Memory Population Rules

Following these general memory configuration guidelines helps ensure optimal system performance — deviating from them may cause boot failures, unresponsiveness during memory configuration, or reduced available memory.

Memory Rules
  • Maximum 8 DIMMs per processor and 16 DIMMs in total.
  • Supports DDR5 registered DIMMs (RDIMMs) up to 4800 MT/s.
  • All DIMMs must be DDR5.
  • Memory mixing is not supported for different DIMM capacities.
DIMM Type DIMM Rank DIMM Capacity Single Processor Dual Processor
Min memory capacity Max memory capacity Min memory capacity Max memory capacity
RDIMM Single Rank 16 GB 16 GB 128 GB 32 GB 256 GB
Dual Rank 32 GB 32 GB 256 GB 64 GB 512 GB
64 GB 64 GB 512 GB 128 GB 1 TB
Expansion Slots

Six riser configurations are available, each with its own slot mix — some offering PCIe Gen5 slots, most offering Gen4. Configuration 1 stands out as the only one giving access to all three PCIe slots, while Configuration 4 is unique in supporting both rear drives and a PCIe slot. Note that not every configuration includes PCIe x16 slots.

  • 1 CPU Configuration: Up to 2 PCIe slots (1 x16 Gen4 + 1 x8 Gen5)
  • 2 CPU configuration: Up to 3 PCIe Gen4 slots (1 x16 Gen4 + 2 x8 Gen4) or up to 2 PCIe Gen5 slots (1 x16 Gen5 + 1 x8 Gen5)

Networking & Storage Adapters

Two networking options — the OCP Mezz 3.0 (running on x8 PCIe 4.0 lanes) and the LOM with 2x 1GB ports — can be used simultaneously, helping preserve the limited 3 PCIe slots on this 1U rack server. The OCP card supports up to 4 ports at speeds up to 25GbE.

Networking Options:
  • LOM: BCM5720 LAN controller with 2x 1GB ports
  • OCP Port Type: BT/SFP/SFP+/SFP28/SFP56
  • OCP Max Ports: 4
  • OCP Max Port Speed: 25GbE

Storage Controllers

This Gen16 Dell server supports both PERC 11 and PERC 12 cards, with fPERC installation recommended to preserve a PCIe slot for RAID control. Standard across Gen16 systems is boot device support via the BOSS-N1, which holds 2x M.2 SSD drives in its own dedicated riser and slot — capable of hosting either the boot OS or hypervisor. With 480GB or 960GB drive options available, storage capacity stays generous.
