Other Important Notes and Restrictions
•
For the memory modules to work properly, please install DIMM modules of the
same type, same speed and same operating frequency. Mixing of RDIMMs,
UDIMMs or LRDIMMs is not allowed. Do not install both ECC and non-ECC
memory modules on the same serverboard.
•
Using DDR4 DIMMs with different operating frequencies is not allowed. All
channels in a system will run at the lowest common frequency.
