Best software for 2 Antminer U1's? And overclocking?

[kadrek]

I ordered a couple of Antminer U1's just to play with and I'm wondering what mining software would be the best to use. Is there a good guide on how to set them up?

Also, in the amazon review by DJ Knight he says he was able to overclock them to 2.5 GH/s using AntGen. Is that not safe as they only say to overclock to 2.2 GH/s? And where would I find the newest version of AntGen? Or should I not use it? Here's the amazon page, http://www.amazon.com/Bitmain-Antminer-Block-Erupter-1-6Gh/product-reviews/B00HIUIGDI/ref=dp_top_cm_cr_acr_txt?showViewpoints=1

Thanks for any help
