I can't get these 7xxx cards running any good on n-scrypt

Asus asus-hd7770-dc-1gd5 (The machine has 8GB Ram)
@echo off
color 0A
REM setx GPU_MAX_ALLOC_PERCENT 200
REM setx GPU_USE_SYNC_OBJECTS 1
vertminer.exe -o stratum+tcp://pool:port -u worker -p pass -I 12 -g 1 -w 256 --thread-concurrency 7300

I get 160khash on cgminer. I get 3-4khash on N-Scrypt

XFX R7790 (The machine has 32GB Ram)

setx GPU_MAX_ALLOC_PERCENT 200
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 200khash on scrypt. I get about 10-12khash on N-Scrypt

Can anyone help me tune up these cards, for scrypt mining.

I seems like the whole thread is 270-280 and 290 cards. PLEASE We need some settings for lower cards.


i have a sapphire 7790 oc edithion 2gb mem running at 1050 core clock and 1600 memory and i get betweeand 119 and 122 khs using vert kev miner 0.5.2 here is my config file

,
"rawintensity" : "3583",
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "4479",
"temp-cutoff" : "85",
"expiry" : "30",
"log" : "5",
"queue" : "0",
"scan-time" : "1",
"device" : "0",
"shaders" : "896",
"scrypt-vert" : true
}

if i used any other settings the most i got was between 10 and 15 khs and took me awhile to find that this was the best i could do,,,,my bat file looks like this

@echo off
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
COLOR 0C
timeout /t 4
vertminer.exe -g 3 --failover-only --load-balance

hope this helps you and any other 7790 owners out there, have only just started mining for fun and like a challange with trying all the settings
