I rarely will see a 470/480/570/580 advertised on NewEgg for under $300 and (momentarily) in-stock - I keep getting tempted to buy as many as I can and put them up on craigslist for $100-$200 more....

 *looks around for a second wondering how I got transported to Poloniex Trollbox*

 Lowering TDP will drop hashrate after a while - but initially it tends to be a much lower hashrate drop than a power consumption drop, which matters if you have expensive electric and need to maximise EFFICIENCY.
 Lower TDP also keeps a card cooler, which in some cases CAN improve hashrate via the card not going into thermal limiting.


 There is no "one true answer" though, as there are many variables that affect each person differently.

 Keep in mind that a lot of major farms pay less than 3c/kwh for electric - back in the Darkcoin days even with 8c I was break-even at WORST (but summer rate at 14 convinced me to move to something else, and I never looked back).

 No need for hypothetical FPGA-based X11 miners to explain why it got unprofitable for many small miners.




 I doubt that ETH going to PoS will affect it's price as such - it WILL kill the ability of miners to mine it once it goes 100% PoS, but miner profitability does NOT drive price - price drives profitability.

For the most options, try CoolBits 31 - 32 sets a single bit that isn't USED by anything AFAIK, 31 sets ALL the bits below that one.

 sols is a ZEC term - and that looks more like a ZEC hashrate than a Skein one (my 1070s were doing over 500 Mhash/sec on skein when I was checking it out and testing).

 430 would be a tossup on ZEC with a 1070, though you seem to be using somewhat more power (as to be expected from a Maxwell generation card).

 Alex78 for skein (I think that's a ccminer branch).
 Not sure on groetsl, tried a few varients but they all seemed to work the same.



 ANY SHA256 miner should work on a DGB-SHA256 pool that can handle the S9.

 And quite a few individual leaders, or very high placings, on the various projects.

 Speaking of which, has anyone seen a list of projects that is sorted by FP64/FP32/Integer GPU usage?

 I know Milkyway is FP64, and Moo Wrapper is integer, but no clue on the other ones and that info seems to be a bit of a pain to find for more than one project at a time.

 Whattomine doesn't list all algos on the compare page, so yes it DOES matter.

 9-)

 For one example, Skein isn't there (even though at least one Skein-based coin is TON more profitable than Pascal which IS there).

 Additionally, the "hashrate" shown on many algos on many cards is WAY off.


 There are already quite a few coins that NVidia cards mine for higher profitability than AMD cards do - even ZEC in the last month or so has been seeing NVidia achieve equal-to-better hash/$ vs AMD, and ZEC isn't exactly small based on the number of cards needed to achieve the current network hash (I think ETH is the only "bigger" GPU-mineable coin on that basis).


 I doubt that profitability of all coins will return to where they were at a year ago - but I DO expect to see a shakeout and a major dump on profitability for most GPU-based coins over the next year or two - probably triggered when ETH starts *finally* phasing out POW heavily (ballpark when it moves POW to half or less of total "Proofing").

 The interesting thing is if that does end up being the timing, it most likely happen pretty close to the same timeframe that the next generation of SHA256 (and probably Scrypt and possibly X11/X13/X15/etc) ASIC miners start selling.



 Moore's Law has been taking a noticeable hit over the last decade, as current semi tech runs seriously into quantum-level issues, and Silicon reaches the "end of the road" as a viable semi material. The next decade could see Moore's Law end - and it looks definite that it's going to have a major PAUSE as a minimum after the 7/10nm nodes go into production.

 Because ETC has a much smaller market cap and is somewhat harder to trade?

 Also, ETH isn't going POS real soon - they're planning a "phased-in" multi-stage transition starting around end of the year.


 I don't remember any Scrypt (Litecoin) FPGA miners, seems to have skipped straight from GPU to ASIC.

 X11 (Dash etc) definitely skipped FPGA.

 I do agree that GPU rigs are a lot more flexable - it's the tradeoff for them being less efficient than an ASIC.


 Panda wasn't the first "custom GPU" type rig, more like 3'd I think - they do seem to have become the most popular though due to good marketing and *relatively* reasonable pricing compared to the earlier entries.
 It's too bad they insist on using the "mobile" type boards rather than standard boards, but they can cram those mobile boards in tighter.

 Nope - I find mixed rigs under 7 to be MORE stable than 10 - though not by a lot - and NO more difficult to set up.


 Mining ETH on a 1070 is not a real good choice - ZEC would be a better choice, some of the smaller-cap coins better yet, under current conditions (skein and groetsl based coins like DGB have been VERY nice most of the last couple weeks).

 29 Mh/sec on ETH out of a 1070 is reasonable, but 90 watts would need better-than-average memory to achieve.

 400+ sol/sec on ZEC out of a 1070 is trivial using EBWF miner, and you probably can get there with some tweeking on under 100 watts.

 NOT 4U or even rack mountable.
 Has to be modded to hold more than 3 cards.

 Not even CLOSE to what the OP was asking for.

 Which does NOT stop the "Unable to get mining info from wallet" error messages.
 I've DONE that.

 I'm not sure if that's a bug or if the message comes from something else.

 I haven't figured that one out myself, but I just ignore it as it doesn't seem to affect anything.

 There are other miners that work well for Nvidia.

 As I said, custom "mining specific" cases - using an adapter or modifying the case counts.

The EVGA 1600 should handle any S9 or T9 model
I WOULD recommmend strongly that you make sure the circuit it is plugged into is a 20 amp circuit, and do NOT plug anything else into the other side of the same outlet if the outlet is a common "duplex" type outlet - and I would also recommend that you only plug it into a 20-amp rated outlet if at all possible, as that thing WILL overload a 15 amp outlet if it's running at more than about 90% of max capasity (though a T9 shouldn't push it QUITE that hard).

 220 VAC is actually the normal voltage that is fed to US residences and small businesses, but it's center-tapped AKA "split-phase" so you can pull 110 off of it for most "common" usages in the US.

 Electric Driers, Hot Water Heaters of more than about 6 gallon capacity, Electric Ranges, most wall-type electric heaters, some HIGH capacity A/C units, are normally 220V.

My "new build" that I've got the parts for but haven't had the time to get to (moving is PAINFULL when you get to my age with as much stuff as I have to move) will use a minor varient on Phil's Gigabyte - the D vs the HD

Only differences seem to be "2 PS/2 type connectors" vs 1 + 2 USB, and my board has a D-Sub VGA port Phil's doesn't have.

 I suspect they will work the same.

I'm liking DGB the last couple weeks - on my A2 Scrypt miners.

 Made more with my 1070s and my 1080 doing something else though for the last week and most of the last month - though DGB-skein and DGB-groetsl were good money makers a lot of the month.

I believe the best option for XMR on a hash/watt basis is still the NVidia GTX 750 ti - for some reason they hit a real sweet spot.

 There are some CPUs that can argue the point, though, but for some reason I don't think they've been beat (though they HAVE been challenged) on a hash/watt basis by newer GPUs.


 250 hash (common with a very mild overclock) on something like 45-50 watts actual usage (don't go by TDP, go by at-the-wall measurements)....
