There might be something wrong with my A4 it keeps dropping one board then the other one maybe two mins later it is a B3 i was told and it is running 202 beta it was running ok till last nite then it started doping one board first now it's both, I left the voltage @ 815 like the seller said do and hadn't really done any OC, i swiped out the PSU hoping that was it, both boards are stating to act up ...I really hate to ship it back to china.
I hate this shit of being force to use a old out dated OS on a old out dated rusting PI they sell that is inside the controller that takes for ever to install something that may not install .. man i hope INNOSILICON see the light of this wisdom and let us use our own controller's with Ubuntu 16 in my case the dropping boards may have something to do with the OS and how bad it is and also either give us the cables to run it off any PI hell im even pay for them if that's a problem just make them reason able ...and not some stupid greedy price , I'll make my own once they let us if they let us use any RPI or PI type ......if the price is stupid !!!!
wheezy is old, i don't think even
https://www.raspberrypi.org/downloads/ supports it any more sigh ....I remember reading some place a year ago that support was being drop for wheezy.... upgrade to Raspbian.. i would rather use my own RPI 3 if I have to be forced or limited to a RPI and Ubuntu 16 .... so I may not buy another A4 till they fix the limited controller issue to me that is a big issue and may be another issue causing the boards to drop .....I was giving it some thought of buying another half till the boards started acting up if they are ..EastShore Mining Devices has them back in stack for 899 a 100 bucks more then i paid for this one ...
Don't get me wrong l love the miner the power it uses and small form factor but my Alchemist with 5 working boards and jstefanop firmware with BFG support runs better then this does on most pools, ...IF jstefanop was to write one for this if he hasn't yet i would gladly pay him 60 bucks for a copy .... even 60 bucks a miner if he requested it that's fair to me ...
The sound is no longer a problem for me let it run at full spin i have in a room in my basement that is sound proofed, i may turn into a miner room soon with one window so venting won't be a problem, if i do ...
Last thought for those who don't know the SD card has to be a 8 GIB or less the slot size has to be Class 10 SDHC Card or the big one in this case 8 gib or the OS wont fit it .. and using a big slot adapter with the little standard card won't do it or using a 16 GIB card with SDHC support didn't work for me, i forget that pI only takes one size card slot wise i think and never allowed use any thing over 8 GIB...with that OS ...
I know no one cares but that's how i feel and gonna say it any way ......
