Nvidia 8800GTX overclocking: does the card OC like you think it does?

@ 2007/02/26

At Thetechrepository forums, Tony has a look at the real clocks of the nVidia 8800GTX cards :

"Like everyone else I thought you could clock NVidia cards 1Mhz at time, thing is it actually looks like it does not work like that at all...

Some cards have a higher default shader clock, like XFX:

580 - 576 - 1512 - default
585 - 594 - 1512
596 - 594 - 1566
604 - 612 - 1566
616 - 612 - 1620
617 - 621 - 1620
635 - 348 - 1620
637 - 648 - 1674
658 - 648 - 1728
662 - 675 - 1728
679 - 675 - 1782
680 - 684 - 1782
693 - 702 - 1782
700 - 702 - 1836
712 - 720 - 1836
721 - 720 - 1890
725 - 729 - 1890
741 - 729 - 1944
ATITOOL clock - real clock - shader clock

we saw the same with 7900 series btw.

Jup, the (only) thing that Tony adds are the real clock speeds that explain the real world differences (like on Anandtech).

In my opinion though, reviews (like Anandtech) should not display mhz for core and memory as they do now, because they don't mean anything... they should recalculate to real clock speeds.
