Just a note for miners.

i have two rigs with identical 3rd gen AMD's, and 4000Mhz ram, one with CL18 Hyinx, and one with CL15 B-die.  Both overclocked cpu's and ram via secondary timings.

The CL18 is hashing the argon2/chukwa ~64kH/s
The CL15 is hashing the argon2/chukwa ~54kH/s

So far, the looser timings are wining with the argon2/chukwa algo. I have no idea why?
