new x1900 vid card and mod - 05/20/07 12:34 PM

Here is a pic of my x1900gt next to my old x1600xt.  Man its huge...a full 9".  I ordered up some forged copper Swiftech ram sinks and a mammoth Thermalright vga sink for it.  I thought I would post my OC' ventures for you all.  Its for my PC workstation, but the same principles all apply to the mac card.  Stuff should be here on Weds and Ill go from there.

By the way with stock cooling I have the gpu @ 625 (same as xt model) and memory@1440.

Okay, here is the heatsink removal and cooling upgrades.  I used a cooler from Thermalright, Swiftech copper forged ram sinks, Lian Li 120mm fan, Artic Silver5 and Arctic Silver Epoxy.  The ramsink came with aweful sticky tape which would not hold, so hence the epoxy.  I havent started the benching or overclocking just yet, but I can tell you that the Thermalright dropped idle temps around 10 C.  Not bad at all. 

Here are some more pics...

OC'ing complete, well at least with ATI catalyst control center.  I was able to bury all of the controls to the highest points.  >:D  Temps were unreal too, with it never going above 51C.  My x1950xt runs that same temp when at idle!  Foldalicous!

thats quite the tweaked/pimped out card.  impressive!

Re: new x1900 vid card and mod - 05/30/07 01:08 PM

Small update...card has been folding for 24 hours with a stable temp of 46 C.  Wow, didnt expect it to be that low.  I am trying out CoolerMasters new Viva Pro on a x1950xt and I will add that to this thread.  I do have to say this about the Viva though, because of its design, three of the ram chips get no cooling at all.  Hmmm, I can remedy that (stay tuned), but why should I have to?

x1950xt with CoolerMaster Viva pro.  No likey that I cant fit any heatsinks on 2 of the ram. Still runs cool as I continue testing.  Will update soon.

Stock x1950xt OC w/stock cooler folding gpu temp 69 C.  Not bad, but the Thermalright took close to 20 C off of the x1900gt OC!  Better get another one.  Room temp is 22 C.  Update soon.

very pimpin'

whats the current gpu/memory speeds?

I never tried a GPU cooler like that. The most I have done is used a old Socket 7 heatsink with a 80mm fan with adapter.

I will reply with my final stable scores shortly.  I BROKE one of the cards!!! :'(  While putting one in a case my wedding ring (figures) caught on one of the small square caps and it snapped off.  OMG!  Oh well, I will fix it and write a how too.  I tried with my soldering iron, but its far to cheap and the tip is too big.  Off to the hardware store to get some cool new toys.

New fix it thread a comin....

Re: new x1900 vid card and mod - 07/01/07 02:09 PM

I was thinking about the fix it thread and realized Anil8tor has written a great soldering guide....with that, Im skipping it.

The card is fixed!  Pretty tense I must say. wink

Because I am not that happy with the Coolermaster Viva and it wont even fit with my larger SB heatsink, I have ordered a Zalman 900 cu and some copper ramsinks.  I also ordered a 22" Samsung to complement my 19".  I will post some temps when it comes on Wednesday.


Right now I have the stock sink on it and had to modify the SB heatsink to fit, lol.

Re: new x1900 vid card and mod - 07/19/07 01:26 PM

Got my Zalman 900cu, ramsinks and lcd today.  Very dissappointed in the cooler.  Using ATIs ccc with the core at 688 I was running 101C.  Thats hotter than the stock sink.  Hmm, poor mounting contact?  Dunno, but I have done so many that I could do it blind folded.  I am going to watch the temps for a while and maybe try and reseat it.  I took a bunch of pics that I will post later after I get my tattoo!  LOL.

[censored] heatsink, useless in fact.  Checked and seated perfectly.  Added just a smidge more thermal paste (I try and have the thinnest layer possible).  Same results.  Damn.  Off to ebay it goes.  Here are some pics of the install though. >:D

More pics of the install.

Okay, so I ordered a replacement cooler, lol.  The Arctic Cooling S1 is on the way and will be cooled by a 120 or 2x80mm fans.  I will post the change with temps and OC clocks.

Really busy lately, but I got the cooler.  Zalman was passed down to my x1600xt.  WOWSER!  Its even bigger than my Thermalright (which by the way tops out at 64C with no fan, loaded!).  Anyway, here is a teaser pic of the heatsink...benchies to come.

Holy crap! Would you like some computer with that video card, sir?

Very nice.

Re: new x1900 vid card and mod - 07/28/07 06:22 AM

Yeah, the cooler is huge.  Running CCC temps maxed at 70C with a cheap Coolermaster 120mm fan.  I was able to max the clocks in CCC too at 690/950.  I am going to leave it at that though as folding does take a toll with cards being loaded 24/7.  I will have to say that the AC S1 cooler is killer!

Okay, I got another x1900 series card on eBay and it needed a cooler.  I removed the Coolermaster Viva Pro from an XT and put it on the new GT (the GT was only 75 bucks!).  That left the x1950xt naked.  Today I got in a CoolerMaster Aquagate Viva and installed it.  Pretty cool looking rig.  It is smaller than I expected too, so it could fit in a Mac.  I cannot test it yet, as its scratch built home is not quite done yet, but it will be in the next week...I think.  Here are some pics.  One of the assembled card, one of the polished copper block and one of the card installed w/o the extra fan.

Fully tested now and running at 690/1900.  These are at stock voltages.  The cooler isnt noisy either.  Its my power supply that kicks in when that card is sucking the juice!  Max temps during testing was 56 C.  Not bad.  I have to get some better ramsinks too.

Hmmm, wonder where all of the pics went for this thread? Anyway, I though I would update on the x1900gt one last time. I removed my h2o cooled x1950xt to sell and put one of my Thermalright/Swiftech cooled GTs in until my hd3850 crossfire set gets here. With passive cooling only, I was able to take the clocks up to x1900xtx/x1900xt speeds. Its running 648/1440, the max in CCC. Yeah, it will go farther with AtiTool, but there is no need to break it as it goes back to a folding machine in a week.
