And topic is dead…

aah…

I said only thing you need is to add --xintensity 3, increase worksize to 256 and you are done, leave other settings alone. And those are not settings for 400Kh/s, those are for 330Kh/s and you can safely lower your freq to reduce power consumption and not lose performance.

With which driver version?

Rewrite pretty much all of the kernel

o_O

Wolf0, you said this:

Oddly, even on my own in-dev kernel, my 290X at 1125/1600 (memory type unknown) does 250kh/s, while my Hynix 280X does 255kh/s - 265kh/s at 1150/1500… weird.

And how this get on win7 with SG5?

255 kh/s )) I wanna it )

Wolf0, and how to get 270 kh/s on 280x as you (with SG v5 on win 7/8)?

Omg… Don’t understand why it is needed.
