So now in the change of pools to utc.tumblingblock.com and utc2.tumblingblock.com, can I get clarification on what port I should use when using Yacminer.
I am using port 5555 as stated in the pool's notice until told otherwise
If your miner have quite low hashing speed, so that it may get under 1 pool difficult, least then use port 5555. (European pool have also port 3334 what have variable diff but limited so that it do not drop under 1. )
I have connected my some rig with yacminer what have around 17khash/s to port 3333. I can not see problem in this case. This kind of rig (one 17kh/s worker) get always over 1 pool difficulty and if I have understood right it is ok) Previously I run small tests with small miner (1x and 2xR7 240 4Gb) and there was problem because pool (port 3333) drops its pool diff under 1 soon after starting.
There is not good and enough deep explanation about this Yacminer problem what it is exactly. But least this I have seen that under pool difficulty 1 there is problem to count accepted shares.
It is perhaps useful also look what information now or later can find from YAC coin discussion because there problem is perhaps more wide due to much lover hashing speeds (due to N value 16)
