that its more stable, or no disrespect meant ?

That it's more stable. My U1 miner has run for a month without a problem on cgminer at 2GHash.

Hi, i would like to get help running my U1 at 4GHz ... the code that i had was " --bmsc-freq 5381 " but it seems that the latest version of cgminer dont support this command... can anyone confirm this? Huh

If so... how will i get 4 Ghs hashing from U1 Antminer?

GroundZero

That command only ever worked on a fork, not my official cgminer. Cgminer uses the much more intuitive actual frequency in MHz for its commands with the command

Code:

--anu-freq Set AntminerU1 frequency in MHz, range 125-500 (default: 200.0)

Note that unless you have hardware modified your U1 and have some way of providing it much more power than USB normally provides, there's no way it will give you 4Ghash, but if you somehow did, that would correspond with a frequency of 500MHz.

I use BFGminer, my .conf file has this in it :

Code:

"set-device" : [
"antminer:clock=x0A81"
]

I have 3 of them at between 2.12 - 2.22

When I first start BFGminer, it does not see them, so I hit "M" and Then "+"
then type:
antminer:all

it see's all 3 and they start hashing and Quickly jump up.

Within my pool, I have the worker set at 8 difficulty (for 3x U2 sticks), and that forces them to do more

Try the official version of cgminer which has much better support instead of those outdated forks and doesn't take those confusing command line options, just a single frequency value with --anu-freq 250 (for 2GH).

I'm mining with an Antminer U2 in cgminer at 1.6gh/s. However, with the frequency set at 0981 I should be getting 2.0 gh/s. I'm using a powered hub providing 5v/3.5a and have the unit properly cooled with an Arctic Breeze fan (powered separately). I also have two bock erupters I'd like to run simultaneously but don't know how to accomplish this. Here is my .BAT for the Antminer:

Code:

cgminer.exe --bmsc-options 115200:20 -o stratum.btcguild.com:3333 -u worker -p pass --bmsc-freq 0981

Any help is greatly appreciated.
