I have just installed a new distribution board for my workshop.

I have 63Amp/3-phase/240v to play with and I would like to have some form of metering so that I know I don't exceed 48amp per phase. My electrician told me that a simple "clamp meter" will do. He recommended me some China branded meter and I was thinking of a better solution...

Any recommendations? In amazon, I see many types from 20 bucks to hundreds of dollars for brands like Fluke etc.

Wish list... can the meter be displayed to an external LCD screen?

They have 3-phase power meters on the power buses in the labs where I work. I'll see if I can get some info off the meter modules.

Phil, you convinced me ! Now I'm just hesitating between the R9 480 and the GTX 1060. I'd like to get your thought on this, because I'll surely order soon.

Claymore said that he will release soon a CDM for Nvidia - so basically no difference

we can sell back to the grid a max of 67kwatts per hour on a good day. we have more excess to sell then that number.

Phil,

Just curious how much solar array costs, did state still allow you to cut $7.5k from taxes etc?

The array is buysolar' the miners are mine.

It is on his land he has panels on his home the barn and the horse pasture.

He has no miner risk as I supply miners.
I have no power risk as he provides the power.

We simply split the coins 50-50.

His business is solar installs .

We are running. 22 th as partners. He has some of his own miners. The array fully powers his home.

Since he is in the business he was able to make the install cheaper then most people can.

Think of the solar array as a bank cd ..

Put up 100,000 usd. Your interest would be free heating for the winter. And the coins you earn and of course a zero power bill.

With credits he believes the array will pay off in 5-7 year.
The solar gear should last for 25 years.

So it should do,well and is a long term investment.

OHM can show the CPU power draw for newer CPUs, similar to GPUz for the graphics.

yeah I will have to set it up just to break down what is cards and what is cpu's

If I shut off mining I drop from 584 to 50

So these cards pull 534 at the ac plug when I mine.

i only wished i had pushed my orders more.

speed fan is good as it shows all temps and allows me to change fan speed.

i want to build this same rig with 4 more rx 480's.

200 mh at 1168 watts sounds good to me
here is one more shot of temps

Yeah power companies vary a lot.

I have the solar deal with buysolar.

We are capped by the transformer of the power company at the moment.

May take 1 year to get them to give a bigger transformer

there is something that i discovered when i hang washed clothes to dry in this mining room..it felt cooler LOL, i have another idea that can improve cooling..

if there is a way to use this evaporative cooling pads like this and utilize some industrial quality aquarium pump to pump water 24/7 from a stainless steel tank to these pads inside a room..

evaporative cooling pads look like these..

http://img.diytrade.com/cdimg/917682/9089471/0/1242808014/greenhouse_evaporative_cooling_pad_wet_curtain_water_paper.jpg

I'm thinking evaporative cooling pads can absorb dust and can accumulate dirt, maybe you can use copper tubing turned several times to cover area in a room and pump water to these tubes from a stainless steel tank (placed in a cooler are of a house,like a basement)

these setup might cost less or equal to airconditioning units but surely cost less in electric consumption..

these are just ideas that might work, if fans are not enough anymore

Evaporative cooling is a LOT more efficient than conventional A/C in dry climates.
"Swamp Cooling" is old news.

Unfortunaltely, it relys on fairly low relative humidity levels to work at all, so there are large parts of the world it's worthless in at least part of the summertime.

Didn't see 90s here this past week, but did see mid-80s - and HUMID, rained almost every day. The machines prefer that but the human in the middle of some of them would have prefered the DRY 90s....

Makes me glad I sold off the S5/SP20 farm, but then again I wouldn't have enough electric available for my "ethereum-fuled expansion" if I had NOT sold that stuff off. I'm actively bumping up against "safe" limits on power draw at this point, even after I added the extra 50amp feed/box JUST for my "computer room" a few years back.

Just one reason I'm looking forward to the move I have planned for the next couple months - power limits are starting to become a real ISSUE where I'm at now.

from where i live, if a home is using a lot of power, you could request your own step down transformer from the power company (only if you are affecting the neighbors tapped to the same step down transformer).. or maybe you can request a new connection with watt meter (only if your line is maxed out but not the neighborhood step down transformer)

the m2 ssd sitting under those fornace may be at bad state with temp, can you check the temp of your storage?

I don't use an m.2, but I run OpenHardwareMonitor on my rig and it tracks all kinds of stats, including storage temp.

Lots of ways to get this value, just sharing mine.

http://openhardwaremonitor.org

I have speedfan. I will photo and post numbers I have been tweaking just a bit

now at 100mh and 580 watts

ssd reads 30c
and I am now at 100mh vs 96h

better shot of temps for ssd and for gpus

584 watts but watts flux from 579 to 592

For my XFX R9 390, with -100 mV undervoltage and ~1100/1200MHz, it will consume about 230W.

what MHs do you get from those settings?

For these frequencies, it will have about 31 MH/s each. For the 390, the hash rate is linearly to the Core frequency.

For my MSI R9-390 (non X)

-100mV/ 1050 / 1125

30.1MHs

Total rig consume 1310w (5 x 390)

Assuming cpu/mobo etc takes 150w

Each GPU consumes 232w

Looks like 390 and 390x, not real big difference in MHs/performance... except for pricing Shocked

Why do you need to buy the other CPU coolers? I use the Intel CPU cooler, they can cope with the heat.

some gen six don't come with a cooler.

Did you think about water cooling of GPUs?

Some DIY kits are way less expensive than complete systems

water cooling kits for many GPUs are expensive...water cooling the entire room is cheaper, besides it cools you too not just GPUs

Same thought here. I use the standard Intel CPU cooler and all is fine. Note that the ones for the i7 CPUs are better than the ones for the Celeron.
