I have 6 R-box miners running on CGminer on a Windows 7 machine. They seem to run ok but even running them at a clock speed of 290 I am getting only about 200Gh/s from the 6 of them or just about 34Gh/s each They do peak at about 208-210 Gh/s (still under 35Gh/s each) but only brief peaks. 4 or 5 times a day I have to restart 2 3 or all 6 of the miners as they slow down to high teen to low twenties GH/s
I thought it was power related as I had all 6 running from one 360W PS to start with but I have since bought and hooked up a second 360W PS and put 3 units on each and still the same. I can not get speeds of anywhere near the 35 GH/s each I was expecting with any kind of consistency. I get nearly 35 for brief peaks but it drops off to average a bit under 34 and then drops off to less than 25 after a few hours. I have the 6 units set up spaced out with a 20" box fan blowing across them and they run about 39-40c so I don't think it is heat related either.
My question is, What am I doing wrong or is it just a design flaw that these units can not run for more than a few hours at a time reliably?
Is there an updated firmware or driver I should try? Any suggestions would be appreciated.
What version of CGMiner are you running? Since I have been using 4.4.2 mine has worked really well running at 320Mhz I get 33-35Gh solid.
4.3.3 I will try the newer version and see if that helps. Thanks for the suggestion.
Ok I have switched to CGminer 4.4.2 and it does seem to be a lot more stable. I was running at 300Mhz for 12 straight hours and they were rock solid running around 36Gh/s average each. Thanks for the reply.
Now on a different question What is the range of temps that are safe for the R-Box when running at 300Mhz the temps increase a bit and one of them shows 47c I am just wondering how high is too high is 47c I backed them back off to 290Mhz for now until I find out if the temps are good to go.
