R650 riser configs

Hi, 

We recently acquired an R650 that had formerly had 2 CPUs installed plus risers 2 & 3.  Turns out if you go down to a single CPU, you can't use risers 2 & 3 anymore, since they both leverage CPU2.  I'm reading that the only valid riser config for a 1 CPU system is "R2A + R3A (Config0-1)"  according to https://www.dell.com/support/manuals/en-gh/poweredge-r650/per650_ism_pub/expansion-card-installation-guidelines?guid=guid-262db14c-7124-44d8-8d52-7f7bd86aa6ea&lang=en-us

But ... where do I actually find part numbers or a more robust description of what that means?

Ok I solved my issue.  Turns out there's a setting in iDRAC called "Hardware Configuration Validation" where you can just tell the system that yes, what you have installed is valid.  ???   "Accept current configuration as a valid configuration".  -> yes   

So, I did that and the errors went away.
