To all those who pointed out my guiminer problem was because I had all three miners pointed at the same gpu, you were right - I was
smart enough to set the GTX 480's up correctly but forgot to check the same when I cloned 2nd & 3rd gpu from my first 7870 miner.
guiminer connects to stratum.bitcoin.cz:3333 ok, and all three are putting out 360+ MH/s.
I gave cgminer one last try with Murf's suggestion:
It is trying to connect via the old getwork protocol over http. try:
cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u [my worker id] -p {my worker wd] --intensity 9
with command line = cgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u [worker id] -p [worker pass] --intensity 9
Same problem, returns the following (tested after the recent stratum stability issue was resolved):
probing for an alive pool
pool 0 JSON stratum auth failed: (null)
No servers were found that could be used to get work from.
Please check the details from the list below of the servers you have input
Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers
Pool: 0 URL: stratum+tcp://stratum.bitcoin.cz:3333 User [it's showing the right worker id] Password: [it's showing the right pass]
Press any key to exit, or cgminer will try again in 15s.
cgminer works ok if I throw in the --scrypt flag and connect to a stratum-based LTC pool, so mebbe something wrong in the 3.0.1 build
I downloaded. For now, I'll be using guiminer.
