Monero Mining

Why, hello, fellow deviant. It is I, Dark_Armadill0. I've done two major recent changes, and now find myself troubleshooting/opinionating my situation. Buckle up, Spanky, it's a long read, but I want to give helpful details to get helpful answers back from you.

1. I upgraded Ol' Bessie from an AMD Phenom X6 (hex-core) AMD 1055T and built a new system.

CPU: AMD Ryzen 9 5950X processor at 3.7GHz (no manually over/underclocking done)

RAM: G.Skill 32GB CL14 running at 3600Mhz natively

Mobo: MSI MPG X570S Edge Max Wifi

Drive: Samsung 980 Pro with Heatsink NVME M.2 SSD

Ol' Bessie was mining at 534 h/s on a good day on the 2011 PC build. Henceforth, my computer's name will be referred to as Mone Risa. Mone Risa was mining at 18534 h/s before I tried my hand at overclocking and had to reset the CMOS to clear the BIOS and default the system. So, last week I restarted Mone Risa and my hashrate, for some inexplicable reason, dropped to 16337 h/s (pictured). I'm wondering if the hashrate will bounce back, or if something on the network (say, difficulty) changed and my new 16337 h/s cannot be improved?

2. I've been mining on Mone Risa using XMRig 6.xx with 1GB Hugepages successfully enabled on my Linux OS... and from what I can tell from XMRig's startup preamble, the hugepages are running in XMRig as well. I am mining on xmrpool.eu:9999 pool, which is super close to me as I'm in the same country as that server. I've been mining for about 2 months now, and have 0.00000000000 XMR to show for it. Since I'm mining with a pool that has a payout at 0.07 XMR I'm kinda disheartened to see absolutely nothing. Haven't received any shares of block rewards. Is this normal?

Thanks in advance, and thank you for using Lemmy! I'll see ya in the trenches.
