hi to all, i'm new of this mining world..

i'm trying to figure out all these things and I still have one question:

is it better to have as many cores as possible or just the half of them at double speed?

i mean.. i have 12 cores on my server, 24 with hyper-threading..

with hyper-threading (-t 24 or blank) i have 24 threads with about 55 k/hash each

without hyper-threading i have 12 threads with about 95-100 k/hash each...

is it better to have a thread working at 100 k/hash or two threads working simultaneously at 50?



could someone help please?

Mathmatically they are the same, but maybe someone else would be able to shed more light on this. I would think that less at 100 would be better because it would be more consistent but I could be wrong.

without hyper you have more mathematical power on the single share (and you should solve it faster and then complete earlier your work)

with hyper you have 2x share to work on but with half power..

think the only way to know is try 24H each and see..

Welcome.

is it better to have a thread working at 100 k/hash or two threads working simultaneously at 50?

It is just the same.

I agree, keep records and compare

IMO: by using single thread with higher hash rate you 'll reach slightly better results ... just tip, I'm not an expert

I would say that 12 cores will be more stable, than hyperthreading with 24 threads.
