I have the following settings on my 2xGigabyte 7950s setup (I got a couple of cards n the shop):
./vertminer -o startum+tcp://stratum.vertco.in:8080 -u -p x -I 13 --thread-concurrency 14777 --gpu-engine 1050 --gpu-memclock 1500

these are the best settings I can get without getting HW errors and all I get is a whopping 327 mhs Angry

!!!!

Apparently everyone has r9 280x now, so I have been having a lot of trouble trying to get better settings around here Undecided

Would be awesome if more people published their configs for 7950s

Cheers! Grin

That's not bad. Remember hashrate is half of normal scrypt. Going to try your settings as mine (posted some 20 updates ago) got me a good 250Khs on HD7950's.

I'm getting 163.5 khs per card! not 327 hashes each ! I used to mine @ ~650 dogecoin so I am currently mining @ 1/4 of the normal scrypt currencies :-/

That explains why I couldn't get it to work properly.

My HD7950 (XFX's) config again, for 250+ Khs each:
./vertminer -o blabla -u aa -p bb --failover-only -I 19,19 -w 256 --thread-concurrency 16384 --gpu-powertune 5,15 --gpu-engine 1110 --gpu-memclock 1500 --gpu-fan 30-90 --auto-fan --auto-gpu --scan-time 30 --temp-cutoff 90 --temp-overheat 85 --temp-target 80 --api-port 4028 --api-listen --api-network --api-allow W:192.168.1/24

Weird! I get a TON of HW with your settings. Guess I'll be sshing from my morning classes to get a clean install going and give it another try

actually . . . what is your mining rig setup? Maybe I'm lacking memory or something?

I'm running Xubuntu 13.10 from usb stick and use 4Gb RAM on Asrock Extreme 4 motherboard and sempron 145 cpu. 2x HD7950 (XFX DD and XFX DD Black) and 1x XFX R9 280x.

Also using AMD SDK 2.6 and (I think) 12.8 AMD Drivers. Forgot which version I used though.
