I actually looked up the chip numbers, and its a “splitter”.

I, don’t know WHY there is a splitter, as a splitter isn’t needed, and these cards are advertised to only work on motherboards supporting bifurcation. However, there is indeed, a splitter.

The documentation is also, REALLY horribly translated.

Note: Without pcie splitter function in this host adapter (ASM1182E chip), so motherboard must support PCIe Bifurcation. Otherwise, only one M.2 PCIe SSD will be recognized. If you are not sure PCIe Bifurcation of your motherboard, please consult motherboard munufacture or contact us via amazon message

Here is the documentation for the chip itself: www.asmedia.com.tw/product/…/b7FyQBCxz2URbzg0

I, am not 100% certain how, where, or why it fits in there. Perhaps, its for link power management? Or something.

But, I can confirm, these cards DO require bifurcation to be enabled. Without bifurcation, you only see the first drive.

Wierd, but thanks for the info. The card i’ve used before pretty much only has 2 slots and a few random components on it l, like capacitors and such. So I assumed it was never needed. My motherboard didn’t support bifurcation, so I never got that to work though, so maybe it couldn’t work at all… only found that out after installing it.

  If your motherboard doesn’t support bifurcation, you can always use these cards: static.xtremeownage.com/…/r720xd-bifurcation/
  
  I have had good experiences with them.

    Oh yeah I fixed that issue already. Got a different card for it that uses a controllerchip. Its working great, without bifurcation requirement.
