GUIminer asus HD5770 CUcore is putting out less than supposed?

[godofal]

im running my HD5770 on 925MHz, but only getting 160Mhash/s max (no other use)
on windows 7 ultimate, GUIminer using the openCL

if i read other people's post, i see that theyr getting 200+ Mhash with the same or less clock

what am i doing wrong?

What version of CCC? What flags are you using?

[godofal]

im using CCC 11.5 and im updating to 11.6 right now edit: updated, no noticable improvement
and what are those flags and where can i find/change them?

[fitty]

In guiminer there's an "extra flags" field next to the device drop down menu.

Try adding "-v -w128" without the quotes.

Also try "-v -w256" and "-v -w64" to see what works best.

It looks like "-v -w256" should work the best.

thanks! tried them, and with 128, i get 194.7 as my highest result
what does this do exactly?

edit: found another setting: -v -w128 -f0 gives me 198 max
keeps getting better and better
two days ago i thought all i would get was 140Mhash/s  

edit2:
*dances* using the phoenix miner now, and i broke the 200Mhash/s barrier, doing 208.2Mhash/s now wich is pretty damn good imo
using: VECTORS BFI_INT FASTLOOP=false AGGRESSION=12 -k phatk WORKSIZE=128

thanks for pushing me in this direction, 40~50Mhash/s for free thanks to you

I get just over that on my 5770 at 950MHz/333MHz on Phoenix with very similar options.
