ill tell you what,

if you want to bring it to the shop then i will clock it as high as it will go :)

ill need a few hours with it, but dont mind seeing as you have done such a good job

email my trust if you are interested :)

[will have to be after the end of the month as we are really busy at the moment]

You definitely can't argue with that. Top service there :)

gonna have to wait a little longer for some pics, camera is charging but will get some up soon i promise.

just to recall the setup:

i7 920 D0 o/c 3.8mhz
asus 5870 std clocks

cpu and gpu watercooled as in thread, and rad has now got 3 apache blacks blowing air out of the case via the roof of the corsair 800D

1 apache black conected to rear of case blowing out
2 noctua (dont remember the models) drawing air in from the bottom of the case, and a couple of no name fans cooling the SSD and 1tb HDD

these are all backed off to almost silent using the fan controller.

my idle temp for the cpu is 39 , havent ran prime yet .. dunno how long to let the cooling "bed in" ?
after playing ten mins of bad company 2 , temps increased to 49/51.

gpu idles at 31, rises to around 48 max after 10 mins of bad company.

do these temps sound about right? not sure if ive tightened the cpu enough ?

Nice underclock. ;)
 
although rjkoniell has kindly offered to overclock my system , i thought id be a man and give it another go myself too.
(afterall i really want the satisfaction of "getting there" myself if i can )

well, im happy to report that im now sitting at 4 GHZ :)

all settings remained the same as in my 3.8 overclock , except instead of running at 190x20 , its now at 200x20.
i had previously tried this when not underwater, but it would just fail prime in less than 10 mins.
could it have been the fact that my old noctua heatsink and H50 wasnt up to it but now on water and a lot cooler made all the difference?

temps on full load was 62 , idles around 42.

so what do you guys think?
 
I was jealous of the free offer but really the most satisfaction is in doing it yourself so good job !
Desperate for my bitspower fittings to arrive so I can get fiddling.
I went straight to 4.2 when I had my first loop working but havent tested properly yet.
I will be happy with 4 if it runs quiet.

having to work just gets in the way
 
sounds good. chances are it needs a bit of tweaking on the voltages.

im going to aim for 4.2ghz when you bring it in. basically because you dont want the cpu hammering heat into the loop. the problem you have is that anything past 4.2ghz usually requires a big vcore boost. this is a problem in two respects.
firstly because you will have to use the top end multi which usually requires a little more vcore, if the bclk gets increased past 200 then your memory will either be running beyond rated speeds or massively underclocked on the lower divider.
secondly the higher multi generally requires a little more on the vcore and more vcore generally means much more heat.

20X200 is generally the sweet spot [although some gigabyte boards prefer 21X191] as it means two things.
it takes turbo mode out of the equation and also gives rounded memory dividers [1600 & 2000] obviously putting the multi at 21 takes it to 4.2 but it keeps the bclk at 200 and means your cpu will run at a higher clock without the bclk increase pushing the rest of the components past rated speeds.

[sorry if none of that makes sense, i know what im doing... honest :p]

some of it did .. ok, most of it didnt :p
...and for that reason, ill leave it in your capable hands ;)

cya soon buddy :cool:

Saw on the first post you used cable ties, would Jubilee clips not be better to ensure there are no leaks?
Click to expand...

to be honest, i tried both , but i prefered using cable ties in the end.
i dont think theres much between them personaly, other than ties being cheaper.
i also liked the neatness of the ties than using clips.

... believe me, i gave them tubes a fair old pull, they wasnt going anywhere ;)
