Shader clock increments

Just a reminder to those, who know this and a hint to those who don't.

Nvidia shader overclocking; It has been mentioned before, but I can repeat that "shader" speed is counted in 54 point steps. I.e.
[...]
1404
1458
1512
1566
1620
1674
1728
1782
1836
1890
1944
1998
2052
2106
[...]

Setting to 1800 = same effect as 1782, 1750 = 1728, 1850 = 1836, 1900 = 1890 etc.

I seen this about a year ago when I started pushing the limits on my GPU's!
Great piece of info, Thank You!

I think that post was mine too

I just thought I do a refresh for the newbies

I remember when I first saw this, my shaders on my GF were like 4Mhz away from the increment limit, so I just adjusted them 4Mhz up and my PPD rose nicely

What I found out though, that you shouldn't adjust the shaders separate from the core - they should stay connected with Fermi (and up). Basicaly the shaders are twice in numbers than the core (ex. my GTX 470 is @ 811core/1622Shaders). My previous card was a GTX275 and it was a different situation - the shaders could be detached from the core and adjusted considerably higher. With Fermi you don't get the performance increase if you do that.

Now thats a piece of info I didnt know!
I'm running a 560Ti SC and have my shaders maxed out but core is still stock!
I'm going to give this a try!

Thanx Again!
