So with only one open card slot, I'm thinking I should buy the most powerful card I can for it being this as the best deal? 3 fans @ 700

as i said AT THE MOMENT OF WRITING , stongest card providing HIGHER HASH RATE (no matter the power consumption)  is RADEON PRO DUO ... 900 to 1100 hashes /s  depending on the oc you apply ... of course the higher the hash rates the more inefficient it is... at 900 hashes is a bit less efficient than nvidia cards (4.5 w for each hash)

Per that number the TI only uses 156 w per hash?

thanks for your reply. can you recommend me a mobo with 12 pcie slots for this case?

thanks in advance

PCIE connectors are the cables that plug into your video card, not the PCI-E slots on the motherboard. There isn't a 12 PCI-E slot motherboard on the market. Ones with 6 slots are rare enough, sometimes you will find one with 7 slots.

Was it a Motherboard with 6 PCI-E slots you needed or a Power Supply with 12 PCIE connectors? Or both?

 I've seen up to 16 PCI-E 16-bit slots on a motherboard, but it was a server-specific passive backplane style board and not real suitable to try to mine on AND bloody expen$$$$ive.

 
 It's entirely possible to run NVidia and AMD gpus in the same machine - but it tends to be less stable than a "pure" rig.
 Windows 7 or 10 does this easily, LINUX can do it but need a bit of custom work on installing the drivers.


 The Radeon Pro Dual is 2x Fury Nano on one physical card - can't clock it QUITE as high as a Nano due to the higher heat generation in less space, but can get pretty close per multiple reports.

From an owner of 5 Pro Duo's, here is a heads up of what you will face  :

Windows 10
The recommended mining driver 16.3.2     = Maximum 2 Cards, 3rd will BSOD.
The newer drivers which allow 3 cards     = Miner will mine at half speed.


Linux
simpleminingOS : after fiddling , got 3 cards running with no fan control or temps display what so ever, card were almost fried as there was no fan control. its resolved (sometimes) by using on-board vga and main display.
EthOS             : 3 cards will show but only 5 gpu's out of 6 will mine.


I asked Claymore and  EthOS Support, all agreed on one thing, this card have shitty drivers and they can't do anything from their side.

The 1080 Ti can be set to do ~600 sols at ~150-155 watts. About 3.9 hash per watt ratio. You can get it up around 700 sols or higher but it will use the full 250 watts and beyond, making it very inefficient if you run it that way.

I have 5x SAPPHIRE Vapor-X Radeon R9 280X DirectX 12 100363VX-3L 3GB 384-Bit GDDR5 PCI Express 3.0 CrossFireX Support TRI-X WITH BOOST (UEFI) Video Card

I want to add one more card to this rig, my understanding is that I should add an AMD card for best efficiency? I'm interested in adding a 1080 TI but I do not want to create a headache for myself. What's the recommended card at the highest performance that would run on this rig as the 6th card?

Is this card compatible with EWBF's CUDA Zcash miner?
Can you post a printscreen of this 900 to 1100 hashes please?

If you had the requisite 12 PCIE connectors on that PSU and you made sure to reduce the power limit on each GPU before you start to mine you might be ok. 150 watts per GPu is 900 watts, depending on the rest of your hardware you could have anywhere from 50-200 watts added onto that. When you take into account your PSU's efficiency rating you will be pulling anywhere from 1050 to 1220+ watts from the wall and you should never load your PSU to the 100% max... 80% is the most I like to do myself. You will burn out your hardware allot faster if you stress it too much. Wink

well i plan to build a 6x (or 7x gpu if possible - but i think its not with nvidia?) mining rig with gtx 1080 ti cards. if you can recommend me a motherboard, psu and cpu for it, it would be awesome.

thanks in advance

These motherboards go out of stock pretty quickly, so grab one now if you're sure you want to build a rig.

https://www.newegg.com/Product/Product.aspx?Item=N82E16813138436&cm_re=biostar_tb85-_-13-138-436-_-Product

If you want to do 6 GTX 1080 Ti with a single PSU you need this or something with the same specs and connectors.

https://www.newegg.com/Product/Product.aspx?Item=N82E16817438033&cm_re=evga_1600_watt-_-17-438-033-_-Product

Any socket 1150 Intel CPU will work for mining, even the cheapest Celeron. If you want to use the rig for office work, web browsing, streaming video/music while it mines then I suggest an i3 from that generation.

https://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=-1&IsNodeId=1&Description=lga%201150%20cpu&bop=And&Order=PRICE&PageSize=36



Would the (240v)2400w delta power supply from Paralellminer be a cheaper alternative to the 1600w EVGA for a 6 card 1080ti setup??

When having a rig that need huge amount of power, i have learned the hard way that is kind of better to go with 2 power supplies.
It's cheaper and when one goes bad you "limp" away with half a rig and still make money till you fix it instead of totally blacking out.
It's also usually cheaper in total price.
It's easy and 100% safe when done right (i use add2psu to connect 2)

Good luck.

Add2PSU is  just a relay to daisy chains the PSU's so they start at the same time. The same can be done by jump starting the PSU with a piece of thin metal between the green wire and a black wire on the slave PSU and then turning on the switch on the back before starting the computer.

https://forum.overclock3d.net/showpost.php?s=3c0b5ead1c29a7c47c0e8fceb274ecf8&p=3815&postcount=1

Or using an automotive relay:

http://www.jonnyguru.com/modules.php?name=NDArticles&op=Story&ndar_id=27

You could also connect the two green wires on the PSU's and they will both start at the same time as long as they share the same ground.

The bigger question is when using powered risers is it safer to have the cards powered by the second PSU to also power the riser on the card. Some with experience in the matter claim you should just connect the second PSU to the PCI-E  power connector on the card and have the first PSU power all the risers:

https://bitcointalk.org/index.php?topic=1761303.msg17827649#msg17827649

In researching, i've heards arguments for both without a definitive answer.

Just let you know it may be not that easy to get 6 cards working smoothly, there could be small issues here an there. I right now have 2X 1080TI FE + 1X 1070 on board, I could only start the miner first then EVGA OC software. If I do it the other way, miner will be freezing. In my case, I got 1080 ti up to 740 hashes before I cut its TDP limit to 80%, so definitely for a short while it eats up to 250W. Another stupid thing I could not explain is Nicehash is quite unstable with one of my rigs (I have two sets of 2X1080Ti+1X1070 on the same motherboards).

Better to find some one here with success then you exactly copy what they did (especially get the identical motherboard/OS)

that's a really good point . . these problems remind me of car problems . . massive headache! currently thinking of simply trying to add another SAPPHIRE Vapor-X Radeon R9 280X DirectX 12 100363VX-3L 3GB onto the rig that already has 5 of them and call it a day if I can get that running smoothly

It would definitely be cheaper as long as you have 240v to power it. $109 vs $330 for an EVGA 1600 watt PSU. YOu would still need another ATX PSU to power your risers, motherboard, CPU etc, but you can get one of those for $50-70.
