My test system / NB, VGA chiller

[berkut]

Hi guys ^^


Ive just made a new system for future chilling the CPU, graphics card and chipset. It will be tripple evap but the cpu evap will have an option to be diconnected via a electromagnetic valve so when i use a cascade whole power will be putted on the graphics card / chipset

The system is made out of a 22x22x11cm condenser cooled now with a 120mm, 107cfm fanwich will be replaced with a 17-20cm unit (the 120mm is to small during pull down, pressures go up to like 200 psi) and normal operation pressures are ~150psi (non loaded)

I use my standart flex hose (2m long, ~7mm ID) wich will be used in my cascade (thats why theres "My test system" in the topic), currently theres 220cm of 0.028" cap tube, 2m inside my flex hose and evap ^^

The evap is now some crap hollow i made just to connect it, later ill use a better hollow unit wich will be used as a northbrige evap and tomorrow ill post some loaded temps with the northbrge evap on the cpu.

The compressor is a 10000btu/h Tecumesh RK5510, got it yesterday for free beacause one guy saw my work and ill probably have more compressors like these so ill make some more projects like this one ^^

Some pics of the test system; the compressor i will use in the II stage used as a vacuum pump

A far pic of the rig

[berkut]

The isolation on the hose is 2cm thick

[berkut]

The compressor and condenser

Tomorrow ill post some real data + how does it perform, right now im really tired

It ran @ a ~ -0.6 - 0.8bar vacuum even when overfilled so it begged for some load

[Marci]

phuck me!

[afireinside]

:stick:

Is it tommorow yet?

[Major]

berkut you can't play with your computer until you clean your room !!! :D

[afireinside]

Whats with the tube (suction line, right?) running all the way accoross the unit above the whole thing? Is it the golden insulated gate to all your CDs or something?

[FUGGER]

What gas you running?

[Gary Lloyd]

That green jug in the picture is R22.

[ellsworth]

lol that is a long suction line, and a nice compressor :D

[sjohnson]

I want two, so the help can clean one whilst I'm using the other :D :slobber:

If you wanna know its cleaned :D:D Ive cleaned it for 2 days to get all those parts (for my cascade and my parents to drive me to this guy wich gave me the compressor), you can also see a vacuum cleaner deeper in the room

Its simply so long (2m long) its normally for the cascade (its so damn big it has to lay on the ground)


Is it tommorow yet?

Yea i just woke up ^^


I gotta eat breakfast, and than i can make a evap (its for the northbrige but will server nicelly as a cpu evap untill i get my new flex hoses)



What gas you running?

Yes, Gary is right, R22

Berkut what are you using as your lowside refigerant on your cascade? I found some ethylene today at work, for my future project. Need to find a better compressor first though.

]JR[

[berkut]

Tested the system today, now gotta make some isolation on the evap and make the mounting system better.

On a 2.5ghz barton @ 1.8V i had -12C core temps (didnt calibrate the system, just filled it up so the evap is cool :P, dunno evaps tempertures, ill know them ~tomorrow when i finish the mounting system

[berkut]

The low pressure gauge actually shows <-60C pressures/ temps but the pic was taken from a bad angle

Here are 2 shots of the system working

[berkut]

And a 2 pic

[berkut]

Making the "cooling head" ala prommie ^^ the only similar thing is the looks ^^

The white thing is poliurethane or pcv glue and its there to stick the evap to the wood so it wont move

[xxORBxx]

:slobber: Thats awesome. Did i miss you saying the temps or did u not? Has to be pretty good with all the frost :D

Nice work mate

[berkut]

This will be only a chipset / graphics cooler ;] The cascade will take care of the cpu ^^

Wonder how far will my crap barton go

[WxChaser]

It's great having all these mad scientists here - impressive as usual Berkut. Even if half the words you use confuse me, lol! :-)

[bowman1964]

what can i say........COPY CAT...LOL:D

serious....looks good buddy.:D

you allways bitting my heals..........:D

just be careful.....you are trying a few things that are not going to work to easy.

did you ever get the condensor leak fixed?:p:

later....keep it up.

[berkut]

Why copycat :P The same needs, the same tools, the same materials :o

Im using a cap tube only in the test system, ill use ford escort start up injectors in the full project ^^ Calibrating the system will be much easyer, simply set a bunch of clock gens

The condenser i use here doesent leak (at least i think it doesent), its from my old phase change

[Bra!nFreeZe^]

Berkut,what else can i say than impressive as always! :) keep up the good work

[berkut]

i went so far from 2.3ghz max on air @ 1.85V to 2.5ghz 1.8V


and i noticed one thing - the whole power for the cpu went through one cable on the 12V atx plux :slobber: i didnt have the aux 12V connected :slobber:

[berkut]

Ok, more info and pics ^^

The system:

[berkut]

Insulation finished

[berkut]

Well, not exacly, i gotta insulate the flex hose some more

[berkut]

Close up on the chipset, ram (made a vmod so it can go up to 3.3Vddr) and some mosfet cooling visible

A little note- i use a 8rda3+, the mosfets dont have any sinks and this mobo has no Vcore mod (no shutoff mod), and running nice @ 2.6ghz 1.92V (now testing @ 2.65ghz 1.97V but the system has to unfreeze, theres some damn water in it and i dont want to loose freon on a tripple evac so ill w8 till tomorrow to se if it leaks again)

[berkut]

Ok, and a screenie, its from 2.6ghz almost full load (with F@H in the background), temps with prime95 go only 1C up

For some reason i cant upload the 3dmark 2k1 score (18200) beacause orb says my cpu clock want the same all the time (???)

[Pimpsho]

disable cpu idle its stock settin is 50% if i remeber correctly on those epox boards...that should work..
~pimpsho

[bowman1964]

yea if you have the cpu streched to the limit...you have those problems with the ORB sometimes..

see if you can increase the voltage some.it may stablize it some.
what happens is the program scans the mhz of the cpu thoughout the bench....if it sees a change in cpu speed it thinks you are trying to cheat.
but another small problem that maybe hurting you...epox nforce.allthough i believe in epox nforce boards.they have a flaky clock generator that 3d2001 just doenst like sometimes.
you know how many top scores i had when i was benching alot that would have put me #1 amd,,,and the ORB wouldnt publish because of that small problem...

you have just entered the real benching world of problems...

[Major]

Berkut ! I told you that you couldn't play with you computer thingy until after you cleaned up your room ! Have you done your homework yet ? taken out the trash ? I didn't think so ! :D

[Popcicle]

..... young man i admire your talent.

The cpu isnt stressed to the max, i could run it @ 2.65ghz untill my system said "nada" and freezed :\ God damn leaks and not good vaccumed system...

Overclocking is cheating :D:D:D I know that but the cpu had some more power so it must be smth. else

All nForce boards have the same clock gens, its in the nforce itself

i can imagine :slobber:


you have just entered the real benching world of problems...

and its fun ^^

[Pimpsho]

wow that looks a bit chilly...what kinda temps u gettin

[berkut]

http://www.berkut.neostrada.pl/19k.jpg

The Geforce FX 5800 is NOT overclocked (uts like a ultra @ 500/1000), with 570/1140 i get 153fps in nature but its about the only test this computer wants to run :\ Have to mod my antec 480W

[Pimpsho]

wow thats nice man! going for a 20k run soon i hope;)

[JCviggen]

that issue with "CPU speed variation" on the ORB is usually because of your memory timings used. instead of using 2-2-2-4 for example, try 2-2-2-5 or 2-2-2-6.

Also, the clock generator is different depending on which board you have, ABIT uses a different one than EPoX, but the clock generator isnt really involved in this. I've soft-FSB'd my CPU's as much as 100 MHz lower and higher in between 3Dmark 2001 tests and it doesnt give me any crap about CPU speed variation. its a memory timing issue :)

[Pimpsho]

i think ill take your advice on that one;) but what if u had like 2-2-2-4 and then went like 2-3-2-4? or something i guess it all deppends...whatever give u the best timing...and score..

[berkut]

i use 2-3-3-8, my life's not easy :\

I heard that the bigger the last value the bigger the 3dmrk score (i cant touch first three cause these are already the tightest timings)

[Pimpsho]

what kinda ram u using?

then you need some winbond BH-5 my friend ;)

using lower FSB with higher multi would also help. you might be able to tighten up the timings then too.

On an NF7 I found "11" to be the fastest timing for that last one, but on the EPoX board 4 or 5 was best.

[berkut]

Hehe, if i had money i would buy bh5 chips ^^

Lowering the fsb for tighter timings means going down to like 150-170mhz fsb... dont think its worth it

ill go the other way - if i cant lower the timings ill push the fsb, all the way to 245 (know the rams can cut it @ 2-3-3-8)
