gigabyte 7770s

trying to get anything close to 200kh out of my 3 gigbyte 7770s.


anyone have cgminer settings for the 7770?

Here's my config file. It's an HD7770 with a gig of ram. cgminer version 3.7.2 on Windows7 64bit. 8Gig of ram and a bulldozer 6 core.

color 17
setx GPU_MAX_ALLOC_PERCENT 100
setx GPUUSESYNCOBJECTS=1
cgminer.exe --scrypt -u username -p password-o stratum+tcp://coinotron.com:3337 --gpu-platform 0 -d 0 -g 1 -w 512 -I 17 --thread-concurrency 8000

This runs at 195Kh/s with a WU of between 170-180. I've tried various worker sizes and clocks and intensities, but these settings appear to be the best for me. I get zero HW errors and 99.5%+ accepted.

Clocks set at 0.71 ratio of: Core - 965Mhz Memory - 1360Mhz

I set the fan to run at 100% as this runs pretty warm hovering around 83C to 85C though I could probably improve airflow in the PC as I've a side mounted fan not in use at present. This is using the latest CCC

Here's a very short sample:
