8800GT in my rig

7900GS vs 8800GT



the GPU is sooo big compared to 7900GS, so i need a vmod anyone has done it?

metro.cl,
vGPU and vMEM mods should be quite similar to those on 8800GTS/GTX, macro shots of the areas highlighted in the jpg attached to this post would help to pinpoint the exact soldering locations.

The rectangular chip should be labeled:
Primarion
PX3540BDSG

DO NOT USE THIS IMAGE

will update proper one soon

Thanks, dinos22.
Need clarification on the existence of certain traces and few resistance measurements, see attachements.

First pic:
There should be traces between points 1, 2 and 3. It certainly does look like there is a trace between 2 and 3, but is there one between 1 and 2? = if there are traces between 1, 2 and 3 then resistance between each is ~4-6Ω.
Also,
Resistance between points 2 and 4? (might be <10Ω)

Second pic:
Resistance between points 5 and 6? (might be around 500Ω)

"the GPU is sooo big compared to 7900GS"

the ihs u mean is bigger?the 7900gs is naked and has the bigger die.


"Thanks to a die shrink to 90nm, the G71 GPU on the 7900 GT was able to deliver the same basic technology and performance as the 7800 GTX while running cooler and costing less to produce."

"Well, the 8800GT is 65nm instead of 90nm. Smaller die size might have dropped the cost quite a bit. And who knows what ATI has coming. ..."

so its a bigger ihs with a SMALLER die 90nm(g71-g80) shrunk down to 65nm(g92)..i honestly belive naked gpus run way cooler.wish my gtx was naked.


sorry fugger,was telling him die shrunk..

Both are naked.

You know you could always take off the heatsink and see what happens.
Honestly i don't see how a naked GPU would be cooler than one with a good heatsink and thermal compound.

Just like a naked CPU runs hotter than one with a heatsink and good thermal compound. Metal just conducts heat better than air thus you can move heat way from the source faster.

Now back to the topic, I can't wait to get my hands on one of these. I plan on seeing how far i can push it before it breaks. Can anyone tell me how hot does this card usually get at stock?
