Well it is all about temperatures. I went from 384M to 387M -- noticed no temperature increase and my hash rate increased by about 4Mh/s on average.
I have really cold AC on the unit -- Output temperatures are no hotter than 59 degrees C on "Temp(Chip)."
Didn't notice an increase in HW errors -- although Chain #3 (5 HW) and #4 (22 HW) have always shown some over a 24 hour period. Another person had similar findings in another post.
The unit is quite impressive and the fan can get pretty quiet if the airflow and temperature is right.
I "rent" it on Nicehash when the price is at a certain level -- otherwise it defaults to a select alt coin pool where I mine a variety of alt coins. lol
Nicehash is the best option if you want to get paid in btc... What pool are you using to mine the alt coins and what PSU are you using for L3+?
I've done well with ProHashing as the primary and litecoinpool as the secondary. ProHashing lets you choose to be paid in any coin. I choose Bitcoin.
Be warned that ProHashing has some stability problems (for example the server, including mining, was down this evening due to a storm, so they say). But even with wiggly uptime they still consistently beat Litecoin profitability by a significant margin (even with the 8% bonus that litecoinpool offers).
I've seen an average of about $54 a day for a single L3+ for the last week. Of course it's been kind of an insane time for cryptos recently. Looks like we're in a correction now.
If you want rock solid stability, then go with litecoinpool. It's amazingly reliable.
