or it is some proprietary slot and u dong get a connection
Why du u need that riser, when there is a whole pcie Slot aviable?
Do you mean "when there are two PCI Express x16 slots?"
Well, two of my PCI Express x16 slots are occupied by two cards atm. I do not need the riser now as I am going "in the future" to use the pcie x1 slot for a third card. I believe I cannot use the PCI slots with an adapter while my PCI Express x16 slots are occupied otherwise the risers block the fan inlet of the cards. Risers are tall from the looks of it.
Another work around is to get
two one PCI Express x16 extender for my
two one card, then I would be able to occupy the PCI slots with the work of 2 risers & 2 adapters.
