MUCH higher base settings on core clock, and if that's the one with 2 x PCI-E power connectors it's got probably THE highest TDP setting of any GTX 1070 model at 230 watts.

 410 sol/s is quite reasonable for a card that has a FE-level 151 watt TDP  and base/boost clocks.

 Stock memory clocks on 1070 models don't seem to vary much - most are 8000 Mhz or very very close to that.

 I haven't done a lot of testing, but I noticed a significant difference between my 2-fan Gigabyte models (180 watt TDP) vs my EVGA SC models (151 watt TDP) and my Gigabyte "ITX" models (also 151 watt TDP) - the EVGA and "ITX" were pretty close, the other Gigabyte were 20 or so sol/s higher at stock settings.

ETH profitability, even with todays price crash/correction and the huge surge in network hashrate over the last 2 months, is still a lot higher than it was 3 months ago.

 On the other hand, the drop *MIGHT* convince some folks to back off on further "massive farm expansion" - depends on how many of the bigger farms are in super-cheap power areas that can probably weather the long-term drop long enough to achieve ROI.


 Also depends on if the past week is more of a "correction" (which is what I strongly suspect given fundimental factors behind ETH in particular, among SOME of the other coins affected) or the start of a collapse.

Scrypt has been dominated by ASIC-based miners for YEARS now.
SHA256 (Bitcoin etc) has been ASIC dominated even longer.
X11/X13/X15/Qubit (and 1 or 2 others, I forget the entire Baikal list) have been ASIC dominated for about a year now.

 If an ASIC exists for a coin, don't bother TRYING to mine it on any GPU.


 I didn't realise Whattomine had added an option for the 1080.
 You do need to fix that URL link though, you forgot a " . "

 9-)

 Wattman is a sad pathetic joke compared to Afterburner - that blurb about "groundbreaking" is a flat out LIE, Wattman is LESS capable than Afterburner was YEARS ago.

 Try setting a fan CURVE on Wattman, for one major issue with it. Capability doesn't EXIST.

 
 

I have mined ZEC directly to Bittrex for large parts of many months now.

 Poloniex also worked, but Poloniex has SO MANY MAJOR ISSUES I recommend avoiding them entirely.

 Equipment cost and electric cost have ZERO effect on market cap, and have no direct input into price at all.

 Price effects the profitability of mining, NOT the other way around.

 The same number of coins are generated no matter how many - or how few - miners are competing for the block rewards and block fees - and number of coins generated is what affects price, NOT how difficult it is to mine those coins.


 Market cap is STRICTLY the product of the number of coins in existence times the price per coin.

11 U is a very odd size.
 You could use 1x 3u case and 2x 4u but the cooling in the 3u case won't be as good.

 Also, as a general rule "datacenter" hosting is NOT designed to handle the density of cryptocoin mining rigs on a heat or electric usage basis.

Given CURRENT pricing on RX-series cards, the prices unfortunately DO make sense.

 But try FINDING a 470/570 at $200 for the last month.
 I also disagree with the "just about any algorithm" part of that statement, though they WERE competitive to superior on the algos used in most or all of the LARGE MARKET CAP coins on both a hahs/$ and a hash/watt basis *IF YOU MODDED THE BIOS*, and fairly close even on non-modded cards.

 I do suspect they'll sell the things without a problem for a while - just based on there not being enough cards to go around at all - but once the "crash" happens, they're going to have to price them quite a bit less than the consumer version to get any sales at all due to the very very low resale value.

 If you compare vs MSRP, AMD cards are pretty close to NVidia on hash/$ for ZEC - and they're a tossup on hash/watt at any price.
 They just don't ramp quite as high - yet - since AMD hasn't released new-gen "enthusiast" level cards yet, just mainstream ones.



 Risk is growing pretty fast, with prices dropping on most or all of the "big cap" coins AND total hashrate still growing fast, while reward has dropped quite a bit just in the last week.
 It's starting to look a bit iffy again on "will one achieve ROI if I build a new rig TODAY" for a lot of options - though if your electric cost is low, you should still manage ROI at some point.

 If profitability drops back to where it was 6 months ago, I personally will be fine - I was plenty profitable THEN - but it would drive quite a few folks out of the mining business like the last "bust" did, at least for a while.

 On the other hand, we might see another "price jump" stage too - no way to know for sure.

 1. Again, that's "investment" not "mining".
 Litecoin at it's low right before the halfing was around $2 for a while - I forget offhand if it dipped under $2 but I think it did at least once.

 2. That's a reasonable point.

 3. Don't invest more than you can afford to lose.

Anything Intel built a few years ago would NOT be competative in the current market.

 The BitFury *chip* was demoed to be capable of being more efficient than the BitMain *chip* - but at a very low hashrate.
 I suspect BitFury has been selling them to large farms as opposed to using the things themselves, or they are using them but have limits on how many they CAN use due to power limits at their farm(s).

 Only because the 1070 has gotten into "shortage gouge pricing" situation, and the very recent small price rise on the 1080.

 Prior to that, it was pretty much a tossup between the 1070, 1080, and 1080 ti on hash/$ - a hair over 1 sol/s per $ on any of them.



 Relative profitability between ZEC and ETH varies a bit - it's usually close, but commonly ZEC is slightly better over the last couple months.

 Polo routinely disables wallets for a week at a time for "maintainance" - that's NOT just an ETH thing, that's a Polo thing and it's one of the MANY reasons I don't use Polo any more.


 There's a LOT more than "a few thousand" GPUs mining ZEC, my ballpark estimate came up a little over a million - but most of the smaller-market-cap coins might only have several thousand or a few tens of thousands of GPUs working them.
 ETH has something in excess of 2 million GPUs working it by my same ballpark estimate.
 When THOSE move, it's going to be a noticeable hammer on the profitability pretty much all other GPU-mineable coins - even the NVidia ones as it's now obvious that a lot of NVidia 1070 and 1060 rigs are getting built by ETH mining farms due to the lack of high-end RX cards to buy, and some Nvidia-using ZEC miners will move out of ZEC when it's profitability gets hammered by the AMD influx.

 That's the primary reason I don't talk about what I'm mining at this time - I've got 18 GPUs pointed at it right now, and I'm doing about 2% of the coin earning.
 It would take a MAJOR profitability hit if 1000 modern GPUs suddenly switched to it.

 That is flat out NOT TRUE.

 Litecoin was DROPPING and continued to drop when ASIC were first introduced for it in 2014.

 DASH (X11) was flat and stayed flat for almost a year after the first ASIC was introduced for it last year.

 Bitcoin might have gone up but it was ALREADY climbing by the time the first ASIC showed up for it.

 What ASIC is indicative of is that someone believes there will be enough demand for an ASIC to make it profitable enough to make one - yet quite a few ASIC makers have ended up going bankrupt (KNC and Butterfly Labs are probably the best-known examples of ASIC miner makers that actually delivered product ending up bankrupt, but it's fairly long list that includes the majority of Bitcoin ASIC makers that ever managed to deliver product).

 In fairness, MOST of the ones that went bankrupt did so as the result of overoptimistic promises on "delivery timeframe", though in KNC's case it was *also* at least in part how unreliable their miners proved to be overall due to bad design decisions and poor chip design work.

 Not at CURRENT pricing on the RX 470 - when you can find them at all - and only ever was true for ETH/ETC/derivatives and possibly a very few "small-market-cap" coins if you limit the list to NEW cards.
 (My R9 290s cost me $180 from Newegg in a timeframe that the lowest-cost RX 470 there was the SAME price, but outhash pretty much all RX 480s much less RX 470s).

 Prior to the current "AMD shortage price gouge" the 470 *could* at least argue that point - though a lot of low-cost 480 and 580 cards could argue the point due to higher hashrate and not much higher price.


 What's odd is that they have this card and the 106 Nvidia varient listed on their "main" website - but they direct US customers by default to www.asus.com/us/ by default (and I have not found a workaround for the main web page to date, just for "further in" ones) which does NOT list these cards at all.

 The odder part is that it's 470 based instead of 570 based - I wonder if that's why some rumors are talking about "limited run", the GPU chips might be comming from previously rejected chips that were fine EXCEPT for the video-specific part of the chip?

I'd switch the R9 380x over to ZEC - they should be more profitable there as they're not real good ETH miners.

For ZEC and it's offshoots, sol/s IS for all practical purposed the same as hash/s - completed "units of work / sec".


 For most AMD RX series cards, ETH is generally the same to a little more profitable than ZEC.
 Older AMD cards vary.
 For NVidia cards, the 1070 and 1060 are the only ones even worth considering mining ETH with but are almost always more profitable on ZEC or some of the small-cap "skein" "groetsl" "lbry" and such coins.


 For mining, 9 cents/kwh is NOT cheap. There are way too many major farms that pay 3c/kwh or less and even some of us SMALL miners in the right areas can get to 3 or a hair under.

solving captchas is NOT mining.

 The "proof of capacity" coins like BURST and STORJ and MAID might be what you are looking for.

Innosilicon seems to have stock of the A4.
Try some of the smaller makers perhaps like EBit?

check whattomine on the various skein coins, and the master compare page on groetsl.

Possibly lbry or the varients.

There IS no one true answer at it varies from day to day and sometime hour to hour.
