I need some advice / assistance.
I have one of the first batche pairs of rk-boxes that are supposed to do ~900GH, but over the past 2 months ive only gotten ~650GH on average for a few reasons:
1) I regularly see intermittent periods of downtime, or it needs a reboot because it keeps doing software reboots every 5 minutes
2) it will only recognize 5-7 boards of the 8, usually only fixed with a power cycle.
3) even when running fine, its about 880Gh with 7-10% errors.
Ive upgraded to a class 10 SD card after a recent power outtage killed the class 4 (please stop shipping class 4 cards for mining equipment - put $3 more into a class 10 that will survive power cycles), but its had no effect on the stability or mining results.
What can i do to fix the problem? Its a massive pain in the ass because this unit is both my least power-efficient and the most irritating to fix.
Are there any ways to reduce the W/GH? has anyone tried undervolting to get <1w/GH?
i got same results after 1 months
board dropping, reboots etc
i decided to change psus
i got deus650 and bequiet 630
after swapping into couple of xfx850w problems went away
so maybe thoose psus got worn off or something
i dont know
i got rbox r3 and r4, very dissapointed with r100 program
i got no new miners
i paid 2.5 btc deposit for 1th, paid at half of july, got miners after 3 weeks... at aug
with bent components, terrible packaging
no compensation, no response at email, no new miners
i am at big loss...
1. Those 2.5 BTC is just the guarantee, you should read carefully about the R100 PLAN, not the price of buying miners!! when the plan is end, you can send the miners back to us or take it by discount, we will refund BTC to u!!! What R100 spot name?
2. For miners performance problem,we are trying to improve it , if you contact us once without response pls contact twice, Alex signed his private number on his email, if you feel it's a big problem you can call him too.
1. I read it carefully. I asked in this thread when project will end or when new miners will be shipped. No response. I asked by email 2 times about new miners and other stuff. 0 response. My spot ip is 192.168.2.223. I will try contact alex again.
2. After swapping psus 1 day they were hashing stable and now 2 boards are not hashing, rest is underpefrorming, i got 414 GH instead of 900GH
