Building the rig tonight
-
So- I got lucky, my boss doesn’t care if I run a miner 24/7 on his power and his internet, as long as it’s in my office, and doesn’t trip a breaker. and I’ve kept up with the cryptocurrency world reading all the white papers as they were released. I may do hvac for a living, but I don’t always want to be.
So after a week’s worth of research, some trial and error, I’ve ordered all the parts- and assembly starts tonight at 5pm EST.
Parts that I have on hand:
Old gaming computer:
1- M4A79XTD EVO motherboard w/ overclocking support for CPU
1- Quad core AMD 965 processor which I use to O/C to 4.2mg/hz while simultaneously playing a few games (so I know it’s solid even if it’s many years old)
1- HD Radeon 5670 1gb vid card (it was top of the line when built in 2010ish)
1- 32GB DDR3 RAM
1- 650W PSU
1- 64 GB SSD (windows 7 booted to it)
1 - 250 GB HDD
1- 500 GB HDD set up as a shadow copy of the other two drives for redundancy (and storage)
1- PCI WIFI card (I know I have to lose it to make space for the GPU’s)
1- sata cabled blue ray player driveWhat came from bestbuy today (cash poor, bestbuy credit 12 mos no interest)
1- 750w PSU modular corsair
1- 850w PSU modular corsair
1- 1500VA 900W UPS (I don’t want to lose everything due to shitty voltage- this is an old town)
3 - R9- 380X MSI vid cards
6- PCIE riser cables
1- amazon 46q egg crate
1- double power supply hook-up card
1- el cheapo insignia LED tv to run as a temp monitorOn order:
4- 700 kh/s avg scypt mining asic USB’s (most likely for world coin as my pool hash rate is only a paltry 4mh/s)
1- usb power supply for said miners
8 - DVI port 75ohm resistors
3- R9 380x
1- R9 Fury x
1 - intel I3 6100 processor
1- MSI Z170A motherboard
1 - 120GB SSD
1- pro edition windows 7All together:
2 motherboards
8 cards ( 6- R9 380x, 1 R9 Fury, 1x sapphire 5670)
650 w, 750w, 850w modular PSU’s
2 SSD
2 HDD
1 UPS (can only support 1 rig)
1 old tower case (with 1 side removed)
1 egg crateMy current computer that I use for work- I’ve only been able to successfully run minerd as a CPU miner (@ a very lowly 5- 10kh/s) , and have been unsuccessful with multi-miner, NSG miner or anything else. Well I take that back, multi miner says my onboard GPU is hashing and nothing shows up in my pool act, 10 minutes of hashing away with no restart, and I have no idea who got my 100 kh/s for my shitty little card.
I plan on mining worldcoin with the asics (I know it isn’t worth much, but maybe one of these days) and the rest is set to feathercoin or possibly eth.
pictures will be posted later, for right now- how the heck do I make multiminer work or is my laptop to crappy eg will it work on my tower rig?
Do I need the resistors to fake out the memory cards to get this sucker running tonight?
Is there a problem mixing and matching the cards? (will the R9 fury work with the 5670) does it hurt your hash rate or do they actually stack together efficiently?
Do you have any comments or suggestions based off my rig specs (IE try to get 6 cards on 1 instead of 4 cards each on 2)
Wish me some luck and hope that I can get the 4mh/s I am trying to get up to.
-
If you are going windows 7 I wouldn’t bother using more than 4 GPUs per rig… linux is a different story.
I have not seen anyone need DVI dummy plugs in a long time, you shouldn’t either.
The only thing with mixing and matching is setting whichever one you want to be your primary GPU to drive the displays. Other than that they all will work fine on the same machine mining.
You only have 3 PSUs for 2 rigs and none of them have that much power… TBH I would put the 650 and 750 together on one rig and try to get 5-6 GPUs running on a linux box and leave the rest for your 850w PSU.
Power draw for the 380x are pretty high and you will probably need to undervolt them to get them all running on those power supplies. I dont known what the draw from the 5670 is, probably not great. The fury uses almost no power compared to the 380x, keep that in mind when balancing your power load. With proper undervolting you should be able to get all 8 of those running at around 1600-1800 watts which is the max for 1 15a circuit. Stock voltages would probably be around 2100-2400 watts from the wall so be careful with only 2150 watts of power from those 3 PSUs.
-
So I should upgrade to 2 850’s and 1 750?
-
that moment you haven’t looked at a graphics card that takes it’s own power source ever (the 5670 is powered off the board and uses 70-80W)
HOLY %^&$^%#$ that is a huge card- it’ll never fit.

I always shoot for some overhead on my power supplies, they can lose several % in efficiency if you run them near or over 100% of their rated power draw. When mining scrypt I used 2x 850s to power a 6 GPU rig that pulled close to 2000w from the wall and neither PSU had an issue running that much power more than rated, can you do it sure, would I do that again, nope.
The EVGA 1300g2 is not that much more than the 850w version and is my go 2 power supply for best bang per $… newegg has the price pretty high on the 1300w PSU, I managed to get most of my 1300g2s for $160 before the mining craze drove up prices on them.
-
Some terrible news. apparently whilst building my monstrosity with the cards external to the rig, I shorted something on the motherboard. No clue what. But it kinda ruined my night.
For whatever reason, I get no fan on the PSU , I did try swapping them to no avail. I tried the case power switch. nothing. Shorting the switch contacts with a paperclip. NADA. Just a green ominous light on the motherboard- staring into the depths of my soul, blaming me for it’s death.
sighs guess I’ll pick it up tomorrow with a fresh mother in hand.
-
Good luck ;)
-
Curious why you chose the 380x over 380. 14% more shaders for 26% higher cost (~$50 avg. looks like, $240ish vs $190ish on newegg). Planning to mod bios and undervolt? Will they do that much better than the 380’s?

CG miner:
cgminer --scrypt -o s1.theblocksfactory.com:3335 -O lothar_hayner.gpu:x --thread-concurrency 8192 -g 1 -w 256 -I 18Doesn’t work at all
bfg miner:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
bfgminer --scrypt -o s1.theblocksfactory.com:3335 -u lothar_hayner.gpu -p x --no-submit-stale --shaders=400 --intensity=14Doesn’t recognize any devices attached
NSG miner:
nsgminer.exe --neoscrypt -g 1 -w 128 -I 16 -o stratum+tcp://s1.theblocksfactory.com:3333 -O lothar_hayner.gpu:xWill work at 6.2 kh/s on the 5670, doesn’t see the second card and when I add g2 and the parameters it does nothing at all
sg miner:
I haven’t figured it out in the least to make it work, or a startup script on the internetRight now I literally wished that I had slammed my dick in a door instead of buying 3.5K on good equipment that I can’t get to work
I can still return the majority of it, but I refuse- I will make this work- after all in under a year based on other people’s hashing rates, I should hit ROI in about 200-300 days
So here’s what has happend:
I’ve slept about 4-6 hours in the last 3 days
I’ve killed 2 cans of skoal extra rich blend long cut, and 2 bottles of wine - I’m out of beer, and the wine membership just came in
I’ve had all the marvel movies going in the background to keep me company as my wife is back home in the midwest with a very ill father, and my job won’t let me take off to join her.Motherboard was not bad, I was blind.
the original windows 7 after 6 years was corrupted
I bought a new SSD and USB
loaded ubuntu 16.04 (never used it) I loved it - but doesn’t carry driver support
killed it.
Downloaded 4 seperate copies of ubuntu 14.04 all of them in various states of not working, not able to update, missing libraries, which yes I tried to download and was screwed on
Finally last night, said F- this, bought a copy of windows 7 digital with downloadGot windows 7 going on this lovely beast
I have a
sapphire 5670 with 1gb DDR3
MSI r9 380 (not 380x)
4- future bit moon lander scypt asic usb (which show up on com ports, and I can’t figure out how to get those running either)
amd catalyst
MSI afterburner tool
amd sdk open CL
nsg miner
cg miner
sg minerNothing works except the sapphire on NSG miner at a pitiful hash rate no matter what I set the intesity to.
What am I doing wrong?
What am I missing?
I’d really like to get this rig going and then make a full step by step tutorial for anyone who is trying to start a mining rig in 2016please help. I am going for a quick nap before I keep at this for another day straight.
Note: I have read more articles than I care to, i have read pretty much every tutorial and programming guide, I’ve watched all the youtubes.
What in the mother-f-er do I need to do to get the 380 recongnized by NSGminer (when I put in a command for the second gpu, none of them work)
Anybody got any suggestions on how to get the driver set up on those future bit moonlanders and working with cgminer so I can mine some world coin?send help- I’m approaching 20+ working hours just on software and programming issues.sdk has been uninstalled and reinstalled probably 10x now. what more do I need to do? what did I miss?
-
hell at this point I’m willing to let someone putty in to help me get this shit straight and donate 2 weeks worth of hashing to them
-
Add me on Skype, gonna give you my MinerX, lets see if anything works for you with that tool.
Skype: ChekaZ80

still not fixed yet, Cheka Z is good though, built a nice little gui interface off the existing miner framework.
Still not fixed yet

What does “nsgminer -n” show?
HD5670 should be able of ~40KH/s. You want it for desktop use at low intensity (-I 10 to 12) while keeping other cards at their maximal intensities.
-
lies and slander - I did not install openCl just downloaded the file and ran an installer- have to compile it and all that jazz… sighs
-
Okay- I got it. Well I have 1 card running. Somehow the 5670 lost it’s openCL info- but I’ve got the R9 380 dialed in at around 400 KH/s of neoscrypt and only running 65c or so temp wise.
Tomorrow Morning when I get to work I’ll try sticking another R9 card in there and letting it run, and upping the core clock. I forgot to unlock the OC until after I had miner running and didn’t want to restart.
Yes 400 KH/s at 980 core clock, 1450 men clock, Mv+ 12 power adjusted +2% using msi afterburner utility- that’s the highest posted I’ve seen for the card.
Latest catalyst drivers installed
Sdk 3.0 library
Intensity set to 18
I’ll load my specs into this post tomorrow when I’m not on mobile -
well the cards are in and both running a combined hashrate of about 650-750 kh/s it seems to vary cyclically I’ve got both pumped to 1350MHZ clock speed, mem clock to 1450, mV +10 and according to GPU-Z they are each only drawing around 100-150 watts UPS at the wall says the whole system is pulling 400-500 watts
they were running 70 C (top) and 79 C (bottom) but sticking a tower fan right at the rig - I’ve got them both sitting about 65-70C sounds like a mini-airplane in my office but I’ll take it- it is all working, and all right. Everything is good in the world once again. Now I just have to figure out what my reset time on the computer needs to be- need to adjust so that the whole thing auto-resets and turns back on every two hours. Right now I’m noticing driver corruption around the 3 hour mark.thanks for all the advice guys! you helped!

Interesting to read how you get on, neoscrypt was developed to “allow” more distributed mining (by using consumer scale components).
Although it’s still a complex job setting up mining, it’s quite satisfying when you get it all running. Don’t do what I did and get “cocky”, turn up the intensity too much and end up bricking your gpu! :)
I see Ghostlander did an update to NSGminer, making it more efficient.
