Well so far on 4.13 ghz stable for 1 hour 30 mine prime95 @ 1.31 vcore

(cpuid) with themps highest 79 degress:D

Im hoping that temps will be roughly the same as how they went up with

the 4.0 overclock so hopefully they wont be increasing much if at all

but will let you know the outcome.

I also had a look and there is no database of overclocks for i7 930 on the

forums here. So after I get my maximum clock which im hoping for 4.2 I

will start a thread on overclocks for i7 930.

Least im getting some where now, till i see a bsod lol.

Cheers:cool:

start a new thread about overclock speeds and temps.

By the way, Rick , why have you only overclocked to 3.2?

I was gonna get that board but decided on rampage 2 extreme.

Wish I had gone with the gigabyte you got now.

Couldnt get 4.2 ghz as temps were too high.

So ive bought some mx-3 in the hope of gaining some degrees here and going

for the pea method of applying thermal.

If I manage to gain 5 degrees ill be really happy.

Hopefully in a months time I may be able to get another cpu block, currently

Swiftech apogee gtx and that should also help drop temps too. Not decided

which one to get yet.

Let ya know how it turns out with the mx-3 when I get it tomorrow<dance1>

Yeah its a really good board for overclocking.

I took my I7 to 4.3 then brought it back again because I didnt really need that extra horsepower for normal day to day stuff. Also because its a lot cooler now that it was then!

Yeah, let me know how the MX-3 does, although I would be suprised if it gave you 5 degrees!

The AS5 would have improved by a few degrees if you'd been patient and kept it for the 200 hour curing time recommended by Arctic Silver.

Regarding curing time, does that mean 200 hours before you turn on your computer, or just 200 hours of use, for it to settle in, before you should start judging temps?

Due to the unique carrier fluid used and the shapes and sizes of the thermally
conductive particles in Arctic Silver's thermal compounds it will take multiple
thermal cycles to achieve maximum particle to particle thermal conduction and
for the heatsink to metal cap interface to reach maximum conductivity. (This
period will be longer in a system without a fan on the heatsink.) On systems
measuring actual internal core temperatures via the CPU's internal diode, the
measured temperature will often drop slightly to significantly over this "break-in"
period. This break-in will occur during the normal use of the computer as long as
the computer is turned off from time to time and the interface is allowed to cool.

Break-In Period by Thermal Compound:
Arctic Silver 5:
Break-in period: 200 hours (Break-in period will occur during normal use.)
Temps will drop several degrees over the break-in period measured with a thermal
diode in the hottest part of the CPU core.

Thanks Jacka, I actually remember reading this now. Mine should be well cured by this stage lol.

and see if any difference.

I just wanted to clear up my point about my 5 degrees objective for you Ricky.

What I meant is Im hoping for a few degrees from either the curing of the Ac5 or

the new mx-3 im getting. Then Im hoping to gain another 3.7 to 4.0 by changing

from apogee gtz to apogee xt. So all in all this will be 5 degrees roughly.

Have a look at the temps difference on this review.

http://www.xtremesys...ad.php?t=253470

I will however have to wait a couple of months until I can afford to buy the apogee xt.

also thought of adding 2nd loop for the nb/sb and mosfets but that doesnt

make much sense to me. Under load the temps from the nb/sb dont pass 52

degrees so logically I cant see how having them in the loop can result in

higher temps for the loop when the highest temp in the loop is from the cpu

at 79 degrees odd. Any lets wait and see.

AC5? Also, I thought you said you had an Apogee GTX, not GTZ?

No worries underdog, I look forward to your results!

Easy Ricky, How is ya fella?

Ive managed to get to 4.2 (1.33v cupid) prime stable 3hrs + but that`s as far as

I can take it now. Temps were 85 degrees highest. Given curing on AC5 aint had

enuf time to take effect that aint too bad. I see some others under water have

got the same. But others on water have also got same clocks with far lower

temperatures and I`m struggling to understand why. Maybe the only thing they

have in their loop is the cpu, that is all I can think of.

When I eventually do a 2nd loop I will put ns/sb, mosfets and gcards all on

one loop and leave the cpu on a loop if its own and see how that does.

Not gonna bother for AC5 to cure. When mx-3 arrives tomorrow ill chuck it in

straight away. Seeing as mx-3 is supposed to be 2 degrees lower than AC5

and given the 2-3 degrees drop you should see after curing maybe I will be

able to get 5 degrees lower than now before replacing my cpu block in a

months time which will hopefully further reduce temps.

Here`s a database of i7 930`s ive found as a reference point for now until we

do our own : http://hardforum.com...d.php?t=1502931

And sorry Mr Jacka my mistake mate. I got a apogee gtz.
Thanks. -_-

reaseated and still crazy temps

even 3.8 ghz with 1.3 volts in cpuz has 88 degress + load temps.

nb/sb 50-52 degrees

do i just have a crap chip or what?

according to all reviews this chip should hit 4ghz under water cooled.

w/c res - pump - cpu - nb- sb -res. (1 loop) 360 rad thermochill pa.

looking to send back to seller to get replacement. whats the best way to go about this?

cheers.


post all your other voltages you've tweaked in bios so i can see them. as you know - every cpu is different, you might just have a bad one - or the batch might be a bad lot? u know the batch?

what fans are on the 120.3?

It doesn't matter what you water cool - it becomes extreme!
