Shader overclocking

Post by sbohdan »

as most of you know, OC'ing the shaders will give the most in performance boost when folding with GPU.
I'm not sure if it was mentioned here before but in case it wasn't: "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.

also, if not gaming, we can downclock the memory to both decrease power consumption and lower the cards temps (possibly gaining more headroom for the shader OC or just lowering uncomfortably high temps on the card overall)
I hope this was usefull info for some of you...

It would be really nice to see how many ppd increase it gives for each speed bump - say for 200mhz jump does it give you 5ppd, or 100ppd...etc guess it would be really hard to calculate though ;)

that would also be up to the gear you using ex: an 8600GT is very different from a GTX295 lol but actually it will give you way more than couple of PPD with any card. I guess its easy to see after you raise 1 or 2 speed bumps...
it's also nice to know this in case you can't raise the speed (mostly due to temps) but if your card is between 2 speed bumps right now, you can actually lower your shader speed to the lower limit and lower your temps, without loosing performance :ANAL:
