Dice/Acetone Ghetto cpu/x1800xt, trying for the record....

Hey all,
Figured I would try a dry ice and acetone chiller setup, totally ghetto mind you.

Here are the goodies I'm using for this project:

http://aycu10.webshots.com/image/259...0976735_rs.jpg
Gallon acetone
Fancy pot
10 feet copper tubing
Ghetto res
Dtek Mag pump
1.5 to 12 volt variable supply for the pump
Zalman water block from a old water cooling setup
Lots of silicone 3/8 tubing - stays soft and supple even under extreme temps
Aquarium thermometer - digital - reads to -50c


Here is the cpu, Opty 165 taped up and in the socket:

Here she is all assembled and leak testing:

Now time to go buy 20 pounds of dry ice...


Fill up the pot with dice:

According to probe taped to copper tubing temp is 1.5c
Cpu = 18c
Gpu = 23c
My first run of 3dmark05 goes good, 11819. So I up the core and mem.
Core 820
Mem 1010
Cpu at this point is runnning 3099mhz 1.65 volts rock stable.
Another run of 05 at these settings give me 12257. Not bad at all. So I try to up gpu core to 850, system locks up. Not cold enough.


Here is the pic of system with just dry ice in the pot after 40mins of testing:

But I have to get it colder. Time to add acetone to the dice pot. Slowly pour in about 2 cups of acetone. Now things are getting colder!!!

Here is the cpu and pump pics 10 minutes after adding acetone to dice:

Temps have dropped like GW's approval rating.
cpu -35c
gpu -46c
The temps are just too cold for the gpu. Screen goes all jittery on me and then locks up.

Thats when I try adjusting pump voltage to control temps. Drop it to 6 volts, still too cold for gpu. End up dropping pump volts to 1.5 to get back into windows.

Good temps for gpu hovering around -25c. Time to break out Clockgen and set cpu to 3099. Hit the set values button and the system locks up. What a time for this to happen!!!

Do a hard reset, passes bios screen no problem, goes to read hard drive and nothing. After an hour of fiddling around I realize my windows install is borked! Man i'm ticked off! Just 300 point away from world record. I was super confident it would happen too.

One thing I learned is to be careful with adding acetone to dry ice. I couldn't believe the temperature drop. Unfortunately I didn't upload my 12257 05 score, thought for sure I would get the record. Gives me a new found respect for the hard work involved in putting up scores like that.

So time to wait for another day....

thast an insane setup. sorry to hear about the badnews though. you should probably insulate your stuff, or you might end up with a dead card. but man, i never woulda though of doing anything like that. very creative!

Pretty ghetto, good stuff man, temps are mad.

:o amazing stuff

sorry to hear about your os loss, but your setup looks sweet, bring windows back to life and go for the single card WR!

You got guts man--That card isnt gonna last long in that setup, I would insulate or put a drip guard in over it :/ . I never seen a chip taped up like that before.
Good luck with your record(s) :toast:

i see u have your KM in the pic see u on wed :-)

Pretty cool, hope you will get some record(s) for the hard work you did.

easy way 2 subzero cpu&gpu :hehe: . i like it :)

very nice, i might try that on my gfx card. What liquid was running through the tubing?

I say do it anyway for safety's sake. That is a lot of money there.

OH....NICE! I`m well impressed with that!!

As above...what was your coolant?

Did you not have any hassles with the pump from the low running temps?
How you gonna deal with the condensation?

KEEP GOING!!!!!!


Kenny

I was running acetone through the loop. Pretested the pump to make sure it could handle the cold and the acetone. Tried using a cheap pond pump and the acetone melted it.

Yes condensation is a issue at the moment...

Lol, I go on thursday bro.

PM me and we can chat...

True but I wouldn't risk it as personally I am broke hehe.

As for temps on the gpu maybe try loosening the mounting screws or adding some shims inbetween the core and wb.

After your experiences do you think a D5 would be able to handle the same/similar setup? I really have been looking into doing this, but wasnt sure if the pump could handle it.

^^

Under volt it! ended up running mine at 1.5 - 3 volts to slow down flow...

pretty nice idea . is that a AMS genesis that it is all in too?

^^
Lol, yup the $23 dollar special from the Egg. Best case for the $$$ imho...

Nice and Frosty oh and Ghetto. :D

On a side note, getting around the cold bugs on the cpu and gpu is quite the task. I had to use A64 tweaker to lower mem ratio and clockgen to set fsb, bios simply would not allow it. Makes going for gusto much more difficult.

Gpu cold bugged like a mad man. Once temps hit -20's I was left with a very small time frame to up the volts with AtiTool. Setting volts for core higher helped with gpu cold bug. Need a bios tool so I can set higher volts permanent for benching.

woah nice i would of maybe put something over the back of video card in case droplets dripped on video card ???

Awesome Setup!
Good luck with future experiments.

very nice

Nice beching on dryice :)

Very nice project :)

Well fellas, this is the best I have done so far with my ghetto chiller:

http://service.futuremark.com/compare?3dm05=1686680 :D :D :D


Not bad at all, I must say...

Damn nice score :cool:

I'm surprised the pump can live with acetone. So what core temps can you run on GPU now? Have you tried upping core voltages and then adding the acetone?

Nice results Ply:clap::clap: Ghetto but quite Xtreme!!:D

But the cpu could'nt go any higher with the extra cold?

She bugged hard on me. I'm gonna need to do separate loops to break the record. Cpu can't take going below -17c...

Don't mean to revive an old thread, but I really liked ur technique... Do you have a current project like this again for your x1900? :)

Nah, my 1900 is a dud on the core, max 729 with water. Memory is really good though, 900+ with tweaking. Gonna wait till the next upgrade to play around some more...;)

Nice ghetto system m8 :)

What kind of voltages for 729?? Mine hits 675 max with 1.35, and won't even do 800 on the mem

1.575 core for 729...

Is there anything special to look out for in a pump that can handle acetone?
I was thinking of getting myself a pond pump for something similar :D

Has to do with the materials it is made from. I think the pond pump I tried was made from abs but not for sure on that. Got it from Lowe's Hardware store.

Delrin is fine with acetone, and I think Norel and Nylon is too but not certain on that.

Acetone likes to eat a lot of stuff so I would double check pumps materials before running acetone through it...

Ply i'm finally coming for ya http://www.xtremesystems.org/forums/...d.php?t=103927 :D

Very good.
I wait that you have not had any problem with the condensation, very valiant ;)

Lol, after seeing what you're "coming for me" with, I don't stand a chance. But may give yah a run just for kicks... ;)

I've used those cheap probes in chemistry. They are fairly accurate too. Only off by ~2c at temps of -5c actual.
If Acetone melts your plastic you can always try methanol too. It's available as automobile gas drying liquid (HEET). Be careful using HDPE Plastic under cold temps as it becomes very brittle and can crack easily if subject to impact. Delrin and nylon should be fine w/acetone but acetone will eventually eat through rubber o-rings. Acetone tends to soften even some of the toughest plastics after days of exposure. Methanol may be less abusive to o-rings. Acetone will really eat up any acrylics, polystyrene, PVC, and I think polycarbonates.

i like ur data scwam. ur oding chem r you?tis nice to tlak to osmeone in the know. im at uni oding a masters in chemistry and i ahve ofund it very useful in the extreme cooling world,:)

Thanks, unfortunately, my chemistry wasn't accredited by a college or even legal when I was doing it but I enjoyed the hell out of it. Especially having to know about what solvents go with what plastics. I found the whole precision of chemistry really fascinating, and see the results of my own work was rewarding. I remember one chem: P-benzoquinone, man that stuff is really nasty.

Thread necro here. Just updating the pics...


Ply

excellent Plywood99 i really enjoy seeing stuff like this.. gotta love your ghetto setup :up:

Thanks for posting the pics Ply. :toast:

this is great good on ya dude

love the setup

the only thing i am surprised people are still not insulating components and also waterloops and blocks >> you should probably do it to avoid killing it prematurely

Yeah insulating is always good advice. When I ran this loop it was really cold outside so I put a fan in the window and kept the room closed for several hours to reduce temps and humidity. Room had to be around 5c if not colder.

Doing such a thing in the summer would be murder.:eek: I'm sure she would have been dripping water after justa couple minutes...

P.S. Hopefully Amd will have something on the table to play with this winter. If not I'm movin to Penryn. Been loyal to Amd for a lonnng time, but I need to have some fun...


Ply

yak..:eek: good job it very nice, i'll try too :D

:rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :ROTF:

I thought you had dice and acetone? All I saw was dry ice and acetone? Ah well, thought it would been funny to sdee molten dice, but DRY ice is fun too.

Xeon, I've always wondered what a "lable" is? :confused:

Maybe he misread the lable and got a little confused...
