DELL 9th Generation Risers

By Dylan Kerling – Velocity Tech Solutions

Today, I’m going to do a quick blurb about the 9th generation Dell servers and using different style PCI risers.

When configuring a PowerEdge 1950 or PowerEdge 2950, there are two expansion risers in the machine.  They come standard with PCI-E slots on both risers (Fig. 1.)

However, while the PCI-E slots are standard, there are also PCI-X risers. (Fig. 2.) These are for if you have some older style expansion cards that you would like to run in your machine that use the older PCI-X style slot.  The issue arises when people have attempted to run both PCI-E and PCI-X risers at the same time.

When attempting to run both kinds of risers, one of a few things will happen.  The machine will either not post, will go through post and give a riser mismatch error or just not even try to turn on at all.  So, while it is nice to have the ability to run older style cards, you than obviously lose the ability to run newer expansion cards.  So, with all of that said, unless you absolutely have to run a specific older PCI-X card, PCI-X risers, while available, are not the best solution.  Otherwise, you are losing out on the ability to run newer and likely better cards as a result.
