lol, you sound like me. i've been pushing my gfx-vmod around. first i was waiting for the right block, which got delivered dec 24, then i was missing the pumps and the tubes.. (still missing the tubes) and now it's some fittings and neoprene.. doh.
anyway. i've the complete vmod prepared, all soldered together, pots (cermets?) plus dipswitches to turn the individual mods of, fixed points to get the current voltages and the current resitance of the pots... all in place. just need to solder the 7 cableends to the acutal gfx-card ;). don't want to blow it while still air-cooling it ;)

now do it! you got the rig and all setup...
hey didn't i read somewhere you got "outclocked" on air by someone around here? :D do something about it hehe

Good to see ya Sky, Yea she kicked my butt with my own ram, sheeeesh! BTW everone ,SHE KILLED THE BOARD! Yep. She returned the board and got another and is at this very moment trying to duplicate that 227 fsb.
I went to radio shack to try and pick upa 20 and 50k pot for my mod but they didn't stock them. Will try again next weekend guess that gives me time to order a block from the danger den for my vid . Hey we got a new member .hopping to get some new chiller action on this thread .

Ok. I did it . Not a matter to be entered into lightly.I paid $450 for this card when it first came out.
here it is .

Now that I got it ready to generate some heat , I went to prepping it for the xtreme cold ,well not to xtreme just -25c

Here I pulled the heat spredder from the gpu the big @ss ramsinks are made from an old slot one heat sink that met my hacksaw.

Then I fliped the card over and covered most all the back with that dielectric grease stuff, added some weather stripping and pushed the mounting bolts through.Not seen in the pic but after I mount the block I will add two more strips to cover the ends of the bolts.

Now back to the front of the card where I added more grease and a layer of neoprene this layer sits flush with the gpu die to form a seal where the block will overhang.Note the dielectric grease in the center, up to but not on the die.

Ah! the resting spot for my block.I added another layer of neoprene to sit flush with the bottom of my homemade block mount.
Notice the offset bolt patern,the block I will be using is from my Corsair Hydrocool kit, a cpu block that I had to mount slightly off center to match the available holes in my vid card.

Ok Sky, do to lack of funds and just wanting to check it out and see how well it worked I'm using a microchannel design with the 3/8" OD 1/4 ID tubing nipples and tubing ready to go from the Hydrocool Kit. this tubing is good to -91f I looked it up.

To keep from having to break into my already insulated circuit and to keep from having to purchase a block with half inch nipples I decided to add a second loop for my vid, here is a pic with the hoses plumbed into my res and waiting to be insulated.

I managed ti fit a second pump into my res. this pump is only 1.5 inches wide and has a flow rate of around 250 liters an hour when the coolant is chilled down the flow rate is more like one liter an hour. the white tubing is ice maker tubing used for extensions as the hydrocool tubes were not long enough.

With a little coolant and some insulation I'm about ready to chill down for a loop test.

Ah frost! ok no leaks, bout ready to mount her. My mounting plate is visable here.

The rest I'll just let the pics do the talking.

:D

Yikes... Frost... LOL

;)

I'll have more info,temps and such after some test ,right now I gotta cLoCk !
see ya:banana:

i LOVE every bit of that! just that dielectric grease.. ahh.. that always looks so damn sick.. i mean.. i'll be doing it soon enough, but it still looks not right... i tried to keep all my stuff clean and gleaming and then.. well phase change has its downsides, i guess :D
ok now go clock! hehe
oh and something i'm not 100% sure on.. go search for the trick with the 59'series and their tempsensor. i don't know wether this was regarding the 59 or the 5950, but some of them shut down because they can't read negative figures and interpret them as high positives -> power down.

and what are the gpu and mem clocks default and those that you ran it with up to now - and naturally what's the new clocks!

good thing. so now i got to get working :D

I was also looking for it in he midst of my bookmarks file but couldn't find it....
If you get it please post it here, thx m8:)

jamaljaco-> fantastic job d00d, respect!
Pristine application of condensation proofing/insulation - eye candy man!
Oh, and your volt mods, almost wet myself from sheer beauty and cleanliness of your solder job!
Congratulations and keep us posted.

What about the rest of you guys, any progress?

Very nice jamaljaco :D

My card will look quite the same in a few weeks :D

i think mickey posted the part about the 59'series temp prob. as for progress.. i'm stuck atm. trying to get some stuff delivered to me.. can't do much of anything till those parts arrive :( and the itch is getting worse.. must .. not... use... vmod...... yet ;)

eh.. and you'll wet yourself again, when you see pics of my vmod. maybe not from its sheer beauty, but from laughing... ehhe

Bravo Jamal, Nice work indeed !!

Hope you get some good numbers from the additional mods. Anxious to see the stats.

PS Like the baffle mod on the condensor. Did that help the noise??

Also looks like the coolant is a little darker. Did you change the mix?

Here is the link to MM's 5900 vmod thread :http://www.xtremesystems.org/forums/...5&pagenumber=1
First off thanks folks for all the praise.
@ Sky, I Don't have the below zero thermal throttling issue,I believe thats for the 5900 ultra,mine is non ultra and stops at zero.
Ok now my lame attempt at some stats.First I'll try to describe the effects on my coolant with an ambient temp of lets say 24c.My chiller pulls my coolant down to -25c unloaded in about 20 minutes. It will drop another 5c over the next hour unloaded. Loaded ( 2600mhz)at idle with just the cpu and nb my coolant stays at -25c and bios reports a cpu temp of around 10c. With my video loop at default clock at idle the coolant hangs around -23c and my gpu hasn't gone over 0 no matter what speed.With everything clocked and volted as high as I can get it and a few 3D Mark runs the coolant reaches a sweltering -20c. Now thats some cooling power!
I must say I was impressed at how just a trickle of flow in my vid loop was so efective. I'm not kidding when I say I have maybe 5 gph flow . My ram sinks will ice up in a few minutes if I forget to turn on my computer while the pumps are running.

My default gpu is 400mhz and the vram is 850mhz.With regular water cooling and stock voltage I was able to clock up to 475mhz gpu and 950mhz vram simi stable . With modded voltage and my beloved chiller I can now get up to 600mhz gpu and 1100 mhz vram simi stable I can't resist the urge to tweek the volts higher as I can't seem to get my card warm hehe.My ram sinks seem very efective. They stay cold to the touch. My only concern is some of the other componets on the card that are working overtime. I have fans on them and will be making more sinks for them .

ehorn, good to see you keeping an eye on things;)
Yes the plexiglass shroud helps a bit with the fan noise as it keeps the air from blowing all over the place.It also looks pretty good and was a simple solution just two parts glued at a 90 degree angle. The other end is open.
And yes again on the coolant I switched from 70/20/10 methanol water prestone to 70/30 methanol prestone .I didn't like the water it was causing my hoses to turn a milky white color and didn't have the anti corrosion inhibitors I get with the extra prestone.Also I seem to get a couple degrees cooler with the prestone.

:( Your looks so clean and nice while mine looks like ass :p:

Kepp up the good work :D I'll post my setup this weekend when I get the infinity in and chilled :D I even ghetto clamp the GPU block on :O

Great! cant wait to see it,we need some more chiller action.

small update, just to state i'm still at it.. small steps at a time eheh.
i've vmodded my 9600tx... so far it works :) but it seems i can't get a measurement of the vdimm (doh, all other measurements work). oh and i did it MY way with hotglue! (yeah hotglue is the way, lol). i'll edit a pic or two into this once i get some. maybe tomorrow night.
i haven't floored it yet as it is still air-cooled (doh, i'm slow), but the dipswitches for enabling/disabling the mods do work as planned.. yea! if i get a reading on the vdimm tomorrow, i'll step it up a bit, to see if it can do 420/330 without artifacts. up to now 395/325 was the limit for 2k1, aquamark would start artifacting at 397/330..

/edit pic 1, vgpu
http://www.abi02.de/deepblue2k2/pixx/a_IMG_0928.jpg

pic 2, the new ati "control panel" :D plus some of the spots to measure the voltages.
http://www.abi02.de/deepblue2k2/pixx/a_IMG_0935.jpg

in case anybody wonders... that black think's a 8x dip switch to enable / disable individual mods (vddq, vmem, -, vgpu from right to left, as it's seen from the back). the 3 cermets upright should be quite obvious, again right to left vpgpu, vddq, vmem.
the 5-pin-block in the topleft corner of that add-on board can be hooked with plugs to measure the voltages. the 3-pin-block is for measuring the resistance of vmem- and vddg-cermets, the single pin can be used as ground and the two pins behind that are the points to measure the resistance on the vgpu cermets.
yeah.. i like it that way :D...
maybe i'll solder them some time soon.. i just wanted to get the feel without the ability to kill it on the spot :D

Sweet control panel. I wanted to make something like that but I got lazy. So did you just glue the wires into place no solder?

well everything on that "control panel" - have to like the name, lol - was soldered to the cables. after put under some hotglue to avoid shortening it inside the case by accident. all spots on the actual card are hotglued, no solder. but as said, i might solder them sometime but before that i will train soldering on an old bnc-network card :D.
and for the control panel - i just had to - control freak and all. i want to know what resistance i get once i crank the cermet. i thought of getting some old analog vu-meters, but lol.. that would really be overkill, tho nice for a casemod...

Isn't anyone ready to take the next step, and adjust the refrigerant charge?

If you have simply inserted the evaporator in a res, your system is not finished. It is overcharged for the load. This means that the temps are not as low as they could be, the oil is being diluted with refrigerant, the valves are in danger, and the compressor's days are numbered.

At the very least, you should install a piercing valve, and remove enough refrigerant to make the bottom of the compressor warm (60-70C/140-160F).

Gary's venting again!:D

Whoa Jamal you've inspired me to get working on my waterchiller and get it done :)

lol, i got some time to work on my chiller now, as my nf7-s got its bios scrambled... doh guess 229,x fsb was too much for it ;)

I'll be starting one soon, we just pulled 2 old aircons out of the office. I'm planning using them both to cool the coolant.

I knew nothing of this sort of thing, but this thread has given me somewhere to start.

The good thing is that both the coolers probably need recharging so i'm thinking of swapping to 408a and getting the aircon guy to install a valve like Gary suggested.

Anyway I'll have piccy's of the units up tomorrow night :D

Ooo sounds nice, i want to find an old aircon but havn't been able to find one. My next project i will make from scratch so should be a hard task but i love hard tasks.

2 ac's won't get you any colder than one,it don't work that way,it will however allow you to have a greater heatload but one is plenty powerfull enough. 2 is overkill on your overkill.
Also, why do you say they need recharging? Did the refrigerant leak out somehow? If it didn't leak out then your ok.It is a common error (my assumption) to think it needs a little freon or the refrigerant has worn out. Oh, and if you have yours professionaly filled the guy will fill it to match your heatload and then no need for the line tap vavle.:D
anyway I'm glad you found us welcome to the madness!:eek: It's good to have some new blood on this thread ,Gary has been riding my butt to get on with step 2. hehe
;) ;) ;) C-mon with the pics!

Hehe.

I was going to use two so I could increase the heatload. I'm hoping to run a couple of Prescott 2.8's @ around 4-4.1ghz and have them folding 24/7. I've been banned from supercooling in the house after my last project so it's no good for my main rig (but I;m thinking about a Vapo XE for that anyway ;) )

Of course she didn't say I couldn't move my computer into the shed :p:

Right on ,do you plan on having them as seperate chillers or is there a plan in place to share certain componets,pumps ,hoses ,res ect?,
this could rock!

Man, I would live in the shed if I were you , lol.
My lady is a geek and wants herself a chiller also. our projects take over the house, we share in the madness! it's quite nice really

heh yea if I did my chiller in my room I'd be pretty much screwed. thank god I moved it into the basement. I had 2 MAJOR spills so far :p:

LoL I don't want to push it, she puts up with me having racks in the study for my F@H farm and generally doesn't whinge when i spend $$ on my toys :)

I was going to run 2 pumps and 2 seperate loops with one res, which i was planning to custom make. I helped my dad build his boat so i have a fair amount of experience with fiberglass.

I was thinking of maybe a small 3rd pump aswell pumping from the pickup area to the return area to cool it quicker..


____________________________
|___________________________| <-- Return Area
|________Core 1______________|

|________Core 2 _____________|

I think i'll porbably fibreglass them into the res so the coolant must go through them :)

I just had a look at the aircons they are rated at 1.63kw/5600BTU with r22. So with 3.26kw of cooling, I shouldn't have any temp probs :banana:

Sweet, lets get some pics of those units and get started, hehe.

Don't know yet. I've been thinking about it and will probably only use one. Can you convert one of these to a prommie style system ?

They've both been operating in pretty salty conditions so atm they aren't in too great nick. This one is the worst.

Sorry about the crap quality of the pics, it's a new digicam and I haven't figured it out yet. I can't find mine :mad:, when I do i'll post up some high qual pics of the internals

Capalaba, what about you ?

Me St Lucia, bloody hot.

I just looked at the other one and the specs are different it's a 7000BTU unit. I'll probably use that one as it seems to work better.

@ Fats, where do you get all your air conditioning units?

hey , we starving for more pics over here ,lol. got any with the cases removed?

Well guys..i have read through this entire thread and think i have enough info to proceed.

I have a 10,500 BTU General Electric AC that i plan on using and I am currently fighting with it to get it apart. Seems as if new A/C'c are easier to get apart.


Anyway, my current big problem is I do not know enough about which part is which.....


Also all of the evaps and coils I have seen throughough this thread are just normal radiator looking ones, mine is covered in what seems like a MILLION tiny peices of metal all the way around it.

The other problem here...is which side is the evap...on the back side there is a U shaped thing covered in the tiny peices of metal that covers three sides around the back of the ac...the fan itself was "inside" this in the case....on the front of the A/C where the dials are is another one that i guess kinda looks like a radiator but still has the peices of metal ALL over it...I am assuming this is the evap that will need to be placed in the cooler?


Someone please help..i will take pics if neccesary

Take some if you can.

The best way of finding a evaporator would be looking for a termistor sensor, in the air path or directly connected to thge evaporator or...


... simply turn it on for a second ;]

Yea sounds like a big mutha. I have one like it that draws to many amps to run in my house. anyhow switch in on. The part that gets cold goes in the res. Pics always help.Don't sweat the wire brush looking fins,they are just a different style.

Yes i turned it on...ran for awhile...but i think somethign has happened to it...it ran fine last winter...kept an entire house AWESONEly cold...well it has been in a garage since and it has been very cold outside..i wonder if somethngs wrong...


I turn it on and I can hear the compressor and everything running..it seems to shake a bit..and then after about 5 mins it almost reminds me of it switching gears or something..lol....the sound gets gradually louder and then the A/C makes like a noise and the compressor shuts off? then the lines that were getting really cold suddenly get really hot...any ideas?

Ok ,I'm no expert, but i'll try.
Is the ac in its proper orientation, botom down,top up ect.?

well, at first when i was taking it apart it was upside down...but when I started running it, it was sitting the exact way it would sit if it were in the window

Only difference is...i took off the fan....does the fan HAVE to be on when the A/C is running....could it be getting hot?

I would let it sit for a few and try it again, sound like it tried to pump some liquid that didn't evap off. got pics?

It needs the fan on the condensor.

Ok...just so i can clear this up...the condenser is the part on back that is U shaped and the fan was "inside it" so to say......i take it the fan is used to cool it off?


Yes i am tryin to find a lamp around the house that i can put next to the A/C for lighting. I will get pics asap...


She is pretty dirty still at this point....OLD...lol

yes the condensor will be the part that was the back,the outside part, dont know about the shape of it ,they can come in many shapes,the fan here is used to cool and condense the vapor into a liquid. that liquid then is forced through the cap tube,a long verry thin tube that leads to the evaporator where the liquid boils off (part that gets cold) don't worry bout the dirt mine were in worse shape,lol.
the fan can be removed from the evaporator,pics will help a lot.

Ok..the U shaped part i speak of is the part that covers the top and two sides in this pic. The lines on the bottom get very cold right after the coil part..and they go to the radiator on the front...the fan i took of is connected to the motor in the middle there

Right here is what i suppose you guys call the coil. Sorry i am an extreme noob at all of this but desperately want to do this right and learn it completely.


The "coil" in this picture gets hot to the touch...and then were it straightens out it gets really cold...i don't know how refridgeration works but thats pretty cool hoever it works....anyway, these lines go through to the front which i will show next

Ok..the str8 lines go through the mtal plate and connect to the "evap?" in the front of the A/C

ok ,the firs pic looks like the condensor the back of the unit correct? the evap (the front coils) the part that will go into a res.

And heres the good stuff!


I think from looking at it this is 10,500BTU's...someone correct me if I am wrong. Also, if you guys who are way into this can tell if this is a good A/C to sue for this project it would be great!

the pic right above your post is the best i can get of the front evap...it is enclosed in a metal casing and i think it is welded together..i can't for the life of me figure out how to get to it...think im gonna have to cut it

Yea posted before I saw the pic.
you can remove any housing any way you need to but don't break any lines ok.

lol I think I have the same unit but i didn't use it it would trip my circuit breakers like 12 amps, put the fan back on the back, fire it up and see what it does

Yea it makes the lights flicker when it kicks off...im gonna eat some supper and then i will..thanks for the help..i will be back to this post in about an hour!

Yea ,in answer to your question "would this be good to use"?
yes if you can stand power bill run it for extended time w/o tripping a breaker and if you can get that evap into a cooler giving the length of the lines.
I personaly would use a smaller one.

Took the case off the compressor last night, the smaller one doesn't seem to be working all that well. It takes a long time to cool down the coils and the compressor is getting very hot.

The bigger one is still in a window waiting to get removed on wenesday, it works alot better. The fan motor has completely died in it and when I was running it yesterday it got the evap down to 0c very quickly with no cooling on the condensor, it overheated before it could really ice up but :D

Edit: I've got some more pics, I'll post them up when I get home from work :)

The power bill isn't even close to an issue...i have 5 computers running 24/7 3 of which are crunching SETI Wu's. Im pretty sure throwing a a/c in there for a bit ifn;t too bad. I already decided im gonna run a extension cord from the garage to my window for the power...that way it is on its own circuit


Same problem thow...put the fan back on and it still wants to kick off after a few minutes...

Gonna find a way to cut the metal off so i can get the evap free...and i am sure there is plenty enough hosing to get it to the cooler..

remove the thermostat thermocouple from the front of the evap and lets see how long it runs.
you should get beloved ice!

Is that the white wire in the pic of the front??


And she is running now..been running for 10 minutes...lol...i got mad and gave it a bit of a kick..been running since...

Yup, thats it .locate it to a warmer spot if you can , like on the condensor.

thats the spirit! lol.

lmao...i stuck it inside the heater on the wall right behind the A/C...thats what i figured i should do...set it to somewhere warm so it fools it into thinking it needs to be cooler!

No frost at all..it is cold to the touch but there is no frost...something must be wrong :(

Yup, we still got a fan blowing air through it. its most likely a squirl cage type,underneath that housing your were having trouble with. this is the fan that needs to be removed. remove the fan from the shaft and saw the shaft off,or just saw the shaft to remove the fan if you can get to it.the 2 fans will most likely share a single shaft, so disabling the fan motor wont help as you need the other fan running for the condensor, sorry I forgot to mention that important detail, lol.
these things wont frost up if they are still trying to cool the entire room.

The fans removed from the evap.

I can't find thermostat as such, just as piece of hollow hose that sits on the front on the evap, I routed that under the compressor. The first 4 'loops' of the evap get cold but it takes a very long time for the rest of it too come down.

It will completely freeze up the first 4 but the last couple stay at room temp.

well, my thermostat was broke or missing - or both ;) so i had to short it so to speak.. so now it will always run, which probably isn't necessary to cool my unit down good.

conflict, the last two pics you posted are your condenser, the coils are the evap and why the hell did they get hot?? (or did i get something wrong). btw if the whole rig has been upside down, you would flip it back to normal and have it rest for some hours - i was told 24hrs should be best - to let the oil settle at the bottom of the compressor. i know i always did this - maybe i'm being to "safety first" ;), but hell it won't do you no harm, just a test of patience, lol

Well...i finally figured out my game plan and I ended up taking a bunch of new pictures......not sure what the heck is going on though because i use a digital camcored to take pics and then a tv capture card to pull the pics and save them...my software for the card is refusing to work so im stuck explaining this all right now.


Anyway, i cut through the casing with a pair of bolt cutters and now have a safe route to sinply lift the condensor, evap and compressor all out of where the sit right now...once that is done i "should" be able to safely bend the evap to the opposite side of where it sits now so that i can put it in the cooler. It looks as if there is plenty enough line.
My only worrry is the fact that there are two hoses on the bottom and two on the top...gonna be a big trick to succesfully bend everything with no problems.

Anyway, she is now frosting up very nicely and the entire evap is layering up ith frost in literally seconds...looks as if a 10,500 BTU a/c is gonna do the trick !


i am done for the night....gonna play a game of NHL 2004 and then sleep...thanks for the help guys..more to come tommorrow!

Ok guys....i lost alot of sleep thinking of my plan for the night and the biggest problem I have right now is the fan. From my understanding it is NEEDED for the condesor.

Is it only needed to help cool it?

Se the big problem is the way this A/C is set up the lines go through the big bulky metal casing that everything is placed in. I succesfully cut through it and I can raise everything out of it and I plan on giving it a new home on a wood stand. But my problem is what to do about the fan. It is mounted nicely in the middle and provides perfect blowing to all parts of the condensor.

Would it still work well if I took a farely large house floor fan and had it blowing on it? that would work the best because it would allow me to work with the evap, compressor and condensor in ANYWAY i wanted. The way this is set up Im gonna have to completely switch the side the evap is on to have room to place the evap in a cooler.

Anyone know if my floor fan will work?

It is absolutely essential that the condenser has enough air flowing through it to get rid of the heat. Will the floor fan work? I have no idea. The temperature of the air leaving the condenser should be no more than 10C higher than the temperature of the air entering the condenser, if that helps. It would be best to work with the original design as much as possible.

The word "only" does not belong in this sentence. Insufficient airflow can destroy the compressor. It is important.

Well what doesn;t work about that is the fact that the original design of the casing leaves me absolutely NO room to move the evap more then an inch or two in ANY direction..in order to move the evap i am going to have to completely raise everything into the air out of the casing and then bend the piping to the complete opposite side.... i suppose there is still the chance of bending it to the other side and then placing the condensor and compressor back where they currently sit

OK..i figured it out and dang i wish my capture card was working..i have the evap in the cooler sitting perfectly....ALMOST kinked a line but stopped just in time..hopefully it isn;lt weakened under pressure.....im gonna take a cinder block and place it in the old casing and place the fan that was in the A/C on the side of the condesor so that it blows just the way it was before..... im thinking this will work

Bending tools make the job SO much easier. The tool firmly grips the entire circumference of the tube while bending it, making it virtually impossible to kink it.

Hi folks, just got in from work. Sound like things are going well.Conflict, if you havn't already I would grab a garden hose and wash all the bugs and such out of that evap clean it up real nice so your not running debris through your coolant system.

OMG guys i need advice...ok im using a 10,500 BTU A/C...im assuming that means it is capable of reaching VERY cold temps with this form of cooling...well..i am using a anti-freeze that is suppose to be good to -64F at 60/40....well....i mixed everything together for awhile in seperated container and then poured it in there.....literally within minutes of starting everything up i had a half an inch of ice on the first foot of line of the evap...and now it is rapidly spreading. I am thinking that a solid layer of ice can;t be very good because then it won;t have all the "area" to cool...by area I mean amount of piping open...i hope that makes sense...

Any ideas.....should my temps be this cold?

Yea one of the first things i did was clean out the evap...lmao...i put it in the shower in the basement (just a single stall shower that is hardly used during the winter) and connected a hose to the water lines from the washing machine....cleaned it out nice.


Well guys...im not sure what to do..i added a whole nother thing of anti-freeze...but to no avail...my evap is currently a solid chunk of ice


Any suggestions

Your running r-22 it will only get so cold, mine is -25c. the 10.500 btu's means it will handle one hell of a heat load. I have foud that the ratings on the antifreeze jugs don't apply here lol.

Are you circulating the anti-freeze? It needs to be kept moving through the evaporator coils.

yep shut it off and clean it out .lmao.
you need methanol straight or a mix of methanol/water or methanol/antifreeze. I prefer around 65/35 methanol/antifreeze.

ideas? dont use antifreeze, use something that wont freeze at the temperatures your chiller is runing at ;-) i believe gas line antifreeze?? or denatured alcohol is what you want. just make sure you seal theres up niceley otherwise it will evaporate and you dont want to breethe too much of it.
cheers, owen
