Topic: Connecting 5 GPU's to motherbord problems (Read 735 times)
You need to short the pins as described earlier. Or if you can see the code 43 error in the device manager, you need to use the 7 GPU mod by lbr.
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 ...

make flash usb (16GB), boot, and check:
If you will see 5x 1070 cards - you have problem with Windows (so don't use it
)
If you will see 4x 1070 cards - go into a BIOS and play with it
