how much high grade ram do you think the controller will need? 8gb of ddr3 or 4gb of ddr5. the controller will cost $$$$. So the s-5 will not be 340-370 it will be 440-470. A shit coin can have 10000x the shares of a bitcoin.
BTW I would like a better controller myself. Maybe a new quad core rasp pi x 2 has enough to do it.
It appears you're throwing numbers around. I don't know what memory the S5 is using now and I don't know what the actual problem is. Perhaps it's a little early for your speculations? Let's see what Bitmain has to say and try to avoid speculation!
I have a feeling that its to do with westhash and generally altcoin mining as a frozen controller isn't a typical error we see. What could be happening is that on coin / block / whatever change, its flooding the controller with inappropriately low difficulty shares which is causing it to lock up.
Do we know that the described Difficulty issue is a known controller lockup cause? This is not an attack, it's just not clear Bitmain has described what the misbehavior might be with a difficulty mismatch. My view of this issue is obviously going to be different between a compatibility problem with Nicehash/Westhash Vs a generic problem. If it is a compatibility problem, I think it reflects back on Bitmain to try harder to match their products to real world product usage. My intent is to purchase a general purpose SHA-256d miner, not an exclusively BTC miner! Mining is just too expensive to be limited to BTC.
Well, philip is right. It doesn't matter how much resources you give a controller, if you try and use it inappropriately it will still fail to do what you want it to. This controller is designed for something around 200+ difficulty shares at the lowest, and even that will likely start throttling. If you're pool, coin or whatever else is throwing significantly lower difficulty shares at it then there's no way its going to cope, regardless if you gave it more resources and made it more expensive.
The best analogy I can come up with is like trying to dump a swimming pool's worth of water into your bath, then complaining to your landlord that he hasn't given you a big enough bath. There is nothing stopping you from mining other coins or on other pools, they just have to be sensible.
