I had a headache with my three ASICMiner Cubes (each 30GH/s to 38GH/s (overclock option)), and want to deal with them. If anyone wants it: 0.6 BTC/ea, or 1.5 BTC/all. (I bought 1BTC/ea in December).
I don't see any malfunctions in the cube. They just work great with the specified hashing rate. The following are what happened. If you are interested to them, just PM me or send me an email (
joescgm@gmail.com). You can also give me an offer if you want. I am seriously dealing with them and will definitely deliver them to you.
The thing with them is that some of them randomly shut off, but if one runs standalone, it just works fine. Initially I used "Cooler Master Silent Pro Gold - 1200W Power Supply with 80 PLUS Gold Certification and Semi-Modular Cables" to power them. After some time (two weeks or so), one of them stopped working (plugging in and out just makes it work again). After searching online, I decide to buy another power supply, which plus the old supply did support them properly. However, an incident happened recently when I swithched the new power supply with another as I need to use the new one for other purpose. After this, however, some of them repeat the same problem. Even now the Cooler Master Silent Pro Gold cannot support two at the same time. This is very weird to me. If the supply powers up two at the same time, both last for some time and then one (randomly) stops. I got an impression that my power supplies become deteriorated. When they are running, no "x" in the row on "Chips" in the web interface show up. The hashing rate is 30GH/s and can go up to 38GH/s when overclocked. So I am pretty sure they are working, maybe due to the settings or the subnetwork, etc. I just don't want spending time on them. If you want, I can also get the power consumption when I have access to them. Let me know if you have any questions. Thanks.
