Hey all,

I've been reading this forum for a few months, and have been waiting to get into the mining game for a while. I understand there's a lot of uncertainty around Sia and the A3 with respect to long-term profitability, but even at $30-ish daily payout the ROI is far superior to other miners and the payback period is the shortest in the market (so far).

I finally got my A3 set up tonight, and things are looking great - but I have a few questions.

First, current stats:

PSU: EVGA SuperNOVA 1600 G2, on a 110/120v, 20amp dedicated circuit

Avg hashrate: 830GH/s

Frequency: default 600

Temps:
PCB   Chip
45   58
45   59
46   60



Fan speeds: ~3,400
(I'm getting such low temps because it's sitting with the intake pointed at an open window with ~20F outside temps, so that won't last too long but really enjoying that it's quiet enough to sleep next to. I like a little white noise anyway)

Now my questions...

• Mining pool selection - I set up SiaMining at first and was getting around 80SC/hour. In the spirit of decentralizing and supporting good pools, I swapped over to Luxor, and my SC/hour was much smaller. After over 90 minutes it was estimating about 30SC, so I reverted back to SiaMining. However, I just refreshed the Luxor page and it is showing 362SC for just under 2 hour's work. Why does the number fluctuate so much, and why was that figure so delayed? Is that typical with Luxor, or is it due to the nature of PPLNS? Also, it seemed to take MUCH longer for my hashrate to reach ~800 on Luxor (30 mins or so) vs. SiaMining where I had full hash within a couple minutes. Or should I go with F2Pool instead? Haven't tried that one out yet.
• HW error rate - People have been mentioning HW errors as "a lot of errors" or "an acceptable rate", but I haven't seen hard stats on what those rates actually are.
   Is 0.01% too high? 0.1%? 1%? I'm currently at 0.006%...
• Overclocking - Given my stats above, I'm surprised everyone is having to underclock their miners... I guess I'll chalk it up to it being reallly cold outside at the moment. However, I'm looking to overclock my miner, at least during the day when I'm gone and don't need lower fan speeds for noise. I'm not going to touch anything until my Kill A Watt shows up and I can monitor power draw, but with the EVGA SuperNOVA 1600 Gold on a 110/120v, 20Amp dedicated circuit, what does everyone think I should limit my at-the-wall wattage to? Also I'm more than happy to get a read on draw at a multitude of frequencies since seems other people have also asked for that as well. Curious about HW rate tolerance as well.

Thanks in advance!
