Radeon HD7770 and 7790 doing N-Scrypt. HELP

[Speedy]

I have serious problems mining with these cards.

On Scrypt, i can get 160khash on 7770, 200khash on 7790.

On N-Scrypt. Nuffin' works.

ASUS HD7770-DC-1GD5-V2
Using

@echo off
color 0A
setx GPU_MAX_ALLOC_PERCENT 200 (changing this to 100 doesn't change much)
setx GPU_USE_SYNC_OBJECTS 1
vertminer.exe -o stratum+tcp://pool:port -u worker -p pass -I 15 -g 1 -w 256 --thread-concurrency 7300

I get 3-4khash.

On XFX R7790

setx GPU_MAX_ALLOC_PERCENT 200 (Changing this to 100 doesn't change much)
setx GPU_USE_SYNC_OBJECTS 1
vertminer.exe -o stratum+tcp://pool:port -u worker -p pass -I 18 -g 1 -w 256 --thread-concurrency 6500

I get 10-12khash

What am i doing wrong/missing ? Anything else needs to be loaded ?

I get 3-4khash.

For HD7770, try this: -I 12 -g 1 -w 256 --thread-concurrency 8000

It works for me, and get about 75KH/s.

I can't even get 4khash with that setting
