Rip5, first off I hope I'm not the first to say: WELCOME TO OCN!
Using a Antminer U1 with BFGMiner (CGMiner will work fine as well) at the frequency speed of 881 (Mhz) I got a 1.88 GHs average on my PC, I'm slowly upping the core clock from stock again on the raspberry pi (hopefully getting to that on Monday). I will slow and steady (a.k.a. carefully: something new to overclocking (I kid, I kid)) raise my core clock and post ALL of the meaningful and helpful stats/tips I find from this project. So yeah! On Monday I will hopefully get the new thread up and running, I'll link to it then, and I recommend following it because "What could go wrong?" (everything)
