*Official Retail G0 Q6600 Overclocking Thread*

[Systemcepe]

Wow thank you everyone for your posts! I'm not gonna OC yet for a while. Though I think it could be nice to prepare this soon.

[blazin-asian]

hey everyone, finally put everything together last night and ran Orthos at stock and everything was good so i slowly upped it to 3 GHz (334x9) and it runs fine.

im testing at 3.1 (345x9 with 4:5 divider on stock vcore) and had to drop a divider because my mem is only rated at DDR1000.

is it worth upgrading to DDR1066 mem or should i just save $50? i was going to get this kit:

i would upload pics of 3 GHz, but thats just a baby OC so far

[zlojack]

The sticks you have should do 1066 no problem.

Go for 9x400 stable first, then start on the RAM...

I have those same sticks and with some pushing they do 1066

wow. go for 3.6 right away?

should i do 1:1 divider? i think default on the mb is 4:5

i havent had time to memtest yet, but will do it tonight to determine if i should exchange or not. i hear the GSkill 1066 can go up to 1200

[ZenEffect]

not stable at all... but not a bad screen shot either

Well, you could walk your way up slowly to 3.6 GHz.

A lot of people are getting that, so that's why I think you should shoot for it.

As for the RAM, I leave it alone until I find the CPU's sweet spot, then try to squeeze the RAM too...

The 4:5 would let you run the RAM at stock and also run a 400 FSB for 9x400

If you want, you could give the NB some more juice and go for 8x450 with that same divider you'd be looking at 1125 MHz RAM, in which case you might want to upgrade

I still haven't found any RAM that will go past 1100 MHz stable on my Maximus Formula. I've had ReaperX PC28000 2x2 GB, Mushkin Redline PC28000 2x2 and G.Skills like yours. Next on the way are the Corsair Dominators 2x2 GB PC28500. Hopefully they get to where I want them to go.

I didn't notice, are you on vista? is that why you want 2x2gb not 4x1 cos i reckon ocz flex would go that high I've had 2x1 stable @1280 for a month on maximus formula

Yes I am on Vista x64.

im not too much of an avid overclocker. i oced my old 939 system for about hte last year of the system life cause it was struggling a bit with vista.
went from 1.8 to 2.35 on a venice core. thats about the only ocing experience i have.


i hear thatthe G0 stepping is "designed" for a 333 fsb. does this mean people wont see any decrease in the life of the a q6600 g0 if they run at 333. i have one that im currently running stock. i started reading this thread and notice alot of talk about VID. im not sure what mine is, ill check when i get home. but on my p35-ds3l bios the "normal" voltage for the cpu us 1.3,so thats probably the VID.

question. how low do u guys think i can go on vcore to get stock speed if the vcore is actually 1.3

ques 2, is 333x9 really putting any more stress on the q6600 or is it a really safe overclock. i plan on using this system for at least 5-6 years.

ques 3 - my system loaded windows at 400x8 at 1.3. temps were at 36-37 idle. didnt bother testing/priming benchmarking but im pretty sure it would be stable cause many peeps here have them stable at higher speeds. would this lower the useful life of the cpu??

1. you can check your VID using Core Temp found here: http://www.softpedia.com/get/Windows...ore-Temp.shtml

the VID core will tell you what your BIOS has used for minimum voltage, but slowly lower it and test for stability to see what works for you.

2. any kind of OCing is stressing the CPU, but you have to watch the temperature that is a result of OCing. if you keep it at a safe level, then you should have no problems

3. even though you were able to load windows, you should still test your cpu and memory at full load to see if its stable.

[jton219]

so your saying the tempurture itself is what is hurting the cpu in terms of its longevity??. as long as i can get an overclock to work at the same or very close to the same temps as stock, (around 32-35c idle) there should be little to no harm done?

[blazin-asian]

i would think that running a CPU at a high temp for its life will degrade the chip quicker.

Well, you could walk your way up slowly to 3.6 GHz.

A lot of people are getting that, so that's why I think you should shoot for it.

sorry for the noob question, but what does bumping the NB voltage do? its the memory controller right? right now im testing 400x9 (1:1) at 1.45 vcore and running 2 instances of Orthos with 2 CPUs each. stable for 8 minutes so far......

load temps are as follows: 77/77/67/67 - is that normal?

if it passes, then can i up the NB voltage and drop my vcore a bit?

[zlojack]

Well, I think those temps are a tad high...but it depends on what your ambients are.

As to bumping the NB, it gives more stability for raising the FSB to higher frequency.

[blazin-asian]

what temps should i be trying to avoid? the highest it goes is 78C

also, what is the max i can bump the NB voltage to? im probably just going to bump it .1v for now and see how it goes. so far im 30 mins stable with 400x9 (1:1) @ 1.425v

EDIT: ah, core 2 crapped out after 45 mins. back to the drawing board.

[lefy]

this is my opinion...

80C is too hot
70C is max I would tolerate for benching, but
60-65C is max I would run for long periods, and
60C is max I would run for 24/7 overclock

71C is the thermal spec at processorfinder


and take these guidelines with a grain of salt... everyone has their own limits.

[JackeShan]

Mine goes to max ~71c with 3.9GHz and 1.535Vcore when playing games. I would not go higher than that.

[Hans Gruber]

I don't care what people say, you need 1.40-1.42v to run the Q6600 completely stable. Prime 95 is overkill, but for a short time 30 minutes or less will give you some insight into stability.

When you guys post your vcore, make sure it's CPU-Z or some other program other than your bios setting. My MSI undervolts significantly from what the bios says the CPU is running at.

I would say that anything over 75C for long periods is not a good idea. The Intel stock cooler idles in the 50's.

I can run my quad core at 1.225v all day at 3.2GHz but it could crash at any time and has, but is quite stable. Getting to 3.6Ghz takes 1.4v

My opinions are only for air cooling, not water cooling, but I think it may be similar. Water cooling just allows 4.0Ghz or more with 1.5v +

So even though it could crash at any time, you say it's stable?

You do realise that the fact you have a not so good, high VID chip doesn't mean that everyone have such units? It's not a case of what people say, it's a FACT that a lot of people run 3.6GHz completely rock-stable on voltages around 1.3v. And by that I mean 8-24 hours of continuous priming, not 30 minutes which doesn't give you any insight on stability, since the pc migh aswell reboot after 3 hours of testing...

As for the temps, I wouldn't go past 65C on maximum load for 24/7 use.
The CPU's life length is determined by temps, vcore voltage and ppl voltage. Just don't go above official intel specifics and it's all fine.

My 1st post here been here for sometimes for information and now I contribute something back....tks guy for all the good info.

XP64 Q6600 L740B154 at 4Ghz 1.525Vcore 3DMK06.
Watercooling system, ambience temp around 29-30 degrees.

Got my Q6600 yesterday. Overclocks very well.

The Weird thing is..for 3.6GHz I only need 1.35Vcore to be stable. On 3.9GHz I need 1.54Vcore. I can get it up to 4GHz but it's way too hot and need about 1.6Vcore. Also my cooler is unlapped so the temperature is not good. Max is about 71c when playing games.

Those are some nice clocks you got there.

[jcniest5]

Can someone who runs at least 3.6Ghz stable posts his/her BIOS settings, especially CPU and CPU PLL Voltage, NB and SB Voltage, Clock Over-Charging Voltage, CPU and NB GTL Voltage Reference and CPU Spread Spectrum. And whether you Enable or Disable DRAM Static Read Control and Transaction Booster (and what level).

Thanks...

check out the link. i have mine posted there. and also there are plenty of other ppl in the similar thread with results.

Hi guys
Can someone explain please what is the Vanderpool Technology ?
and what is the Purpose of the Execute Disable Bit?
and what they have to do with OCing could they be limitng me to the 3.8G that i'm stuck at?
thanks.
