Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt --intensity 17 --worksize 256 --lookup-gap 2 --thread-concurrency 22528

630kh/s on Gigabyte GV-R795WF3-3GD rev.1 (Catalyst 13.4)

Could try more aggressive settings, but VRM temp is too high (95 C).
My record is 700kh/s on this card with Catalyst 12.8 + AMD APP SDK 2.6 with "--intensity 20", but VRM temp was going to 120 C.

"intensity" : "20,20",
"worksize" : "256,256",
"gpu-engine" : "0-1040,0-1040",
"gpu-memclock" : "1480,1480",
"gpu-threads" : "1",
"vectors" : "1,1",
"lookup-gap" : "2,2",
"thread-concurrency" : "21712,21712",

these are what i use for 620kh/s

Code:

Maximum buffer memory device 0 supports says 805306368
Your scrypt settings come to 1422917632
Error -61: clCreateBuffer (padbuffer8), decrease TC or increase LG
Failed to init GPU thread 0, disabling device 0
Restarting the GPU from the menu will not fix this.
Try restarting cgminer.

I get this error on cgminer when I try your settings.
Also I am running two MSI 7950's

execute command

Code:

export GPU_MAX_ALLOC_PERCENT=100

Thanks for your answer.

I currently get 550KH/s per GPU.

sig threads

guiminer-scrypt 7950 high usage settings

Is there a Linux version of guiminer-scrypt?

No, in which case use the cgminer settings in the other thread in my sig, just don't forget to run "export GPU_MAX_ALLOC_PERCENT=100" first

Hi,

Recently I setup a rig with 2 7950's and I plan to mine litecoins with them due to being more profitable than bitcoins.

Please can someone share their cgminer configuration for 7950's

EDIT: I am using Linux
