What I mean is each board is tested and working great. The problem appears to be with my USB Hubs, or my power supply.
- Hubs malfunctioning
- Hubs have minor compatibility issues causing stability problems when used in conjunction with the chip on the icarus
- Power supply is not putting out clean enough power to keep them stable under higher load
(or some combination of the above 3)
All 16 worked perfectly for a couple weeks, now I can only mine on 12. (I had a loss of internet connectivity, which prompted me to reboot the host machine, after that the problem started, I don't believe that was the cause, I believe the problem was present all along, and the reboot simply "triggered" the symptoms).
I have since tested every board for longterm stability, they all work fine, in groups up to 12. But when I exceed that number it fails. It also fails if I exceed over 6 boards on a single hub (which leads me to believe it's the hubs).
But I've already replaced the hubs in the past for a similar issue, and these new hubs seemed to solve the problem for a couple weeks, then it randomly came back. Also when testing in another machine (12 in one machine, 4 in a second machine) the problem still surfaced. Using completely different hub for the 4 "outside" boards, but they were all still driven from the same PSU, leading me to believe the PSU is at fault.
I am spending a lot of time right now narrowing the problem down in my system, so I want to simply scrap it and start from scratch in order to nail down this niggling systemic issue.
I'm 99% sure it's one of the other components in my system. As I said each individual board works perfectly, and any combination up to no more than 6 per hub, or 12 in total will mine fine (and have been now for over a week without problem). so I know the boards are 100%.
I don't have the funds right now to replace every other component in the system, and replacing only the hub for example doesn't seem to completely help, leading me to think it's a combo of multiple parts in the system. If I sell these off, buy an alternate, and buy new components to start from scratch I will save myself a lot of time and aggrivation.
Does that help clear it up for you?
Also No worries about not being from the USA, neither am I (I'm in Canada).
But, shipping will likely cost more if it's going overseas, so let me know via PM what your address is and I can estimate shipping, then we can settle on a possible price.
