Great to hear! Let us know how you do with the TX850.

I have 2 cubes also, running off of a Corsair TX850M. I have read that you want your PSU to have a single 12V rail rated for at least 50 amperes if you're looking to overclock two cubes at once. Mine has a single 12V rail rated at 70A, I see yours has six separate 12V rails rated at 38A each. Even though your PSU has a higher wattage rating than mine, this could be an issue. I can OC both of my cubes just fine with my Corsair.

Something else to look at - is your PSU plugged directly into the wall, or are you going through any kind of UPS? I briefly had mine plugged into an APC Backups 1500 because of some frequent power outages and brownouts I've been experiencing due to an ice storm here. Couldn't OC for nothing, could barely hit 30 Gh/s. As soon as I went back to being plugged into the wall outlet directly, I could OC my cubes again.

I would unplug one of your cubes, just run one and see if you can OC it still. If not, then try a quality PSU that has a single 12V rail that can handle a sufficent amount of amperes. Good luck!

Same here, I agree with HellDiverUK, if longpoll support could be added to BFGMiner that would be awesome. Thanks for all your hard work on this program Luke-Jr, I enjoy using it.

<--- yet another newbie to the forum

Been reading the forums here for a bit, ready to start contributing to various topics, especially the mining section. So hello! And hope you all have a happy new year.

It's not just BFL products. The ASICMiner cubes and blades have been dropping also. Especially the cubes, by about 25%
