Since yesterday, I've been fooling around with some dry ice (DI) and a pair of chilly1 DI containers. Here are some pictures and screenshot of what happened



The money shot


Ice cold coke in less than 30 minutes


The key to a successful sub-zero cooling is the insulation so I started by coating the back of the motherboard around the processor socket with some liquid electrical tape.


The same thing was also done to the front and back of the graphics card



Next I applied some foam insulation tape on both the front and back of the motherboard and graphics card.

After all the work insulating the graphics card, there was some problem with the mountings. Due to the rapid dwindling of my DI supply, I decided not to waste anymore time fixing it and went ahead benching with DI only on the processor.

After I'm done benching there were some DI left and here's what I did with them

DI + hot water + soap


DI in the toilet bowl

awww, c'mon arj you didn't do us justice!!! what's the cpu temp!!, i wanna know wheter the sub zero bugs with the venice has finally been sorted.

By the way.. WOOOWWWW man 3GHz !!!!:thumbs: congrats,

O.T.: now i've got the chill to take a crap in the toilet bowl

having fun i see

so when ru trying on the dfi and some xtreme ln2?




also...the liquid electrical tape (red goo) can peel off/remove once ur done?

I was rushing just now because there's only a few block of DI left, forgot to stick one of the thermocouple on the base of the DI container

The bug is still there but you don't have to worry about it unless you have a tripple cascade.



Kinda lazy to take out the DFI from the case, clean up the dielectric grease and them put it back in the case

No LN2 for me, too risky




A'ah, dah ada rancangan

so that brush on electrical tape.. does it just come off by peeling?

Yup, peels off very easily

Yup i second that, , tried and tested.. no need other solvent or chemical.

LN2 not only dangerous to u but it kills the proc and mobo efficiently also..
Arj if im not mistaken, DI wouldnt be enough to cause ice to occur all over the mobo..So with proper insulation like master arj just shown us here..Ur hardware is quite safe..

Haiya i got slow streamyx connection today, some pics dont show up..
Im dissapointed..

Btw, congrats 3.2Ghz is just awesome..
Lookin at those step by step pics, it motivates me to put my winnie under that DI..

I know winnie had subzero bug, but u might never know..

Hmm but those containers, How much u got them for..
and all those stuff such as electrical tape can be obtained from normal hardware shop?

Both of the containers costs more than the processor

Yeah, they all can be found at good hardware store like Ace Hardware.

// arj : do you DI your vga card as well???

Evogenix

Nope, not this time.

Tripple? woaaa... we're talking more than -30C here..., well than i guess the bug is partly sorted.

yeah PCcrazy, you'll never know unless you've tried.. neway can tell me where can get those liquid nitros? Need special license or permit to get hold of em?

LN2, im not sure cos normally its not accesible to consumers..
Its just like all those acids and chemical stuffs..
If u happen to know somebody working at science lab, i think this might come handy..
Hmm, maybe i jus give my buddy a call and try asking if he could get his hands on LN2..

some funny thoughts to share..

Dry Ice Obligatory Warning
Madshrimps ©

Carbon dioxide is heavier than air and it can concentrate in low areas or in enclosed spaces (like a car or a room where dry ice is sublimating). Normal air is 78% Nitrogen, 21% Oxygen and only 0.035% Carbon Dioxide. If the concentration of carbon dioxide in the air rises above 5%, carbon dioxide can become toxic.

Arj, u sure u r not toxicated
Any clue where did u get those big blocks of DI..

Three stage cascade can easily do -100. The cold bug is around -90 if I'm not mistaken



Damn.... I'm having a terrible hangover right now

I bought the dry ice for RM3.80 per kg from a place in Shah Alam, somewhere behind the aquatic center. I got their contacts from Baskin Robins

erkkkkk more than -100C!! the most i can dare is a single phase system.. temp around -25C~-30C.. .. even Fugger's dual stage cascade scares the sh@t out of me (-100C!!).. sigh.. i wish bulkhy can come out of retirement and help me out on this one , neway this is after all about D.I... a little bit off topic ere..so arj wanna start a sub zero club? Anything that can cool below freezing point can discuss and shared with all LYN's own Xtreme Cooling!!! yeah

ON TOPIC: CO2 is poisoneous if the concentration level reaches 5%, symptoms of CO2 poisoning after prolong exposure to a highly concentrated CO2 environment are:

1. Drowsiness
2. Vomitting
3. Discoloration of lips & fingertips
4. Morning sickness (mebbe i've got mixed up with this one, is it pregnancy or poisoning )

Remedy, rest in a good ventilated room for 12~16 hrs taking plenty of fluids. If symptoms still exist, go find a bomoh.

how long does the dry ice last before it evaporates..

That's the three stage cascade
http://www.xtremesystems.org/forums/showthread.php?t=44089



A block of around 250g can last about an hour if you just leave it alone outside the icebox. You can bench for around 7-8 hours with 10kg of DI

10kg D.I. how much the cost ar?

Oh thank you for showing the link, sorry, the dual cascade that i meant wasn't fugger's, its this oneVR-Zone DIY Dual Cascade Vapour (they got help form Chill1 and the crew).. .. yup i'm into diy'ing my own phase cooler (slowly.. very-very slowly ).. wish me luck.

MOX sells liquid nitrogen, called just now for fun saying i need some ln2 for experiments. they have sales centres throughout msia - http://mox.com.my/contact_us/mox_sales.htm

they dont rent out dewars (container) so must buy it from them...sizes are 4L or 10L

they said will fax me a quote for the price of dewar and ln2 so dunno the actual price

better read this before playing with ln2...

I got it for RM3.80 per kg.

Good luck on your project!

1st stage phase change with R22 gas normally can hit around -40C to -50C. Well, it also depends on gas that is being used. And depends on the compressor too. Bulkhy's xillixx able to drop around -47C. Lotsa things need to be done to get a very good phase change systems. Need able to handle load the most efficient. Anyway, a triple stage would cost triple arms and legs. R507, R404 are hell expensive. Expect more than RM500. Bulkhy used to have a plan on building cascade. But he has better things to do, his career. Btw, I'm sure Bulkhy willing to help you out dude. Good luck!

Still, for short bench. DI and LN2 is the best. Since Winnie/Venice has bugs on subzero temp, DI is the best. So arj, you have hit your wall or you need more DI?

incressment of 77.78% from dafault clock
the result just same like the old days 2.4C from intel that able to clock to 4.2GHz

Evogenix

Hey thanks a lot man.. i think i'll give them a call next week!! It's not for the rig project by the way.



Sorry arj, had to tumpang your thread again.. yes c9, bulkhy did told me he's willing to help, in fact he even promise a return to the xtreme cooling club .. , Your xillixx still up and running? I'm not ready for cascading yet, mebbe try out the 1st stage phase first.. one refrigerant equipments and parts supplier in melaka can help me out getting the parts and labour for the kit.. right now still sketching and calculating .. thank you for the info man/maam.. nice butt by the way, yours ?

Note on LN2: Please be extremely careful if you do LN2 experiments. A friend of mine who works for MOX told me one incident with their client. They spilt LN2 on the road but didn't clean it up. A dog came along and licked the LN2. Dog didn't realize what happened until a short while...and then its tongue just broke off and the dog squealed like there was no tommorrow.

Guys...LN2 accidents can happen to us too...and it is NOT funny. You will be utterly horrified for life if you lose your limbs or even part of it...just because you wanted to bench using LN2...

Ouch! Pity the dog....

As I said before, I won't be benching with LN2 anytime soon due to the huge risks involved. Having said that, if you completely understand the process and take proper precautions, I don't see any reason why we shouldn't do it.

aiman...u crazy fella la...pity the proc la...haih.....btw...can the proc run at -100C ?? jz wondering la...

good luck in ur future oc....btw..when m i seeing u for the z5500??

cant wait for it ady.....

amok: Glad to hear that. I would wanna see another extreme cooling expert around here. Anyway, I have retired already. Overclocking seems never ends, wasted lots and lotsa money. My xillixx is in Bulkhy's hand for some mod. Keep us updated dude.

arj: Gud luck!!

For those wanna know more bout what arj is actually doing, this would be a good start

http://www.madshrimps.be/?action=gethowto&howtoID=59

To summarize the contents:
1. Background of DI, what is it? why use it?
2. A little bit info bout the container..
3. Insulation techniques, very similar to what arj did..
4. And the fun

Ever wonder how DI is manufactured..
http://www.dryiceinfo.com/mfn.htm

So, enjoy..
Maybe next time, we will see you doing DI benches..
It looks easy to setup, but believe me you will run into all sorts of problem..

Now since u all have read the above given links..
Here comes the quiz for today. Why they call it DI?

Btw, Amok you have my support..
Go for it dude, you have the skills..

aiyah don't retire yet lar... , i'm in the process of persuading bulkhy to come out of retirement now you pulak wanna retire

arj: yes try the LN , it'll be m'sia first!! but please has some one around to help you out man..

PCcrazy: hehehe, yes mr. encyclopedia , i'm sorting out with bulkhy currently, and the soonest mebbe by next month come lar join phase cooling, i'll bet it'll be more addictive than watercooling..

thank you for the support from ya all.

Check out this DI run by the pros ----> http://www.muropaketti.com/3dmark/

aww.. asus 6800u SLI
they have the 2nd rank in HoF

Evogenix

instant contact to liquid nitrogen -> instant frostbite worr..you all want to play with you life possibly arh?

Use gloves lor...
here's a link of the dudes at vrzone playing with ln2.

http://www.vr-zone.com.sg/Shamino/ln2video.wmv

i like the broken beancurd.

what will happen if accidently the container drop to the our body
is there any fast aid to do if it accident contact with our hand

Non prolonged contact with Dry Ice is okay...
It is not hazardous or fatal compare to Liqiud Nitrogen...
LN2 instantaneouss effect is very dangerous...

I got a feeling that DI round 2 is about time

I had to second that.. come on round 2 , now that the SLi is in place

I had another DI run last night, this time with the FX-55 and got stuck at the 3Ghz mark again! I really don't know what the problem is and I've double checked everything. The contact is good, insulation is good, and I have enough vcore.....

Its not good to hear that arj, isnt it a possibility that the culprit was your memory controller. I have notice some forumers at XS lamenting their new FX-55 wouldnt go past some point jus because of that bug.

But no worry, your venice did well though...
Btw this DI test, run on DFI or MSI?

I used my NEO2 for both DI runs. I don't think the memory controller is the culprit because used high multipliers and low HTT.....

Yeah, the FX-55 is not locked upwards
So you can totally eliminate memory out of equations.

Hmm, I got a feeling the 'Clawhammer' CAA2C's would be able to clock higher than what the FX-55 can with sub-zero cooling. That would be an interesting test I believe

auwww... 3GHz on a FX-55 is overwhelming ledi... i'm interested to know the max you can get with the venice with DI .. round 3 perhaps?

On DFI SLI-DR this time around.
With two SLI'ed ultras just can't wait for 3dmark scores to be released.
De_Cruelz and arj are pretty much the king here right now.

i feel proud our lowyat.net also got a hardcore forumer like arj... it proves that malaysian people are not too far behind they people in the west..

I think it's actually cheaper for Westerner to dwelve into crazy overclocking and modding stuff. In general I think it's much more affordable to get parts and hardware overseas as standard of living is high. If I was living in Msia now earning RM I can only dream of building a A64 and whatmore SLI rig

This is what I think: For a Malaysian, a simple, tasty and filling meal will at most cost roughly RM10 a meal including a drink. Let's say to purchase some OCZ value VX ram locally will set you back about RM600 (just a rough currency conversion).

In Australia, a more than filling good quality meal with a drink will also set you back AUD10 on average. However, for me to purchase that similar OCZ ram is AUD170 here! In other words, I would have to save money much much longer before I can get to purchase those OCZ sticks if I were living in Malaysia and earning in RM

Food is cheap and standard of living is low in Malaysia. Factoring out currency exchange, there's a huge gap compared to Australia. If i'm not wrong, Sydney, Australia is ranked the 3rd highest standard of living in the world.
---------------------------------------------------------------------

Back on topic, i'm eagerly awaiting some results from arj. He's gonna be my main contender for the 3DMark Hall of Fame . This is gonna be interesting

[OFF TOPIC]
You've got a point there De_Cruelz. My sis and few of my Aussie friends makes thousands of dollar easily there...De_Cruelz, UNSW?

Back on topic, How is the overclocking progress of those 6800gt...
Is the waterblocks ready yet.

My waterblocks haven't arrived yet, still waiting for it

PCcrazy, yeap I couldn't agree more. I myself have earned at least 2k AUD doing several days worth of design work. Skilled workforce get paid good money here mate

I'm currently waiting for the Maze4 SLI blocks to arrive in Australia. Suppliers told me it should be here by the end of the month. Don't know how accurate is that though.

arj, what blocks did you order? Did you get the NV6800 or the Maze4's too? I think the Maze4's would perform better with higher flowrates and cooling efficiency. The NV6800's seem to be quite restrictive unless you run a separate loop with its own pump. Care to update us on what your upcoming SLI cooling system is gonna be like?

I ordered the Maze4 GPU, wanted to get the NV6800 but decided not to because quite a number of it's users reported problems when using it. As for the watercooling system, I have a Black Ice Extreme 2 radiator MCP650/Eheim 1250 pump and a DD TDX. I might run the GPU blocks and the CPU blocks in one loop or two separate loops if the temp goes up too high.
