TPU has some high res shots of the 9800GX2 up thought i would post them here to see what all of you could come up with :D

and heres how to take apart the card

It it official which water works will work?
Koolance already has a garbage aluminum block made. Dangerden and EK i believe are in the process of designing FC blocks as well.Quote:

Innovatek ( sigh ) has their... beep... released as well.
i wonder if you could mount 2* HR-03-Plus's over the back of each pcb?

Anybody know if these all use Samsung memory?
My vGPU/MEM mods.
Spot the wire that fell off :P

Hi T_M and guys , how well does your gx2 clock without mods and with mods ? Im going to get a single gx2 for my maximus Formula and will have it water cooled when the blocks become available .
:up:
T M did you try this mod on air?probly not but was wondering if ok to use with just stock air cooler?i dont want the card to breath to much heat.
anyone with the mod on stock air? results?
@aussie 760 ish 1900 ish and 1140 ish is the avg i'v seen around
mine does 790/1960/1140 for benches
Cool , so these cards are more like a pair of 8800GTS 512 than 9800gtx right (in clocks and performance) ?
cowie - what does yours bench like ?
:up:
it benches just like my pair of 512 gts
i geuss i'll do the mod on stock cooling and report back
So this is SLI for non-SLI motherboards , right ? Nvidias way of getting into the Intel powered motherboard sector ? Perfect partner for my Maximus Formula .
:up:
Sorry for jumping in but I had tried it with stock air and cold air at that. I only tried up to 1.15 from the stock 1.375 and saw no improvement over stock. Cooling is what really helps these cards.Quote:

Is that why Kingpins card clocks so high without mods ?
Is that meant to be the other way around ?Quote:

thats what i was thinking,because the colder i get it the more higher and stable clocks i can bench at.....was it good for at least 850 and 2200 or higher shaders?

well i've got some data to share with u guys :) this is for 3dmark06 aye.
-40 degrees cel ln2 tek9 4.0
w.o mods: 800/2250/1150
w. mods: 920/linked (haven rammed it since i ran out of ln2)/1200
1.35Vgpu and 2.35Vmem
@harleybro dosent ur card get the cold throttle issue with dice? since its probably at -60 to -70?
PS. a tip for the guys modding this card. use a sharp screwdriver or something to scrape a little off the pad u wanna solder. there's something like a protective laquer that prevents solder from biting easily. this is for my card at least :)
Thanks Raven , I want to get one of these and will vmod it on water with maybe a little bit of dice chilling happening too . Im watching everyones results keenly.
:up:
here are some other mods for the cards, but on the same circuit with measurements on the backside. These are Vince´s shots, but i am sure he dont mind sharing this :)

Nightraven: I cheat out the cold bug by using only dice. No acetone is added. If I use acetone then I do get the cold bug. ;)
On a side note can anyone figure out the OVP mod on these?
oh man thanks bro for this!Quote:

no wonder!!!! haha i see good idea also huh!Quote:

You got a 1.5 card? Is it leadtek? I know most are able to use only 1.35 including myself. :confused: :(Quote:

nah nah i was benching 1.35V too. read above posts :)Quote:

however, above 1.35V, it would blank out mostly at GT2 for 06. so i figured it was OCP :)
Its single card that have internal sli, so yes it will work fine on any motherboard that have PCI-Express 16x or better.Quote:

Next ill add some inductors because the vcore OCP is still a problem.
thanks for posting that T_M. off to get some VRs today. Waterblock I''ve been told is being sent out today as well.
I'm guessing on future cards we will finally get control over the voltages without mods.(Not as much fun I know).

Thanks to you guys for posting your pics, really helpful.
Mods gone ahead just fine. Followed a bit of Vince's and a bit of T_M's. Didn't even need to take the card apart.
Just waiting for the waterblock now. Hopefully today.....
Cheers:up:

Hey guys, a little help please.
First off, I'm very new to doing mods myself. I've only pick up an iron a few times. But I'm trying :)
I'm doing the vgpu mods for the GX2 and I just can't get one side to work, and am looking for ideas to try.
This side works just fine and was easy to do:
http://img528.imageshack.us/img528/8183/img0518lf7.jpg
But this side does not want to play nice at all. I also tried the vcore point in red in post 20 of this thread with no luck.
I'm open to any ideas that may help.

Hey deanzo, I dont see a vcore mod done on the bad side? :confused:
Am I blind? Looks like you did the mem mod on one side and the vcore mod on the other...
I marked in green where the other vcore mod should be that I am not seeing. I use resistors tied in with same ciruit as the solder pads that everyone uses.
Yep spot on Vince, thats not the vcore mod you've done Deanzo, you have actually connected the vMEM read point to ground via the VR :shrug:

When I was looking at T_M's picture, I thought the vr are went to the point I've just marked green. But in fact it needs to go to one of the two points I've marked in red.
Hehe, you could say I got my wires crossed looking at the picture :D
hehe, at least its resolved easily
After somehow killing the vr :shrug:
I've changed that and soldered the wire to the point Vince pointed out, and it all works now :).

Thanks again Vince & T_M :up:
Hopefully this will help with OCP limits on LN2:

http://img.photobucket.com/albums/v310/T_M/IMG_3830.jpg
Nope... didnt help at all
What disconnect OCP? The Card can work under 1.355, but anymore put. 1.375 brings about Black screen.....
With has done so
http://ipicture.ru/uploads/080624/thumbs/QPFZvBAojT.jpg
All work, but more 1.355 not to expose. That else possible to do? :D

Cold water, pci-e@125, vGPU 1.360, Caps mod :up:
Bit early to tell, but I think the IC resistor on my top card (The one Vince used) is failing. My voltages have been fluctuating quite a bit.
Set initially around 1.2v, throughout the day I'd notice my voltage increasing , sometimes to the point that the OVP would kick in.
if I run vantage this would happen almost immediately 1.2v straight up to 1.34v. Sometimes the reverse would happen and the voltage would drop down to 1.1v.
I've re done the solder a few times now, and I'm now on my 3rd Variable resistor, but my conclusion is that the VR's are fine. So after no joy, I've tried taking the voltmod off, and fortunately no fluctuation.
Anyway I've now moved my solder point from the IC resistor to TM's point and fingers crossed this seems to be working just fine. Steady at 1.21v.
As I say I can only presume that the IC resistor is failing, but I really don't know. Anyone here, have any similar experiences or have any info on this?
Cheers
RLM
