Iy should be good for that - its a good HSF. Not as good as the thermalright 120 extreme or the ultima with good fans but good enough to o/c the q6600 to 3.6 .
 



Thanks, this timing and clock speed stuff is a new concept to me.
 
It looks like detailed explanations have been given already, so I will throw my vote in for DDR2-800. There's no practical need for DDR2-1066, even when overclocking.

If you want 3.6GHz (unlikely unless you get a GREAT G0 stepping) you will need an FSB speed of 400MHz. This equates to DDR2-800 at a 1:1 ratio.

Realistically you will need to lower the multiplier on your Q6600 to 8 for a final clockspeed of 3.2GHz. Don't sweat it, you'll never be able to tell the difference.
 

A lot of q6600 GO reach 3.6 or more on air with relatively low volts. The latest batches with VID of 1.2 are getting even higher on air- with water 4.0Ghz plus. . The one I have will run 3.8 (475x8)3dmark06 stable on 1.45v but not prime. So if you run a lower multiplier and can run higher FSB (say anything above 450 upward) you may be better with 1066 ram to run 1:1 cos not all 6400 ram o/c that well. 8500s will also give you a more or less guaranteed option of o/c to running on higher ratios e.g 2:3/4:5 etc to gain higher bandwidth. If you dont want to push it hard then buy good 6400 RAM like ballistix and its no problem - 8500 are after all only cherry picked 6400 chips in alot of cases..
 
Okay, maybe the G0 steppings are better than I thought they were. I still don't think a FSB of over 400MHz is necessary. Seriously, can you really tell the difference between 3.6 and 3.8GHz?

As a side note, I just realized that it is incorrect to say "an FSB." It sounds wierd, but it should be "a FSB." I won't be going back and editing my posts though :kaola:
 

Any ncreases makes a difference to scores in Superpi and 3dmark etc which are important to overclockers trying to get highest scores and squeezing the last out of the system or just the fun of seeing what it can be pushed to as a rule. The system performance on mine is a lot zippier and responsive with 3.8 - faster bus speed ,memory running slightly higher etc. unfortunately not fully stable though -lol!. So I run 3.6 quite happily 24/7 and its pretty good for all games out at full maxed settings(except crysis which eats PCs) - I have a decent graphic card which helps a lot as games now tend to be re GPU restricted . At 3.6 itw great for video editing, Burning CD performance etc. So unless your in it to see what you can get it maxed to stable - 3.6 is great.

If you havent read it already check this overclocking guide for optimum performance setting re what you actually gain or dont from increasing FSB etc. http://www.thetechrepository.com/showthread.php?t=195
Very interesting and informative
 
Guys, if I may ask, how does ram mhz effect cpu overclocking? I'm planning to get an Q6600 as well and overclocking to 3.0, and I didn't know that I have to pick the rams carefully until now.
 
Normally it is best to run the ram @ 1:1 timings with the cpu.

So even a Q6600 @ 3.0 only needs ram that runs at 667.

Thats why many say just get 800.

You can even drop the multiplier 1 notch and run 3.2 @ 800...

For extreme memory over clocking you can drop the multi further...so you get moderate CPU speeds(still over 3.0 and fast ram)
 
@ sesdave: So in gaming and every day use you can really tell the difference between 3.6 and 3.8GHz? I don't have the right to doubt you because I have never even seen a Q6600, much less been able to use one, but jeez that's hard to believe. I can't even tell the difference between 2.0 and 2.5GHz on my x2 3800+ unless I'm benching.
 

Not quite - I said the PC seemed zippier. I was refering to the operating system(I run Vista x64 so I need all the help I can get-lol) You get slight increases in benches etc but no real gain in games and real day apps. Thats mainly due to the fact the are not optimised to use mutithreading. The only real advantage a Q6600 give you over dual core at present is improved scores on 3dmark06 and times on video rendering and burning CD. But the are the furture as games and apps will be moving in the direction of multithreading. But they are cheap and overlcok relatively easily with a decent motherboard. But that said penryn,x48 and DDR3 are round the corner. Another expensive adventure for no real purpose apart from fun - its as bad as when I used to play with cars to make them go faster and look flashier- lol!
 
Ok, help! Im on a 680i and i have the ultra tec cooling system, but for the life of me i cant get any better than 315, not even 315.25 ( vista doesnt even start then) and a stable one of 305 resulting in a horrible OC of 2.745 MAX.

Now, I haven't messed with any voltages as im not sure whats safe and how they effect the clocking ability. Am I doing something wrong or did i just get a complete dud?
 

Quads clock best on the P35 or P38 motherboards. If you have a GO you should be able to get upto 3.6 or more with good cooling . If you arent intending to run Crossfire get a p5K deluxe or equvalant. The P38 are more money for not much CPU performance gain (if any) over the P35. The main advantage they offer is full crossfire performance.
 
Ok, i did this on air

booting and running CPU-Z doesnt prove a lot - just shows the CPU has potential but may fall over with the first app you run.. Do you have a prime 95v25 run at 4.0 GHz to post?
 
I used the above link to O/C my Q6600 on a P5K Premium motherboard.

I have a Scyth Mugen Infinity heatsink and use Corsair 2GB PC2-6400 C4 XMS2 (4-4-4-12)

This was my first try at overclocking and was very happy to find that I have reached 3.6GHz using air only. Temps are around the 40-50 degree mark for the CPU and 38-42 for the Mobo.

FSB was set to 400 (x 9) = 3.6GHz.

I'm sure I could get more but scared to try :)

Memory is running at the stock 2.1v (noted on the memory modules) and is happy at 4-4-4-4. Not sure if I can o/c these more but all seems well.
 
Right now the **** memory chip is the Micron D9 if you buy your ram made from them it will perform well, no need to go over PC2 6400.
All this other stuff is just Fapp Fapp Fapp.
Most every Q6600 will OC to 3hz without much trouble at all, and that beats the Extreme Quad.
As to going with 4Gig of ram, there is just no reason to do it for most people.
 



LoL then you might as well say stay at 3.4 cuase is there really any difference between that and 3.6 or hell might as well stay at 3.2 since there isnt much difference from 3.4 or hell ..back off to 3.0 since....... this is O/Cing, every jump is necessary =)


 



Actually alot of the games at higher resolution and lower resolutions are limited by the CPU since the GPUs are so much more powerful.

Cards like the HD3870 and 8800GTX etc... series need every ounce of juice the CPU can throw out. Also remember the difference from an single core CPU like a P4 or an Athlon 64 from say 2.4 to 2.6 might not seem like a whole lot, but a 4 core CPU going from 2.4 to 2.6 is a great jump, that FOUR extra cores giving an overall .8 which is almost a whole 1.0ghz jump. So applications that can utilize the 4 cores, or even 2 cores get a much greater boost then a single core CPU.

Here at work we have a server that renders 20G+ graphics files to be send to an HP1500 silex printer and since I put a C2D 2.0 ghz in it and the difference from the P4 they originally had that was 3.6 is a bit more than 50% faster in rendering times. Even though the CPU is 1.6ghz lower.

 
Q6600@3.6 on water. To be honest, I couldn't be happier with a 8800GTS 640. Yeah, yeah...I know there are better cards out there, but I have the GPU under water as well, and it runs quite well at 700/950...but have gone as high as 725/1000+. They seem to be a little more stable with the memory clocked a little slower. I just need to tweak with my RAM since I just bumped up to 1066...
 
If you want great cooling without the hassle of water or vapor, go with either the Coolit Eliminator or Freezone. I have the Eliminator on my

workstation, Q6600, P35 Pro, 8 gig 6400 Patriot memory 1:1, 8800 GTX, etc. Overclocked to 390x9, vcore 1.27 actual 1.34 in BIOS. The Q is a newer G0,

1.2 vid. On mid settings for the Eliminator, ambient around 21C, 100% load on Prime95 for an hour, temps around 36 to 40C CPU, max of 55C on the

cores. At idle CPU ~ 15C, Cores 19 to 22C.
My render farm has 3 Q's on Gigabyte DS3L's with 4 gigs of OCZ 6400, 1:1, all running at 370x9, 1.29 to 1.31 vcore with Thermaltake Big TYphoon's. Temps average around 55C on cores under full load.. My E6600's are on P5W DH, same memory, same cooler, 390x9 at 1.42 vcore. Average a couple degrees higher.

I have a Dell (sorry) XPS 420 Q6600 2.4ghz 4x1 GB mem.@800 and HD3870 x2 Graphics card. Does anyone know of software to overclock either the Processor or the Memory?
I have seen some pin hardware overclock Pics but would like to overclock with software.
Dell said that this system cannot be overclocked but they are not always correct and I'd like to prove them wrong. thanks
