Re: ROCKMINER ASIC miner official thread

I've got a Rk-Box, and I wanted to make sure I have done all the tricks. I have never gotten it below 10% error rates. It seems other people have higher hash rates than I do, and that's kinda frustrating. I've used rockminer's cgminer and tried their raspberry pi image, changed around frequencies, and I even replaced their USB hub with my own (no difference). Here's what I get:

300M Freq: 456 Gh/s, 11-12% error for ~405 Gh/s poolside
320M Freq: 478 Gh/s, 17-20% error for ~395 Gh/s poolside
350M Freq: 475 Gh/s, ~14% error for ~405 Gh/s poolside

I've played with it for a week now, and haven't gotten better. Anybody with better specs have any additional tricks? Or did I just get a poorly performing box?

What Firmware are you running? If you are on the most recent, you should be seeing less than 5% rejects and ~475 Gh/s avg.

My RK-Box R-Pi seems to be rebooting daily as well. The timer was up to about 16 hours last night...back down to 5+ hours this morning Undecided

Well ive been running mine for about 14hrs and I worked out hardware rate to be around 16%.
Formula I used was 100 x HW /Accepted shares. It seems to be averaging 460 - 480GHs with the 320 setting.
How do I check which firmware the RK box is. Ive got it connected directly to pc and not using a pi at all.
Any help would be appreciated.

I'm not sure how to check firmware on windows. I was under the impression firmware is only for raspberry pi linux using the WebUI.

Why did you do 100 x HW in your formula?

Let me know how you make out.

Funny thing... I've switched raspberry pi's and now all I keep getting is failure comm errors on this new RPI Sad

Boards go zombie then they kick back in on cgminer.

change the usb cables, and/or the usb hub. I was getting similar errors, and I solve it by changing the usb hub.
