I think u need at least 8gb of ram for this.. to optimise the speed of h/s you can do.. then a decent cpu too and probably Windows 10 would be perfect! Can get windows 10 keys for little as 4 pounds on eBay! Legal too! Plenty of 2nd hand motherboards u can find on eBay too maybe can get on for 30 pounds and also would recommend 120gb ssd but u can boot windows through an usb these days so that’s up to you but important you get 8gb of ram though! CPU u can get this one amazon as little as £35 for a second hand one https://www.amazon.co.uk/Intel-Pentium-Dual-Core-G4400-Processor/dp/B015VPX05A Also can get a cheap tower can be cheap to buy on amazon and ebay! Hope this helps and get you the cheapest way to mine these beautiful cards! And u won’t need a very powerful psu too! Cards automatically runs at 250ish..

If its a reference model, your level of risk is going to equal the reward of repasting / reseating the fans. Powercolor, in particular, is guilty of not always having molded dies, which sits a portion of the die lower than the rest--meaning you need MUCH more thermal paste, if you go that route.

​

If its a reference...you can go the Morpheus 2 mod route, and get a few static pressure fans to drastically drop the temps. That's gonna cost you, the aftermarket cooler/etc isn't cheap. https://www.amazon.com/RAIJINTEK-MORPHEUS-Superior-High-end-Cooler/dp/B071VZ7M4K

​

For thermal pads--IC Graphite is some of the best on the market, but its conductive, so you have to be SUPER careful how you cut it to make sure it fits perfectly. Works amazingly well though: https://www.amazon.com/Innovation-Cooling-Graphite-Thermal-Pad/dp/B07CKVW18G

​

With all of this--your level of investment / work is going to really equate to what you get out of it. These things are probably better geared to overclockers or gamers, but hell--the community recognizes it works really well for a reason.

Only a very small number of motherboard support 7, but here are a few options. One supports 7; the rest support 6. Make sure they are compatible with your CPU (it is easier to pick the motherboard before picking the CPU. Just get the cheapest CPU you can that fits in the motherboard for less than $50):

I'd want a good base on which to expand.

Celeron G3930 ~$40
4GB DDR4 ~$30
Asus B250 Mining Expert ~$150
2400W High Efficiency PSU ~$240 (this + 1xthis + delivery)
120GB SSD ~$60
Total $520

Now I'd have something to build on but I'd only have $480 for parts that do the mining calculations. So I guess I'd grab a Vega 56. Total is $1020 but that'll do. If I absolutely have to be under $1000 I can swap the SSD for a 32GB USB Key.

This would only give me ~1500H/s. But I'd have room to expand.

Of course that's what I'd do because I'd want to expand.

If you wanted a one off build then a few change em ups.

Celeron G3930 $40
4GB DDR4 $30
32GB USB $15
Biostar - TB250-BTC $75
Vega 56 $500
2 x RX 550 2GB $180
Corsair HX Platinum 750W $120
3 x PCI-E Risers $15
Total $975

That'd give you around 2,100H/s with a pretty efficient H/s/kWh ratio.

Cool. I think 1200 should be plenty. Just be safe when you decide to go to another coin. Don't want you to lose precious mining time and money due to a PSU working too hard.

Regarding the Biostar boards, and again from personal experience, they are the best boards I have used, period. I've used both of these boards, and compared to the TB85, they caused me more issues. My rigs would freeze randomly, knowing that every component was fine. When I would install/replace GPUs while using those Mobos I always had an issue of 1 or 2 cards not being seen, and I would have to swap which slots the risers were connected to, eventually getting the GPUs to be seen. I've never had that problem with the TB85. I just plug my GPUs in the order I want them in, and I'm good to go. But again, this is personal experiences, and I've seen people swear by those Mobos and how good they are, just didn't work well for me. All my rigs now run TB85 Mobos.

>Who pays 7.4 cents per KWh? lol you are a lucky dog brother!

​

The 7.4 cents per KWh plan I am on was a 24 month fixed rate plan I signed up for in June 2017 so I have seven more months on that plan. If I were to renew right now it would only increase to 8.7 cents per KWh. As for those who don't live in Texas, where we have deregulated our electric grid, and have to pay outrageous costs for electricity I do feel sorry. Maybe they should take their complaints to their local politicians and ask why they can't do what Texas does.

​

https://ourenergyllc.com/prodox/EFLS/oct18/ONC12FIXALLADVANTAGEPLUS-10252018-1.pdf

3500 KWh's: 3500 * $0.0854 + $5.99 = $304.89 take that and divide by 3500 you get 8.71 cents per KWh.

​

>Plus the rest of the rig is approx $500 more

​

What!!!. Who pays $500+ for a rig minus GPU's?

​

My Rig:

​

Mining Rack: $7.67

https://www.amazon.com/gp/product/B005KC6DY0/ref=od_aui_detailpages00?ie=UTF8&psc=1

Current price is $10.83 but I purchased four of these for $30.68

​

I have been winning these auctions for an average price of $23

​

4GB DDR4 single memory module: $25

​

Celeron G3930 with Heatsink/Fan: $33.50

​

250GB Hard Drive: $0

I got lots of free hard drives so this is zero cost

​

1200 watt HP Server power supply: $0

My Price is $0 because I bought a HP DL980 G7 with 768GB DDR3 memory for $644 and sold the memory for $1425 so the eight 1200 watt 94% Efficiency HP Server power supplies it came with are free to me.

If you had to purchase one on eBay the price would be $27.99

​

I recently purchased 41 used Risers for $60. That works out to $1.46 each or $5.85 for my four Vega 56 rig.

​

So total for the four vega rig is:

​

Mining Rack: $7.67

ASRock H110 PRO Motherboard: $23.28

4GB DDR4 single memory module: $25

Celeron G3930 with Heatsink/Fan: $33.50

250GB Hard Drive: $0

1200 watt HP Server power supply: $0

17x 6Pin Power Supply Breakout Board: $7.90

10x PCI-E Power Cable 6P to8P For Mining Breakout Board: $19.89

6Pin Input Pico PSU Output 180W: $19.50

4x Risers: $5.85

------------------------------------------------------------------

My Total Costs: $142.59

​

If you add a purchased 1200 watt HP Server power supply add $27.99 to get to $170.58 which is $330 cheaper than the Cadillac $500+ price you quote.

Re-post from original thread

A Monero ASIC would probably look a lot like option B.

Small, power efficient CPUs (low clock speeds), with independent access to 2MB of SRAM each. All talking on a shared interface to some kind of dispatcher assigning work.

I am thinking of something like this. That thing used 32 hashing chips. Each has their own mircocontroller to half-fake HTTP well enough to get work from a central server; living on the other side of the Ethernet interface.

I suspect a Monero equivalent would be larger though.

Edit: the mining blade is for 2xSHA-256 (like Bitcoin) only. It is obsolete. (my new hashers are like 8X as efficient for the same power use)
Edit2: option B appears to have lots of DRAM, not SRAM (2x512kB L2)

I had bad luck with this particular mobo and Vega, but saw success stories here... I would avoid it. My personal favorite is ASUS Mining Expert

And where is power cables for breakout board? The PSU is quite, but it's good for 5xVEGA only.
Read my comment about PSUs here

Awesome, thanks. What else do you have in your setup, I'm trying to decide on CPU etc. Currently looking at a cheap coffee lake motherboard with plenty of slots https://www.amazon.com/gp/product/B077Y5JBQ5/ref=ox_sc_act_title_8?smid=ATVPDKIKX0DER&psc=1 and a 300 series Celeron. It's been a while since I bought any kit and it will probably be a while till I do it again, so I want to make sure I can upgrade it, or use it for something else if the bottom drops out of the crypto market.

After getting the correct parts with a lot of research on which parts to get, Linux(Ubuntu) is running Eight GPU XMR Rig. I added the list so that you do not have to wonder which parts to get.

   How to get it working quick guide.
   
   ​
   
   Connect PCIE cable provided by Seasonic(You will use 4 cables providing 8x6 connections) to
   
   PCIE input ports.
   
   Since the mother board does not have 24 pin connector, you have to short 24 pin connector
   
   as shown in the following Seasonic self test video using the paper clip.
   
   If the 24 pin connector notch is on top, connect 4th pin on the first row with 3rd pin on the
   
   second row.

   Cover the paper clip with electrical tape.
   
   ​
   
   Once you get the pc booting, install according to my Vega mining guide with onboard GPU and single Vega and stop it at "ADD ALL THE VIDEO CARDS HERE". Turn off the computer.
   
   Connect remaining seven COMeap 6 pin connectors to PCIE output ports on the mother board and to other 7 GPUs.

A 550 4gb has good specs ok nice hash. Are they reliable?

What do you think of this motherboard: https://www.amazon.com/dp/B075KFPJ6M/ref=asc_df_B075KFPJ6M5420714?smid=A1FF9ODJZIUKGX&tag=hawk-future-20&linkCode=df0&creative=395129&creativeASIN=B075KFPJ6M&ascsubtag=trd-1120091410-20

Also, those GPUs are not available for me on Fry's. The cheapest are sold out and the second cheapest is unavailable. The best price I could do on that card is $200ea. Still worth it?

Thanks everyone for your responses. Here is a dumb question. But.. I need to ask. The power supplies I am using are EVGA Supernova 1000 watt G2. It states they are rated for 100-240v. The L630 plug with PDU is 208v setup.

https://www.amazon.com/Tripp-Lite-Vertical-Rack-Mount-PDUV30HV/dp/B0012VN0I0/ref=as_li_ss_tl?ie=UTF8&qid=1516596882&sr=8-2&keywords=l630p+pdu&th=1&linkCode=sl1&tag=oskoin-20&linkId=1cb71ee8826c1d8f3973a81f0386eb15 This is the PDU I am looking at currently.

Will the Power supplies I have work fine with this setup being that it is 208v and not full 240? I think that answer is yes, but I want to make sure.

​

And also, not to add more separate posts, from what I understand, I would use a normal plug-in with surge protector for my items such as fan/portable a/c, and computer monitor right? The PDU is for the powersupply of the GPU rigs only.

That's what I thought too! They might not be the correct card though. Here is the link: https://www.bestbuy.com/site/xfx-amd-radeon-rx-550-4gb-gddr5-pci-express-3-0-graphics-card-black/5869600.p?ref=8575135&loc=49ec4b2ca0cd11e7a863e645f6083ee10INT&acampID=49ec4b2ca0cd11e7a863e645f6083ee10INT&skuId=5869600

This one is different then these: https://www.amazon.com/gp/product/B071QXB522/ref=as_li_tl?ie=UTF8&tag=ccfreak-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B071QXB522&linkId=57a60614d19e66e2e19c300a05331be7

Do you know if they have the same hash power?
Thanks again!

I just setup my rig (5 x RX480 8gb) with these: https://www.amazon.com/gp/product/B01CU1U2XG/

Just plug and play and they work without a hitch. Let me know if you have any questions.
