EWBF's CUDA Zcash miner

[lagur]

What motherboard that will work with 5-6 NVidia cards?

Mod if there's any are also welcome.

Thanks

You prefer to sacrifice the M.2 and use a standard SSD? I didn't do the math. I was aware you could use an adapter on the second M.2 with win10 but it didn't occur to me to use both of them.

I use USB keys.  I don't know why you would need an M2 ssd on a mining rig.  

I am saying that because the guys over at P.I.M.P. stopped using USB keys and recommand
using a SSD medium level as a minimum config. I am using M.2 SSD because they are twice as fast as
SATAs.

I have a mobo that I cant do more than4 GPUs, do you think I could use the M.2 to install a 5th GPU and use a standard SSD?

I guess your version of Linux (NvOC) is adapted to work with more GPUs.

It depends on what mobo and cpu you are using.  Some mobos and CPUs are best avoided or not used.

MSI 170A Gaming pro
1x--16x--1x--1x--8x--PCI--4x
Tried many configurations

Bios Gen1 selected
When I install a 5th GPU it detects it but get a !flag in DeviceManager.
So I was wondering if using a M.2 adapter would work in the sole M.2 on the board.

I don't have one of those: did you try the changes suggested in this guide?  http://1stminingrig.com/msi-z170a-gaming-pro-carbon-motherboard-review-mining-performance/

Hello, can somebody save me from experimentation, is there any limitation regarding the number of GPUs per system with this miner? can i build a 9 gpu mining rig with 9 gtx 1060?  

9 GPUs at windows 10


https://www.youtube.com/watch?v=LDN2vkGPRW4 

cheers!  

if you looked closely that guy is only mining with 8 gpu's on Asus prime 270-A mobo. I'd like to be able to get 9 going as well but heard windows cant support more than 8.

I did it to 9 GPUs on windows with the same hardware shown on the video, Claymore support only 8 GPU thats why you cant mine with 9, but windows handle 9 GPUs perfectly (last version of windows 10)

i was wondering if EWBF miner could support 9 Nvidia cards, to take advantage of all the GPUs supported by windows.

Congrats.
If I remember well I think he once said -that the miner can support many many GPUs. (in the hundreds). But it is now easy for you to test if it works or not. So let us know when you do.

Anyone here who mines with 1070s and 1060s?
Will a 750w be sufficient with 2x1070 and 2x 1060 mining rig?

One gtx 1070 use 150 W and one 1060 use 75 W. And i thing it ll sufficient.

If you reduce power 1070 to 120W x 2 = 240W
                              1060 to 75W x 2 = 150W
Eco CPU + mobo takes about 40W, so sum ~430W You should be ok with 750W, but it depens on PSU. Corsair 750W got 4 PCiexpress so it would be ok for sure.

It depends on how good your PSU is, and you have not supplied us with that information.
Most good 750W PSUs will provide at least 60A of power, so if you set powerlimit to 120 and 90, you should be ok.
You will have problem connecting them, though, since you have only 4 pcie cables.
Try connecting 1060s to separate molex cables through adapters.
My Corsair TX 850 is running six 1060s with PL set to 100W.

I have an evga 750w gold. And im planning to power limit using msi after burner at 80%

This thread if for EWBF miner not PSU discussion, but answering some replies about PSU.

No, it is NOT dependant of manufacturer of PSU if you can attach 4 GPUs to it or not.

It is dependant only on two things - firstly - does your PSU can produce required wattage for your system? As rule of thumb good way to look at it is that system itself will draw around 100w so rest is left solely for your GPUs, so you looking around 650W for GPUs. For 4 cards that's 162.5W per card. You could easy run slightly under-clocked GTX 1080 with that or GTX 1070 with maximum possible OC. So in your case you could even go with smaller PSU, but most PSU bellow 750 don't have more then 4 PCI-E power cables and that's your second limitations - number of cables.

Im running 8 GTX 1070 with 1000w PSU with ease and stable.

wow nice mining rig.

im only familliar with amd cards bios mod and oc etc.

how do you oc 1070's for mining? bump up the memory clock then lessen the core clock and target voltage?
or do i just bump up the memory clock?

I increase base clock and memory clock and decrease voltage. gtx 1070 with EWBF miner gets me 420-425sol/s and draws 115-117W per card.

hmmm i thought you cant decrease voltage in nvidia 10 series. what i do is just set the power target limit to 80%

That pretty much translates into decreasing voltage.

Thanks my  friend, 5th GPU is working now.

I have a plan to build zcash mining rig with 6x 1080Ti on same motherboard and 2 powersupplies (2x 1300w).  will it be stable for mining?
