Great news.  I mined RVN pretty much exclusively last month and have a little over 100k sitting in my local wallet.  I'll keep hodl'ing through the summer I think, to see where it goes.

I got all my rigs on ZEN now and plan to setup a secure node by the time the 20% reward kicks in and then possibly keep going and switch to a super node if I ever get to a 500 coin stake.  IF RVN really blows up, maybe I'll consider selling it for ZEN to get my super node going sooner rather than later.

On the solar, I have a 35 kWh system, and generated 3,500 kWh last month as the sun finally decided to come out here in Virginia.  As you can see from the below graph, having a month or two with lots of cloudy days make a huge impact:



And here's a power graph from yesterday:



I need to get out there to rinse the pollen off the panels as that does reduce the output quite a bit.  I also have several micro inverters I need to replace.  And the heat (it hit 90 yesterday), doesn't help.  Solar panels like it nice and cool (but sunny).

But despite generating 3,500 kWh in April, my power bill is still trending in the wrong direction.  The days of not having a power bill (prior to August of last year when I started mining) are long gone.  



I'm at 128 panels, and plan to add another 24, which will max out my current solar breaker panel.  After that, I'll likely switch from micro inverters to larger 10KW inverters and run DC from the arrays back to where the inverters are located.  This makes sense since additional arrays past the initial 152, are going to have to be located further away from my shop where all the miners live.  High voltage DC power = much less power loss than 240VAC.

Making decent progress on the "mining room" I'm building inside my shop building.  I got a 96" wide by 84" tall wide span ULINE shelving unit with 6 shelves.  That guy is able to hold all my GPU rigs and ASICs with room to spare.



I'm feeding it via 4x 30A circuits that in turn feed HP 24A PDU's and have 12A PDU's connected to them.  Fortunately the breaker panel is close by, so the #10 runs are pretty short:



I built the walls and ceiling and put some cardboard up temporarily to force the air through the rack.  I hope to get some drywall up this afternoon.  So cold air is pulled in from the outside, forced through the rack, and then extracted from the gable vent.



The side walls are 96" wide, just like the shelving unit.  So once I run out of room on the shelf, I'll replace the walls with additional shelves except for an access hole for inside maintenance.

just cut the wire and coonect

So about 9 months from begining of this thread we are still surving somehow,yeah i know asics are coming but still we have some profits from mining.5$ per 1080ti a day still isnt that bad,yeah i know that it was much easier when we were earning 20$ a day but still its not that bad

We did a couple solar quotes a month or so ago and we were getting figures of $150,000+ for a 86,800 watt setup. That was after the ~30% government rebates but it did include installation. That quote was way out of our budget, but for the price your were quoted I'd be tempted to install myself  (if I was young and healthy again) or find a local general contractor to do it.

 Once the card reaches around 83°C, the clocks level out at around 1705 MHz, which is still 100 MHz higher than the base clock.

^^^^still higher than base clock, and those few mhz make basically no difference in the real world.

Here is one of my GTX 1070 machines as an example:

ETH:

GPU0 26.668 Mh/s - GPU0 t=82C fan=96%
GPU1 26.694 Mh/s - GPU1 t=74C fan=81%
GPU2 26.685 Mh/s - GPU2 t=69C fan=64%
GPU3 26.673 Mh/s - GPU3 t=82C fan=96%
GPU4 26.685 Mh/s - GPU4 t=81C fan=93%

All cards are within 0.03Mh or so......does that really look like a bunch of thermal throttling? I can post hundreds of other miner status lists showing the same thing.

Yeah those damn D3.... one of my group members invested in them, I had little say but helped found them a home and a long term solution. The D3s are currently running at PH and solo mode... we do get lucky every now and then....

I already have several nVidia rigs and they've pretty much always sucked compared to any AMD builds profit-wise.

I took loans for my initial farm - this is just a bit bigger loan. I'm not concerned at all.

  still holding 5200 of them

Oh well. Loan came back for $23,500 - way less than I was hoping.

Thinking I'm going to get another Vega rig and 4-6 RX 500 Rigs.

yeah you can mount it in a attic style configuration, but its 12 screws easy mount to cover a window space

Thanks Vapour and the others who replied.  Interestingly enough, my rig's config is almost identical to Vapours'... except that I am using risers and all 24 of my GPUs are MSI 470s... and the W10 version.  Mine shows as 10.0.16299... not sure how I tell which update was the last as with your 1709.

To answer some of your other questions...

- I have 2 Biostar TB85 and 2 ASRock H81 Pro BTC R2.0 Mobo's.  I have never touched the bios settings on any of these boards.

- All 24 GPU's were Bios modded using the strap-1500 method. After this W10 update and previous driver changes, I always used pixel patcher to get the cards recognized.  Also used the DDU driver cleaner prior to install.

All of these methods worked after any prior update to OS or Drivers but not this time. If it were just 1 or maybe 2 rigs with GPU 0 I too would thing risers gone bad. But like you said, in this case with all 4 doing the same thing, it statistically rules out hardware issues IMO.  I may go ahead and try swapping out 1 or 2 risers just for sanity sake first though, just because it's a lot less tediouos than messing with driver updates.  But alas, I suspect this will be an issue of finding the right set of AMD drivers that play nicely with the version of W10 on my rigs.

I have seen 18.3.4 mentioned a few times so may try that first.  Seems that was the last version before the 18,4.1 was released 3 days ago.

For my rooftop 10.7 kW system, installation was the biggest part of total cost ~$1.60/watt including racks and cabling. Here in California installer had to posses C10 and someone on the payroll with roofing license to install solar.

It probably still depends on the type of restaurant business. If you have a well managed restaurant it's pretty much smooth cruising and all you have to do is watch your people (gotta make sure nobody is slacking off and endagering customers with unsanitary food handling). I've found that well-placed CCTVs do the job well.

I think they are supposed to be more stable and let you try more video cards without having as many issues.
