Hi,
I am using Win Vista sp2.
I have 2 Antmine U1 units.
I have the same problem with BFGminer 3.10. and cgminer 3.10.0.
I am now using cgminer 3.10.0, but can only get something like 400Mh/s.
I cannot get cgminer to accept setting freq 0781 settings.
cgminer will only accept --- cgminer.exe -o pool.xxxxxxx.com:xxxx -u xxxx.xxxx -p xxxxxx
cgminer will not accept..
-- cgminer.exe --bmsc-options 115200:20 -o pool.xxxxxxx.com:xxxx -u xxxx.xxxx -p xxxxxx --bmsc-freq 0781
BFGminer will not accept ..
.... bfgminer.exe -o pool.xxxxxx.com.xxxx -u myuser -p xxx -S antminer:all --set-device antminer:clock=x0781
I hope someone can help.
I couldn't find a version of CGMiner that would replicate the issue ( on Ubuntu 12 and re-built with the options for Icarus and other ASICS ) and only version 3.10.0 if BFGMiner will use the extra settings. As an extra note the clock value 0781 is STOCK setting and can ( suposedly ) safely get moved to 0981 for a small increase before having to do surface mount soldering to the power resistors ( by adding 10k to the empty spot and swapping another ). Also, BFGMiner reports faster hashing than CGMiner ( I have 1 with 3 Block Erupters on one system ) reliably. Compared to the pool's reported hash rate, CGMiner seems to over estimate and is slow, BFGMiner seems spot on.
EDITED TO ADD A LINK THAT DOES HELP!
