Lots of pools to choose from. Getting 1591 etn 270 Kh/s. (at fairhash)
I'm overclocked to 475hz. Temps near 54/53 C.
Gotta keep it going until Fork time.
Overclocking is tempting but I'm too afraid I might mess something up or hurt the longevity of the machine if i want to host it in a facility long term.
That's totally valid, but considering the length of Bitmain's warranties and the speed in drop in profitability of the past couple miners they've sold (D3, A3), there's not a huge risk if you're careful. Not promoting or even necessarily condoning overclocking, but I do it. I have my L3+ overclocked for 6 months with no problems, the A3 for the two months it was worth bothering running it, and have my X3 overclocked as well. Just make sure your temps are good and your HW errors are low if you try it.
Think of it this way: if profitability the first 2 months is 5-6x that of later (using the A3 as an example), overclocking for a 30% bump is totally worth the risk if you can get those results for that whole period, even if it dies say 4 months in. Using the S9 as an example, it would probably have been very profitable to overclock it on arrival, but that machine was profitable for a very long time, so if it did kill it within 3-4 months, you might have ended up losing money. It's all about the risk/reward.
Also killing your machine limits resale to parts only, but I don't think that's as huge a loss with the current era of ASICs.
