A well dialed in 1080 can pretty close match a 1070 ti on efficiency - but it's also going to do about the same hashrate when it does so (WELL under 5% difference and commonly 1-2%) - which is NOT worth the ballpark 10% higher price on comparable models for no better efficiency and such a tiny gain on hashrate.

 No reason to use anything more recent than 373.06 on a mining machine, unless you have 1080 ti cards or 1070 ti cards that aren't supported by that old of a driver version (possibly some of the Pascal-based Titan version as well).

 80% of the power supply RATING will show as somewhat more than that on a wattmeter, due to the power supply CONVERSION LOSSES.

 The RATING is how much power the supply is rated to supply to the load, NOT how much it is rated to pull from the wall.

 Even with MY curiosity, I'm not going to waste time trying to get mining running on my old "now a media center" P4-2000 based machine.
 Doesn't help that it's running 2k, and the oldest OS I know of that supports a Monero miner at ALL is XP.

 About the only way I can think of that you could "mine" on a Pentium 4 is to run the Dnet RC5-72 client via the MooWrapper project on BOINC and earn a microscopic amount of GridCoin - but you will NOT earn enough to pay for the electric usage or even close.

 In the USA, standard "space heaters" are almost always 1500 watts, sometimes with a lower 750 setting or 2 lower settings around 500 and 1000 watts.

 ASIC miners are, in my experience with recent ones, ALL loud (the ones that aren't are old USB-based stuff that were very low capability).

 GPU rigs though can be set up to be pretty quiet, especially if you target the GPU power setting to around the most efficient operation area of that GPU.

I have VERY cheap electricity - and I also have a bunch of rigs that were originally built for Folding that are slowly getting converted to riser rigs that can handle a lot more cards that way.

 I'm also only at about 50 perhaps 55% of my max power capacity in my current location, though I'd have to start building completely new rigs again to push much closer to THAT limit.

No, because Bitcoin is all mined by ASIC that can ONLY do one specific crypto algorithm, and nothing else.

 In a more broad sense, the level of power consumption used by Bitcoin mining if it was applied to properly designed GPU rigs (don't build it as 1x PCI-E lane riser rigs for FAH) could generate a TON of work pointed at FAH or BOINC or the other less-well-known distributed science projects.

 It would be perfectly reasonable for Russians - but I certainly would not be interested in moving there to mine if I wasn't a local.

Not so much an "oversupply" but a lack of "overdemand" compared to the last 6 months or so.

 Laptops WILL overheat and die if you stress them too much - I HAVE had to repair some that folks admitted running stuff like the DNet client on (which is a cryptographic-type program that is VERY similar to many mining algorithms in how it stresses a CPU) or Prime95.

 Thermal throttling has limits, and most laptops PUSH those limits very hard to achieve the level of performance they DO manage to get to.

 Also, it's not always the CPU ITSELF that dies - it's often the motherboard because parts on IT are overheating due to excessive high-stress workload - like the power conversion circuitry.


 Not all RX series cards use cheap sleeve bearing fans (and not even all Gigabyte cards do) - reference Sapphire and the Gigabyte "Aorus" line - though far too many do so.

ETH mining on the GTX 1070 is a bad idea - the ONLY reason the 1070 got used as a ETH mining card is that the good AMD ETH mining cards for a while were in the SAME PRICE RANGE (and both got into the same range as GTX 1080 pricing for a while), so it made sense THEN to spend $450 on a GTX 1070 that would mine 30 Mhash/sec with a hair better power efficiency than a RX 470/480/570/580 that would "only" manage 26-29 Mhash/sec after BIOS modes for ABOUT THE SAME PRICE.

 Now that the RX cards are consistently available at 60% OR LESS of the price of the 1070 and still dropping towards pre-shortage pricing, there is no reason to even CONSIDER ETH mining on a 1070.

 Nobody ever even ANNOUNCED a mining-specific GTX 1070 model, and it's starting to look like the "mining specific" 1080 model that was rumored may have turned out to be the GTX 1070 ti instead.


 At least one and I believe 2 models of the Sapphire RX 470 "mining" card line are specified to have Samsung memory - but those Sapphire mining cards are the only ones I have seen where the memory brand IS specified.

ETHMonitoring feedback.

In "dark theme" both the "remove selected miner" "add miner" and "theme" buttons are completely unreadable - black text on a VERY dark background.
The mining monitor area in "dark theme" is hard to read - a DARKER background would help a lot, the contrast is low with the current color choices.

It is irritating having the positions I move the various bars to (like Hasrate 1, Host, and such) reset upon reboot.
It is also irritating that the program doesn't even ALLOW standard Windows statup settings for "size" and "location" to be set.


 On to suggestions:

If the hashrate on a particular miner or GPU goes to 0, have the color change to red.

Monitor is going to be UNUSABLE for rigs that have more than about 7-8 cards per rig as currently configured. Really need to split the GPU hashrate and power/temp lines out, perhaps at the 6 GPU per rig point?

It would be nice to be able to remove some of the "bars" entirely from the listings - I don't have ANYTHING that needs 2 "hashrate" (I'm guessing that's for Claymore dual mining?) as an example.

 No.

 It's an issue with how Nicehash works - your hashrate gets switched to a different user fairly often and any work that was "in process" at that point automatically becomes outdated when the switch happens.

 VERY FEW 1070 cards need more than a single 8-pin (or 6+2 pin) PCI-E power connector.
 Ditto 1070 ti cards - I'm not aware of ANY of those (so far) that need more than one connector.
 1080 it's more common but a lot of them are still single connector.

 That monster MSI Gaming thing with the 240 watt TDP rating is the only one I know of for sure, but there MIGHT one or more others I'm not aware of.


 SATA is a VERY VERY BAD IDEA for riser usage - the connector ITSELF is only rated for 54 watts MAX (3 connectors at 1.5 amps each), the PCI-E spec calls for up to 75 watts draw out of the PCI-E BUS connector and many cards have been shown to pull a little MORE THAN THAT (specifically including some AMD RX 470/480 cards).

 "MOLEX" connectors on the other hand are rated for 13 AMPS per pin used (normal computer usage is 1 x 5 VDC, 1 x 12 VDC, 2 grounds) for 156 watts rated capacity - which is PLENTY for PCI-E bus power.

Most of my rigs run the Seasonic X-850 gold (which sadly is no longer in production and low availability) though I have one running the Seasonic SS-860 model (basically the Platinum version of the same PS) which DOES still seem to be available.
A few (noteably my B250 Pro 19-slot MB based rig using 2 PS so far) run the EVGA G2 850 (which has variable availability lately, not sure if it's still in production or not offhand).

 There are also 750 watt versions of those power supplies, and EVGA has their P2 line that are Platinum versions of the same supplies.

 Cooler Master and Corsair are HIGHLY VARIABLE on their power supplies (to be fair, so is EVGA) because they don't make their own supplies and different models are made by different manufacturers, some good some garbage.

 I strongly recommend AGAINST the Seasonic "Focus" and "Prime" lines, and the EVGA G3 line, as they moved to using junk "fancy name" sleeve bearing fans THAT DO NOT LAST IN A HIGH TEMP HIGH LOAD ENVIRONMENT LIKE MINING.


 6 x 1070 running at EFFICIENT settings will be OK on a good 1000 - my 5 card rigs with a mix of 1070/1070ti/1080 at efficient settings (100-110 watt TDP) and high-power-usage FX-83xx CPUs fit comfortably on those power supplies I mentioned above.

 PCI-E connectors are enough, if you power your risers from MOLEX - but the cards that have to share a "dual" PCI-E cable might be squeezed a little too close for GOOD cooling. Worst case, angle them away from each other at the bracket end.
 The Seasonics are better there, as they have one more "PCI-E" designated connector on the PS (and only have to use ONE dual cable) than the EVGA model does - though EVGA gives you a bit longer cable length between connectors on their "dual" cables.

2)  ALL Ethhash coins have a DAG file - I believe that the smallest is in the 1.5 GB range but I might be off on the LOW side as I've not actually looked at all of them.
     DAG file usage is part of the algorithm.

1)  The real limitation on other algorithms is the compute capability of the GPU, not the RAM size.
     The GTX 1060 is a special case, as the "3GB" model does NOT have the same core count as the "6GB" model - they should be counted as DIFFERENT CARDS and IMO Nvidia is arguably guilty of false advertising by calling those 2 cards the "same model" of GPU.

3)  You are a painter or a carpenter.

 For standard ATX supplies, 1600 watts is the limit because they're all designed to be useable worldwide - which INCLUDES the USA with it's very common 15 amp 110 volt circuits that anything bigger WOULD OVERLOAD.

 For server supplies, outside of "specific designs for mainframes" and such, the largest widely available PS I'm aware of is a Delta model that is rated for 2400 CONTINUOUS watts output with 220 volt input.


 For perspective, a 30 amp 220 circuit (which is common in data centers, usually on a L6-30 "drop cord" from "tracks" hanging from the roof) is only good for about 6.6 KW INTERMITTANT usage, or a little over 5 KW 24/7 continuous usage - which fits *2* of those Delta supplies comfortably on one circuit.


 Keep in mind that the power density of ASIC Cryptocoin mining machines is extremely HIGH compared to almost ALL computer hardware - most file servers and web servers use less than 300 watts in a 1u case, which has MORE cubic inches than a Bitmain S9 or any other similar-form-factor ASIC miner.

 It's also why you aren't seeing ANY miners hit wide distribution with a power draw "at the wall" much over 1400 watts.

 Sure there is.

 Filtered air INTAKE and positive pressure design.

 If you have POSITIVE pressure in the room infiltration isn't an issue.


 I suspect most mining rooms are negative pressure because folks ASSUME that a "gable" type fan can ONLY be used for exhaust (it's what they're designed for, but they CAN be used for intake with proper design and installation).


 I do the positive pressure filtered intake more due to MY issues with dust and smoke and such vs for the miners though, especially after last summers massive "smoke from many many forest fires upwind" issues in my area.

ANY mining setup will generate heat - for most of us the issue is "heat removal" not "enough heat".

 Error.

 They have FREQUENTLY had "small batches" a day or three after a new batch on ALL of their current miner models, due to payment failures leaving them with machines that they THOUGHT were sold but ended up being available after all.
