GTX260 or GTX275

[eding1]

Hi. First of all, big thanks for this wonderfull app. Sorry for any language problems, because I'm from Spain.
I think that W1zzard can answer my question:

I recently bought a second hand GTX275 at eBay. The card hasn't any sticker or identifier on it. So I've used GPU-Z and it says is a PNY Geforce GTX275.
The card works well, but I've seen that the fan is always set to 60%. (With Nibitor: minDutyCicle=60%) while most GTX275 (Including the official PNY BIOS) sets the minDutycicle to 40%.

Could this be an overclocked GTX260 or GTX260+ with a GTX275 flashed bios? or it is impossible... The clock speeds are the same as the default GTX275, but I don't understand the 60% fan speed...

The GPU-Z tells me this:

The most important information (I think) is the 240 Shaders (only GTX275). Is this GPU-Z Shader count reliable? or it can be easily modificable with a GTX275 bios offering 240 shaders, but with a real 216 shaders hardware?

If it's a real GTX275, why the fan is set to 60%?

I can upload the bios if you want.

Thank you very much for your patience (too many questions).

i cant see the pic but i would belive what gpuz says, a bios cant make more cudacores appear from nothing.

maybe card is non ref and needs to spin faster?

I have an 8800gts512 that I used a bios edit/flash to set the default speed to 60% to reduce temperatures(stock was something around 30% at idle). I'm unsure if a gtx260 would crash if it was flashed to a gtx275 bios...(just a bet I'm guessing it would crash)

the shader count is reliable and there is no way to change it via bios flash on gt200

its simple whomever sold you the gpu used a bio editer to increase the fan speed thus meaning the card stays cooler. something many of us do if not by using software then by bios themselves i dont see what the problem is here as it just means ur card stays cooler which means it will have a longer life span as more heat means shorter life span

yea, i always use rivatuner and rock up the fanspeeds..

Fans are set to lower speeds from the manufacture to keep the cards quiet.

You can use a program (RivaTuner is one) to raise or lower the fan speed depending on the temperature of the video card.
