Built on 3rd Generation Intel® Xeon® Scalable processors, the Dell EMC PowerEdge R550 delivers added configuration flexibility for organizations prioritizing exceptional value.
The PowerEdge R550 supports up to 16 DIMMs, reaching up to 1TB of total memory at speeds up to 3200 MT/s. It uses registered DIMMs (RDIMMs), which reduce memory loading via a buffer and enable greater density for maximum platform memory capacity.
| Capacity | DIMM Type | Config | DRAM | DIMM Max Speed | Rated Voltage |
|---|---|---|---|---|---|
| 8GB | RDIMM | 1R x 8 | 8GB | 3200 MT/s | 1.2 V |
| 16GB | RDIMM | 2R x8 | 8 GB | 3200 MT/s | 1.2 V |
| 32GB | RDIMM | 2R x8 | 16GB | 3200 MT/s | 1.2 V |
| 64GB | RDIMM | 2R x4 | 16 GB | 3200 MT/s | 1.2 V |
The Dell PowerEdge R550 rack server supports PCIe cards that plug directly into the system board, with no riser card support in this configuration. Check the PCI table below to find the right slot for the adapter you're installing.
See the manuals for details on slot priority and the types of adapters and expanders supported.

The Dell PowerEdge R550 includes an embedded LOM board with 2x 1Gb ports via a BCM5720 LAN controller, plus the option to expand networking further with an Open Compute Project 3.0 card
Below are the specs for the OCP 3.0

Dell's RAID controller lineup includes the fPERC solution, offering a base RAID hardware controller that bypasses PCIe slot usage through a compact, high-density connector to the base planar.
The 15G PERC controller lineup leans heavily on the prior family, carrying forward the Value Performance tiers. New to the lineup is the Harpoon-based Premium tier, a high-end option built to drive stronger IOPS and enhanced SSD performance.

| Performance Level | Controller & Description |
|---|---|
| Entry | S150 (SATA) SWRAID |
| Value | H345, H355, HBA355 (Internal/External) |
| Value Performance | H745, H755 |
| External Expansions | H840, HBA355e |
The IDSDM and internal USB module can't be used together — only one can be installed, requiring a choice between the two. The IDSDM works well for booting a hypervisor OS.
The internal USB and IDSDM share a single slot, so only one can be installed at a time — a choice between the two is necessary.
The BOSS M.2 drives use a dedicated BOSS riser kit supporting one riser card with 2 M.2 SATA drives — built to boot a full OS system without needing to allocate a separate drive.
