Notes:
Using DDR4 DIMMs with different operating frequencies is not allowed. Be sure to
use memory modules of the same type, same speed, same frequency on the same
motherboard. All channels in a system will run at the lowest common frequency.
Due to memory allocation to system devices, the amount of memory that remains
available for operational use will be reduced when 4 GB of RAM is used. The re-
duction in memory availability is disproportional. See the following table for details.

Adding PCIe Add-On Cards

The 1018R-WC0R can accommodate two full-height, full-length PCIe 3.0 x16 and
one low-profile, half-length PCIe 3.0 x8 add-on (expansion) cards installed to the
riser cards included in the system.
Installing an Add-on Card
1. Begin by removing the shield located by the riser card.
2. Fully seat the card into the riser, pushing down with your thumbs evenly on
both sides of the card.
3. Finish by using a screw to secure the top of the card shield to the chassis.
The PCIe slot shields protect the serverboard and its components from EMI
and aid in proper ventilation, so make sure there is always a shield covering
each unused slot.
