Could you have underclocked it more? How is the noise level at those settings? I can't find a proper review of these anywhere...
The only options available on the web interface are 800/1000/1100/1200Mhz.
The higher I put it, the more errors I see.
Don't expect a review, they are not worth the effort anymore.
A X3 produces ~us$1.8 a day at current difficulty while using ~20kWh (@230V) of electricity per day at the lowest offered speed.
BTW, the VAT invoice also came in, another us$200 down the drain.
