At which point the SDK is installed.


 You're trying to make it complicated, in this case it's actually VERY simple.


 *NOT* like installing the fglrx DRIVERS can be a PITA and a bit complicated, with all the dependencies and such....

 1100/1500 works best on my R9 280x - Gigabyte Windforce 3GB models.

 higher memory clock = quickly SLOWER mining, higher core doesn't give any better hashrate, lower clocks are a slower taperoff on hashrate.

 Other cards may vary, especially other models or other manufacturer cards.

I spent about 8 years working the computer show / hamfest circuit for a living - based out of the Indianapolis area, but made a lot of shows in Ohio - though I only went to the Hamvention twice, way too costly for a small seller like I was.
 Finley on the other hand was nice.....

*ROFLMAO*

 Takes a LOT longer to design an ASIC - and Ethereum will go PoS before any ASIC for it can reach ROI.

 I seriously doubt that ANYONE would be dumb enough to waste the $MILLION(s) to design an Ethereum ASIC - and the bloody thing would be pretty expensive given the RAM requirement to mine Ethereum at all.

 Only reason I'm not pushing my megas to 110 across the board (they're all CAPABLE of 109-111 range at the 1200Mhz setting) is that I don't trust the "stock" power supply in 1 of them. 2 already got X1250 transplants (one had a PS die on me, the other I couldn't figure out WHAT it was rated at). The 4'th one had a 1300 Gold in it already when I bought it from Zoomhash - apparently it ALREADY had it's stock power supply death before it got to me. 8-)

I don't know why people keep talking about an "Innosilicon data hall" or "farm" - there is ZERO evidence I have seen that they mine with the gear themselves, other than during testing.

 I suspect some of their DEALERS do so (and I am 100% certain that Zoomhash does - they've mentioned THEIR farm and hosting center), but that's not INNOSILICON doing so.


 Bulk sale of chips would be nothing new for them, reference the A1 and the LKetc "Dragon" designs.....



 As far as companies like KNC failing to deliver units on time - it's called "breach of contract" when they SPECIFY a delivery date and fail to meet it by months or in some cases YEARS - and IS in fact legally actionable as such.
 I do agree that such actions are probably not covered by most "consumer protection" laws nor are meant to be, but that doesn't mean the pre-buyers and buyers have ZERO legal grounds to sue and recover damages. Buyers are pretty much limited to recovery of any money they spent on such pre-orders and purchases that never got filled, and arguably have grounds for partial refunds for excessively late filling of orders.
 "Lost income" and other such recovery causes over the actual money PAID usually requires ACTIVE INTENT to defraud on the part of the seller, which is a much higher legal bar to clear.

1080 seems to be vary scarce right now - give it a couple weeks to a month, supplies should get more available and price come down to less than list.

 And yeah, it's NOT a good choice for Ethereum even at list, even with the energy efficiency it should have - apparently the drivers for it are a long way from compute optimised, so it's a very low hashrate miner.

 I'm STILL waiting on someone to post Folding PPD on them though.....

 Innosilicon - which might just put the remaining Titans out to pasture in a few months, but I'm guessing the A4's will take more like a year to get deployed enough to render the remaining operational Titans unprofitable (for most).



 There are rip-offs in every country, just happens that for Bitcoin one of the bigger ones was based out of Sweden. It's like saying all Yugoslavians were ripoffs and pathetic as manufacturers just because the Yugo was a piece of junk....

 (Hint - there HAVE been worse and junkier cars than the Yugo - look up the Crosley for an example).

 Actually, I do - I have no family where I'm at NOW, and very few friends.
 Won't be "for a few months" either - I'm NOT limiting my plans to Ethereum - in fact I'm still earning more from LiteCoin right now than Ethereum (already have the hardware, no point in shutting it down since it's profitable even though I can't switch it).

 It's not practical to live on less than $500/month ALL UP in most of the US for most folks, but $1000 is easy - I've not made $12000 in a year in over a decade, but I've been pretty comfortable that whole time. Being single, no dependents, etc helps noticeably.


 DO keep in mind that SOME parts of the US have low rental costs, it's not ALL about insane pricing in places like Manhattan (NY) or Orange County (CA) and such.


 P.S. - I've not "lived with mommie" in 37 years and change.

 A GOOD fan and a GOOD heatsink setup, it certainly IS possible.
 A dual-fan push-pull design does NOT increase airflow much, unless the flow path is VERY restrictive.

Wind energy does NOT tend to be cheap, even with federal subsidies it's BARELY competative with coal even in good wind areas like some parts of Texas, Northern Iowa (Alliant has a piece of a couple wind farms and overpays for some of the output of a couple others), parts of California, etc.

 Says a lot that what was once one of the bigger wind-power manufacturers in the world (Clipper Windpower) here in Iowa is about dead.

 You can get into Ethereum pretty cheap, if you have at least one system with an open PCI-E slot and can dig up a fairly cheap used vidcard.

 The system I put together with the used 7870 I bought cost $80 for the card, already HAD the entire rest of the system parts around doing other stuff at the time, and it hashes about 10MH/s which currently equates to a bit over $1/day.

If you're talking NEW system builds with NEW parts, you should be able to get into the 50-60 MH range fairly easy for a grand, and possibly a bit more if you shop VERY VERY carefully and optimise hash/$ very well.

 2 in one system by themselves.
 84W on the one running the desktop, 78W on the other one, per nvidia-smi - I do remember seeing a little variation, couple watts or so each way.
 Looks like the 970 is more efficient.

 Third one is in a system with my pair of 960s, but I don't have individual measurements on those as it's a Win7 box.
 The really SAD part is that the 960s are only good for about 11MH - they don't scale vs the 950 at ALL, lot more cores and they clock 2-3 percent highr and RUN cooler, but dang they should be a lot faster hashing.

 I also have a 750ti running in a low-profile system now, it's pulling 18 watts for 3.5ish MH (bounces between 3.1 and 3.6 but mostly 3.6) - now THAT is efficient, but the $/hash is pretty sad.

Given that most current or recent ASIC are measured in TERAHASH/s (1000 GH), there really isn't much point to trying to mine Bitcoin on the old Gridseed GC3355 based gear like the Orb. Even if you got them working on BTC you'd be putting a lot more money into the electric to run them for a day than they'd mine in a year (unless you have FREE electric, then it's STILL a ton more profitable to stick with mining Scrypt).


 They CAN be profitable - BARELY - if you have cheap enough electric on Litecoin for now.

To do merge mining, you either have to do it yourself (you CAN run P2Pool but you can't be a member OF a pool), *OR* the pool itself has to do merge mining (I get a large number of DOGE from the Litecoin pool I work with, small bonus not a big help though).

Contradiction in terms.

 

Scrypt discussion should be over there ------> Altcoin mining.


 The biggest miner to date, on the basis of hashpower, remains the Antminer S5+ followed by various S7 batches.

 This is expected to change fairly soon, given at least 3 "experienced" manufacturers having announced "next gen" 14/16nm node mining chips that should allow miners to push at least twice the hashrate of an S5+ for ballpark S7 power usage.

I have a few Ethereum miners running on Semperon64 based systems (I've had these for a decade almost, not going into why I bought a batch of them at one time back then).

 1 Gig ram in most of them (2 in one), Semperon 3000+ (might have one with a 2800+), 30 Gig HD in a couple but most are bigger (ALL of them are running EIDE, they're that old, though they have SATA ports they're very early SATA 1.5Mhz or some such), running Ubuntu 14.04.4 with XFCE replacing that horrid "Unity" junk (basically Xubuntu64 but I never found a site that I could download the actual Xubuntu from OTHER THAN 16.04 THAT BREAKS FGLX COMPATABILITY YOU NEED FOR OPENCL).

 Single PCI-E slot with a mix of leftover cards from Litecoin/X11 mining days and one "used" card bought recently 'cause it was VERY cheap.

 Most of them have old generic PS in the 400-480 watt range, one has a Energmax NAXN 450 (the rest of those I've used all died, I'm amazed this one is still working)



 Basically, you need a 64 bit CPU, at least 1 Gig ram (more is BETTER due to DAG file building), enough of a PS to run your vid card(s), HD or SSD (in theory a FLASH drive will work, but I'd say at LEAST a 16 Gig to have a prayer of running more than a couple days before DAG files overload it, and a 32 would be better).


 I would NOT try to mine Ethereum in a 8 Gig FLASH - you'll run out of space for DAG files in no time flat. 16 Gig isn't noticeably more any more, you can get those from Wallyworld for $10 or less any more.


 The critical parts are a good video card and the rest of the system STABLE. Efficient power supply is a help, since most Gold rated supplies tend to be a lot higher quality than the cheaper stuff.



 BTW - I don't RECOMMEND the Semperons, I just had them on hand and got them working. I'd recommend some sort of dual-core at least (My X240 based systems are a LOT faster at DAG file creation and don't slow the hashrate while DAG creating) and at least 2Gig RAM, preferably 4Gig so you don't have to "split the DAG files" when you're generating them.

Major farms in the US are mostly in Washington, paying ballpark 3c/KWH at most.
I suspect most of the major Chinese farms (all of the ones that have talked publically so far at least) if not all are also in major hydropower areas with VERY VERY cheap electric.

For reference - my GTX 950s are legitimate 10-11 MH miners per card, NOT overclocking them (just letting them boost themselves).

 970s should be more like 40MH if they scaled lineraly with clock x CUDA cores.


 On the other hand, my slightly-damaged 7850 (can't clock it much over 600Mhz or it crashes) is pulling about 8 RIGHT NOW despite the major underclock on the GPU - the MEMORY I can clock up but it doesn't see to help much past stock.


 I'm going with Genoil's comments and theory about it being at least in part limitations in the TLB hardware, it's NOT just the clocks, NOT just the memory, NOT just the cores, it's something deeper.
