Re: [850 TH] Slush's Pool (mining.bitcoin.cz); TX FEES + VarDiff

I have been running 5 antminer u1's for 2 or 3 weeks now and I have a USB fan to cool them. When I started using them I noticed based on the site for the pool I was getting about 7 to 8 Mhash/s. Now I'm getting just over 6. Is this due to difficulty going up or do I have a miner about to fail?

Hello
I'm running 6 U1's and used to get 12gh/s (11.95/12.03) for weeks and suddenly i get 11.30 at its best...
They are easy to overclock up to 2gh/s, easy ans stable.

Where does this drop come from, deeply thx guyz.

Try this for a bat file:-

bfgminer.exe --set-device antminer:clock=x0981 --icarus-options 115200:2:2 -o http://stratum.bitcoin.cz:3333 -O worker:password -S antminer:all

You kind thx buddy.
I used a Command .cmd as
c:\bfgminer\bfgminer.exe -o stratum.bitcoin.cz:3333 -u xxxworker1 -p password -S antminer:all --set-device antminer:clock=x0981
where do I put this "icarus-options 115200:2:2"

Got a clue why do i lose 5/6% hashing power, so strange.
