@yun999 -- I'm curious about how you use the 4k PSU bundles with open rigs.  It seems one PSU would power 4 or more rigs (at 6 cards each).  So when you have to take one rig down, what do you do?  Disconnect the 9 power cables going to the cards and risers?  Or are you rigs set up so you do maintenance in place?  I have to move mine to replace a card.  Right now the ATX PSU goes with it, so to do maintenance all I have to do is disconnect the 120v AC and the network cable... and its a unit.

I am liking the 4k PSU bundle, just not sure how to deal with it.  Or maybe I should build a massive open rig with multiple motherboards and GPUs and treat it all as one unit. LOL!.

motherboard work well? and does it needs hdmi dummy for turning on? also does 6 RX 480 s work on it?

which PSU is better to use and is DPS-2000BB enough for full rig with 6 RX480 s and motherboard ?

sorry for simple questions i'm new in GPU mining and trying to find out everything before i order all of the stuff...

Thank you

ZCL at the moment. Once I have a good amount I will switch to ZEC unless Eth jumps up in value again.

@stoon !  amazing setup, what are you mining on the Furies ?

My little setup, like most always tinkering to make things better.

no risers & cords (but i'm sure still some are needed to power the board right) will be great but still need to purchase a magical board to fit all 16 gpus in right ? as you mentioned it's cheaper compared to risers, this is really interesting then ! i hope its not too big (enough spacing for cooling) or too small (not enough space for cooling) but i'm sure you have done your homework & tests.

just a quick question that just came thru my head, on a regular setup, if a riser fails we can just replace with a riser & that should solve the problem, what if 1 of the slots out of 16 on the board fails, will it affect others ?

let's see how it all turns out when you decide to release it to the public in terms of practicability, costs, shipping and so on.

i hope it all goes well & if it fits in well for me, i will definitely be ordering a piece to play with or probably try to work with you to be 1 of your reseller/dealer/distributor/partner at this part of the world if you wish too.

i hope there's enough copper (i think minimum would be 2oz & up) on the pcb, 16 of rx's does really suck up quite a bit of juice.

show us some pix of it, a little preview.

much thx for the great work & share especially with this 1 of a kind setup. good work do keep up the great job ! 

I for one disagree. If the cost of setting up a 16 card system with his solution is lower than setting up two 6 and one 4 card systems like he his aiming for, I see absolutely no reason for price to be an issue.
Also I would LOVE to see a bundle that includes Finsky or Jabberwock's server PSU + nanoPSU + Cables bundled with this because this is the absolute best use case for the 2k PSU's and this is a complete quick deploy package.
Its not like you can just buy the board and run it without a power supply, and server PSU is the cheapest way to get it up and running so might as well buy them together.
In any case, bottom line is what everyone keeps saying "Quit Teasing and get Releasing"

picture tells a thousand words, well it might work well for me but may not for others & vice versa ... so far i'm happy with them. if it does not work well for me, i won't be getting over 200 of them ... GPU 0 & 1 are the GB G1's, GPU 2 is a nitro+ 480 8gb running 3 monitors with various stuffs running in the background.



how did i manage to get them to work at those speeds? like i said it's not difficult, just try with various settings just like any other gpus, maybe OP can share with his tests on the GB G1's that he has.

happy mining to all, back to work.

This is great and as a new miner I look forward to this, but I think all will be hesitant on price point.  At this point you can charge what you want, no competition, so if price is right and not higher than replacing your multi switching PCI board with multiple motherboards it will probably be worth it.  You could argue the price you spend on other gear like PSU's but that's already handled by Finsky. If you sell your board separate it will better than a full blown setup that is more than what most new miner's will pay for. Gotta quit teasing and release. 

Well the point of this project is to have a cheaper/easier entry into muti-gpu mining that never existed before. This will REDUCE downtime/cost and increase ease of setup, since no risers = no USB cords or riser power cords. Sucks I have to keep rebooting this dev system otherwise I could prob show off a 100+ hour continuous mining with no GPU fails with these boards. I don't even need to mention the benefits for a larger farm. 

Of course if a GPU does go down its just a matter of rebooting (about 2-3 min from reboot to full hashing with 16 GPUs, on eth, faster with Zcash or other algos)

yeah same , i had some of these sold them , you can get them stable but you have to lower mem by alot around 1825 max or so so they only get 26 mhs

also they are bad undervolters as well, i cant get them to 100mv undervolt , max is -65 undervolt , junk cards

ref 480 is still the best imo, or the saphire nitros at least  they run cool 

RX 480 G1 Gaming is crap in my opinion, have 15 of this and every card is hot as ****. Ref card is cooler. I burned by touching this card...

@yun9999 I believe that's the case since you have much more exp in 470/480/bios. And me being cautious new miner is enough to get decent hashrate increase with none or low try N error. Plus I don't have a test rig to play with fine tuning like Boysie does or fanatic craze to get the most hashrate juice possible. I am more for stability and longevity of the hardware. And one of the reasons for 480 8Gb was reselling value. But reading more and more, I am now thinking that 470 4Gb choice was better in terms of ROI. Especially with those cards with true 8Gb sold as 4Gb.

All my cards have samsung memory for good or for bad it is -,-

@yun9999 Do you run 'free' Claymore miner or have you purchased specially designed miner for your setups? From Claymore or another dev? Or maybe you have info into that, how much better/faster 'designed miners' are to 'the free ones'?

@Tasty Potato - I didn't word it well.  That's a general statement I always used not specifically to you.  I'm just saying if you're not an experienced BIOS modder meaning know how to use Hex Editor and all, then it's generally best to go with the 470 as they're very consistent and are easier to Mod BIOS w just the basics.  RX480 are a pain even for experience folks.  The fact that all the cards can be shipped with different memory type adds to this challenge.

Hmmm, why would you think I got issues with modding bios, I wonder 

It is a pretty straight forward process. With my all 5 RX 480 I am getting 150+ straight. Still tuning Msi AB and considering starting with only 21Mh/s -,-

I gonna ROI in 2~3 months if all goes above 40~45 bucks for Eth. Please hold your horses, all ya big Farmers out there 

Oh quit teasing already man, I've had a boner for 8 days now


Thanks man, but out of stock before I could get em did you buy them all again?


No I bought one for $26, took forever to get to me, but it works with my H81 Pro BTC V2. Did you change PCIe to Gen1? I don't think I needed to change anything else to get it to work.
I'm actually building a 4U case that I would sell with risers/splitter motherboard/cpu/ram/ssd/PSU mounted/fixed, everything except the cards, so I wanted to be sure if I should make it a 6 or a 7 card design. The Asrock H81 increases cost because of the headless display adapter so I wanted to go with the TB85 to keep costs low.
I will be mass producing these since there is a lot of demand in my country and noone knows where to get most of the components, and I have access to a laser cutting/machining shop.

yes longer warranty !

wait till those nitros jizz on ya LoL, not to be rude but just saying.

@OP, u mean something like this ?



yeah i like them too.

those 1500's are really hard to get them atm as they are very new in the market, rare & EXPENSIVE, so far i'm very happy with the 1 have now, will see how it goes, i'll slowly grab them when they're available in the market. my regular suppliers will keep them for me. i'll be testing dual 1200W plat on a 7 gpu rig using single c13 heh. really dont have much time but let's see how things goes.

I prefer nitros to the gigabytes although gigabyte has a longer warranty and better quaility

@ citronick - I'm envious of your Sexy warehouse.  Looks super Premium, as I can see fancy walls and even a Built in AC, not that you're using it, but definitely shows this aint a normal crappy warehouse.

@ jstefanop - Hurry and get me 1!!! MUAHAHAHAHA.   What parameters do you set so that 1 problematic GPU won't give the entire rig issues ( -w 1 -r 1) or do you skip watchdog to avoid too many restarts ?  I think the Windows claymore version is getting smarter at that vs before it would hang the entire system.  I'm sure there must be a similar setting for the Linux version.  I like it.  Keep up the good work.

@ yslyung - Very nice bro.  LOVING it.  Make them Platinum Server psu work hard.  Show them how PICO and Server PSU rocking it.   You got to do a multi RIG and take a picture of the LED glow from these GPU.  They're super SEXY after they start to mix up on colors.  I love them.  

@ deadsix - I have a splitter board, but it didn't work with my ASROCK H81.  Maybe I have a bad one?  They're not cheap so I'm not really sure if it's worth it to buy it just to have 1 more GPU slot and increase the odd of another piece failure and causing issue?  Are you able to get them for less than $25?

@ onefinecoin - I think the gaming and none gaming is not much of a difference other than OC.  We manually do that anyway so just buy whatever is cheaper.

@ tastypotato - If you're not good at modding ROMs, it's best to stay with RX470 as they're much more easy to get already mod ROM or you can simply copy Mem strap for consistent performance vs RX480 which is a mix bag and uses more power.   I have many different Non ref 480 and they are a pain.

@ Whyme - Just mem strap copy from 1500 to 2000 will get you easily 27MH with this card.  You just have to play with the Mem OC setting after to see what is most stable from 1850 to 1925.  The latter being the highest hash rate.


@ All - Please don't Quote the massive pictures too often as it makes it harder to follow and just add to more scrolling.  It will also add more work for me by editing later to delete and requote everyone by removing the multiple redundant pictures.  It's best to quote the person or response with @person.  Loving everything people are sharing.  AWESOME stuff, just trying to keep it streamline for new readers to follow and existing readers to be able to quickly find things.

30.1-3 mhs ETH - 437.x mhs DCR - GPUZ  80-85W

rest you will have to figure out but not that difficult. temps wise abt the same as the nitros.

oh yeah, the nitros does leaks sometimes overtime, some sort of transparent oil thingy.
