I just got my Antminer USBs and they run at 1.6gh/s on default settings. They're intended to run at 2.0gh/s, so I'm trying to overclock them, but oddly, trying to overclock actually slows them down to around 200-400mh/s.
I'm using the custom version of cgminer
here, like so:
cgminer.exe -o server -u username -p password
That gives me 1.6gh/s. But if I try to overclock like so:
cgminer.exe --bmsc-options 115200:20 -o server -u user -p password --bmsc-freq 0981
instead of going up to 2.0gh/s, I get the weird behavior where it slows way down. Any ideas?
I may break down and try bfgminer or something instead, but cgminer has always worked well for me and I'd like to stick with it if possible.
