I've been getting 1 block a day on a 2 Core Celeron. I wouldn't exactly say that is difficult.

Hmm,
I'd like to see proof of that please.
I've hit it for 3 days solid with Ryzen 1800X and haven't hit 1 block, and 4 days with Ryzen 1700 and no blocks.
What hash rate are you at please? My 1800X gets 200Kh/s

50khs is rate I've been getting on this box.

Hi,

Thanks for coming back to me.

First i must appologise, i was a bit "harsh" with my challenge.
I genuinely didn't believe your figures.
So "Thanks" for proving me wrong, and also for making me re-visit this coin.

Below i have posted all my hashrate...clearly the miner doesn't scale versus threads very well, by the time you get to 8 threads it is nearly 10 down, and once i get away from actual cores to threads only, it get worse much quicker. Most unusual for Ryzen. I was expecting with 16 threads more like 400 kh/s.
Also interesting, these are for my 1800X, the 1700 figures are exactly the same. (within margin of error).

"cryptonomicon25". I have no idea how you are getting 300 kh/s, i can't get that on either PC even O/C ed. That's pretty impressive.

One think i have done though, since i had zero blocks (yep, zero from either machine), i have deleted the wallet and roaming on the 1700 PC, re downloaded the wallet from 1st page, and started from scratch.
Since your posted 10 hours ago, that PC has now found 1 block. The 1800X i have left on the original files and still no blocks.
I will leave it like that for 48 hours.
I am wondering, if the wallet has perhaps been recompiled since day 1, or if i just had a bad install (strange it would be bad on both machines).
So this way i will be able to see if 1 PC starts to dramatically out perform the other.

So all said, looks like we could really do with a more optimised miner.
Thanks for making me engage my brain

Ryzen 1800X hashrates (stock) 16GB DDR4 1600 MHz

1 thread - 34 kh/s
2 threads - 68 kh/s
3 threads - 103 kh/s
4 threads - 136 kh/s
5 threads - 171 kh/s
6 threads - 204 kh/s
7 threads - 238 kh/s
8 threads - 250-260 kh/s (34 kh/s * 8 = 272 kh/s)
10 threads - 260-270 kh/s
12 threads - 270-277 kh/s
14 threads - 280-283 kh/s
16 threads - 280-286 kh/s

if you look at your hash - the drop is significant after 8 threads. that's usually how ryzen behaves - yours has cpu 8 cores and enables more threads through hyper-threading. most algo hashes are correlated to cores and not threads

I realise that (like i said not an issue with most external miners), but its the fact that i have had 2 pc running 4-6 days at 260Kh/s and not mined 1 single block.....until i re-downloaded wallet
