as much as i can see from their twitter feed
they are just running a maintenance and i think it will be fixed soon
not to worry much

All of my GPU rigs are mining on backup pools (mph, btg.suprnova, xmr.nanopool) --- so thats ok.

But last my 24hours earnings may well be gone now... if truly this is a hack job ... I can only imagine how Nicehash recover from this disaster...

@ Marvell2 -- Rule #1 - always have backup pools.

I didnt have to do anything... seems NH servers just went offline - maybe deliberate from NH side, well kudos to them if they did this to prevent the bad guys from doing anymore damage.
My GPU farms just went to their normal backup pools at configured centrally at MRR.

oh boy..... I am shitting in my pants now.

So a couple of things.

For optimal performance, you want a Southern facing sloped roof with no trees or other obstructions that will cast a shadow on the panels.

A 60 cell panel like the ones I have are about 65" x 40".  I have 56 of them on my shop roof.  That building is 80' long by 36' deep so just under 3,000 sq. ft.  See pic below:



In order to accommodate 180 panels, you would need a building with a footprint of about 10,000 sq. ft. on a single level.  How large is your house?

To get another 120 on a mining shed roof, that "shed" would need to be at least twice as big as my shop building above.

300 panels @ 280W = 84,000W.  With my current 80 panel setup, I generate about 3,000 kWh a month in the summer.  With the additional 48 panels, which are at a better angle to the sun and 20W more efficient per panel, I should be able to get to around 5,600 kWh a month in the summer.

Here's a cool calculator to estimate production for your location:

Sources are coming out that NiceHash was indeed hacked and wallets are being emptied out.  I hope it is not true, but if you had a significant balance in your NiceHash wallet, be prepared for bad news.

If you're a DIY'er it's not that bad.  I did a 56 panel roof system by myself and had a helper to assist with digging the holes for my 3 ground based arrays.  On the ground mount arrays, having a helper assist with getting the upper rows of panels in place is a must, unless you have equipment to lift them up.  On my 1st ground mount array, I was able to install the upper rows by myself using a front end loader to raise the panels and function as a work platform at the same time.



If you have a farm, I'm assuming you have a tractor with a FEL and possibly an auger attachment for drilling the holes?  I found the electrical work pretty easy, but if you're doing Net Metering with the POCO, you need to submit an application to them and also get a permit from the county and they will need to inspect your work.

I'm testing this miner and its using more power than xmr-stack for only ~50h/s more.    Anyone else noticed the same?

I'm a big solar proponent myself.  My rigs currently consume about 10,000 watts 24/7.  My current solar arrays help offset power consumption cost.  Here's a graph from Sunday when it was nice and sunny:



Of course this being close to the darkest part of the year here in the Northern hemisphere (I'm in Virginia), we don't have that many daylight hours compared to the summer months.  Too bad the sun doesn't shine 24/7!  

I'm pretty close to bringing 2 additional solar arrays online.  Got all the panels installed Sunday along with all the micro-inverters.  Just need to pull wires for each of the 4 strings through the conduit in the ground back to the sub-panel and I'll be at 35 kW.

You definitely need to do the powerplay if you are concerned with powerdraw. Otherwise it mostly even does not matter what voltages you set manually.


You cant get much more than 1950 out of them. I havent seen a reliable way to up the SOC clock with out significantly increasing powerdraw.

You can get 2080h with 1400mhz core / 1199mhz SoC / 1199mhz HBM with a 30%/50w increase in powerdraw. With some mods the cards would crash instantly without core @ 950mv. On some it will work with <900mv settings but it still actually draws 950mv.

I found that the extra 130h @ 50w and much higher temps are not worth it for me.


I know RednoWs reg worked on some cards with high SoC and low voltage but on most cards it will not work and I cant figure out what makes it work on some and not others....


Maybe silicon lottery...

This is not a trivial problem either. Probably most people in this forum spend more time on a $2k order than you apparently have on your whole proposal.

For monero mining it does not matter. But if you ever want to do dual mining, liquid edition is a must. In my tests, dual mining throttles the card even at 4000rpm fans.

These settings work a little differently for me:
16,539.8 MH/S(RT)
HW 56 (first 30 min - Chain1 20 HW - Chain2 36 HW - Chain3 0 HW)
843 WATT

 Very nice - best I've seen anywhere in the US in the last decade was $1000 for a 3000 square foot "mostly warehouse with a small office space" setup I had in the Indianapolis area for a while, unless the place was HUGE (10,000+ feet).

 $500 for 1000 feet with water/sewer/garbage included where I'm at now though is good for this area, expecially with the "cooling vents/louvers" built into the building front-and-back of the space, the "gable-type exhaust fan" that was already installed in the space (but in a bad spot, it'll work better as another intake), and I'm on the end of the building with 2 A/C units mounted in the "side" wall (one I converted to additional "vent" area with prior landlord approval but in a way I can easily put it back the way it was when I move out).

 I suspect part of the reason it's as low as it is would be the ACTIVE railroad track (single-track BNSF main-line) the property backs up onto - but I grew up almost as close to a dual-track Penn Central line so the train noise is no big deal to me.

 A standard 192.168.x.x privatenet offers ballpark 64,000 usable addresses - I don't think even BITMAIN needs much more than that, though I'd guess they probably use a 10.x.x.x privatenet "just in case".
 For example, I run my A2 miners on the 192.168.2.x subnet, most of the rest of my machines on the 192.168.100.x subnet, I USED to run a bunch of machines on 192.168.10.x via 10Base2 coax, I USED to run my S5 farm (and the SP20) on the 192.168.5.x subnet, and I have a DHCP address space set up for "short term usage on new machines I've not had the chance to fully configure yet" on 192.168.254.x
 My mining farm area though is starting to subdivide - each 6-rig "rack/shelf" unit will have it's own 192.168.100.xx1 through .xx6 address set, moving probably to 192.168.0.xx0 range if I get big enough eventually - makes it easy when I look at remote monitoring to say "ok, that IP is down, it is located THERE".
 I already had that implimented on the previous shelving units, each "row" with it's own .xx# and the # being the rig IN the row from top to bottom.
 I'm SURE this is not a new idea, though I've not seen it in actual usage anywhere that I can remember.

 It's NOT a good idea to push 300+ watts through a "dual PCI-E" type cable in a lot of cases - check the gauge of the wiring first, some of them are only intended to handle the 225 "8-pin + 6-pin" that are attached to them with VERY LITTLE left over if at all.
 EVGA and Seasonic cables should be OK - EVGA uses fairly heavy duty wiring on it's VGA cables for the G2/P2/T2 series (and I think they carried the cables over to the G3 series) and Seasonic tends to "double up" on the wires on their dual-connector cables.

That's my personal office aka "man-cave"   - my wife "evicted" me and my toys 2 years ago... a blessing in disguise I must say, allowing me to hook up with a few more friends to go "big" in the mining operations. Thanks to Phil and many others, we grew the farm bigger each year. The GPU farms are near my house and the "golden goose" Asics farms are hosted in Cryptoboreas in Labrador, Canada.

... just one stairs up from my office is the 2nd GPU farm, 26 x open cage metal frames, 17 x 20" floor fans and (3+2=5) x heavy duty industrial fans blowing out through the windows on the mezzanine floor. After consulting my buddies in data centres, i manage to use those heavy duty industrial fans to re-direct heat upwards and out the windows naturally. Overall temps at 35-36c during the day, and 33-34c during the night. During extra-ordinary hot days, 37-38c, I need to turn on that orange tube air extractor to help reduce temps another 1-2c. I am near the Equator so there is no winter season here.

The warehouse, above the office and my work area, hosts about 30 rigs and the next door warehouse which I also lease, similar size, around 36 rigs (older GPU farm). Both warehouses are powered with 63A/3phase via a bulk power provider and two broadband fibre internet provider (both warehouse share each other's internet connection for redundancy).

After the consolidation exercise with riserless mobos with 6 & 8 slots and junking out the risers = total both farms should be at about 50 rigs thereabouts... saving me a bit more on the power bill due to Cryptonite mining and also less rigs to pay to smOS service. About a dozen rigs are on H1110 and Biostar 12, 13 slots mobo. All AMDs RX480,480 were ex-ETH workers - now all mining Cryptonite. All NVIDIAs GPUs does the Equihash work. Only 30% of the farm are NVIDIAs.

These farms slave out Cryptonite and Equihash hash at Nicehash marketplace paying combined about USD$600 daily. The RX cards have served me well during the good ole ETH days - glad that they are still useful for Cryptonite mining. I dont bother with mining pools and their dramas anymore, just get BTC upfront by selling hash at NH... and accumulate BTC easy peasy.

atikmdag-patcher is what I used.
Also be very paitent as the cpu on the onda d1800 is rediculously slow.
