Any help please?

Okay I have managed to get 3x cards running now.

The moment I plug anything into the PCI-E x4 slot, windows gives a blue screen of death error upon bootup and says "Machine Check Exemption".
I tried other cards going into that slot as well, and still the same error.

Currently the 3x cards are plugged into PCI-E1 (x16),PCI-E2(x1) and PCI-E3(x1)

Running PCI-Gen 1 and PCI Latency on 96 atm in the bios.

Is this a bad Mobo?

I will try the configuration again one by one.

Yes that is why I am so sad, figuring that 4x GPU's should be fairly simple to set up.

It is a G4560 Pentium CPU. Doubt that the cpu will have any effect on the GPU's being not detected by the M/B?

Thank you for the feedback Fury.

I have unfortunately already tried using both full length slots and two PCI-E x1 slots.
If I am not mistaken Windows 10 gave an error and did not want to boot up when I tried that configuration.

The part about slots being disabled as you have mentioned is not in my manual which came with the M/B. I went to check the online manual and there it was.

I will try the configurations again just now.

I cannot find any biostar or ASROCK bitcoin motherboard in my country

If I were to get the MSI Z270-A Pro will that work for my 4x GTX 1070?
I do not see any mention in the manual about slots being disabled with that M/B.

Response from MSI:
NVidia GPU's require at a minimum a PCIe x8 connection.
As you are wanting to only use a PCIe x1 connection, it is unsupported.


So what does this mean exactly? Which motherboards are compatible for Nvidia then?
This is where I bought my Motherboard:

Was thinking of Z270-A Pro ...?

Hi

Due to some hardware problems, I am only running 2x GTX1070 at the moment. Pretty much 25Mh/s each.
I am running the Ethereum and decra command together on Claymore mining.
When logging into suprnova I can see there are some Decra available in my account after a few hours.

For the ethereum I have set up a wallet on myetherwallet.com and used the following bat file:
EthDcrMiner64.exe -epool eu1.ethpool.org:3333 -ewal 0xc3fe071e91F54E66A35522f469Ed6a12B455c115 -epsw x -dpool stratum+tcp://dcr.suprnova.cc:3252 -dwal Almero.User1 -dpsw WorkingPass
The machine has run on and off for two days now while trying to figure out the hardware.
When logging into myetherwallet, I do not see that I have any ethereum available.


EthDcrMiner64.exe -epool eth-eu.dwarfpool.com:8008 -ewal 0xc3fe071e91F54E66A35522f469Ed6a12B455c115 -epsw x -dpool stratum+tcp://dcr.suprnova.cc:3252 -dwal Almero.User1 -dpsw WorkingPass
Then I changed from ethpool to dwarfpool. But still no ether is showing up in myetherwallet.

I don't want to run this for weeks on end and then it is just wasting electricity and I have set up something incorrectly. I do see "Share accepted" in the command line when mining ethereum.

Am I doing something wrong? Can someone please tell assist?

Ok I have unplugged all my graphics cards except 1.

If I put it in the PCI-E2 slot:
Bios Hardware Monitor displays that it is plugged into slot PCI-E2 Slot and PCI-E5 slot (Even though only one slot is used)

If I put it in the PCI-E3 slot:
Bios Hardware Monitor displays that it is plugged into slot PCI-E3 Slot and PCI-E6 slot (Even though only one slot is used)

Thus the Motherboard is somehow utilizing both slots when only one card is plugged in. That is clearly incorrect.
Any way to resolve this?

Hi

I am new to mining.
I have bought an 850W platinum PSU, MSI B250 M3 Gaming Motherboard ,SSD Drive, 1x4GB RAM and 4x Gigabyte GTX 1070 OC 8GB and 4x powered PCI risers

Installed Windows 10 64bit
Updated BIOS to latest version from website.
Installed all the drivers

In the Bios:
I have selected PEG to be 1x
Above 4G memory/Crypto mining = Enabled.

No matter what settings I change in the bios, windows only shows 2x GTX 1070 in the device manager.
Connecting GFX Card 1 and 2(with their own risers): Windows displays 2x GTX 1070
Connecting GFX Card 3 and 4(with their own risers): Windows displays 2x GTX 1070

Connecting GFX Card 1,2,3 and 4: Windows displays 2x GTX 1070

Thus the Gfx cards are working, it seems that the M/B is disabling some ports or windows is not displaying it.


I read somewhere about partioning the harddrive to GPT Boot sector. Don't know if that is required, I just did a basic install of windows 10 from USB and the setup
created the partitions.

Could anybody please help me so that windows can recognize all 4x GTX 1070 in the device manager?
