vertminer.exe -o stratum+tcp://gpu.suprnova.cc:4444 -u Weblogin.Worker -p Worker password

I always got an error " error -4"

I can't seem to get VertMiner (official version) to work...
I get error and GPU disabled as soon as I launch it.

This is my config for a 280x:

What am I doing wrong guys?


Thanks.

Did you create a worker on the pool?
Or maybe you have to check your mail for verification....

and when we know it is a failure or not?

Well it's technically already a successful launch.. since pools are up, no forks, easy enough to get nodes.. difficulty is where it should be.  Just waiting to hit the rewards now...

perfect time to discuss miner settings while reward is so low


setx GPU_MAX_ALLOC_PERCENT=200
setx GPU_USE_SYNC_OBJECTS=1
vertminer --scrypt-vert  -o 127.0.0.1:5555 -u user -p pass -w 256 -I 13 -g 2 -l 1 --thread-concurrency 8191,8192 -Q 0 -s 2 -E 4

so what do you guys change for 280x's this get me 730kh/s each card scrypt. but only 200 and 250 respectively scrypt-n.
changing TC to 8192 for first card gets me 250,250kh/s.

what else you guys try? I hear 350 is very achievable with 280x's

why so few 1 GPUcoin per block

You are running those cards way too hard for that hashrate. I get 386kh/s with memclock 1500 and gpu engine 1080. I also am at 0 powertune and undervolted to 1.1 volts. I am also using Asus cards, more than 1 and they are both the same. You should probably try to lower those settings since you are using a lot of electricity overclocking that much.
