I'm still trying to decide whether or not I should sell my S9's and the 1 L3+ that I have. It's getting too hot to mine here this summer and I'm not sure if I should hold out for the market to return or not.. any advice on what you guys are doing?
You can always flash the fixed freq firmware, 550M for example, and then tweak the frequency from there to reach a desired temperature. You could also set the fans to 100% manually to keep the miners a bit cooler, although that is more power draw.

Ignore scammers on Skype, Telegram, etc. I will only ever contact you via forum PMs. See profile for fingerprint.

Good decision. More and more people should do this. Better for the coin.

Only reason my 3 are still hashing is that I finally got my solar turned on 2 weeks ago.

I was actually curious if this was a good buy in btc terms (obviously it was great in $$ terms).
I was able to find one of the first buys from phil:
https://bitcointalk.org/index.php?topic=1493601.msg15031192#msg15031192

he paid roughly 4btc.
so, you got (if 100% uptime, which is questionable for batch 1, but possible) 1.839 btc extra, but used electricity for 2 years.
If your electricity cost is $0.1/kwh, then you used about 0.1X24X730=$1752
So, in btc terms at current prices, you spent about 0.3 btc on electricity if you did not use lower (or higher) priced btc to pay for electricity.
1.839-0.3=1.539 btc profit on 4btc investment or about 19%/year return in btc terms. Not bad, indeed.

I bought batch 3 and later batches, which made it worse as far as btc return is concerned. Plus, a couple of first batches lost 1 board Ea, which I had to replace. Overall, apart from participation in the network, which might be the most important part, it was pretty much useless.

or they do what they did every past: sell the slower ones first and then when those are sold out, magically re-appear with the 14TH batches.. Smiley

tech q: does anyone know what the quality of the bitmain psu's is?
power factor, thd etc.?

im wondering as it doesnt hurt much when you have one or 2, but many can cause serious problems when its not that great; high currents in neutral line, high 3rd and 5th harmonics etcetera?

has anyone expirience with the awful whining noise of the S9i miners?

i have some as an upgrade, but at a certain point they generate a sound that goes through the bones!
I had one connected to silencing hose at inlet and outlet, but the noise that came from the machine itself was horrible and pain to the ears... When the fans speeded up and or down a bit, it was as good as gone...
bad thing is that it seems to be right at operating speed.

anyone experience this as well?

Yes some of them do this, its infuriating! A well located bit of duct tape near one of the fan blades tends to eliminate the odd harmonic

also is anyone facing issues with bitmain PSUs? many I have are getting brown... and black after. miners seems to be sucking the normal power. I suspect the PSUs are not good. Gables at the connectors are getting very hot to the point that I can't touch them and it is damaging the plastic and isolation.

Hello. The S9 began to disconnect from the pool after 1-2 hours of operation. The S9 itself works. What can be wrong?

Have you tried connecting to other pools to see if you get similar issues?

After that try a different router (often home broadband routers block mining), or connecting via a different network to see if you still have the same issue.
