Hello all,
first of, I'm new hereon the Forum, so sorry if that got asked and answered already but I couldn't find anything related to the Topic.
I got an ASRock Z77 Extreme6 Board and I wanted to use a "Dual M.2 PCIe 4.0/3.0 X8 Adapter" to run two (2) M.2 SSDs on it but the Board needs to support "PCI-E Bifurcation".

So my question is, is this possible on my Board or, if not on default, is there a Patch or BIOS Version/Update around that enables this Function on the Board?
(Or is it just not possible at all because the Board is to old and doesn't support Bifurcation at all?)

Thanks in advance and Greetings,
Uwe

Hallo Uwe,

Ich glaube nicht das Birfurcation unterstutzt wir, damit meint mann das mann ein x16 slot, mit 16 PCIE lanes, aufteilen kann in 2 mal 8 lanes, oder 4 mal 4 lanes, und das letzte braucht mann wenn mann 2 M2 karten in ein slot benutzen moechtte.
Oder benutze das tech support formular

Und checke auch deine spam folder
Es gibt ein Beta BIOS 2.90A, damit kann mann 1 NVME M.2 auf eine PCIE karte benutzen, ich denke nicht das 2 oder mehr, laufen wird

-------------
Kind Regards

Hallo und danke erst mal für die Antwort.

Ich habe das genannte BIOS (2.90A) bereits in Benutzung... und habe mittlerweile auch beide meine M.2 SSDs ans laufen bekommen, jeweils mit einer kleinen PCI-E Adapter-Karte (eine im PCI-E 4 Slot und die andere im PCI-E 5 Slot).
Funktioniert überraschenderweise ganz gut und bisher ohne Probleme.

hello, did you manage to get an answer to your question? I also use bios firmware 2.90 and a pci-express expansion card for 4 SSD M2, and unfortunately I see only 1 ssd out of 4. maybe I just didn't find the setting in the bios...

No sorry... and I ended up switching over to AMD and a new ASRock Board wit already 2 M.2 Slots on Board.
Sorry again that I can't help you...
