I got my repaired board back on this past Sat and have finally been mining with it for the first time. (I was away both in early Dec and Xmas, so shipping times screwed me around. Angry

)

I've been using CGMiner 3.9.0, built myself on Ubuntu 13.04, and experimenting with settings. I've noticed that the board really seems to take awhile to hit peak processing speeds. I mean like 15 minutes before the 5s avg reported hash rate gets over 20GH/s. Is this normal? Is anyone else seeing it?

I'm also getting HW errors over 10% even when using a shielded alternative USB cable. For example, my latest run (int:52:2:950) has been going on for 70 minutes and the CGMiner reports:

Code:

DRB 0: E8 34 max 34.8 | 22.60G/19.87Gh/s | A:18954 R:24 HW:2233 WU:277.4/m

Do I just have a poorly hashing board or is it possibly related to the repairs? Milkbottlec reported having to resolder things a second time to get an acceptable hash rate, so perhaps things still aren't quite 100% there?

Those hashrate seems good you can also try 53:2:950, us cgwatcher to monitor. you must have fan(s) on the heatsink and also a fan on the other side also helps
