Recent experimentation on my Aorus GTX 1080ti came up with the following Afterburner settings for "fairly efficient" mining.

 TDP 75% (188 watts more or less).
 CORE +150
 Memory +100

 resulting in right around 700 sol/s



 I do wish folks would stop just posting "TDP %" figures, as they are MEANINGLESS without the card involved, or what the actual WATT figure ends up at.
 This is PARTICULARLY true for GTX 1070 cards that can range from 151 watt factory TDP (all FE cards, many lower-end cards including the Gigabyte ITX/Zotac Mini/EVGA SC Black/MSI "Aero" ITX) to 240 watt factory TDP (the MSI "Armor" model that has 2 PCI-E power connectors).

 It's ENTIRELY possible for my "80% TDP' figure on that MSI card to be HIGHER than YOUR "100% TDP" figure on many other GTX 1070 cards or even some GTX 1080 models (which start at 180 watts).

 382.33, for those that are Tyop impaired.

 9-)

 Sipolar is USB2 (not an issue of itself) and only .6 amps per port rated (DEFINITELY an issue) - not a good option.

 The ports on the Block Erupter are too close together to be able to use all of them, it would probably handle 28 Moonlanders though (one every OTHER port on each row) but even then cooling might get a bit iffy without a substantial fan blowing lots of air into it.

IMO there is no point to using a high-end Ryzen or high-end Intel CPU in a mining rig - yes, you CAN make a little back on them mining Monero but the PAYOFF is measured in years, as opposed to putting a cheap G-series Intel or using a FX-series or even a A-series AMD base instead.

 FX series CPUs in particular are ballpark $100 ($130ish for the high-end FX 8xxx series) vs *$300* ballpark for a Ryzen 1700 and MORE for that high-end Intel you listed, and the 8320E in particular is good for around 300-350 hash/sec on Monero (vs 400ish for the Ryzen 1700 and perhaps as high as 500 for the 1800x or that Intel).

 AM3+ motherboards also tend to be lower cost than AM4 at this point for similar capabilities (though no M2 on a lot of them, but M2 is a WASTE on a mining machine instead of using a much cheaper HD or USB key option), as are FM2+ motherboards.

 Recent price bouncing in the RAM market has also dropped DDR3 back to being cheaper than the same capacity of DDR4 (though it's still pretty close).


 The one down side is that AM3+ and FM2+ motherboards are starting to become less available, as some manufacturers have stopped making some models in favor of AM4 and whatever that slot the Threadripper uses (SM4? Can't remember offhand) based motherboards.

Using 3 phase to direct-power single-phase gear often puts too low a voltage on that gear to work properly - though most MODERN power supplies can handle 208 (nominal) input voltage.

 Most folks don't want to deal with the hassle and PAIN of phase balance - and most 3-phase electric feeds are to places that use gear that NEEDS 3-phase anyway, like large manufacturing machines.

 Large cryptocoin mines and large datacenters are not the norm in most areas....

 Looks like an "overloaded cables" issue.

 I'm actually estimating more like 200 TH by the end of October.

 Profitability will still exist - if you have low enough electric cost - it just won't be INSANELY high for those that didn't already HAVE miners by now or will get theirs in the next few weeks.

 I don't see X11 getting to the TB level on a single miner anytime soon. Too many of the current ones are already using the 14/16nm process node, not a lot of room to squeeze a lot more hashrate....

Micro Center is lucky they don't have a store in or near Central Washington - it would NEVER have any stock of AMD RX 470/480/570/580 cards for more than a few hours at those prices.

 Ballpark 35 Mhash/sec depending on where you can get the clocks to be stable at.

 ETH is a VERY bad choice for both the 1080 and the 1080ti, as GDDR 5x latency apparently has a bad impact on ETH hashrate compared to the GDDR 5 that the 1070 and below use.

 If the rumored 1070ti shows up with GDDR5, it might be the fastest ETH miner on the Green side - but will STILL not be competative with the Red side now that RX 470/480/570/580 prices have dropped back down to semi-close to sorta reasonable and availability is improving.
 I'm going to be VERY interested to see what it does on ZEC and the like where NVidia is strong - and what the final price turns out to be.

 Most Gold rated power supplies do noticeably better than 89% efficiency across most of their rated power range - EVGA and Seasonic in particular usually just MISS "Platinum" rating on their G2 and X series power supplies.

 Also, long term you aren't likely to be profitable at 10 cents / kwh - the last few months have been a noteable exception but NOT the norm - since most of the BIG farms are paying less than 5 and commonly closer to 3.

 There is "no competition" because the whole concept has nothing to do with cryptocoin mining, and is NOT APPLICABLE to doing cryptocoin mining.

 There is NO RANDOM to any cryptocoin algorithm - if there was anything random, the algorithm would not WORK.

 Whoever "PH" is, they appear to be running a particularly ignorant scam for this "speed miner", or their scam is aimed at the particularly ignorant.

 Intel and AMD are NOT "generic" - they just happen to be widely-available competing product lines with VERY similar capabilities and an overlapping range of performance.

 At least one of the ASIC miner chip houses (BW.com I think) uses Global Foundries as opposed to the more common usage of TSMC to make the actual chips.

 The foundries don't DESIGN the chips, they just make them to specification on contract terms (as they do for AMD and IBM and NVidia and Apple among MANY others - Samsung and Intel have their OWN foundries).
 The DESIGN of the chip is owned by the company that designed it.

3 phase distribution that feeds a single-phase (or a North American "split phase") setup generally uses a transformer to convert - which renders the "balance the phases" issue moot.

 23-24 perhaps with a stock BIOS on the 8GB cards with their faster RAM, higher needed modded BIOS with memory timing changes.
 I was seeing 21-22 on STOCK bios on my Sapphire RX 470 4GB "reference" type cards despite the slow RAM.

I would not even CONSIDER having anything to do with a single rig with 16 GPUs.
I don't even want to THINK about trying to cool such a rig in a 4u case - 8 GPUs would be bad enough.
Might be possible using a water-cooling setup, but the entire front of the case better be one BEEFY radiator and even then it's going to be marginal.

 Microcenter isn't in "the majority of the USA", though they are somewhat widespread.
 They're MOSTLY a "Great Lakes States" regional chain, based out of Ohio, with a FEW stores in some major cities not in their primary region.

 Fry's is mostly West Coast with a couple "out of area" stores in major cities, based out of San Jose California (unless they moved their HQ away from where their ORIGINAL store was at).
 Again, a big regional not a nationwide chain.

 It's also worth checking out Tiger Direct, they sometimes have some really good deals on GPUs.

 Bitmain delivering the first batch or two of the D3.
 Pinidea and Ibelink having probably delivered batches of their second-gen miners as well.

 Bitmain is estimated to have SOLD somewhere in the ballpark of 20,000 D3 units ALONE so far - which should all be delivered and online by the end of November. I think the estimated count was close to 15,000 by the end of October.

 Innosilicon isn't delivering A5 units YET - but those should start arriving in a month or so.


 This is not news - it's been discussed in several other threads, specifically including the D3 primary thread.

 The 1080 is mostly not popular due to it's high price - but for many algorithms it is very competative on hash/$ (just not on ETH which is what the majority of miners are interested in).

 It's a particularly good choice on ZEC and ZEN and the other spinoffs of ZEC, where it is a tossup on hash/watt AND hash/$ with ANY other GPU model (including the 1070 and 1080ti).


 This will change if AMD card pricing on the RX series drops much more, especially if those cards ever get back down to "close to MSRP" pricing.


 3x1080ti on a single 850 (even a GOOD one like the EVGA G2 850 or the Seasonic X850) will work reliably if you turn the TDP down far enough, but it hurts hashrate noticeably to do so which is a definite MINUS if you have a low electric cost.

 You are also leaving yourself a lot fewer options on possible future coins that might be efficient at higher power settings.


 The Gigabyte 1070 Gaming G1 has a TDP of 180 watts - that's 75 from the PCI-E bus, 105 from a PCI-E 8-pin connector that even the PCI-E SPEC allows up to 150 watts of draw from.
 You'd need to push it up past 225 watts to need a second power connector, per the PCI-E specs.

 The MSI 1070 card that has 2 power connectors is RATED for a 240 watt TDP (I've got one of those) - but I've never had it get much over 200 even PUSHING it, and the cooling won't handle MUCH more than 200 on that card without GPU overheating issues unless you have a VERY cool ambient temp and a LOT of airflow around the card.

 Sounds like a "decode above 4 GB" lack of address space issue.

 I don't know that board so I don't know where or if it has a setting to fix that issue.

 Easily will get you a viable 3-card GTX 1080 non-riser rig, possibly 4-5 card on a RX 470/570/480/580 or GTX 1060 based riser rig.

 1080 ti is still CLOSE to 3 a day - but not quite there this week even if you push max hashrate instead of max efficiency.
