So I’m running a H81 Pro BTC motherboard with the following video cards:

NVidia GeForce GtX 1070 SC in the Pcie16 Slot
4 Nvidia GeForce gtx 1070 SC in the pcie1 slots with risers.

I am running four gpu perfectly fine, however when I plug in the 5th gpu I get this error below at the picture link. Please help!!!!

Error Code?
Did you change PCIe Link in Mobo Bios?
Why don't you connect all GPUs with a Riser?

Have you enabled 4G decoding in the bios?

How many watt Power supply are u using? u sure u got enough power?

[Ethan1221]

Error code 43, I’m using two power supplies with a splitter both connected to motherboard.
I’m not sure how to enable 4g decoding in the bios I can’t find the setting.

One power supply is 650, other is 750!



I’m going nuts why the 5th isn’t working?


Is it because of 4g decoding, maybe because I have a legacy bios?

I’m sure it’s not the riser!

Asrock h81 has no 4G encoding.

Uninstall driver with device manager if this does not help, try DDU in safe mode and reinstall drivers.

disable 4g
install windows 10 in uefi mode
install the blockchain driver
activate 4g decoding
