PCIE bifurcation single 16x to 8*8 with dual riser

My MSI b450m bazooka supports bifurcation from the 16x slot to 4x4x4x4 for their quad m.2 card
Would that mean it also has support for 8x8 bifurcation too on a different riser

I think I got one in my Dell server I can Chuck in to test


Make sure you get one with additional 12V power for the slots. If you drive 2 cards and both pull 75W from the single slot, you’re gonna break the power pins.

For my particular project I’m trying to get SLI working on a single slot with modded drivers (which is it’s own can of worms)

So the slots are too close together so I’m going to have to use an additional riser per bifurcation slot anyway I’m going to use a powered riser on each taking care of the double power requirements

Man this is the best there is for powered riser that has more than 1x bandwidth
Guess I can hotspot the cap in place for better durability
