Dude, why you be trippin? It's not like you're gonna leave it on stock speeds anyways, are ya?
What is the evga MODEL NUMBER printed on the tag on the back of the card? That would be a good place to start if you're that worried about it.
The only truly accurate way to determine (that I know of) your actual clock speeds is via the RivaTuner graphing functionality. And even so, it may not match what the mfg claims the clock rate is because usually they report whatever ntune (or gpuz, or rt) will show your sliders as being at (i.e. what the driver has listed as the clock speeds). Unfortunately, the *card* has a mind of it's own, and only uses what it's told by the driver to *estimate* where the clocks should be. The real clock is then calculated by the card, based on the clock 'steps' it has available.
In other words, you *should* be seeing whatever the mfg claims the clocks are by looking at your sliders. But that is not always accurate, you have to look at the graphs. If neither of those sources matches the mfg claim, then that is somewhat odd, but not unheard of at all. And nothing to worry too much about.
