@Badgerden , welcome to the forum.


Here is the Maintenance and Service Guide for the workstation.  This is what it shows for compatible processors:


Processor technology Intel Series C612 chipset:

Support for the Intel Xeon Processor E5-1600 Series and E5-2600 Series

Integrated 4-channel memory controller

Microarchitecture improvements

Large L3 cache for superior performance

Intel QuickPath Interconnect (QPI) connects processors and I/O controller with speeds up to 9.6 GT


This means that the Xeon processors are the only processors that have been fully tested to be compatible with the motherboard.  The i7-9700 was released in 2019 and requires a Series 300 motherboard.
