I can't find right settings for 7990

LittleOrion

Hey @ all
My Problem is i have a 7990 running only at 400 KHash with the 2 GPU’s together. That’s very low :/ i’ve already the best settings in my scrypt it looks like this:
[code]cgminer.exe -o stratum+tcp://pool.d2.cc:3333 --scrypt -u ****.**** -p 123 -I 13 -g 2 -w 256 --thread-concurrency 8192
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1 [/code]
So what did i wrong? Has anyone here a 7990 who could help me out? I’m new to mining so sorry if i did something wrong.

try this:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt --shaders 4096 --thread-concurrency 8192 -I 13 -g 2 --worksize 256 --lookup-gap 2 --gpu-vddc 1.170 --gpu-engine 975 --gpu-memclock 1200 --gpu-powertune -15 --temp-cutoff 102 -o stratum+tcp://nl.nut2pools.com:5545 -u xxx -p xxx

This gives me 1330Khash on my Asus 7990 (standard cooler)

Note it WILL overheat inside a case if you don’t have door off or proper air circulation

thx :D i will try it when i’m finished with work :P
EDIT: The Case is for the moment open cause i don’t know where to put the watercooler from the H100i
But thx for the tip i will put that monster near of the window :)

sorry for the double post :/ but i’ve changed the settings and still at 400 KH… maybe the pool is slowing down or something like that? i’m mining in the d2 pool. And the 7990 is a Club 3D

400khash? please post screenshot of gpu in cgminer, i suspect that third party app is lowering settings on the card.

Expand the window larger and then press G
