JCE-Miner, I'm running now the miner in my 2nd Ryzen. Is a Ryzen 5 1600 at 3.75GHz, RAM at 2933.
Is incredible! 2KH/s (just 10% less than R7 1700) mining CN-Lite V1
It's the --auto tuning the best optimisation so far to R5 1600?
Im getting quite consistent over 2KH/s with my Ryzen 7 2700X for mostly any cnlite variant with the following config:
"cpu_threads_conf" :
[
{ "cpu_architecture" : "ryzen", "affine_to_cpu" : 0, "use_cache" : true, },
{ "cpu_architecture" : "ryzen", "affine_to_cpu" : 2, "use_cache" : true, "multi_hash" : 2, },
{ "cpu_architecture" : "ryzen", "affine_to_cpu" : 4, "use_cache" : true, "multi_hash" : 2, },
{ "cpu_architecture" : "ryzen", "affine_to_cpu" : 6, "use_cache" : true, "multi_hash" : 2, },
{ "cpu_architecture" : "ryzen", "affine_to_cpu" : 8, "use_cache" : true, },
{ "cpu_architecture" : "ryzen", "affine_to_cpu" : 10, "use_cache" : true, "multi_hash" : 2, },
{ "cpu_architecture" : "ryzen", "affine_to_cpu" : 12, "use_cache" : true, "multi_hash" : 2, },
{ "cpu_architecture" : "ryzen", "affine_to_cpu" : 14, "use_cache" : true, "multi_hash" : 2, },
]
What i basically did was to look how large the scratchpad is for cnlite (2MB) and tried to use as much of my CPUs cache for the scratchpad, thus the 6 cores doing "multi_hash": 2
I think that a ryzen is quite good for cryptonight, bad for cnheavy but exceptionally good for cnlite.
Hope this helps you to maybe squeeze a few H/s more out of your ryzen.
