Hi everyone:

I should admit that I haven't been up to speed on crypto-mining lately. I built my rig a few years back and had it running and do its thing in my basement.

Here's my setup:

- I have 4 (genuine) GeForce GTX 1060 cards, each with 6GB of video RAM. (Bought them on newegg, so I'm assuming it's not a Chinese knockoff.)

- Mobo: ASUS PRIME Z270-A LGA 1151 Intel Z270 HDMI SATA 6Gb/s USB 3.1 ATX Motherboards - Intel

- CPU is: Intel(R) Core(TM) i3-6100 CPU @ 3.70GHz

- RAM: 8 GB - Single DDR4 2666 MT/s (PC4-21300) SR x8 DIMM 288-Pin Memory

- Drive: SSD -- 128 GB -- ADATA SU800 M.2 2280 128GB Ultimate 3D NAND

- Power supply: EVGA SuperNOVA 1000 G3, 80 Plus Gold 1000W

I was using the open-source ethminer to mine ETH for a couple years or so. Through the following command line:

Code:

ethminer.exe -P stratum://0xmy_eth_id.my_mining_rig:x@us2.ethermine.org:14444

So a few days back I got a notification from the mining pool that it hasn't received any good hashes. I checked my mining rig, rebooted it, and it was showing the following errors upon the start of the ethminer:

I did some search and found out that people were suggesting to increase the size of virtual memory. So I did that as well, raised it to 50GB:

rebooted, but the miner was still showing the same error.

Any idea what is going on there?
