Topic: New Mining Farm - 60x RX480 XFX 8GB GTR cards (Read 3177 times)

Hot as hell coming into summer, 30-35 degree days increasing, cards still only run at 60-65 degrees, room is hot though.

Currently have the door to the room open completely, will be installing roof vents to pull the hot air out of the room in the coming weeks.

How cold is it at your location and are you venting the room?  As your cooling looks a little under powered for brute forcing it with 60 gpus even with the 14 nm technology.

haha well helps them out as well space not being used and money in their pocket win/win

watching your video, and that's inspiring to me
anyway good power supply, but for me it's over budget 

thats very cheap rent whish i had a friend like that lol

Thanks man appreciate it will test it out and report back with Version 6! I've found over the last 3-4 versions, it actually performs better at lower settings per say, once you hit that sweet spot mine jumped a little which was 1120/890-900 core and 2000/890-900ish mem settings, even by dropping by 10mv it increased hash rate almost as if it was getting less power so the %'s of the card were having to perform at a higher rate, sounds weird but testing shows it made a difference.

Marvell1 - I haven't looked into exact costs here but electrician friends said it could cost $10-20k for a home upgrade for what I want to run here, I will be renting space from a friend for $100-200/month

Good work, successful.

@Ziljtv  Do you have to have phase 3 ? I'm personally upgrading my garage with a seperate 200amp service here with 240v outlets thats enough to do a bunch of rigs if i wanted
and it costs only $4000 usd, bascially a one time cost vs paying rent on a place with a one year lease and i can use the extra power for my woodworking workshop.  If youre using a friends location and its free good deal but for most paying say 2k each month for a space and being locked into a lease in a really volatile industry where profits could go to near zero at a moments notice is a no-go

Ok, cool, thx for the info!

Well, I have an Power Meter as well.

You should check this rom:


112 Sol @ v5, check out the timings or get in contact with him, maybe you can improve at 100 watts less per rig.

Using this stuff from local hardware store I found as the base, and cut up a few pieces of square pipe to make a cross bracket the cards sit on

Marvell1 - Very expensive here to upgrade house power to what's called 3 Phase, generally only available in industrial areas unless you pay big $$ for it, overpriced and would blow ROI way out the window.  I'll be setting up Phase 2 and 3 at a friends workshop, already has 3 phase power available (240 amp's available standard) which will house up to about 40+ rigs without interfering with their normal work duties).

Mzie - Cheers hopefully it's helping people along the way as well, not everyone has been mining for a long time so hoping to help people save time and less mistakes along the way.

Man, all i can say is that i'm inspired and congratulations for this set up. You can only go forward and upward. Everything looks proper, inplace and onpoint.

Why dont you just expand you power at your current location

What are you using for the rack? it looks awesome!

Coinpro - depending on tweak settings can get a whole 6 card rig to around 680ish at the wall up to around 850ish at the wall.

58 watts will not be at the wall that will be what is showing in GPU-Z which isn't at the wall.  Need a power meter to show wall power pulled, I'm using one which can change to watts/amps etc..

How much watts does it take per card or fully?

Someone posted his modded rom in the claymore thread for his 480 with around 58 watts optimized for best watt/sol ratio.

Haha thanks! Your house Should be fine man I only have an 80 amp feed into my house, 240v, these mining Zcash only use high 2's in the amps and ethereum they were 3.5-4ish

i think its a good tutorial for the new person that want to build their own mining rig, as i watched on your video, your explain is really good to understand and i can follow your explaining with easy. i wonder how much cost to build your mining rig because i see that you hardware is really new.

thank you for sharing us your video tutorial and i hope you can get your success with mining.

So I guess I'm planning to order both for testing dummies and ethOS as well. My farm is also about 30-40 minutes drive away if there is no traffic and blackouts are real pain in the ass. I was also thinking about getting PDU's. I have to test every detail and it needs huge amount of time. So far win7/10 are working great if there is no power outage, but you never know what will happen. I want them to be on and mining with minimal physical contact.

Two words.  Bad Ass.  Lol.  Nice setup.  Keep us updated.  I'm thinking of adding a few more rigs myself but my house is historic and is limited to a 100 Amp breaker.   I currently have 12 gpus but looking to add 12 more if the circuit will handle that.

Thanks guys to summarise, right now I'm mining Zcash with each RX480 pulling around 110H/s (miner hashrates on the PC itself spikes between 105-130ish) average showing on the mining pool, this is of a period over 24-48 hours, so it's stable and accurate.  It's generating me just over 10% per month ROI at these figures.

Here in Australia I am paying about 17 cents US per KW at current exchange rate (I use US cents as all coins mined earnings are in USD basically).  so this is around 10% ROI after electricity costs which is pretty sweet.  I am also a forex trader and at 5% a month which I am getting give or take per month, I can retire in 4-5 years, so these farms are another means of passive income when the markets are bad trading wise such as last week with the election.

mettalmag specifically - I've ordered 3 of these to test - http://www.ebay.com/itm/0ship-HDMI-EDID-DDC-Plug-Headless-Linux-Windows-Mac1920x1200-emulator-dummy-USA-/191567271934?hash=item2c9a4c97fe:g:bcgAAOSw~OdVb-7m

from what I can see they act as a dummy monitor plugged into the HDMI slot, meaning your PC will boot up fine on a power outage/power cycle, the biggest issue with the RX480's, can't tell other cards cause I only have these, but generally without a monitor plugged in, they will not boot past bios, almost like a safety thing.  I even tried just plugging a HDMI cable in not connected to a monitor, but it didn't work.  I am working on this because my Phase 2 and 3 (30-40 rigs each) will be remote to me, about 30 minutes drive away so I don't want to be driving out everytime there is a small issue haha.

I have my rigs set to power on/boot into windows 10, startup batch files to run my miner files and in the config files I have my voltages set for memory and core, this way even if they restart/shutdown and sometimes reset to "factory" settings, my bios mod is factory, they come back at 1000 mv's per card, but the first miner startup they are then set to correct mv settings again

I'll go into this more in future videos but something to think about.
