Watercooling = Wow

[Pilky01]

My q6600 is a fairly lousy overclocker and with a tuniq tower the best I could manage was 3.2 stable, i tried for 3.4 but i need to use a lot of volts so the temps hit about 80c, i wanted a little more than this so i took the plunge and bought a pa120.2, d-tek fusion with quad nozzle and a liang ddc ultra with alphacool top of the member market.

It has knocked about 20c of my load temps and im currently testing at 3.6ghz with the temps at 60c. Only thing that concerns me is the amount of volts i am putting through it.

Thats a lot of volts for the clock... I'm not comfortable personally putting more than 1.5v through the 65nm chips for normal running...

Having said that I have a E6600 @ 3.825gig thats running 1.65v for almost 2 years no problem so far but I wouldn't do that with a chip I didn't want to risk replacing.

That's quite high, but if your comfortable putting that much through the chip, if not juts shoot for a clock around 3.4-3.5Ghz.

I needed 1.49 for 3.6Ghz on my Q6600 (vid 1.3) so those volts are ok. Wouldn't run them 24/7 though.

 

[Shaddow]

That seems a bit high.. I have my Q6000 @ 3.6ghz with Ultra 120 lapped @ 1.47v

Do you have the G0 chip?

 

[booyaka]

i'm like you with a G0 Q6600 but with a vid of 1.325v also - takes a mountain of voltage to get it above 3.2ghz.

I was struggling to get 3.2ghz under air but now under water got to 3.37ghz but still needing 1.525v to get there!!!

Wish i had a 1.175vid or something like that!!!

After installing WC on my Q6600 :

Q6600 @ 3.2GHz (9x356MHz, 1.4v)

CPU = 33c Idle and 44c load

So it does seem abit high to me still.

Thats a lot of volts for a 24/7 clock. Personally Id rather run at 3.4GHz and put 1.4v - 1.5v max through the chip. Your load temps should drop considerably too.

What he ^^ said.

Whats the point risking the life span of your cpu to gain 200mhz?

 

[Greebo]

Ditto on the voltage. My q6600 needs 1.55v under load to run at 3.8Ghz. I just use that for benchmarking.

24/7 use I am happy with 3.5Ghz at 1.35v (under load).

For surfing I just run at stock 2.4Ghz at just 1.1v ish.

 

[MoRT489]

Under water provided the temps are within intel's boundaries, then I dont see the problem with 24/7 running at 1.6v...

 

[benjo]

Mine needs a lot of voltage to get around those speeds, at the moment it's at 1.55v for 3.6, and mine is also water cooled.

Suicide run :

 

[waso_dude]

wow i feel for u guys.

3.6ghz wiht 1.4v 50degrees load temp

 

[booyaka]

wow i feel for u guys.

3.6ghz wiht 1.4v 50degrees load temp

gee - thanks for your concern!!!

Yeah but from 3.2 -> 3.6 you need ALLOT of volts. I think i was stable at 3Ghz on 1.3 (my vid) but needed almost 1.5 under water for 3.6Gz

Thats a lot of volts for a 24/7 clock. Personally Id rather run at 3.4GHz and put 1.4v - 1.5v max through the chip. Your load temps should drop considerably too.

The volts required is usually relative to the vid.

I don't think he was going for a 24/7 clock. Who keeps a CPU longer than a year anways

I do had this AMD 4400+ 939 CPU since they first came on the market
Unfortunatley some of us have very tight budgets and cant afford to be
upgradeing parts everytime something new hits the market. (wish i could though)
Maybe we should ask the OP if they are intending to run the system 24/7 once
clocked if so then he may want to back the clock down a bit to keep the system stable
and safe when running it 24/7 if he has to run such a high vid to get system to run at 3.6 Ghz

Yep agreed - i did imply this in one of my previous posts.

wow i feel for u guys.

3.6ghz wiht 1.4v 50degrees load temp

bit on the warm side

*wonders if its willy waving time yet?*

In answer to the OP have seen people run 1.55v+ for over a year as long as the load temps are sensible then I dont see an issue.. also if you are using power saving like speedstep or whatever on a non-asus board then it will drop the vcore as well..

I ran mine @ 1.5v at full load of months folding @ 3.8ghz and well its mostly alright still

As long as your temps and board volts are also sensible then I wouldnt worry to much

I have a question for the op. So you have raised the clock speed by 400mhz - How much did the total water cooling solution cost?

If you're getting to the point that it wasnt cost effective, he'll be able to use this same kit for many more processors to come
