8800gts with a memory clock of 1700Mhz (Effective)???

I'm kind of confused about the memory clocks of the 8800's, as well of a few other graphics cards. But, mainly the 8800gts since that is the one i currently own. On newegg.com the specifications of the 8800gts' clocks are 500/1600Mhz (Effective.) But running Rivatuner I find that the timings in fact are 513/792Mhz. So i was wondering if someone could explain to me the "Effective" clock rate. My only guess is that is much like the AMD processors, an example would be the AMD Sempron 3400+, while only running at 2.01Ghz it is rated at 3.4Ghz hence the name 3400+. Is that close?

P.S - I did search the forumz and did not find a post or thread, so sorry if i overlooked anyting.


~Shady~

DDR double digital rate take the rate X2 or 792 X2 = 1584 or close enuff to 1600. The 3400 is rated vs PIV Intel processors, meaning the IPC (instructions per clock) of the 3400 is equal to a pentium 4 at 3.4ghz or close enuff

what he said and what pavel corrected

your speeds are fine.
