Q6600 Overclock

Oh cool, thanks.

Also I just realised how dumb I sounded. 775 coolers are still very much very easy to find. Don't know why I thought otherwise.

Yeah the modern coolers still cater for 775 socket :).

These two are also top end air coolers:

Prolimatech Megahalems:

Noctua NH-D14:

Here is another good one though you can't attach 2nd fan on it:

Titan Fenrir Evo

All the coolers I have listed including what I am planning to buy are excellent for overclocking Q6600. :)
 
hi guys back again.

I have been reading on power phases and mofsets though I am not really familiar with this topic. It seems more mofsets mean the voltage regulator of mobo runs cooler and provides more efficient transfer of voltage to cpu and this results in more stable and higher overclocking. Here is th link:

From this it would seem that Asus P5Q Deluxe has 16 phase voltage regulator or 16 mofsets whereas my mobo Gigabyte GA-EP45-UD3LR only has 4 mofsets around the cpu area and thus has a 4 phase voltage regulator:(.

So I am guessing P5Q Deluxe would be the superior board in terms of overclocking Q6600 :( although I still have yet to over clock my Q6600 to 3.4-3.6GHz .

Nope the gigabyte is the better board for the Q6600, I know on paper the P5Q deluxe seems a better board but its not.

It is very very close though.

Gigabyte boards rock

UP45 UD3P CLICK ME

Not quite your board but its the only link I had with a gigabyte board
ALL KUDOS TO NOGURU FOR THE OVER CLOCK I COULDN'T CATCH

Wow:eek:. Thats insane. Q6600 @ almost 4.9GHz on Gigabyte GA-EP45-UD3P. That's insane. How did he achieve it? Did he use liquid nitrogen? Yeah afaik the GA-EP45-UD3LR is same as GA-EP45-UD3P in core functionality with few differences in features. :).
 
dont think he used LN2, just pushed the boat out for a suicide run, @ 1.7v my water can keep it well below 70c@ load just cant find a chip good enough

I could be wrong he might have been on dice just dont think so, I got 4.3GHz @ 1.63v but at 1.7v I could only get 4.3GHz just the chip I think.
Even at those speeds 4.5GHz< your running PLL voltage @1.8 and thats just plain not safe

Hi guys back again :).

I have just recently bought Thermalright IFX-14 along with 2x Akasa Viper 120mm fans and MX-4 thermal paste as stated in my previous posts. Somehow the cooler was slightly narrower at one end compared to the other end. Here are the pics of the cooler in my HAF 922 case:

Pics of [email protected] (prime95 stable) to follow very shortly:).
 
Although it has been very cold and snowing outside but inside the home it has been very nice and warm with radiators running hence the idle temps reaching generally in mid to high 30s degree celcius already:). The cooler has proved to be excellent with akasa vipers fans attached to it for [email protected]. However the only downside is that my Gigabyte P45 mobo has a high collective 'Vdrop/Vdroop' of 0.1v:(. I ran the Prime 95 small FFTs stress test for 10.5 hours and it was rock stable. These were the following voltages for [email protected]:

Bios Vcore: 1.41250v
Idle voltage: 1.360v
Load voltage: 1.312v


[email protected] Idle

[email protected] Load

q660034ghzloadbiosvcore.png



The load temps were very good although I have noticed that core 2 and 3 run few degrees cooler than core0 and 1 and there is generally always 6-8C difference between core 0 and core 2. I suspect that core 0 + core 1 form one chip and core2+core3 form the 2nd chip as Q6600 consists of 2 E6600s joined together rather than being a 'true' quadcore so one chip may well run few degrees hotter. This is again my speculation and I could be wrong.

Coming back to the issue of large vdrop/vdroop; I have been reading easyrider's Q6600 overclocking thread:

http://forums.overclockers.co.uk/showthread.php?t=17757702&page=69

In the post 2065, setter's Q6600 had a slightly higher VID of 1.2750v compared to mine's 1.2625v. However for the same bios vcore of 1.4125v he had [email protected] prime stable as his load voltage was 1.416v compared to mine's 1.312v:( although he is using a different mobo. Is there any way of reducing vdrop/vdroop? I have heard of pencil mod but not sure how to apply it exactly.

All the comments/opinions are welcome:). I have achieved my original goal of [email protected]:). However I have been running Gigabyte 'Energy Saver' utility and noticed that for [email protected] and 3.4GHz at idle, the cpu power usage is 17w and 34w respectively. So cpu power consumption seems to have doubled :eek:. Would this have much effect on my electricity bills?

Lastly I am planning to push my Q6600 to 3.6GHz although I don't plan to run at such speed for a forseeable future though it would be interesting what voltages and temps I get considering my mobo has large vdrop/vdroop. Any more suggestions guys?

Many thanks :).
 
Expect an easy 3.6GHz+ under that cooler, 1.350v under load will see around 65c per core at a guess, which is still more than safe :)

Looking good Wingman :D

Any reason why you aren't going for 3.6Ghz?

Haha bainbridge aka Gareth to who I sent the link to akasa viper fans:). I looked at your thread about meghalems with akasa viper fans and I am glad you reached 3.6GHz on your Q6600. What were your voltages including bios vcore and did you up the northbridge (MCH) voltage?:)

How much does bios vcore matter if the load voltage is around 1.350v as you mentioned? So hypothetically if bios vcore was 1.55v and load voltage was 1.35-1.37v, will bios vcore degrade the cpu life/performance?

I'd be suprised if you need anywhere near 1.500v BIOS for 3.6ghz stable. To give you an idea my former Q6600 managed 3.7ghz with around 1.4v under load, and brothers Q6600 is 3.6ghz stable with only 1.360v.

I see what you mean. It's just that I always experience around 0.1v of collective vdrop/vdroop on my mobo. So whatever bios vcore I enter, my load voltage is always around 0.1v less than bios vcore. So if I set bios vcore to 1.40v, my load voltage will most likely be around 1.30v.

For a load voltage of 1.350v, I am pretty sure I will end up with bios vcore of 1.45+v unless I can reduce it somehow with pencil mod.
 
Trying to get mine stable at 3.8ghz, temps hit 73c under load @ 1.4v but is stable for 5 hours under prime95.

Just tried 1.375v and it failed after about an hour, trying 1.384v now.

My Vid is 1.2v and using Megahalems and 2 viper fans for cooling on Asus P5Q deluxe.
 
So I take it that out of the three voltages: bios vcore, idle voltage and load voltage, the load voltage is the most impotant one to look at?

Yeah thanks for your help mate, purring along at 3.6Ghz as I type :)

Had to go right up to 1.5v (1.5075 in BIOS) to run stable at 400x9 under load, anything below this would result in a crash, though I was able to boot to windows @ 3.6Ghz from 1.45v, anything below this would BSOD after posting.

Regarding the Northbridge all that was needed was a 1 increment nudge up in voltage from the default 1.25v to 1.33v. Before I did this I was unable to get stable under load with the clockspeed above 370mhz on a x9 multiplier.
