Tonight was the first night I had time to work with my new R-Box since last weekend. Using 4.7.1 it has been running around 91 GH/s cgminer, but around 73 GH/s thanks to a nearly 20% error rate. (I previously thought my errors improved when I moved to GHash, but I just wasn't accustomed to their different way of displaying errors). I get these results at pretty much any frequency.

I tried 4.8 today and, at first, I was thrilled with the results. At 270-290 MHz I get only about 2-3% errors, which is fantastic. It runs in the low 80's GH/s, which means slightly better results than 4.7.1.  However, after 10-15 minutes it will tank down to about 40-50 GH/s. I have no idea why it's doing that, but it only happens with 4.8.

Tomorrow I'm going to try using my laptop in case it's something to do with my computer. I tried BFG briefly, but couldn't get it to find my device. I'll give that another shot tomorrow, too.

(please take all of this with a grain of salt, as I'm very new to ASIC mining)
