Upgrading Dell PowerEdge R670 with SSDs and RAM involves selecting Dell-validated components for compatibility and warranty compliance. The R670 CSP Edition supports 8 x E3.S NVMe SSDs and 32 DDR5 DIMM slots (up to 6 TB RAM). For SSDs, use Dell Express Flash NVMe PCIe drives for optimal performance. RAM upgrades require DDR5 modules installed in pairs across CPU zones. Always prioritize Dell-certified hardware to avoid system errors or warranty voidance.
Which Dell PowerEdge Server Should You Choose: R840, R940, or R940xa?
What SSD types are compatible with PowerEdge R670?
PowerEdge R670 supports 8 x E3.S NVMe SSDs, specifically Dell Express Flash drives like the PM1745 or PM1655 series. Non-Dell SSDs risk instability due to firmware mismatches. Pro Tip: Check Dell’s Compatibility Matrix for validated models before purchase.
Beyond storage capacity, the R670’s E3.S form factor delivers high-density PCIe Gen5 performance with up to 14 GB/s throughput per drive. For installation, follow Dell’s hot-swap guidelines to avoid data corruption. For example, inserting a PM1745 6.4 TB NVMe SSD requires sliding it into the bay until the latch clicks, then initializing it via iDRAC. However, using third-party SSDs—even with identical specs—may trigger firmware errors. Why risk downtime? Stick to Dell-certified drives.
| Dell SSD Model | Capacity | Sequential Read |
|---|---|---|
| PM1745 | 6.4 TB | 14 GB/s |
| PM1655 | 3.2 TB | 12 GB/s |
How to install RAM in PowerEdge R670?
The R670 has 32 DDR5 DIMM slots, supporting up to 6 TB with 128 GB modules. Use Dell-qualified DDR5-4800 MHz RAM for best performance, and populate slots symmetrically across both CPUs.
Practically speaking, start by installing DIMMs in slots A1/A2 and B1/B2 for each processor to maximize channel bandwidth. Mixing RAM capacities (e.g., 64 GB and 128 GB in the same channel) can reduce speed to the lowest common denominator. Wecent’s engineers recommend using identical Dell DDR5-4800 modules—like the 64 GB DDR5-4800—to avoid timing mismatches. What if you skip Dell-certified RAM? The system may POST but run at degraded speeds (e.g., 3600 MHz instead of 4800 MHz).
| Module Type | Max per Slot | Speed |
|---|---|---|
| Dell 64 GB DDR5 | 128 GB | 4800 MHz |
| Third-Party 64 GB DDR5 | 128 GB | 3600–4800 MHz* |

FAQs
No—the R670 CSP Edition exclusively supports DDR5. DDR4 modules are physically incompatible and will damage the motherboard.
Are SAS SSDs supported on PowerEdge R670?
Only NVMe E3.S drives are supported. The R670 CSP lacks SAS/SATA backplanes, making SAS SSDs unusable.
