256-bit 8600gts

[captinhector]

I just realised I have a 256 bit bussed 256mb 8600 gts. I haven't thought about overclocking my 8600 because its so fast vs. my (oc'd)7600, but just installed RivaTuner and it says it has a 256 bit mem bus.

(I have performance profiles set, clock speeds are much slower)

GPU-Z shows completely different specs(including 64 shaders)....

The 256bit bus does make more sense though. I can turn up to 16x aa,16x aniso@1280x1024 and the fps in non gpu limited games (dx 9 games) doesn't really change. Anyone heard anything else about this?

Nice card.....Got a bench mark so we can see what she does?

I have all the settings in riva tuner set to quality, and this is what I ended up with.

Everything is with default settings in the programs

... I just realised that that I've had it on slow performance profile....
above is 500/1100 now @ stock speed 625/1450

This thing is cpu limited, but I will have my opty 175 in/on/around dec 20. or so.

Not bad with that CPU and quality settings. It seems to give the 79xx high end cards a good run...

[captinhector]

Yes, but 8600gts's are supposed to have a 128 bit bus ( GeForce 8600 ). I just was wondering if the rumor mill, which had talk of the movement to 256 bit bus's in Dec. came true? I mean, is there a specific way to tell?

Interesting. Do you know if there is some way to change older 8600GTS cards to 256-bit bus?
