I have a MSi P67A-GD65 mother board and 5 GTX 1070 GPU's. I'm able to attach and mine with 4 mother board but when I try to use all 5 I have problems. I have looked all over the internet and tried numerous things to solve the problem like:
- Plugging them in one by one
- Using PCI risers on all 5 cards
- Upgrading from windows 7 to 10
- Un-installing then re installing the driver
I just can't seem to get all 5 GPUs to work. Is it possible the mother board can't use 5 GPU's even though it has 2x 16x and 3x express PCi slots?
If anyone has any tips or ideas to get all 5 gpu's running I would be very grateful.
"I just can't seem to get all 5 GPUs to work" can you see the 5th VGA card in the Device manager ?
Because you did not tired this method yet , i would say , You likely need to short the PCI-E presence pins. It's all motherboard dependant .... you need to short pins A1 and B17 .
Also make sure you are disabling everything in the bios what you are not using on the motherboard , have a latest bios, have powered risers.
5xGTX1070 will pull
max 5x150w = 800Watts at the wall during mining process , without fine tune , + your motheroard/cpu/mem/fans maybe another 100Watts , so your system
max total will be around 900Watts. Make sure your PSU can handle that . With some basic tune you can get the 1070 power draw down to around 100 watts ...
