How many ways do we have to say "Not only no, but HELL NO"?

 The +12V output is NOT rated for 2800 watts, it's rated for 1335 watts MAX and THAT IS ALL YOU CAN PULL OUT OF IT ON +12V.

 Plot on a local hard drive, make sure the plot is optimised, then copy that plot to your NAS drive.
 Repeat as needed.

 Same concept is needed, but a lot MORE so, for those that do BURST mining via cloud storage.

 All of my BURST mining is done on local HDs on machines that are also GPU mining other stuff, though - for me it's more of a "well, I got all that empty space on the drive, might as well get SOMETHING out of it" thing.

 In case you haven't noticed, Bitcoin has dropped over 25% from 2 weeks ago, most other Altcoins have dropped by half OR MORE from where they were at 2 weeks ago (Litecoin is the only LARGE CAP exception, having only dropped about 20%) - it's NOT just BURST price dropping.


 I suspect the "big increase in miners" on your pool isn't actually that much of an increase as it is folks having shifted pools, a LOT of folks specifically including most of the long-time BIG miners seem to have moved off pool.burstcoin.biz the last couple of days - used to have a few hundred mining there as of early this morning it was a LOW single-digit number and as of a few minutes ago had only recovered to perhaps 20.

 More like 30% AS A MINUMUM and more commonly 50-150% on RX 470/480/570/580 - when they have any for sale at all.

 I do wonder how much the MANUFACTURERS have jacked prices up - I doubt it's ALL on the retailers.

 AMD is also looking at what happened after the Litecoin/DASH craze collapsed - and trying to AVOID a year or two of very poor sales due to there being way too many ex-mining GPUs on the market dragging new sales down a ton.

Durability is more about the temperature the chips run at than the watts going through them - with good water cooling, *IF* the RAM and the power regulators are included on the waterblock, pushing the cards to 110-120% should not drop durability noticeably IF AT ALL then running them at 80% on stock cooling.

 In well over 20 years of experience with LINUX, I have found it to be MUCH more stable on good working hardware than Windows.

 Pushing overclocks excessively, not providing enough power to handle the spikes that ALWAYS happen in GPU mining, and not keeping the cards cool enough can cause stability issues on ANY OS though.

Windows makes it easy to mix-and-match different GPUs - at a cost in stability.

I've seen that picture before, attached to a scam site.

Been a few months though, I don't remember the name of the alleged maker offhand.

 Not once Segwit/LN gets adopted by LTC.

 If you want a trollcoin, look at DOGE.


 LTC has NOT been the consistant most profitable Scrypt coin for the last 2 months - DGB was quite a bit higher for a while, GAME has also been higher at times, JUST among Scrypt-based coins.

 Long term, I do see a major shakeout happening in Crypto - there really isn't room for dozens of coins to be worth much, though I can see a possibility of perhaps a half dozen surviving long-term.

Any Scrypt ASIC is capable of mining ANY Scrypt coin, all you have to do is point it at a pool for that other coin (or if you solo mine, point it at the correct wallet).

 If you're mining ETH on a 1080ti you're stupid - and making a LOT less than the card is capable of if you mine stuff it's EFFICIENT at.
 There are quite a few algos that a 1080ti manages twice OR MORE the hashrate of a RX series card - the algo ZEC uses is the best known, but the 1080 ti also is very very good at groetsl, skein, lbry, lyra2rev2, just for the algos I've personally tried mine on and can compare with my RX 470s.

 Also, finding RX 470/570/480/580 at under $400 the last 2 months has been a rare thing, even if you manage to sneak in on a Newegg restock it's "limit 1 per 48 hours" WHEN they have them and more like $250 - and other retailers have the same sort of limit when they have any at all.

 They're also NOT making $2.30 a day any more, even if you BIOS flash them and overclock them enough to nearly match the hashrate of my R9 290 cards - as of RIGHT NOW they're grossing a hair less than $2 (though probably netting a hair more than my R9 290s due to much lower electric use) even if they CAN get to the 29 Mhash/s my R9 290s manage.

 That 1080 ti also will retain it's resale value after the crash - the RX series cards will probably be selling for a LOT less than MSRP 'cause of oversupply.


 I'm not saying the RX cards are bad - I'm just saying that for the last 2-3 months calling them a "$200 card" has been generally a LIE - and will remain a lie for most folks 'till the current gouge pricing goes away.
 You also have to factor in that the total SYSTEM cost is going to be a good bit higher per card, as you need more RX series cards to match the income of GTX 1080ti cards therefore you need more rigs (and more MB/CPU/RAM/HD/PS etc).

 4 months ago, the RX were a very very good and often the best mining option - but at recent gouge pricing it's a lot more of a question mark - and when ETH moves to PoS it's going to kill the biggest coin that the RX series EVER had a major advantage on.

 The 1080ti isn't 2x a 1070 on anything that I am aware of.
 The 1080 ti will generally use a little less power for 2 of them at slightly higher hashrate vs 3 1070 cards when doing the SAME algo even at the SYSTEM level.

 You just answered the primary question you should be asking - trying to be profitable mining with a high electric rate is generally NOT possible for the long term, though there has been a short-term ability to do so the last 3-4 months or so due to a massive price rise on most coins coupled with production limitations making for shortages of available mining GEAR not letting the network hashrate rise anywhere near as fast - but the last couple weeks of price DROP on coins coupled with accumulation of mining gear has led to a significant drop in profitability and a high probability of "high cost electric" producers never seeing payback on anything they invest into new mining gear at this point.


 Short form - if you don't have cheap electric, you probably WON'T make enough of a profit to pay for your gear.

I don't use the Curecoin wallet in Windows.
For that matter, I don't use the Curecoin wallet at all.

I also don't use Unity/Trinity/whatever the Ubuntu "default" windows manager is called (the one they announced a while ago that they were moving AWAY from), as I found that XFCE is a much more useable window manager with a TON less overhead and performance issues.

I just find it totally WIERD that a program would use what appeared to be a "SYSTEM" menu to access a PROGRAM setting - in ANY OS.

 Apparently it's just wierd positioning in the pop-up menu that pops the menu up RIGHT UNDER the "system" settings menu.
I've seen stuff pop up outside of the original menu before (FAH does something similar on it's config menu, but that window is usually bigger than the original so hard to avoid) just not in such a confusing spot.

 I also find the default UBuntu insistance on putting the menu bar at the TOP of the screen irritating - I never leave it there on my own machines - and have never understood why they do that.
 I do concede that is probably a personal preference / what I'm used to from EVERY OTHER OS and LINUX distro I've used sort of thing.

 Afterburner definitely blows away the available LINUX tools for overclock and fan management - but LINUX is a ton more stable than Windows.
 I've yet to have a windows-based mining machine go A month (more commonly a couple weeks or less) without a hang or a reboot, my LINUX machines routinely go for months if I don't lose power or have to move them.

 I don't DO remote management so can't speak to either side of the question there.

 The board is available WHERE?
 In what quantity?
 Used, or refurb, or VERY LIMITED left over new stock from when they WERE still being made?

 I have seen a LOT of links to that board for sale - only to turn up with "out of stock" notices when I got curious and checked them, or other folks check them and state "out of stock now".
 It seems to be a good board for riser rigs *WHEN* you can get them, but it's not a good board to recommend when it hasn't been MADE for years, unless you're also going to recommend alternatives that ARE current production and have been more reliably available over the past year.

 ASRock has put out some more recent "mining" targeted boards, but I don't pay much attention to them as I don't build riser rigs and couldn't care less how many PCI-E 1x slots a board has.

-50 volts at 28 amps is 1400 watts, or almost half the TOTAL rated power output of that power supply.

 That's NOT a standard computer power supply - like NotFuzzyWarm I'm inclined to believe it was intended for use in landline telecom equipment.

Bah Humbug, if it wasn't for grcpool I'd be #1 on Moo Wrapper.

 8-Þ

Unless you have cheap electric, though, the S7 is not going to show much profit and you have a VERY high risk of never getting your money back out of it.

 Even with the mods Sidehack came up for it, it's about half or a hair LESS of the efficiency level of the S9 or R4, and a little better than half the efficiency of a T9 or Avalon 721/741.

3 phase 240 volt exists - but is bloody RARE, at least in the US.

 3 phase in the US *normally* starts at 480 volts, can be Wye OR Delta depending on the power company and what you ask for but IME is *usually* Wye.

Trying to split it down to 220 without a transformer comes under the "VERY VERY BAD IDEA" concept as it's not DESIGNED as split-phase like normal 220 service is.



 460 amp 3-phase supply should give you a TON of "capacity to grow into" - if you can get enough airflow through the place to manage the heat generation.
