GPU OverClocked?

[OceanWolf]

So it would seem that my GPU is over clocked and I don't even know how this happened.

I'm using a GeForce 8800GT and according to Nvidia the default speeds are-

Graphics Clock - 600 MHz
Shader Clock - 1500 MHz
Memory Clock - 900 MHz

And according to Rivatuner and other programs my speeds are-


Graphics Clock - 650MHz
Shader Clock - 950MHz
Memory Clock - 1620MHz

Now I'm not really into the whole overclocking thing so I don't overclock any of my hardware, although I do have some overclocking programs, they are only for my CPU, and I have never used them.

I do have RivaTuner but I downloaded that only to see if my GPU is overclocked.

The thing that baffles me the most is that fact that one of the programs lists my default speeds as the overclocked ones.

So I guess my question is, how did this happen?
Its really not that big of a deal considering that my temps stay at reasonable levels and the fact that its not overclocked that high... I just won't to know how this happened.

I have had some problems with this card in the past,(this is actually an RMA card, the first one I burnt out) and I haven't used the RMA card once(this would be the first time).

you can buy factory overclocked gfx cards and by the looks of it you have one
