I have a "startup.conf" that I point XFCE at to autorun on startup.
I'm not sure if it matters to nvidia-smi or nvidia-settings, but aticonfig DOES need X to be running before it would let you do a lot of it's commands.

 I never had any of the orbs, but I suspect there are folks that would like to upgrade those as well.

 You have to have the breaker anyway, no matter how you set the circuit up.
 Same on the power cords.

 When I rewired the heaters in my current location, it cost me less than $50 ALL UP to set up a pair of 20 amp 220 circuits with 3 outlets EACH (though 20/20 hindsight I'm thinking I should have put 4 or 5 on each - I might end up changing that eventually.)
 I have NEVER seen a PDU that was $25 or less unless it was broken.

 Amazon specifically prohibits the use of AWS for cryptocoin mining.
 I'm not sure if Azure or Google's cloud service does so specifically.

 Depends on how many ports with viable spacing the machine has, or if you are going to use a hub?

Monero is a rare case (perhaps the ONLY case) where a GPU and a CPU can BOTH mine it profitably.

 The highest hashrate actually comes out of CPUs (some of the Intel server multi-core stuff, and AMD Epyc and Threadripper) but since you can normally set up a lot more GPUs in a rig than CPUs and some of the GPUs are pretty high hashrate, the highest hashrate RIGS are probably mostly GPU based.

 However, there are usually more profitable things those GPUs CAN mine.

 stak-xmr (something like that) seems to be the preferred Monero miner at this point - there are both CPU and GPU varients of it.

My first reaction when I saw the title was "oh neat, can earn coin via gaming now".

 NOT a good choice for a blockchain project IMO.


 Also, doesn't the ICO part violate the recent Chinese government "ICOs are illegal money raising" ruling?

nvidia-settings -a "GPUFanControlState=1" -a "GPUTargetFanSpeed=70"

 I don't think it works without the quotes, but not 100% certain.

For a straight-up mining rig, the only thing that matters in a motherboard is that it will actually WORK with the number of cards you can attach to it reliably.

 The spacing on these boards should be IDENTICAL.

 Slot spacing is part of the ATX specification.


 If I had to build a riser rig, I'd probably go for the H110 as ASRock has given me generally good results out of their motherboards and it supports my preference for using PS/2 ports for keyboards and mice.

 I'd actually prefer to go AM4, but I've yet to find an AM4 solution that I thought was a GOOD one for a mining motherboard.

 1) It's probably a little worse than that - my best estimate is that Etherium has about 60% of the GPUs currently used for GPU mining, and might be as high as 70%.

 2) "Soon" is actually sometime next year, *IF* they actually hold to their current roadmap. They're not even planning to START experimental work with PoS prior to about December, and THAT is going to be a "1% POS 99% POW" split for likely quite a few months as they test and debug the POS implimentation.

3) Based on my estimate from 1) it will likely more-or-less triple difficulties over the first month after Ethereum goes to a full POS model on all other GPU mineable cryptocoins (except XMR which still has a substantial CPU mining presence).

 These estimates are based on current pricing staying fairly stable (give or take 20%), a major price move WILL change things dramatically.

 I remember seeing notes on specific AM4 boards that use of the M.2 slot will sometimes disable one of the GPU slots.
 I'm not sure if your board is one of those, but it seems like *ALL* of the AM4 boards with more than one PCI-E 3.0 slot "shares" lanes between the second slot and the M.2 connection.

 For some reason MB makers seem to dedicate 16 of the 20 (for Ryzen) PCI-E lanes to the first GPU slot on ALL of the boards I've looked at, and have to share out the other 4 among everything else.

 Any AM4 board I've looked at to date with 3 x 16-bit slots use PCI-E 2.0 from the chipset to run the 3'd slot, usually at x4 or "share" x4 with other stuff.

 They are violating Amazon's terms of service when they do so, and CAN be shut down without notice or refund over that practice.

 

 And they're also insisting on folks that did so prior to that ruling return the funds they raised - guess China doesn't believe that Ex Post Facto laws are a bad thing.

It might be less expensive to just wire up that 220v circuit with more than one outlet.

 There is NO REASON you can't do so - it's just not the norm in North America since most "220 outlets" are intended for high load items like electric driers and electric water heaters and central air/VERY high capacity window air units that DO soak 15 amps or more even at 220 while low-load items are normally wired for 110.

 DON'T do this if you don't know what you are doing though - just like ANY electrical work.

 Wallets don't support stratum - the A2 CAN be configured to use getwork, I don't know if that's possible on the L3+ since I don't have one.

 Look into a stratum proxy for Scrypt to connect to your wallet, then connect the L3+ to the stratum proxy.

 I have to wonder how well a "pod" designed to upgrade the Gridseed "80" blade units would sell....

 I had no issues with setting up the H270-hd3, but in 20/20 hindsight for what I was building the system for I should have gone with the "sli" varient.
 On the other hand, I never inflict Windows 10 on a mining rig - LINUX by preference, Win7 otherwise (and yes, Win7 WILL install on a Kaby Lake CPU if you don't insist on using USB keyboards AND mice and works fine once you get the MB drivers installed).
 Board should work fine for a 3-card no-riser rig - my issues with it weren't mining related or with it not working.

 If that is the blower model and the cooling on the Asus 1080ti Turbo is as bad as on the 1070 version, I would avoid it.
 SERIOUS cooling limitations to that system largely but not entirely due to the severe airflow blockage of the mounting bracket - they might be WORSE than the Founder's Edition cards for cooling.

 Aorus 1080ti and the Gigabyte Windforce 3 fan models work well.
 Down side of the Aorus is the 3 card width - but for a riser-based mining rig that shouldn't be an issue.

 I ran a small farm on a junky Virgin Mobile 3G connection for a while - latency wasn't an issue.
 I then ran it for 2 years on an Exede Sat connection - lost less than 1% stale shares due to the inherent 600+ (more commonly around 700) millisecond latency.
