Miner- [NiceHash] Zcash CPU/GPU for Linux and Windows

Mining
375

@nicehashdev why it is so slow on a server with 32 cores. I got only ~30 Sol/s. Any Ideas?

You need to launch two miners with nodes set, read my posts above.

377

Is that 32 cores or 16 cores with HT?

378

That are 2 sockets with each 16 cores = 32 cores BUT vCores as you can see on the screenshot

379

When I look up your processor it shows 8 cores per CPU, but it has HT so it can do 16 threads per CPU:

Like nicehash said though, make sure to launch a miner for each physical processor

I am getting this error, can someone help me please? (drivers are updated, my card is a GTX 550 Ti, windows 7)

381

Damn, now I have to wait for NH to release the source, then port the large number of optimizations I already made into the new versionā€¦

382

What command line you used to run it?

383

nheqminer.exe -l usa -u 1HeoNYBcW1o3qee45NnvtTR9o5M6pEqEJn.worker1 -t 4 -cd 1

384

Try with -cd 0

If you only have 1 CUDA device, then it is 0.

385

Oh, thanks, i forgot that :sweat:

386

I canā€™t get the idea of nicehash.com

Correct me if I am wrong:
If I just use your miner then I am not doing mining Zcash actually but selling my hashpower for Bitcoins.
Is this right?

Thanks!

387

''Try with -cd 0

what if you have 2 CUDA Devices?..

-cd 0,1

?

Almost 17 Sols/s in I5-2310 @2.9GHz + GTX550Ti + 4GB DDR3 1333MHz on windows 7
Only witht he I5, I get ~11Sols/s

-cd 0 1

-h will print you an example

I have some confusion regarding mining on hyperthreaded CPUs on bare metal. If I have a 10-core Xeon with hyperthreading (20 threads), should I be launching the miner with -t 10 or -t 20

391

for my understanding two instances with -t 10

392

Is it single CPU? If yes, then launch with -t 20, but also try lower number of threads to see if you get better performance.

393

Thank you nicehash, 32 S/s with a GTX 1080 =D

394

Thank you. had -cd 0,1.
