I've been unable to get the New R-Box running on Mac OS 10.9.5. I made a [still in the queue since Nov 2014] comment on nwoolls' blog about this, but since the comment was never approved, nobody has been able to see it.

I have two New R-Boxes and they run fine in VMWare Fusion running Win2000. I'd like to not have the overhead of always running VMWare Fusion though. I've made certain any and all USB drivers have been removed for Silicon Labs. And running nwoolls latest homebrew of 4.8 [even though the New R-Box will not run well on versions of cgminer greater than 4.7.1 - i posted a separate thread about this, but it hasn't been resolved - one unit will get 100Gh/s and the other 55 with 4.8.x or 4.9.x].

Anyway, as you can see from the screen shots, cgminer does see the 2 valid USB devices, but when running them with

cgminer -o stratum.mining.eligius.st -u <my wallet> -p nothing

I get errors seeing the USB devices.

Any tips on making this would rock! Thank you!

I decided to run 4.9.0 for a couple of hours and what's happening seems to be that one New R-Box is running at full power, and the other at 1/2. Before both would be much closer to 100Gh/s. I've inserted a screenshot.



Any idea why this might be happening?

Thanks again!

Hi there,

Thanks for the info! So far my reject rate is 0.15% so I'm not sure that is the cause. I would expect to see "(duplicate)" 1/2 the time with a 50% rate deduction and I rarely see more than 1 "duplicate" show up in the line-by-line transactions. Is there any way I can get a look at the exact stats for how many duplicates that are produced?

TIA

Are there known issues with the New R-Box and CGMINER 4.8.x and 4.9.0? I ask because both versions perform worse for me than version 4.7.1. With 4.7.1, my 2 New R-Boxes get 97-110 Gh/s and with the 4.8 and 4.9 versions, they are getting nearly half of that [about 55-60 Gh/s each].

I deleted 4.8.x but I still have 4.9.0 installed [Windows XP] as well as 4.7.1, if there are some ways I can help debug to find the cause of the slowdown. Would be more than willing to do whatever I can so I can get on the latest release with the "usual" speed that 4.7.1 has given me.

Thanks!
