G80 Clock Frequency Table

[CaiNaM]

g80's gpu clock generator/crystal works in certain incremements. this was originally from something i posted in this thread, but i've had a couple pm's asking if i found the chart, so i figured it would be easier to find/search if it had it's own topic.

following is a chart which shows the "set" speed and the actual speed:

"set" frequency.....actual speeds
from-to................core....shader

509-524...............513.....1188
525-526...............513.....1242

i believe this was first posted on XS Forums, but i don't recall who should get credit for this info, but i'm sure many of you will find it handy.

Is there a G7x table, too?

I remember when AT was discussing these clock speed/fps plateaus.

Interesting, I never knew that - cheers for posting.

The table for G7x is different, but the idea is the same. Clock domains have been around for a while now, but not a lot of people recognize this.

I remember tons of threads from the G70 days where people couldnt figure out why their 3DMock scores werent increasing even though they were increasing the clock by 10mhz .
