Which GTX260 Did I Get?

I ordered this EVGA GTX260 from newegg about 2 months ago, and it has worked great. I wanted to overclock it a little so I could turn on AA without a big performance hit, so I installed EVGA Precision.

What is a little strange is that the clock speeds precision is reading is different from the specs on newegg. I thought this was just a software problem, so I installed RivaTuner, but that was showing the same speeds. The 1260 version that I ordered has 576mhz core and 2000mhz memory, but Precision and RivaTuner are showing 626 core and 1053 memory.

If I'm correct I think these are the core 216 superclocked edition speeds. How can I tell what video card I actually have? Does it show somewhere on the actual card?
 
download and run gpu-z, it will tell you the number of streaming processors for your card.

you might be one of the lucky ones that ordered a 192 and got a 216....
 
I didn't see anything that said streaming processor, but it did say there were 216 unified shaders. I didn't see the number 192 anywhere. Does that mean in November I got a 216 core for $219!?
 
Is there any way I can figure out which EVGA model it is? the 896-P3-1260-AR is what I payed for, but I don't think it's what I got.

Here is what GPU-Z shows:

I just bought the eVGA GTX 260 SSC 192 version and it shows 216 unified Shaders in GPU-Z as well.

Someone mentioned that GPU-z might be reading the driver for some items and not directly from the card.

I would have to think its a driver thing..what are the chances of either A.) Nvidia not knowing which cards they are labeling, or B.) So many people are just that lucky, myself included.
 
So, does that mean that the driver is automatically overclocking our cards?

Well, at least mine, seeing that stock on my version is supposed 576mhz?
 
I recently ordered a GTX260 Maxcore 55nm card. It was the standard 576mhz edition but my GPU z is also showing it as the 626mhz Superclocked edition. The box even says it's just the basic version. I guess I shouldn't complain but GPU-Z could be showing me the wrong data.
 
If you google for "gpu-z 216 192" (without the quotes), you'll find a lot of postings on forums about people who bought 192s that report as 216s.

In the threads I read, there was never a clear proof about whether they really are 216s, but the consensus seems to be that manufacturers may have quietly substituted 216s for 192s when they ran out of 192s, because the alternative explanations seem much less likely.

The same thing seems to happen with some customers getting overclocked versions instead of vanilla versions - it may be that when the manufacturer runs out of the vanilla cards at high-demand times, they'll quietly substitute overclocked cards instead.

Factory overclocked cards have their default clock speeds modified in the card's BIOS, so Precision and Rivatuner aren't lying about the clock speeds of the card.

GPU-Z is known to often not be able to tell the difference between 55nm and 65nm, but it isn't GPU-Z's fault. 55nm chips often report themselves as 65nm because the chip maker didn't do anything but shrink the size of the chip and left everything else exactly the same - including the part that reports what chip it is. This is known to be true with the 9800GTX to 9800GTX+ upgrade - all 9800GTX+ cards are 55nm, but may report themselves as 65nm. This may have happened with the GTX 260 65nm to 55nm die shrink as well.
 
Anyone with the GTX 260 original with 192 shaders want to post their GPU-Z?
