My "8800 GT"s....

[zombie67]

I have three 8800 GTs, or so I think they are, and I need help identifying them. Two are identical and double wide, one is a single wide card. The single wide card is a bit faster than the other two. Here are some clues:

From SETI Beta stderr:

Device 1: GeForce 8800 GT, 512 MiB, regsPerBlock 8192
computeCap 1.1, multiProcs 16
pciBusID = 5, pciSlotID = 0
clockRate = 1500 MHz
Device 2: GeForce 8800 GT, 512 MiB, regsPerBlock 8192
computeCap 1.1, multiProcs 14
pciBusID = 3, pciSlotID = 0
clockRate = 1500 MHz
Device 3: GeForce 8800 GT, 512 MiB, regsPerBlock 8192
computeCap 1.1, multiProcs 14
pciBusID = 4, pciSlotID = 0
clockRate = 1500 MHz

...and from the BOINC event log at start up:

CUDA: NVIDIA GPU 0: GeForce 8800 GT (driver version 320.18, CUDA version 5.50, compute capability 1.1, 512MB, 456MB available, 576 GFLOPS peak)
CUDA: NVIDIA GPU 1: GeForce 8800 GT (driver version 320.18, CUDA version 5.50, compute capability 1.1, 512MB, 448MB available, 504 GFLOPS peak)

Hey Z,

For me at least, the info you posted is too generic to ID the manufacture/model. On the pair of 88s I used to have, they each had a reference number printed on the trace side (Back) of the circuit board. That # can be Goggled to find the make/model. But not all brands did that back then and fewer do it today.

Yeah, I was hopping the difference in "multiProcs" would be meaningful. But I can't find anything with the GT 8xxx series that changes from 14 to 16.

Ah! I forgot about GPU-Z. I've been using afterburner too long...

Anyway, according to GPU-Z, the two have 112 shaders, and the one has 128. According to wikipedia (http://en.wikipedia.org/wiki/8800_GT), the two with 112 are 8800 GT. So now we know where the SETI nomenclature comes from. 112/8=14 and 128/8=16. So SETI divides by 8 for some reason.

128 Shaders is either a 8800 GTS, GTX, or Ultra. Memory is 512, so wikipedia says it must be a GTS, as the other two are 768. But then it gets weird. Clock rates are 650/575/612 respectively. But this card is 602. And the memory clock is 900, which says it should be a GTX. And the shader clock is 1512, which says it should be the Ultra.

I think I will have to shut it down, and pull it out to get some SNs or something.

Says it should be a plain old 8800 GT. Yet it clearly has more shaders. Bizarre!

Sweet, I think you may have gotten a card where they needed to fill a quota with whatever stock they had, and so they used a slightly higher-end part on at least one of the pieces. Reminds me of AMD binning a quad core down to a dual or triple core part, just to fill their orders for those SKUs. :)
