This post is in response to this video:
So my Servermainboard (I use it as Desktop) seems to support the ASRock Quad M.2
At the moment i cant take the system down - however I’ll supply images of the AMIBCP BIOS editor.
My Mainboard is a Supermicro X10QBI currently with only one CPU populated (E7-4890v2)
I can change the lane allocation of every single PCIE slot on the board.
With that sad, I sadly cannot test those claims - I dont have a ASRock QUAD m.2 card nor do I have 4 M.2 Devices, I suppose I could buy four of those M.2 -> PCIE x4 adapters on ebay an run 4 GPUs/Addin-Cards
So it would most likely work, but if I cant loan a Quad m.2 from somebody it will be only a theory - I sadly cant spend the money to test this - I just a student and I have to buy 3 of those Memory boards to be able to finally run 4 CPU’s
Hope this post was informative, best regards
