per ethmine pool, there was an apparent DDOS attack on the Ethereum network forcing GETH offline.

Issue seems to have lasted about 3 hours and resolved about 30 mins back.

What little examination I've done of hashrate for Monero indicates a strong preference for AMD on GPUs and a lesser one for Intel on CPUs.

 I've not made the time to do any serious number crunching yet though.

Actually, for Ethereum, the memory size on the cards is CRITICAL - don't consider anything less than a 2GB card or it flat out won't work.

 For other algorythms/coins that probably doesn't matter.

 Also, anything older than the AMD 78xx/79xx series or the NVidia GTX 9xx or GTX 750ti is going to eat too much electric for what mining it can mangage to be worth investing time and effort into.

 *ANY* 2GB card should be worth looking at though, even if it's an exception to the previous line, as those were always either the higher-end cards or new enough to be worthwhile.

Mining on ANY laptop is very likely to overheat the laptop and cause it to fail quickly.
VERY BAD IDEA.

 In any event, Intel graphics are so low performance (AMD APUs blow them away, but even APUs don't mine very much on the stuff they CAN mine on) it's just not worth even trying.
 Intel CPUs are fairly good at CPU-centric coins, but more the quad cores and up and the Xenon many-cores intended for servers.

Seems to be the ASUS version of the Biostar board xlee linked and Phillip has mentioned using in some of his 4-card rigs, except older chipset.

 650 should be plenty for a dual GTX1070 rig - mine are all pulling about 550W but that's with a high-end AMD APU and a HD 7750 pumping out MooWrapper work in addition to the pair of GTX 1070 in each.
 I WOULD go with a beefier PS for a triple-1070 based rig, probably a 750 or an 850 to allow for later use of the system on stuff that pushes the power draw on the cards harder.

 If you're looking strictly at Ethereum, the AMD RX 480/470 are a much better option on a hash/$ ratio, but about the same on a hash/watt ratio to a hair worse.
 They're about HALF the cost but can pump out 80-90% of the hash.
 The only reason I went with NVidia on my last 3 rigs is that they were intended long-term (and long-term suddenly became NOW last week) to do other work with the Ethereum mining period as a way to offset some of the cost.

 That Gigabyte board should work OK for up to a 3 card mining machine, if you put a SHORT card (like the new Gigabyte "ITX" 1070) in the slot on the edge of the board to allow the middle board to get enough airflow. You'd need to use a case specifically designed for "8 periperal slots" like the Thermaltake Versa 34 or 35 (among quite a few other choices) to allow space in the CASE for that setup though.

 For mining, PCI-E bandwidth is NOT critical - only time you're pushing the buss at ALL on Ethereum (for example) is when the cards are loading the DAG file, which is a matter of a few SECONDS when the DAG changes (or when you boot up/restart the miner) normally every 5 days or so.

 Seems to be rather a bit of that happening the last week, after the big price spike - I know *I* switched all my 1070-based rigs over from Ethereum mining - sadly the older 9xx rigs are still making quite a bit more on ETH than on CURE and I can't afford to swap them over at this point.
 Do note that the large jump in users DIRECTLY correlates to when the price of Curecoin spiked - I for one have never seen whatever that video is that was mentioned earlier in the thread, but I DEFINITELY track Curecoin pricing and relative profitablility.


 Now if I could just get foldcoin working TOO (for what it's worth)....


 400k ppd for a little under 150 watts sounds like the AMD 480 - folding STILL does better on NVidia gear as my 1070s do quite a bit more PPD for a little under 150 watts per card, though the RX 480 seems to have closed the gap A LITTLE. I don't have any 1060, 1080, or Titan X Pascal rigs (much less any of those insane TESLA Pascal pieces) to compare on those.


 No, I don't have a warehouse full of GPUs, though sometimes I wonder about PS3Ed.....

Where's your pool address in your configuration?

 You're not telling your miner WHERE to connect to.

Shift to Ubuntu or XUbuntu 14.04 for now, it still supports fglrx where 16.04 does not, and a lot of the miner packages are available pre-compiled for it, if you're using pre-RX series AMD cards.

I'm not sure if fglrx was updated for RX 480/470 support.

Wood isn't all THAT easy to set on fire - if your rig is getting even close to hot enough it's going to be DEAD from overheating long before it's likely to be able to set a piece of wood on fire.

Boiling water is 100 degrees c by definition (ignoring minor variance for altitude/pressure and impurities) which is hotter than any GPU or CPU has ever been designed to run at - and those are the HOTTEST spots in a computer of recent design.

 People use wooden tubs to boil stuff in all the time, and have been doing so for MILLENIA.

 You won't see that out of a 1070 IME with the cards - my 1070s were pulling about 140 watts for 28 Mhs (watt figures from nvidia-smi, running Genoil latest).
 They did NOT pull anywhere near "31-33 Mhs out of the box", more like 25 or a bit over, and they're the high-OC Gigabyte Winforce models (most the 3-fan, last pair the 2-fan).
 More tweeking on mem clock and core clock gets the hashrate up a little more but then they start getting unstable and crash a lot.

 3 rigs, 2 x 1070 in each rig.

 I have no CLUE where your numbers are from, MINE are backed by the reported numbers on ethmine.org
 
 My R9 290s pull a bit over 30 MHs all day long rock solid despite being reference-card designs, but they eat a LOT more power due to older process used.

 5 cards, 3 in my "big rig" one each in a couple smaller rigs sharing with a R9 280x each in the smaller rigs.


 The RX480 is NOT the "top hash" AMD card for ETH, not sure if it even cracks the top 5 - it's just a tossup for the most EFFICIENT ETH miner out of AMD right now.
 R9 390/390x/290/290x are all better for sure on hashrate, and I think I remmeber someone saying they could get the Nano/FuryX up past 30 as well but not SURE on that last part.

I personally consider Windows 10 a DOWNgrade.
IMO go with 7, it has issues but nearly as bad as 10 has.

 For mining, though, LINUX overall is a better choice - but it does have a bit of a learning curve if you've never worked with it before.


 750ti isn't really worth mining <edit> ETH </edit> with any more, the CARD may have a low power cost but the total SYSTEM power draw overwhelms the small amount of mining a 750ti can do on ANYTHING.

 Which is why I moved from an area where I was paying close to 8c/KWH for 3/4ths of the year and over 14 the rest of the time, to a place I'm paying less than 5 yearround.

 You keep saying that but there is no such law AFAIK.

 US law DOES specify that the warranty only begins when the product is recieved, though - I've BEEN through that one once and won.

 Don't bother.

 Even if you COULD find software that would work, you're phone has such a low powered CPU in it you probably would be lucky to mine 1 Satoshi per DAY (a Satoshi is 1/100,000,000 of a Bitcoin) while using quite a bit more than that in electric usage, *AND* there is a significant probability you would overheat the phone to the point of causing it to fail VERY QUICKLY.

 Bitcoin isn't mineable even with high-end general computers any more for anything remotely resembling a profit - even the first few generations of Bitcoin SPECIFIC ASIC gear is unprofitable at this point unless you have free electric.

 

 Error.
 ETH runs faster on AMD than anything NVivdia, though NVidia can argue hash/watt especially on the GTX 1070 against even the RX 480/470 (pretty much a tossup there) and the 1070 is fairly close on hashrate vs the top AMD ETH cards - at TWICE THE PRICE per card.
 For pure hash, the R9 290 / R9 390 are still the kings, though the 290x / 390x are pretty much the same if you're willing to put up with their even higher power consumption - the extra cores do NOT help on ETH.
 384 bit wide memory access seems to make up a LOT for the slower memory speed vs. newer stuff.
 

 GTX 1070 DOES seem to be the sweet spot in the current NVidia lineup for almost any sort of mining where NVidia is at all competative.


 I haven't crunched numbers on XMR enough to have a strong opinion there, though I suspect some CPUs might be the sweet spot on hash/watt there.

 No clue about XPM, even as far as what that coin is actually named.


 3 card rigs make sense if you're putting them in cases, from a "ease of keeping all 3 cards COOL" standpoint.


 Seasonic actually isn't all that expensive when you start comparing against other QUALITY gold-rated or better brands.
 They does tend to have a small price premium against EVGA most of the time at the same power-rating and efficiency level, but if you wait for them to go on sale.....

 Enermax for me has been a mixed bag - have one of their Platinum units in my "big rig" that's been working well, but have had too many dead ones on other models.



 BTW - not sure what you mean by "go for the green" since pretty much EVERYTHING any more (except power supplies) uses the same small selection of chipsets, the same or VERY similar UEFI bioses, etc.

A lot of this depends on WHAT you want to mine.

 For most coins, a single-core or at most a dual-core CPU is plenty for up to 6 cards, and PCI 3 is an unneeded luxury.
 For most coins, AMD RX 480 / 470 cards are a much better option than the GTX 1070 - similar performance, similar power usage, half the cost for the cards.

 SLI is a NEGATIVE for mining. PERIOD. Do not use it. Ditto Crossfire if you decided to go AMD instead of NVidia.


 For a pure mining rig, I'd be inclined to go with that Biostar "Racer" 4-slot spaced out for 4 cards board and a low-end G-series CPU and 4 BLOWER-type cards, or with a AMD 990-series board and 3 non-blower cards (one a Gigabyte ITX to avoid cooling issues on the middle card, the other two probably Gigabyte Windforce or EVGA SC/FTW) and whatever the lowest-cost AM3+ Sempron I could find would be.
 I am NOT a fan of risers - have had too many issues with them - but a lot of folks have had good luck with them, and a WORKING riser-based 6 card setup is usually a little more efficient (but doesn't end up saving much if any money up front, just that it spreads the power used by "the system" across more cards at a time).

 AVOID AMD 970 series boards, they don't handle multi-card very well at all due to design limitations in the chipset.


 DEFINITELY go with a good high-quality power supply with plenty of power.


 Probability of achieving ROI is low, unless you can sell off some of the hardware in a few months at a small loss or some new "profitable" coin(s) show up in the meantime.



 Don't go with my "current rigs" as mentioned in other threads, those were never meant as "pure mining" rigs and I am just mining with them to offset SOME of the cost of building them.

It's not "by state" as utility companies don't cover entire states.
It's SOMETIMES "by country" as some counties only have a "County PUD" covering them - rarely one will cover 2 or 3 adjacent counties as a while in sparcely populated areas.

 There are a FEW counties in the US with utility rates in the under 5c/KWH range, but all of them seem to be in Central Washington state unless you're an INDUSTRIAL scale user - and not many more places even for INDUSTRIAL level electric using facilities.

 Industrial also varies - some places as low as 500KW can get you to Industrial level rates, some it's multi-MEGAwatt.

1) I don't mine BCN nor do I recall ever having heard of it.
  I have no data to base a recomendation on.
2) "smaller" cards mine so little they're just not profitable - any income they DO make gets swamped by the TOTAL SYSTEM energy burn.

 If you're looking for less expensive cards that are worth mining with at all, look at the older AMD HD7870 and bigger 7xxx series cards, anything less is going to be a total waste of money. The last 7870 I bought cost me $80, and they've dropped noticeably since then as the RX 480/470 were introduced a few months later. You might be able to get a HD 7950 in your stated price range by now.
 Down side - they're a lot more power-hungry than the current generation cards.

 Also, Windows 8 is not generally reguarded as worth using on a mining machine - too many issues.
 Upgrade to Win 7, downgrade to Win 10, or move to a LINUX based option (Ububtu/XUbuntu 14.04 is probably the most-used OS for mining with, though Windows might be able to argue the point).


 Why the heck are you using a consumer version of Windows for a bloody file server in the first place?
 You want something RELIABLE and STABLE in an OS for any sort of a file server.

Not sure if the PS3 CAN mine anything usefull. XBox 360 isn't even in the ballpark, but the PS3 spent some time as a DNet (and could be used for MooWrapper) and F@H champion, been long passed up bigtime by GPUs though and I'm not sure if it CAN fold current work.
