GPU SS unit testing

[Linuxfan]

Hey guys,
I got a used modded SS unit from XS in this morning and am going to test it out soon. I have no idea how it will handle my 5870 or other single GPU cards, so I'll just have to test it and see! :thumbsup:
So far its a quiet little unit, nothing compared to my 2 stager cascade, and shows about -50c on the temp probe.
Here are a few pictures.
Hopefully I'll get a chance to stick it on the 5870 tonight, we'll see though... right now I'm finishing a case mod to get a 5970 to fit. :)

sick .... who built it for you ???

[Linuxfan]

I heard a few years ago kingpin owned it... It has been upgraded and unused for a while... Got it from cowpuppy. :)

[Buckeye]

Interesting to see how this performs.

I have a Chilly1 here that I havent used in ages and ave thought about doing this. Only problem is has the standard evap enclosure and I havent spent to the time to mod it to fit a GPU.

I expect it should work fine tho.

I have a round of new tests coming up soon that I will use it with, not related to GPU's tho., then I don't know what I will end up doing with it.

looks swank :)

The 5870 should be a good test card, some of them get pretty damned hot under load. Unit looks good, may the clocks be with you. in for the results :)

[Dentlord]

Looks good, man it would be nice to have gpu on SS and not have to constantly scoop dice into the hot bastards lol

[Linuxfan]

Didn't get to make the mount for it tonight but it'll be done tomorrow!
Looks like the 5870's gpu core size is much smaller than the GTX 280 I have here... It'll definitely fit the evap's head better than the 280...
Would it be bad to use it on a bigger core with such a small tip? I wouldn't think it would take the heat off of the whole chip as well...

I got it for pretty much the same reason as my cascade unit... Ease of use when benching for long periods of time and the lack of the constant supply replenishment that you have with ln2 and dice. ;)
I can take my time and tweak my clocks and odes for hours without really wasting anything...
Also this seems to be the better option for me because I'm still 15 and don't have a drivers liscense to run out and get ln2 or dice every few days... :rofl

Shooting for 1100+ core on the 5870 if this performs ok. The card does 1066/1330 through all of the 3d marks on the stock cooler at 1.35vcore...
I'll be sure to get the temps of the card in while idle@stock and then monitor the max while@load overclocked and bolted in one of the 3dmarks(probably a vantage gpu run).

I hope this testing will make it clear whether it's worth it (how much difference it makes)to add a rad and a gpu waterblock to your loop or to get an low end ~$300 SS unit that holds decent temps.
Thanks for all the interest! :)

[Splave]

I think you will hit 1150 if it can hold the load.

Can always pop the lid off the 280, the chip is big but way smaller than the ihs

[punx223]

be careful if you decide to pop the top on the gtx200 series cards as you can chip the core quite easily

I don't think you'll have any problems with the smaller evap head on the bigger ihs. If you look at the ln2 gpu pots in some cases its the same disparity but still the ihs gets plenty cold lubbin.

Cascade and phase on the gpu= no excuses! :keeporder:

So no pressure but dammit man, we'd better see some ownage clock for clock ;) :laughing:

Yo bro seen plenty of mods out there as long as you only have one card a standard straight evap. will work fine with som field alterations for the bolt paterns..... LOL

[Neuromancer]

Interested to see how this holds up. Would think older SS might be okay for some older cards, not sure of the top of my head where 5870 fall in TDP land, hte 5970 was tapped at up to 300W though yes? So I imagine a solid 200W load is doable on the 5870. Yikes!

[Splave]

also I know the same as a cascade, you have very little mass transfering the cold on the evap compared to a giant block of some sort with dice/ln2

[Linuxfan]

Got it mounted and booted it up... Gpuz and afterburner showed temps in the -40s. Saw it go down to -49*C.
I thinking need to insulate the card from the condensation or I might have problems... It'll drip otherwise when loaded.
What should I do to protect the card? Use eraser like on my motherboard?

[ReverendMaynard]

erasure for sure. Looks like a decent unit LF.

[Neuromancer]

Also need to protect the motherboard by the card as well. Gravity is a bitch

[Linuxfan]

Got it insulated, movbo top... Here goes!
Thinking about making an upside down rack... :confused:

[Witchdoctor]

I was dicing a card a few weeks ago

eraser the front and we used sill sealer on the back and tapped it on.

put a slice as long as the PCIE in a sham wow and stick the card trough it
it shold be tight to the interface

Not a drop


Teh Sex

[Linuxfan]

Lol I put too much eraser on the card myount isn't tight enough and is running -1c idle......... Time to redo ;)

[Witchdoctor]

Man when we did it it was real thin. lower than the memory

really knead it till it is soft work it in your hands and don't forget to be packing a hair dryer in your tool box ..... it is your friend

[Splave]

hate when that happens

[ocgmj]

Put the eraser in the microwave for 10 secs to soften it up.

[Kal-EL]

Happend to me once, quick adjustements on the fly. I usually do a dummy mount, then pull it off and check the TIM spread. Get er re-dun and flyin bro. ;)

[Linuxfan]

Update....
Seems like this unit doesn't hold an overclocked and overvolted 5870's load too well... :ohcrap:
The screenshot of the afterburner reporting -48C was the first boot up without eraser... It now runs idle at -28 to -30C. I haven't seen it go down to the -40C area at all after I installed the eraser. What would be making it run hotter@idle now? Maybe it just can't handle the load and is contacting the die perfectly....
I'm using AS5 on the GPU...
I doubt the eraser around the whole GPU die would kill the temps...
As you can see in the first screenshot, fully loaded it is hitting in the +30C range. At stock it peaked in the +20s. :eek:

[Splave]

damn, I think its because AB ramps the clocks up even at idle which really heats things up. And yeah I think the temps were lower on the SS before because it wasnt making as good of contact.

[ReverendMaynard]

I agree with splave, better contact, hotter temps but the AS5 isn't helping.

[Linuxfan]

I'll remount this evening and try again to get temps down...
Just want to get it to stay under +10C on load.... :blink:
Should I try Arctic Ceramic or MX3?

[Splave]

Ac imo

[ReverendMaynard]

+1 with ac

[Witchdoctor]

Sub zero I don't think it wioll matter what paste you use I use What ever I have on hand for mine .... have not really noticed any difference personally.

It may be a tuning issue. As if it was dialed oin for older cards it certaily won't be ideal for these new beasts.

I would throw it on an older card to see what happens ......

May just need a metering or refrigerant optimization

[Linuxfan]

Was thinking same thing WD...
I don't have a smaller or older card to put it on ATM. :rofl
I'll do that soon as I can though. :) Vista has a 5770 to test...

[Witchdoctor]

You have an 8800 on the way right, that would be a good canidate

[Linuxfan]

Yeah.... I guess the 88GTS 640mb wouldn't run as hot as the 5870?

[Splave]

def not, the 8800gtx on the otherhand is a pretty hot card.

[Linuxfan]

Got an 8800 GTS 320mb in... Debating whether I want to have a go with this unit again or not..... I'll probably go for it after running it on cold air...
Thinking I should sell it to someone who isn't planning on loading it so much and trying something else soon...
