Hey Philipma, I seem to find you around the forum a lot, and it looks like you're very knowledgeable. Now, you say I can run 6 GPUs with 1600w, does that mean I can run 5 Fury GPUs with an Evga 1300w PSU safely?, again, I don't plan to do nothing crazy with them and with probably undervolt and the price difference between 1600w-1300w is important.

What's the 1+8 trick?. It also seems like you won't be able to claim the warranty because of the bios (you should try contacting Sapphire anyway), also probably why the previous owner sold it, the card was showing signs of a failing.

Btw, I'm running 7x RX 470 and 480 cards, and they've been awesome and stable. Just a little underclock and now all run below 68ºC.

Well, finally the laws of supply and demand made the choice for me, the TB85 could be had for $70 whereas the BTC PRO was $175 (damn scalpers!). The MSI Gaming 5 is nowhere to be found under $150 so it's out of question (some local offers at around $130 but no warranty whatsoever, and I'm currently on a budget). I was finally forced to give Biostar another chance, let's see how things go this time around.

Regarding those RX, set the core clocks to 1050, thank me tomorrow

Great responses, it seems like any of them will work just fine for me then, I guess it's like you said, whatever is available at the moment for less $$$.

Thank you all very much for taking some time to share your experiences. If anybody else wants to chime in you're welcome.

To the guy who is crashing in Windows without mining, your issue is with your risers, use ver003 or 006 risers, or get new ones.

If you will build just ONE miner and don't plan to build more, this is the configuration I would recommend, I will mention US prices since I buy there so you can have a base:

- MSI Z97 Gaming 5 Motherboard $130: A little expensive but will give you 7 PCIe slots (3 x16 + 4 x1), works great and has a led code display, great for troubleshooting.
- EVGA G2 1300w PSU $185: This modular behemoth will provide all the power you will need and then some, even the 1000w version will probably get the job done but it's always a good idea to have some headroom.
- 7x Sapphire Nitro RX 470 8gb GPUs $229 e/o: These little guys use have faster MEM so they will mine ETH and other algos just great, I own these and XFX RX 480 8gb and can barely notice any difference. Stay with the RX line GPUs if power consumption is a concern for you.
- 8gb DDR3 Crucial Ballistix RAM kit $35: Cheap, reliable RAM. 8gb will be more than enough to cover your RAM needs.
- Intel Celeron G1840 CPU $45: Cheap-functional CPU, will give you all the processing power you'll require on a budget.
- Samsung 850 250gb SSD $100: One of the best SSD brands, this one won't explode on you and will give you very fast boot times
- 7x + 7x USB risers (ver003 and/or ver006) $10e/o: Why 7x + 7x?, well, risers like to give trouble (compatibility usually) and having a miner not working because of this is a complete waste. Buy x7 from 2 different brands/sources, usually the x16 ports won't give you trouble with any risers, but if you find the miner is having trouble booting up, try the second set. You can even mix them, but try filling only the x16 slots with one brand and the x1 slots with the other.
- Used DVI-I Monitor/DVI-I cable: Check for any inexpensive monitor around that will accept DVI-I signal, you'll need that. The cable too if you don't have one lying around already.
- Ethernet cable/WiFi card: Whatever fits your connection needs best, the miner needs to be able to connect reliably to your net in order to work.
- Windows 10 OS: Definitely the best option to run 7 GPUs without issues.
- Chassis: If you can work with metal/aluminum, check the net for some interesting models. If your resources/skills/toolbox are limited, you could try a PVC build, easy and CHEAP. You could also buy a pre-built chassis for anything between $100-$250. I prefer using an open chassis for better cooling.

I hope this helps.

Hey everyone, I'm on the verge of building some additional miners (hopefully) and decided to do some research, hoping to gather from the experience of other builders, this time I have a selection Motherboards I've been checking out and wanted to see what do you guys think, and if there is any other one I should be checking out. I want the best reliability and an affordable price, in that order. This is what I've gathered so far:

Biostar: Have heard their hardware isn't the best from a very experienced builder (he has been inactive for some years now, things might have changed), and from my experience I currently have a client's H61 board that lasted 1 year of very light use and now just won't boot up (seems like a bios issue, no whines or heating or signs of a physical failure of any sort).

Asrock: Have used some of their hardware and the quality seems fine, my current PC has been working since 2012 with a 990FX Extreme 4 and it's now become a miner, no issues at all, power/reset buttons on the board, led code display, love this one. I Made my first miner with a H97 Anniversary and it worked just fine for several months after I sorted some riser compatibility issues, eventually changed the miner over to a MSI Z97 Gaming 5 to add a 7th GPU, and when I got the parts for a new build... The H97 board now seems to be dead (tried 2 of every possible part, PSU, mem, CPU, it's definitely the board), again, no physical signs, the bios was updated during the riser mess and worked fine, no idea what happened there. Regarding the BTC Pro, I've read both good and bad things of the 1st version, and have a couple friends running them with no issues so far.

MSI: I'll just share my info, the Z97 Gaming 5 is a rather expensive pick (mine was $130, if they can be had for $80 I'll surely jump on this one). This board is on another level compared to the rest I've mentioned so far except the Extreme 4, led code display, 7 PCIe slots, just throw Win 10 and you'll have 0 issues, no reg mods, no hassles. I've been running this one for a couple months already with 7 Polaris GPUs (470 and 480 mix) and I haven't had a single problem so far.

Bonus question: Which board would you recommend for 5 PCIe - 5 GPUs?

Good, that's what I wanted to read!.

Hello all, this is my first post around here, I'm a miner so most of my threads and answers will be regarding this side of the Altcoins (mining). Today I have a simple question for you: I have an EVGA 1600w PSU at hand, and I want to try some R9 Fury cards for mining, power cost is off the equation so it isn't a concern. So the real question here is: How many R9 Fury GPUs can I power with that GPU? I don't plan to overclock and might actually undervolt the setup. I'm thinking I might be able to power up to 5, just want to be sure I'm not stressing the PSU too much.
