Mining ZEC directly via Flypool I'm currently pulling in about $3.75 a day gross on my 1070 ti cards - that is set for around 105 watts on each and pulling 460 sol/s ballpark, +200 core +700 memory on mostly EVGA SC modela and one Zotac Mini.
 The ASUS ROG Strix should be able to match those figures - my only issue with that model is that it doesn't appear to have ball bearing fans (same reason I won't buy any more Zotac mini models).

 At your power cost, that might be the highest-profit setting, though you might be able to get a LITTLE more net profit if you bump your cards up into the 110-120 watt range - efficiency drops but not a LOT, and the additional hashrate might be enough to cover the additional power cost.

 I don't push my cards any harder as I'm starting to run into limits of my infrastructure, NOT because my electric rate is high (it's very LOW).

 GTX 970 is a much lower performance card - if you're managing anything close to $1.50/day gross out of it you're doing good.
 The Nicehash estimator does NOT limit itself to 1 or 2 coins - odds are it was figuring a GTX 970 was more profitable on something like Lyra2rev2 (which often does well on the GTX 9xx generation cards).

 Gotminer's point about "at the wall" draw vs "card" draw is a good one.
 One of the reasons many-card riser rigs are popular is that they REDUCE the overhead power consumption and COST of "the rest of the system" on a per-GPU basis quite a bit vs running 3 or 4 card "no riser" setups - and the riser rigs are a LOT easier to get good cooling to the GPUs.

Ethhash on a 1080 ti is a total waste of the card - they make a lot more on equihash.
Keep in mind that the hashrate for ethhash on a 1080 ti is LESS THAN 20% better than the 1070, while their equihash hashrate is commonly more like 60% better.

 They are the best on Ethhash (ETH/ETC/others) overall (close on efficiency vs anything else, better on hash/$ vs anything else at recent pricing).
 They aren't even CLOSE on efficiency vs current Nvidia cards on equihash (ZEC/ZEN/ZCL/others) though they are in the ballpark on hash/$ at current pricing.
 They seem to be better in many cases vs current Nvidia cards on Cryptonight (XMR/others) but get blown away overall by Vega except on hash/$ if you have to pay a TON more than MSRP on Vega cards.

 That covers most of the "most popular" coins that are GPU mineable.

 All but one of my 1070 ti cards are EVGA SC "black" model.

 I just wish they'd quit being sold out everywhere most of the time - even EVGA is sold out on them a lot of the time.

 The other one I have is a Zotac Mini - works well, matches the performance exactly vs my EVGAs except it runs a little warmer (expected), but it doesn't appear to be a ball-bearing fan so it ended up being the last GPU I plan to buy that doesn't have BB fans.
 (I had Gigabyte non-BB fans start failing a LOT the week after I got this Zotac).


 Gamers are probably not TOO ticked at us miners this time around - the current round of price jumps didn't start 'till just before XMas, so most of them had plenty of time to get "XMas upgrades" done first.

 Welcome to the second big altcoin price jump of 2017.
 I was expecting issues to develop when I saw pricing on most of the major altcoins TRIPLE in a week - and they're STILL well over double what they were (mostly) 1.5 months ago.

If you keep the TDP on each card set to 200 watts, you should be fine. Perhaps 220, your MB/RAM/SSD setup is pretty low wattage.
You could push the TDP on the 4 cards that are NOT on the same PS with the MB/SSD/etc another 10-15 watts without issue.

 Push them to higher TDP and you will probably see a bit less stability up to ballpark 230/250 watt range, but you're seeing VERY poor hashrate gains by the time you get to that point, if any at all, so there's no real point in doing so.

 As I recall the CoolerMaster V series is Seasonic built, but has some really WIERD connections to the power supply and I'm not sure if it uses a good Ball Bearing fan.


 At the 225 watt level, each card should pull in the ballpark of 740-760 sol/s - probably towards the lower end of that range as they don't have the cooling of an Aorus which will limit how high they can boost clock on the core a little.

 If you aim for good efficiency, run them around 150 watts for about 620 hash/card seems to be at or very close to the best efficiency point, 125 watt level drops enough hashrate that efficiency DROPS a bit, 175 pushes around 680 which is still decent efficiency but noticeably starting to drop.

Actually, I forgot which thread I was in, and should have mentioned DSTM and "this one" instead of mentioning EBWF twice (once by name, once as "this one").

 I don't need splitters on any of my rigs, and I don't see much probability that I'll be using them in the forseeable future.

 I DO have a "2 6-pin to 8-pin" adapter in use on one of my older non-mining rigs, as it has an older PS that didn't have any 8-pin adapters on it but had a pair of 6.
 Been reliable for a couple-three years now, but it's also not exactly stressed running a GTX 960.

 Now that I know what you're talking about, I'm going to point out that those EVGA cables aren't "splitters" as such, they're the original power supply cables for that model of PS - and likely are NOT the same pinout on the input as a PCI-E 8-pin power connector.
 I'd give odds in favor of there being *4* +12VDC pins in use on the "input" end, not the 3 of the PCI-E spec - might possibly be 3 +12VDC pins and a sense line on one side though, where PCI-E uses 3 lines on one side for +12VDC and the 4'th for a spare (and excessively redundant) ground.

 Vegas do Lyra2Rev2?

 I've never seen a benchmark on them there, thought they were all hammering out Monero (where they ARE the definite king if you can get them for a reasonable price and don't mine Windows 10 low stability).

 ETH on a 1070 ti is a waste - the 1070 hashes the SAME, why pay 10% or so higher for the 1070 ti to do ETH on?

FTW should be good cards, but the dual power connector makes them harder to deal with in a multi-card rig.

Gotta wonder if EVGA knows why the SC model is such a big hit.....

Duke is dual power connnector.
Not sure on the others - they have at least ONE model that runs from single 8-pin but I don't remember which one it is (other then their blower model).

IIRC the Titanium and the Gaming are the same card except for the color scheme.

Sounds like you are pushing overclock on at least one card a bit too hard.

 ETH is very hard on memory access, but very EASY on the GPU itself on most cards - equihash mining is a LOT harder on the GPU itself not as memory intensive.

 Settings that work well on one may not work well on the other due to those differences.

He said algorithm, not coin.

 I can't speak specifically to most algos, but the 1070 ti is THE most efficient Equihash miner on the market at this time when mining for efficiency (except the Titan V, but THE COST THE COST OMG THE COST OF THAT MONSTER).

 Claymore dual miner is ETH base - which is a VERY BAD choice for the 1070 ti as it doesn't hash ethhash any better than the 1070 non-TI and makes a lot more on many of the equihash coins (ZEC/ZCL/ZEN and such).

 Lbry or LyraV2r2 should also be good choices, but I've not actually tested on those.

I gave up "chase the profitablity" a while ago - too much work and by the time I get all my rigs switched over TO the new "high profit" coin it's probably already dropped back down again, and you ALWAYS lose some income as you are doing the switch.

 Even if you DON'T chase profitability, you still benefit SOME as other folks move their hashrate OUT of the coin you're in to something else, when the difficulty drops as a result of the hashrate drop.

 IMO it would be better to leave most of your RIGS on the "basic coin" for paying the bills and use a few "specific" rigs to go chase the new coins for long-shot "surge" returns.

 Depends on how many rigs you have though - not practical to do that if you only have one or 2 rigs.

Most LINUX mining software specifically supports Ubuntu and it's offspring, like XUbuntu (my usual flavor) and pretty much ALL of the "mining-specific" distributions like nvOC.

Windows drivers are a lot more limited on how many cards they can support, though AMD supposedly is adding or recently added support for up to 12 cards on one machine under Windows.

LINUX ... I'm not sure if LINUX drivers HAVE a cards limit, other than "how many cards can I get physically attached to the machine and working".

 Monero, therefore more like 500ish hash on the RX as I recall (definitely under 1000).

Compared to a year ago, pretty much ALL Cryptocoins are high yielding.

Right now, the RX 570/580 cards probably have the best ROI - but it's close, and if AMD Polaris card pricing keeps climbing that might change AGAIN.

 *IF* you could get reference-model Vega cards at close to their MSRP, they'd be the best - but try finding a Vega at ALL lately, much less near MSRP.

1200 watts for that combination of cards seems a LITTLE high, unless you're running something less efficient than an 80Plus Gold rated power supply.
I suspect you need to do some optimization work on TDP settings and clock settings.

It's normally best to run seperate miners for the AMD and the NVidia sides, as the two are almost always NEVER going to have the same coin/algorithm be the "most profitable".

 That can vary sometimes on the specific card MODEL, much less on the Team Red vs Team Green great divide.
