230. On a GTX 1070.

 Ouch.

 No WONDER they thought they needed the extra connector. They DO.

 That's more than any of my GTX 1080s use (they're Gigabytes with a high factory OC and a "raised" 200 watt TDP).

That power supply SHOULD handle those 6  cards - if you keep the TDP no higher than 100%.
 It will be a LOT happier with the cards at 80% or less.

 TDP on that particular card at factory settings (I have 3 of them) is 155 watts, NOT 170.

 Best settings for ETH is normally "max overclock your ram can handle, then drop TDP 'till the hashrate starts dropping noticeably".
 They should handle at least a +400 (afterburner setting, or PrecisionX as I recall works the same on that) overclock on the RAM with good reliability.


 If your PS is making "wierd noises" though, you might have a failing PS. Even Seasonic has occasional "infant mortality" issues.

The P104-100 per all of the data I have been able to gather

 (1) probably will have some BIOS tweeks to enhance mining performance - but DON'T expect 60 Mh/s, I'd guess 40 at BEST and more likely 30-35 on ETH
 (2) should be a BEAST on ZEC - though not quite up to the GTX 1080ti.
 (3) should have 20-30% lower power usage at the same clocks vs the GTX 1080 consumer cards, due to no video circuitry and disabling the "video-specific" parts of the GPU.
 (4) might have a MSRP of $350 - it definitely needs to be lower than the consumer cards to generate significant interest, given the short warranty and much lower resale value
 (5) no release date has even been interested.

 No FIRM information has been published to date, so far it's all rumors and leaks.


 I have a strong suspicion, given more info has surfaced about it from more sources, that the P104-100 won't show up for 2 weeks to a month after the P106-100 - and that has had dates anywhere from late-June to mid-July attached to it.


 Then there is the alleged 106-based mining machine - that appears to be using a mobile or modified-mobile version of the GTX 1060 (similar to the PandaMiner using mobile RX series cards).
 That however I've only seen ONE actual source of info on - and a lot of "quotes" of that one source.
 Not calling it vaporware - but so far it's pretty short on hard info.


 wcctech is one of the sources on the P106-100 - but they have a VERY spotty record, given their multiple articles about a "RX 490" that never happened among other "scoops" that didn't exist.
 To be fair though, they HAVE had some successfull scoops.

Won't affect me much at all directly - I only have one rig mining ETH any more (3 x R9 290), and I'm considering moving that to do Dnet/MooWrapper/BOINC work anyway.

 Indirectly, I don't expect much change - the stuff I'm doing on most of my rigs is (1) Scrypt ASIC, or (2) not something AMD is not at all good at which limits my exposure quite a bit when the vast hordes of *mostly AMD* ETH mining cards start looking for new homes.

 I also get a lot of risk reduction due to being in The Land Of Low Cost Electric - even when profitability drops to the point most miners would be losing money, I'll still be profitable - just not as MUCH so.

 On the other hand, I'm very happy I finally found a place with decent power availability, room and power capasity to grow INTO, and current profitability is LETTING me grow (and will probably let me do some "upgrade to more efficient gear" before it matters on my older GPUs).


 The price of ETH has ZERO effect on the probability of it going POS. They are NOT connected in any way, shape, or form.

 I also don't see it going POS as being likely to have a significant long-term or even much of a short term effect on it's price.

Your power supply should handle 2 x GTX 1060 without issues.

 More than that will probably be a problem, it only seems to have 2 x PCI-E power connectors.

Well, it would appear someone was listening, the "new" version of the site got rolled back to the old version.

 Hopefully the next experiment will work out better.

It's better IMO to set a custom fan curve as opposed to messing with trying to throttle the card.

 If you're getting to 80C on an Aorus, you either have your fans set WAY too low, or you have very poor cooling to it.

 Not cheaper, been out of production for 1-2 YEARS now and almost impossible to find - and when you do find one they get a premium pricing pretty much ALL the time.

The 1000 provides more power - but has a junk sleeve-bearing type fan that is NOT good for longevity at high temperature and load levels like a mining-used power supply will normally see.
 IMO if you can find one go for the EVGA G2 1000 or the P2 equivilent, or the 850 versions, depending on how much power your rig actually needs.

 Given how hard GTX 1070 cards have been getting hit in the last week, I disagree with that last statement.

 I don't see the "difficulty bomb" mattering, and don't understand why ETH wasted the time to create it - as it affects all miners equally, it isn't going to change profitability at ALL on a per-card basis.


 The "phase in" aspect of the current plans to move ETH to PoS might soften the landing when all those ETH cards start looking for new homes - but it's still going to be brutal eventually, unless the current price jumps resume before that point in some of the other bigger coins like ZEC.
 We're also talking sometime NEXT year it looks like before it becomes a significant issue - though ETH has had to "delay" plans for the PoS transition before....


 It's not stupid for a miner to sell their coins immediately - it's sometimes "I have BILLS to pay", it's more often "I don't trust this coin to stay at this price" or "I don't trust the volitality".
 Keep in mind that coin prices are NOT automatically going to go up - Bitcoin was well over $1000 at it's earlier peak, then dropped as low as $200 and spent a LONG time under $500.
 Litecoin hit it's all-time peak near $50, a year later it was more like $2 and spent a LONG time under $5 - and I don't think it's EVER gotten back to that all-time peak (though this last week it got very close, one way or the other).

 Then there's the bear in the woods that far too many cryptocoin devs keep ignoring - outside of Bitcoin, ETH, and Litecoin, how many coins have significant acceptance in The Real World?
 In fact, I probably shouldn't include ETH and LTC in that list as both combined don't get accepted at 10% as many places as Bitcoin alone does.
 Without the ability to spend the coins in The Real World, they have zero chance at long-term viability.

The R9 290 is probably best used on ETH and it's clones like ETC at this time.
This has been generally the case with occasional "hours-long" periods of exception (and a VERY short period when ZEC was first introduced, first 2-3 days or so) for at least the last year.

ZEC network hashrate is at an all-time high right now - by a narrow margin over a short spike a couple weeks back.

 A lot of miners WILL chase the "most profitable" coin - which is why I tend to refer to "the basket" of coins that have similar profitability, when one moves miners shift and even them out.

 Right now the basket is huge - TONS of high-profit coins to choose from, more than at any other time in the short history of Cryptocoin Mining.


 5 years from now, miners will probably be looking at this timeframe we're in right now as "the golden age" and the Litecoin/X11 craze days as "the silver age".

 Which is about the same to a little MORE power than the 750 ti needs.


 So many options for making good money with GPUs the last year and change, then the price rises hit over the last couple months and change.... 8-)

It's going to take a HUGE drop in profitabilty before folks start losing money from operating a miner.

 It'll take quite a bit less to drop ROI to a level most miners will find unaceptable though.

 Too many folks getting SPOILED by the "less than 3 months" ROI on a lot of rigs right now.

 The Mini-ITX cards are good for non-riser rigs as a "manage cooling airflow" tool.
 I don't prefer them to full-size cards, but in their place they're VERY usefull.

 ETH is going to take more than a few weeks to be "useless" - even with the "mining-bomb" the only difference will be that total network hashrate might drops, but how much you mine PER CARD isn't going to change much if at all due to it - keep in mind it affects ALL miners EQUALLY.
 I've never really understood WHY the "bomb" was ever implimented, as it has no REAL effect on mining.

 Nicehash is a marketplace - you rent your machine to them, they then sell it's hashrate (to be picky, they sell each card IN your machine's hashrate as a chunk) to the "buyers" in the marketplace, then Nicehash pays YOU that income less a "handling fee".
The buyer then points the hashrate at a pool of their choice to earn THEM coin.
 That's the short-form version - I left a ton of details out.
 
 As has been mentioned in many threads, the GDDR 5x memory used by the GTX 1080 and 1080ti has much higher latency levels than the GDDR5 5 used by the 1070 and down.
 This latency is a major minus for ETH (and clones) mining (which is VERY strongly memory-limited), leaving the 1080 hashing ballpark 15% slower than the 1070 can manage on those coins.
 This is probably why the 1070 is selling out like hotcakes right now while the 1080 doesn't appear to be seeing a lot of mining sales - the 1070 is a better ETH card and ETH is the "big gorilla" in the GPU mining world.
 I haven't bothered looking to see how availability is of late on the GTX 1060 models, as they don't work all that well for what I'm doing with my machines.

 *looks at my profits from the last year of mining, ROFLMAO*

 If mining is never profitable, explain how bigger miner companies like MegaBigPower (aka GigaWatt) stay in business and keep growing their mining operations.

 Mining RIGHT NOW is more profitable on GPU-mineable coins than it has EVER been - and I made quite a bit back in the Litecoin mining craze, enough to buy several of my current GPUs out of the profits.



 There seems to be some confusion though - the "mining system" appears to be based on a mobile or modified mobile version of the NVidia 1060 (similar to the mobile AMD cards the PandaMiner uses), that is NOT the "P106-100".

 The P106-100 (and P104-100) are supposed to be stand-alone standard GPUs except for having no video output (similar to some WORKSTATION GPUs like the long-running AMD Firepro-S series).

 Not true. GTX 750ti is STILL one of the most efficient Monero mining options, and some of the other NVidia cards are pretty efficient at it as well.

 With that said, though, XMR isn't a good NVidia mining choice except for the 750ti and POSSIBLY some of the LOW-end 9xx/10xx series.

For Skein, the Alexis 78 miner does quite a bit better than any of the alternatives.
 I was seeing close to 20% improvement over trpuvot version on my 1070s and 1080 I was testing on for a while.

 60% TDP, that's quite nice.

 They'll pull 28+ at higher settings, but I've not played with targeting efficiency on them for ETH.

 I'd be inclined to do my testing on ethpool vs nicehash though, given how nicehash likes to bounce cards around as their market shifts and the cards get shifted to different participants in the market.

 The 60 mh/s quotes for the P104-100 are VERY unlikely to be lived up to or prove to be close to accurate.
 The GTX 1080 that card is based on doesn't even manage 30 Mh/s (more commonly 24-26 ballpark), as the GDDR 5x memory it uses has seriously worse latency than GDDR 5 as used in the 1070 (which only manages right around 30 Mh/s in most cases, rarely as high as 32 if you get lucky in the silicon sweepstakes on you memory ability to overclock lots).
 
 Even the GTX 1080ti with a TON more cores than the 1080 only manages mid-30s ballpark.

 I flat out do NOT believe the P104-100 will be capable of even 40 Mh/s on ETH, and would be amazed if it managed 45 - even if it moved to GDDR 5 instead of 5X it's STILL not likely to manage 40.

 On the other hand, nobody sane tries to mine ETH on a GTX 1080 or GTX 1080ti - they mine ZEC and it's derivatives, skein-based coins, groetsl-based coins, libr and derivatives, and such.
 The P104-100 should be very nice for mining THOSE coins.


 The one BIG advantage of these cards will be power efficiency - no video circuitry, the video-specific parts of the GPU chip probably disabled either on the chip or in the BIOS (similar to what TheStilt did with his line of R9 290(x) modded BIOS from Litecoin mining days that reduced the power draw on those cards a LOT), I suspect that the minining-specific versions will see 20-30% less power draw at the same clocks vs the consumer versions.

 They may gain SOME hashrate via BIOS mods to improve memory latency (AKA "strapping" as used on the RX series), but I suspect those gains will be less than 20% and might not manage 10%.

 None of the rumors I've seen so far mention HIS or PowerColor, but I would not be shocked if one or both of those jump on this bandwagon.
