Message Sedonia, she can probably tell you what board that is.  How much is Mining Cave selling the case/mobo unit for?  I didn't see any listing for just the case/mobo....

I know a lot of you guys are into the riserless mobo setups, mining cave is coming out with a new rig kit (gpu mining rig w/o gpus, along with premade rigs) with a nice box around this setup, I tore one down in todays video if you're interested -- looks like a colorful board? anyone know the model number?

I have had clients that ran huge grow ops in Bell Air and would run 10 gauge extension cords throughout - I think the lights only pulled like 1200 watts or something each.

I did a couple tours through some of these mansions and I still can't believe or understand how they would get away with gutting these multi million dollar homes. Rent was 25k-30k on some of these homes and they didn't even hire an electrician to wire things...  people amaze me.

Long story short, heavy duty extension cords do work. Probably not the smartest thing to do, but I had these clients for about 8 years doing their financials and they didn't burn down a single house. Luckily.

 Should be able to run *5* rigs if they are only pulling 1050 watts each.

 Extension cords to run a miner = VERY BAD idea, even the heavy-duty ones tend to heat up a lot at the connections.

OK, thanks!

no, mine fired up as soon as i powered up the psu. and it was set to power on after power failure by default in the bios from the factory. even a bios reset results in it powering up with the psu.

Wow I can't believe how quick that was - I just decided to list 10 1080 Ti's  on OfferUp last night just to test the site out - had 15 offers and some dude is on his way over that supposedly wants them all.

I'm going to have to say considering these have been mining for a year this isn't bad at all.

So the first/initial boot requires a short?

once you get the board powered up, use the setting in the bios to autoboot when power is connected.. you should never need to worry about shorting again.

For you guys running the ONDA D8P boards, did you need a "power button" to start the board?  (e.g. short pins to power up)....

Here's a link for the fan we installed. It's a nice unit since it does not have to be hard wired like many commercial grade exhaust fans. It's not very loud on Low speed, so it might be ok in a garage if you don't have neighbors close by. We live in the country so noise has not been something we have had to consider so far.

*it is rated at 1950 cfm on high.

Very well clarified, so you saying I can run 4 rigs if I pull 1320W from the wall, I truly was hoping to run 4 rigs off this one dryer outlet, so I can have run for expansion cos I see my incinerator runs on a 20Amps breaker but only rated for 5.6Amps, thinking of running an extension cord from the other outlet its plugged into.

Each rig running right now pulls 1050 and 980 respectively, still plan on dropping down the power draw on the 1050 one, letting it run because it gives me 204mh/s with 1150/2020 core/mem with 1500 straps and top at 110W, will revisit the rig and see if I can trade 10W on each card that's 70W for 1mh/s, 7 total, will bring the rig down to 197.

Though, I am not very familiar with the RX 470 but I know they run 30W less than the 570's in terms of power consumption. I checked your ethermine.org stats, I'm so impressed by the what I see with the results you get with 1050/1800 mod. Your average and current effective are way higher than your reported hashrate, which is affected by the amount of shares you've submitted.

With my two rigs, 390mh/s it's been opposite of that, shares definitely lower than yours and average and current effective are never even close to what I'm reporting https://ethermine.org/miners/f8339952A224A228F2f8C58A5666a8Ff1EDdeBFb Was thinking of trying Nanopool sooner for a week as well to see if there's a difference, not after I ping both US servers at ethermine again. Connected to the US2, which is for the west, I'm in Texas and I don't know if it should be the US1.

Ordered the 10-30P to 6-30R adapter that I'll be using to connect the PDU to the dryer outlet. For heat control, I plan on running a box fan on window to take the hot air out, as my rig rack is just in front of the window, going to be moving that forward a little to create ample space behind cos I almost had a bad ordeal with the rain last weekend, never happened before but good I decided to go check the rigs.

I use the Rosewill L4500 4u case for my rigs with a little modification with a 1200W EVGA PSU and the Delta 3500rpm 153cfm fans up front, some cards in the first rig go up to about 77 degree Fahrenheit and the second never surpasses 74, so I definitely need to work on moving air more.

 

Two thirty amp 240 circuits .

Each one leads 2 6l20r   Total of four receptacles .

I need to show a link for him


plug these  4 cables into the 4 receptacles

and get these

the bars handle 14 amps each

since 2 go to a pair of L20-r receptacles leading to the  single 30 amp circuit   you are pretty much able to derate the circuit.  to 28 amps  at absolute most reality is

you can attach 8 + 8 = 16 items  as long as they are under  24 x 240 =  5280 watts total.

do this twice and the 4 receptacles will allow for 8 + 8 = 16  and 8 + 8 = 16

with 5280 + 5280  =  10560 watts.   now that is about 40000 btu  so at least 2x 1600 cfm fans  to exhaust air

I'd consider running  two 20A  240v circuits to two 6L20R plugs and then use two metered 20V/240v PDUs to power your 8 rigs.  Your PSUs will be more efficient and run cooler using 240V.  The drawback is that you'll have to spend ~$250 total for the PDUs.

Thanks for the tip Elder, I was just looking at putting in some AC myself also, but may investigate the venting option instead.
Although, being in a house not a barn may limit my commercial grade exhaust fan options due to noise aha.

yes since I mine and I sell  coins.
 It is legally possible to push profit forward 1 year.

My 2016 dec ending inventory of gear was say 10000
My 2017 dec ending inventory of gear was say 60000

that 50000 gain is not taxable until I sell it.  So far this month I did 6000 in sales  which will be reported for my 2018 tax year.

I only can do this due to running a long time internet sales business on eBay

https://feedback.ebay.com/ws/eBayISAPI.dll?ViewFeedback2&userid=philipma1957

 and here on the forum. Of course I prefer forum sales  as I don't get scammer doing returns like eBay.

This is why I can sell the 1070ti hybrids at a slight markup  and not price gouge like mad.

I still have the 3 evga 1070 ti  hybrids for 600-650 each 3 left.

I am supposed to get a zotac mini 1070  which I promised to someone but amazon has yet to get it to me.

all in all I will sell a lot off  during Jan and Feb

 It depends on the PDU - a few are "continuous rated" in which case they will probably be listed as "24 amp", most are not in which case a 30 amp unit should be derated to that 24 amps.

 The drier circuit is ITSELF probably a 30 amp circuit, in which case you would have to derate to 24 amps continuous usage ANYWAY.

 If your rigs eat 1320 watts "at the wall" or less, you should be fine with 4 of them.
 If your voltage at the outlet is higher than 220 volts, you can go proportionally higher on the wattage per rig safely.

I ran 80 Amps from my garage and I only had those 2 suicide vents that are in there so that was my only venting. I used 1 8" inline fan they use for growing marijuana to vent out the furthest suicide vent and my racks were in front of the other.

Garage was hovering around 100-110 but cards stayed around 65-70c @ 60-65% tdp.  

First question: On a 30amp pdu with a 30amp breaker you need to keep everything within that 20-24 amps or 80%. Anything more youll have a high chance of overloading the breaker and pdu

Second question:  I am running 23 rx470 cards with 1500 strap mod on a 1050/1800 (core/memory) the cards run around 23-26 mhs mining ether at ethermine.org https://ethermine.org/miners/31C1C0Fec59CEB9cBe6ec474C31C1DC5B66555B6 with that i bring in around .05 ether per day. my monthly power bill for the cards runs in the 220-300$ range mostly depends on outside temps in florida

you can put 24-26 cards on a 30 amp breaker safely
now heat ill be an issue so make sure you have somewhere for the heat to go
its winter right now so its nice but summer is coming...
