726A, L727A, L728A)
Board- ASUS P5K dlx/ Blitz Formula
Mems - OCZ Reaper 8500
VGA - HD2900XT
PSU- Corsair HX620W
Cooling - water cooling (CPU, NB, VGA)

Part II - o standard

In general they all did this:


+/- 0.02 vcore

Part III - VID

L719B
VID -1.3000

L726A
VID -1.3000

L727A
VID -1.2750

L728A
VID -1.2875

hard to co-relate VID vs better/worse overclocker...

Part IV - the reachable
3 out 4 CPUs tested run spi @4100 however, Only one went further..


Part V - FSB wall
Among the FSB walls I found one CPU max out @445 and the best was around 500


Part VI - the BEST






Note that not all settings were optimized (mems/voltages) but you already can see nice differences

Could my G0 be one of the bad ones? i can get a solid 335FBS @stock volts, but if i go for a 400FBS i have to bump the Vcore to 1.43 and while i can boot into Vista x64 once i run Prime i get a BOSD.

Side note:
i just bought my system while i cant return the CPU now i could replace it...should i replace it w/ E8400?

Is that 1.43 in the bios or when its loaded up? I'd up the vcore but it looks like you might be at the limit of your cooler according to your other thread.

My abit ip35 pro is set to 1.505 in the bios but it dips to 1.43 under load. These guys respond very good with the addition of more voltage.

No trouble at all. The only issue might be your cooling. I don't know what the weather is like in you house and what the rest of you system is like (such as case and other fans).

heres is all my L804 1.325 vid can muster:

1.6vcore in bios (1.55 under load) Vdroop disable. speedstep on.

hey dezio... what are you using to cool that ?

[deadalvs]

ah the nirvana is actually a fan... hehe... sorry !

[Dezio]

Exactly Nirvana NV120 + 4x120mm fan around a case

Thanks, Saint -Francis,I love my DFI! It's pretty hot around here Ormond Beach FL.(94.F,outside,77 F,inside) I have a CM 830 evo case.(build in progress) just got my Zotac 8800gtx yesterday!Thinking about using Scythe S flex 1900 rpm( for the side fan cage) I got cold feet about watercooling in the past ,but am a little more comfortable with doing it now.still have unused 77 Bonneville heatercore,old Swiftech mcp 6000? water block (skt478) want to go with exterior rad (tool box ghetto mod) stiil need pump,fans,masterclear tubing and either D-tek fusion or Swiftech Apogee GTX(?) cpu block.

If you look at my signature you will see what I have done with my Q6600 and mY DFI LanParty p35. I am running the Q6600 @ 3.6 (which is a nice smooth 50% overclock) and my max temps with an ambient temperature of about 80 F. (no air conditioning in my house) are and have never been higher than 50 C. The CPU is under load quite often and it is usually in the mid to low 40's during the day. I''m using the same heater core you have; well I have two of them. But when I only had one it was still quite efficient. Even if you have a high vid, if you water cool it you will be able to OC much higher with much more safety and peace of mind.

[Unoid]

nice francis, I need 1.50 to hold 3.6ghz, C1E speedstep and vdroop enabled.

[DIE-TEMP]

I had a Q6600 with vid of 1.325v which needed 1.52v for 3700mhz stable.

I sold it and got one with vid of 1.235v which passes Pi 1M upto 4016mhz with 1.488v loaded (1.500v bios) on air.

I need to fit my waterloop to see if I can go any higher with it.

Nice chip. Results are on par with my L737B, but your temps are about 10c lower. What's your ambient temp?

I'm seriously considering selling my Q9550 and going back to the Q6600.

Hi!

Just bought:


It's a L808A892 with a 1,225 VID
On WC it OCs to 3,6 with 1,33V (loadline cal. on). What is the max safe VTT for these chips?

Hi!

Are you serious?
An L8XX that does 3.6GHz with 1.33v... amazing.

Check the Core 2 OC thread for max safe VTT.
