I got these risers that provides a 6 Pin to SATA adapter cable for power. I've been using the risers with the provided cables for over a month now without any perceivable issues (no overheating, etc). I am powering 2 risers per PSU SATA since I don't have enough ports to power 1 riser per SATA.

The thing that got me worried is that recently I've been reading a lot of comments saying that 6 Pin to SATA are bad, like really bad. Most people were recommending 6 Pin to 6 Pin power adapters for my riser, so I searched for 6 Pin to dual 6 Pin on the retailers available to me but didn't find any, only 6 Pin to dual 6+2 Pin which are marketed to power GPUs. Is it a good idea to power risers with those cables (since the 2 pin from 6+2 pin would be left hanging)? Would it be any safer compared to my current configuration?

[stale shares]

Recently I've been searching for ways to improve my mining efficiency, with stale shares as the main concern since they are a bit on the higher end (~3%). The second one being system stability, Windows 10 feels a little too wonky sometimes.
Mining setup:

OS:	Pool:	Software:
Windows 10	Ethermine	T-Rex 0.19.11
________________	________________	________________

For stale shares, with a quick Google search I figured I should focus primarily on pool latency, with that in mind I found this really cool software called "Sonar" which helps you find the closest pool to you. According to Sonar, the nearest pool to me (Brazil) should be Binance pool (~35ms) instead of Ethermine (~210ms). Every other pool besides Binance pool starts from at least 190ms, which makes sense since apparently Binance is the only pool with servers in South America.

My main concern about switching to Binance pool is that they only own 0.91% of the network hashrate as of right now, althought not sure if that matters considering they pay on a FPPS basis. That aside, looks like a sweet deal to mine directly onto the exchange I use to cash out — according to u/OldWillingness7 over Reddit:

If you mine in ethermine or flexpool to your own wallet, and then you want to cash out, you pay tx twice.

Mine to pool > payout to your wallet (tx1) > move to exchange (tx2) > sell it, or trade, or whatever.

You can mine directly to your account on an exchange, like binance or others. Downside is they control your private key.

Pool > exchange (tx1) > sell.

No tx fee if you mine and trade on Binance.

As for system stability, I'm considering switching my farm to HiveOS which looks like the best one out there. Hopefully the mining rigs stops freezing as often as they do on Windows 10. Since I'm doing that, might as well try mining on the Hiveon pool for a few days and see if their non-existent fees could outweight its higher latency (about ~200ms) compared to Binance pool.

What are your thoughts about this? Is there anything different I should try instead? Any help will be greatly appreciated!

[Mining Rig:]

Mining Rig:

• PSU: Corsair RM1000i (1000W)
• Mobo: B450 Tomahawk MAX
• Processor: Athlon 3000G
• Storage: A400 240GB SSD
• GPUs:
  4 × Strix 3070@123W
  Core Clock +0
  Mem Clock +1200
  1 × Strix 3060 Ti@125W
  Core Clock -502
  Mem Clock +1200
• Other: 5 SATA powered risers
• RAM: 2 × 8GB
• OS: Windows 10 20H2 (latest)
• Mining Software: T-Rex 0.19.11

When it happens, the GPU fans continue spinning but not generating as much heat as when they are mining. The RGBs are also still present although nothing is responsive (i.e. mouse/keyboard are unable to wake up visual output).

I want to disconnect this rig from my monitor and let it run by itself - but it keeps freezing and I don't know what to do. Any help would be greatly appreciated.
