Hi Phil - have you got the EVGA mobo yet - pls do review the spacing - seems that this mobo has better clearance compared to the Biostar. Thanks

BTW, I moved all my rigs to selling hash at Nicehash Equihash/ZCASH and Cryptonite/XMR market to fully leverage the nice rise of BTC now at 809$. Poloniex and Shapeshift is taking too much from me over time - rather cut off all of that and go to Nicehash and get paid directly in BTC. It may work out to be the same but at least I get BTC upfront.

i think if you could give more space between your cards you can run them all in summer, and with a good ventilation of course

take a look at my spider-man rigs..(there are others that are not spider-man below but they are fewer)

there is also a fan and cards at the other side, didn't fit in picture....it was a fan for exhaust to an open window.

i can install another rig or two just above the window because the air is cooler there (i opened a attic manhole just near it)

 Those should all work - but tend to be more expensive than the Biostar option.

 Personally, I'd prefer to find a good board with *3* PCI-E slots with proper spacing to leave an "open" space between each card, but all of the motherboard makers want to cram the 2'nd and 3'd card too close together (or want you to pay SERIOUS $$$ for a board with 5+ slots on it).

 Putting an ITX-type "short" card in the third slot on a common 3-slot board (or better yet, a low profile card) works well enough for good cooling. I keep wondering when Gigabyte (or someone) is going to introduce a "short" RX480 or RX470 board, they don't eat as much power as the Gigabyte ITX-type short 1070 board.

 If AMD can put a RX480 on a True Single Slot fairly short board (WX7100), someone should manage it easily on a "ITX-short" double-slot card.

Partly Windows IS that lame, partly limitation of the device drivers, partly that there are very few folks that run more than ONE card per machine so it is a very low priority for M$, AMD, or NVidia to bother trying to fix.

 Best way to flash the cards is do ONE AT A TIME - only one in the rig you are using to flash them with - that way you only have to worry about bricking one card at a time, and can verify that the flash for each card worked.

Well yeah, obviously I could pull that orphan Sapphire as you mention, but I would rather avoid that if possible for a couple of reasons.  Firstly, I had a hell of a time getting 5 GPUs working on this rig so aside from eventually trying to get a 6th working in that x16 slot, I'm not eager to start unplugging and re-plugging cards in case it screws things up again.

The other reason is this... I am even unsure how pulling that card would affect my device numbers? For instance, will windows re-number the GPUs after reboot only based on the now 4 that are plugged in?  meaning they would then be 0, 1, 2 & 3? 

Is windows really so lame that it doesn't have a utility or easy way to ID which GPU it assigned which device number?  It seems more likely that there is a way, I just can't figure it out.

Do you think these MBs can be used for 4 GPUs?

My issue in the summer is the base kwatt number goes from 12.7 to 17.7

great ventilation this - also easy to troubleshoot!

any feedback from your room mate or spouse?

The RX480's come in at about the same price here. You recon it's worth going that route instead of the 470's?

i am a big fan of the rx 470 by mis

well.. that's .. just.. creative  

You've got balls of steel for sure

1. About 20-25% each person back then. Now, depends on how much we earned and how much to put back in, when we reach a certain ROI on investment.

2. SRR - this is cheaper alternative than buying a switched PDU.

3. I think its up to you and your goals. Any business has risks - the trick is managing, adapting and overcoming risks. So it depends what you want to achieve and what can you afford (dont sell the house) etc.

4. 50 years and above... age is just a number.... so much still to explore and learn. BTC & the blockchain, FINTECH, etc -- so exciting, so why not be part of that future. Mining ASICS... there is only Bitmain and Canaan - yes unfortunately.... quality control is still unregulated in the world of mining vs standard IT HW like server, network, CPUs, GPUs etc..... But to be fair, HW like S9 while not exactly perfect is a quite a machine. Same for A7s - its latest but has its quirks.... $/TH ratio is not as great as S9, while Bitmain's RMA process is not exactly a picnic - expect 1 month or more turnaround time. I guess that's part of the "agony and excitement" if you're a miner -- otherwise Bitcointalk.org will be collecting digital dust.

5. One of the investor is in the security business so yeah... we have to be vigilant at all times - plenty of bad guys out there. Our farm is not big just a small farm but we do run it like a business. GPU farm uses a combination of several tools like... Claymore's Ethman and AwesomeMiner.com. Of recent, I am also testing SimpleMining Linux deployment to further simplify things but I think we can't escape from Windows that soon because of GPU driver support, miner's preferences, learning curve etc.

6. Standardized on G2-EVGA 1000, 1300 and 1600 PSUs. Heat will always be the miner's nightmare - 4 slots or 6 slots format - the problem is the same because it runs 24x7. Always, undervolt to avoid overheating with plenty of fan RPMs -- better replace GPU fan vs replace a burnt GPU -- that's the cardinal rule IMHO. Also, Claymore's temp controls are excellent, so I use alot of his control switches. The 4 slot Biostars are target temp at 77c and hard stop mining at 95c. My wooden chop stick trick below is perfect solution for the moment and keeps them at check at 77-80c

@phil

take a look at roof ventilation.



here is a video that shows how it works using smoke

note: there are also evap coolers that are installed in the roof.

preparing for summer early would be best..


P.S. good to know i wasn't the only one with messy rigs out here
