3 way furyx crossfire possible?

masterdeejay · Feb 19, 2022

I have 3 Fiji GPU-s in my rig. Two GPU on a Radeon Pro Duo and one on an Radeon Mi8 (R9 Nano bios modded but it is the same)
I have tried stock drivers, nimez modded drivers but there is no enable crossfire option on the Mi8 card.
They are same GPU, same clocks, same voltages, same memory size, pcie3 real 16x slot. The only difference is that the Mi8 is not a fury card but a nano so different VRM and cooling and it is working with games, bencmarks alone.
I know that CF is a dead thing but i only need it for experimenting, testing. For gaming i use an M40 card (TitanX)
So how can i force enable 3 way crossfire? Regedit?

I could be wrong, but due to my understanding of CrossfireX, you can only go up to 4 GPUs...... With the two Pro Duos, you are at 4 GPUs, so you will not be able to use the Nano as that would count as the 5th GPU.

I have only one pro duo that appears as two Fury series (nimez driver) or FuryX X2 (AMD stock driver) or Pro Duo (AMD stock Pro driver) in the device manager and i have one mi8 that appears as Nano or Fury series depending on the driver.

You can have more GPUs working, but it's not gonna be as Crossfire then.
Crossfire is no longer supported anyways.

It is working with 2 gpu-s, the benchmarks is better, and in games i see the crossfire logo.

Driver lock, so you'll need older drivers.
