nekked 8500 (ihs removed)

[saaya]

my 8500 pro died some weeks ago and since i had some free time today i decided to "recycle" it

the ramsinks, the golden orb and the memory wich i plan to solder on my xabre200 to be exactly. moreover i was curious to see how the actual gpu of a 8500 looks like and id its possible to remove the ihs to get closer to the gpu and cool eventual hot-spots more efficiently.

thougt you guys might be interested to see how the ihs is set up above the gpu. the latest cards have cpu like packaging anyways (except for the fx cards)

PS: sorry for the bad quality

this is what the card originally looked like

[saaya]

she was a real beauty *sigh*

[saaya]

memory chips, some caps and heatsink removed...

[saaya]

after some sanding i could lift the ihs

[saaya]

under the ihs i found some more of the same ceramique, the same stuff memory chips and nb/sb chips are embedded into.

i guess the ihs is meant to work as some kind of shield to protect the gpu from emi? and maybe spread the heat to the whole gpu surface...

afer some more sanding i finally reached the actual core... shiny as a cpu core, squared and even bigger than a thunderbird core.

too bad you cant see it on those pics, you can actually see parts of the printed circuits on the gpu when you let it reflect light. looks really cool... i think i will use it as a key fob

Hmm it could be better quality ... It's very hard to see the 'fun stuff'.

[enzoR]

yea i agree... but i can figure it out a bit if you look at it and stufy it long enough.

In pic 5 your milk expires on jan 30th.....

[saaya]

my neighbour will be back from vacation in a few days and i will try to get his cam to take some high res pics of the core.

it looks really nice!

the actual core is at least 0.1mm under the ihs, this doesnt sound like a lot, but it actually took me quite some time to sand my way through the ceramique stuff after removing the ihs, even though i used some large grid sand paper. if anybody wants to give this a try i suggest to carefully sand through the ihs on one side and carefully get a knife or needle under the ihs plate from there and life the plate in the middle. then lap it some more to get it plane and you should have the best contact to the gpu possible.

At least something was in focus LOL..

I Think you must be right about the IHS saaya, must be there as a heat spreader.

[saaya]

see the toilet paper, snowy tree, nike sweater, remote control and the hand?

holst, i think i'll remove the ihs of my xabre as well, i will let you know if the card still works after the mod lol

looksmore like this btw:

[La1kr0diZ]

Oh mommy and wats inside?

Cool dude!

[Vlad Draculea]

that to me seems one of the treatements required for the people heads

[SupaMan]

heh, cool.

pics make my eyes bleed though, for serious good digicam is a great investment. PCB makes a cool wallpaper if can get a good shot

this one isnt the best, room's a bit dark...but you get the idea canon S45 (cropped a lot)

Dang.. I wonder how high a bare-core 8500 could OC?

*bump*

Holy crap dude, my camera can't even dream of doing that!

Every time I even try to get twice as far away as that, its so fuzzy you can't even make anything out, and its a 2.0MP Kodak, fairly new (02' Xmas).

[STEvil]

I should try my vivitar 3632 out for close shots.. its got 4x optical zoom.. and is 3mp through hardware interpolation.. paid $70 CDN for it.. heh.

[Soulburner]

Mine has 3x Optical and 2x Digital zoom but I don't use Zoom when I try pics like that....wouldn't it come out worse?

You should check if there is an optional macro lens kit for your camera. I have a Kodak DC4800 and the macro lens kit for it works nicely (example link).

Is there any possibilty a Nforce2 NB is also done like this? If so could it give better cooling and heat transfer? Anybody got a board to sacrifice?
