I had great results few months ago, making hynix to have elpida performance in few algo, + hynix had an even great performance with my own custom latency numbers.
I've gotten over 900H/s stable on XMR with my 470 4G - so yeah, it's pretty nice.
I assume thats overclock + custom timings?
Whats best rate on underclock/undervolt + custom timings?
