a few pod and usb stick miners.

Philip,

What are you mining with the 1080Ti rig?  What is it earning/day right now?

it is about 4000-4200 sols  close to 1150 watts  it does 35-45 a day nicehash/zec

here is the 13 card 1060  it does  3000-3200 sols

It’s income tax time in America so it’s always a good time to sell anything

Just got a k35 v1.2 to test
Paid for it last week on Monday and it came today by DHL however it was only made on the 10th according to the PCB so hot off the press!
Running nvoc no worries off a USB, had to hdmi and keyboard to config the bios but it has pxe and some other interesting features like a watchdog, reboot on power failure and some RTC stuff.

How nice is the dps-1200 / all 6 pin setup

Fuck bios flashing.

Repeat  fuck bios flashing

one more time fuck bios flashing.




She also told me  10 people mentioned me  as referrals.

I'll bump  that big fuck you to bios flashing lol. I only did 1 rigs worth and it wasn't that difficult with the batch flasher but I still had a bit of anxiety doing it. Even if I brick a card I would just get a refund, but it's still a hassle and wasted time, to me time>$$$

And yeppers - I mentioned Philipma sent me - give me a deal! Kept swearing I was already getting the best deal though hahaha.

Lmfao... so how do you guys REALLY feel about bios flashing lol?  Certainly that extra step for AMD cards is a major PITA! but to be fair, I have not had any problems with flashing but 23 of my 24 AMD GPUs are the exact same model... MSI 470 4GB... and those happen to be very easy to flash and the strap method worked very well for me.  However, looking forward to future rigs, this would likely become a monster to try to manage because it will be nearly impossible to build a rig with all the same GPU model due to the shortages. Therefore, you're left with having to investigate many different bios flash methods which leads to more confusion, wasted time, and likelihood of bricking a GPU.  Right now I have 3 Vega 56 that I have committed to sell. But I also have 2 MSI 570's. School is still out on those... if I think i can get 4-5 more relatively quickly I may still build that rig as a dual miner. But, I am definitely selling those Vegas and will use that $ to buy more 1070ti's as soon as they hit the market.

Well... got some pretty good news from the electrician in regards to expanding my house's mining capacity...

Seems it will be easy and relatively cheap ($350) for them to drop 4 20-amp circuits from my breaker box to 4 new outlets directly below it.  This would give me a lot more flexibility with my current setup (rigs in 5 different rooms), as well as the ability to more easily expand to at least 7-8 rigs.  Each of those 20-amp circuits could take 2 of my current rigs since they only pull about 800W each, so would be well under the recommended max of 2000W per.  Then I would just need to plan out how to best distribute my newer 7-8 GPU rigs, but overall, this expansion will make things much easier to manage.

The only downside is that my garage has no natural ventilation and while I can run 1-2 rigs in there from Oct-April/May without it, I will need to come up with a solution for more than 2 and/or in the summer.  The electrician seemed to think it would be relatively easy to buy a portable A/C unit and hire someone to drill through my wall to vent it outside.  I was originally opposed to this idea but if it's pretty common and easy to do, I would of course consider it.  Any of you go this route with your setups?

search for Panto-Tech, they sell cards and such in bulk

I'm not really sure if this is my first post but I'm so sure this is one of the thread I've actually sat down to read through all of its post and I can't find the perfect word to qualify it, rather than say impressive and encouraging. This thread is all about managing farms both from big or small and the information shared in addition to help offered and suggestions given have really turned up more light in my head. And all I can say to OP...Philipma1957 is that you are awesome and have managed to put together a small community within an actual community for like minded individuals, to all others who have posted and shared valuable information and also gotten detailed responses as well to your questions, I will like to say Thank You as I have taken a lot away from this one thread than the whole internet itself, on mining and having a mining farm mentality.

Though, I don't use the Onda boards or Nvidia graphic cards, but it is on my list as the next 21 cards I'm going for. I want to have an equal competitive mining setup but since my startup budget was just 10k USD, I decided to go for the most cost efficient set up. I started putting funds into mining equipments last year, I did managed to get 21 RX570 4GB cards, 7 of which are the ASUS STRIX OC, which have been flawlessly running not until the latest drivers AMD 17.2.2 and recent versions of Claymore 10.3 and 10.4 had I had issues with it, looking at other mining programs, found PhoenixMiner but it seems it ain't stable yet on some cards or Mobo's but I'm going to give it a test run for a week, hopefully this weekend assuming it's stable and would last that long.

The other 14 RX570 cards are MSI Armor OC 4GB as well, I would encourage anyone who's looking towards buying AMD cards to move away from this guys, I read in this thread as well someone saying they aren't working as other brands of cards they have. It is so true, that the second 7 card rig is not running and every time I try to running it it constantly crashes, and the other rig is running but with error constantly popping up on 2 of the cards. This cards have been frustrating, trying to mine other ETHASH algo other than ETH crashed the rig and some of the card even in compute mode would not do more than 25MH/S, 187MH/S total for 7 RX570 4GB with 980Watts power draw from the wall, I know that's ridiculous by standards. This cards were bought in the batch released November/December and since they were a rushed batch to meet demands at well then, I'm afraid the batch coming out next to meet then recently higher demands would be rushed, but since I would be picking up Nvidia cards, I certainly hope for the best and no MSI, if I have no choice then it would be the GamingX and Titanium ones only.

Here are a few questions for the Vets in here, going to be using my dryer connection for RIGS, finally found a 10-30P to 6-30R Adapter other than on EVSE who after 48hours refunded and cancelled my order, you need to have bought an EVSE product before they'll sell you any other products including adapters.

First question is, what does the 20Amps derated mean to 30amps PDU's?
 I am looking to see if I can run 4 rigs on a 30amp PDU from my Dryer connection. I live in an apartment and I have no other of changing anything, so I'm sacrificing my washer and dryer, I can do laundromats.

Second question would be general, what advice would anyone give as to how I can keep my earnings at the 1/3 ratio in terms of cost of running to profits? What should I look for, what should I aim for and what strategy would be best to use when trying to achieve this.

FYI..my electricity cost $0.13/KwH and also this is what my full time job is now since I started late last year, my goal is to try and aim for Hodling 60% of my earnings and creating a portfolio in different cryptos I have faith in, because when regulations start to hit the crypto world not all of the cryptocurrencies would be here. So apart from Hodling 60%, they rest 40% I want to go back in cost of operation, expansion and my day to day runnings.

Any ideas and advice, reads and suggestions are very much welcomed. Good to have found this thread, would go look for others in the series.

An ac unit will just drive up your power bill - what you need for mining is to vent that hot air out, not try to cool it down with AC (which won't be able to keep up anyways if you get several rigs in there.  Install a commercial grade exhaust fan, think of what is used in greenhouses for example, and if possible have an open window or vent in a door etc on the other side of the room.

We have a room in our barn with 12 rigs in it and the above method works very well for us, even in the summer months.

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...

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.

 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.

Curious WHY the firesale, I have never been good at knowing when to sell, is it now?

It’s income tax time in America so it’s always a good time to sell anything

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

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.

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.

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

https://www.ebay.com/itm/8ft-Power-Cable-Cord-for-SERVER-IEC-C19-Plug-to-NEMA-L5-20P-Connector-20A-12AWG/222592107550?

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

its winter right now so its nice but summer is coming...

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.

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.

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.
