8800 GTS Question under GPU-Z

[BuildNoob]

I know, I know, this is a 5 year old GPU, but this is making me fully curious.
I have gotten a EVGA 8800 GTS a year back, not really messing with overclocking or checking specs, it as i had it under linux. I just recently installed it, overclocked it, and it has a cluster of stream processors enabled?

Does the card performs worse now?

Not as far as i can tell, i have rivatuner, so i'm going to see if i can deactivate the cluster, and get a score for the disabled cluster in something like furmark

Finished benching on Furmark 1.15.1.0 on 1280x720 benchmark, top is with streams disabled, bottom is streams enabledhttp://imgur.com/a/Mb1WB. Maybe i got lucky with a batch of streams not laser-locked properly?

There are actually three versions of the 8800 GTS released by Nvidia. The first version released in November 06 had 96 stream processors. In the following year, a 112 stream processor version was released with the same name (the card you have). Lastly, they released a version with 128 SPs on the new 65 nm fab, called the 8800 GTS 512.

Ah, ok, i was wondering why that was there. well, i'm just going to bag this GPU up since i got around to flashing the bios. Thanks.

I actually have a question for you if you don't mind. I have an 8800 GT that I've been playing with and something about it has made me curious. The GPU clock, memory, and shader clock all stay at their max speeds, even at idle. It doesn't matter what the load is, they don't change like on newer cards. Was it the case with you too? I know that Nvidia may not have released a 'Speed Step' or technology to change the frequency based on load yet, but I thought they would have had it by then.

yup, its just like that, just locks at its set frequency. Im sure that something like the GPU BOOST didnt come along until like fermi or kepler, which didnt come along until years later.
