Stated 4.0 but read on from the title. As i think the lister of the item is trying to hit search results. This is for Gen3 and as such it will ever not work, like in my situation, or you will have slower speeds.

J'ai une carte mATX pour construire mon DIY NAS. Je n'ai qu'un port PCIE x16 sur cette carte mère. - il y a un port X4 pour une carte intel 2 ports RJ45 10Gb/s - un port nvme transformé en port PCIE x4 pour une carte SFP+ 10Gb/s Pas besoin de carte graphique, donc j'aimerais utilisé ce port (16 lignes) pour autre chose. 1 carte HBA (4X4 ports SATA) pour les disques, c'est bien, mais c'est une carte x8 et n'est pas optimal pour du disque en miroir. 2 HBA seraient plus utiles, mais il faut 2 ports x8. Et ben voilà, cette carte est exactement fait pour ça : diviser x16 en x8 + x8. bien sûr, il faut activer la bifurcation dans le BIOS en fonction du résultat voulu : ici 2 fois x8. j'ai essayé le 4 fois X4, mais d'après mes lectures, certaine puces intel ne permettent que x8x4x4. Sur les photos, on voit (CPU watercoolé): - cable rizer pour brancher cette carte de bifurcation pcie - 2 carte HBA SAS sur cette carte de bifurcation - NAS boitier fermé à moins de 30° en vitesse de croisière.

Mine did not work. The PC would not boot with it plugged in. The SATA power port and PCI-E x16 Slots were very loose. I believe the soldering job was poor and losing contact. Wasted $45. I wouldn't recommend this product.

mine could not negotiate beyond gen 1, on one port. Other than that it seemed nicely built. However I returned it. Another style worked fine. I wanted this wider style but didn't try again. Bad luck?

Connector doesn't extend out enough to use with even just one GPU. You'd need THREE riser cables on top of this to even attempt to use it.
