Thank you so much for your help!!
Will try the command line first as it is the easyest way to do it ;-)

Could you please tell me ho you OC them ?? A short step by step would be cool!
Thanks!
There's a lot of good information here:Could you please tell me ho you OC them ?? A short step by step would be cool!

You can find information on the specific settings in their github ReadMe:
https://github.com/AntMiner/AntGen1/tree/master/cgminer
The updated USB to UART drivers can be found here:
http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx
The latest BFGMiner has support built in for this miner:
http://bfgminer.org/
There are a lot of ways to overclock the device, but the easiest is to change your command line parameter, and make sure you've got enough airflow on the device.
default command line example:
Code:
bfgminer -o stratum+tcp://... -u ... -p ... --set-device antminer:clock=x0781 -S antminer:all
You overclock by changing the clock variable according to the settings in the readme. 0781 is the default clock, 0881 is a moderate overclock (from 200Mhz to 225Mhz). 0981 appears to be the typical stable overclock (from 200Mhz to 250Mhz) without additional cooling or soldering on new parts to change the voltage. 0981 took my units from 1.55GHs to 1.96GHs each.
Hope that helps. The rest is trial and error.

I've purchased 2 from iluvpcs (one of the links above). Each order was from a different batch, and they both perform well and identical. I've had the best luck using bfgminer 3.10.0 with these devices. The only catch is, you need to download and install the SiLabs driver update to make them work reliably. I haven't attempted to push them, but I was able to painlessly overclock them to 2.0 with nothing but a change in the command line setting.
They're not a bad piece of entry-level hardware.

I manage to oc to 2gh/s using x981 in bfgminer, 2.2 got a lot of hw error
bought a few from taobao for RMB 350 ... but after 14th Jan , some seller no longer sell in their store due to taobao policy ...
May I ask where to buy them? And what is a good price?
bitmaintech.com shows 22 BTC per unit...

And Minersource shows 0.07.22btc for a box of 500.
I have found my pc's don't like to run more then 45-55 sticks of ant miners.
But they run those numbers very well. I have 48 sticks right now on one pc running at a 2.0 over clock and getting around 93 gh.
I don't know where you live USA price now is about .053- .055 a stick and a little more to ship.
if you want a few of them,

Thanks! To be exact, they can be simply used with CGMiner, correct? And how much hashrate do you get from 1 overclocked unit?
They work with BFGminer now too starting with 3.10.0

right now I am running 38 sticks out of a 49 port hub and 10 stick on a 10 port aitech hub. a total of 48 sticks and I am getting 94.5gh out of 96 gh.
the ant miner sticks are the best stick for the price. no stick is as cheap per gh.
I did a lot of testing and have found that a 2.0 gh overclock is pretty easy.
The only catch I have found so far is the antminer literature says you can do up to 120gh on 1 cgminer fork/program. that would be 59-61 sticks at 2 gh.
I seem to crash at 52 sticks. but at 48 sticks I am really stable.

Can the ant miner sticks use stratum? or are they stuck using getwork
yes I use btcguild and bitminter
