About the Dell Alienware HS5620
The Dell Alienware HS5620 delivers enterprise-grade expandability powered by 2× Intel Xeon Scalable 4th Gen processors. With 8 memory channels per CPU and 8 DIMM slots, this platform supports up to 2 TB of Registered ECC RDIMMs (1TB with current Kingston parts) using DDR5 RDIMM ECC technology.
The system supports both 4th and 5th Generation Intel Xeon Scalable processors with up to 32 cores per processor. This dual-socket rack server is purpose-built for Cloud Service Provider's most demanding IT applications.
Why Proven Match™ matters: Our methodology converts Intel controller rules and system topology into deterministic memory kits that install cleanly, train at the correct frequency, and eliminate unsupported configurations from ever reaching your cart.

The system supports DDR5 memory modules operating at speeds of 4000 MT/s, 4400 MT/s, 4800 MT/s, 5200 MT/s, and 5600 MT/s depending on processor generation. Memory DIMM slots are not hot-pluggable.
Understanding Speed Behavior
The CPU memory controller determines actual memory bus speed—not the DIMM label alone. At 1 DIMM per channel (1DPC), platforms commonly achieve up to 5600 MT/s. When running 2 DIMMs per channel (2DPC), most controllers step down to 5200 MT/s to maintain signal integrity and stability.
All Proven Match™ listings reflect the configured operational speed, not theoretical maximums.
Bank Schema (Population Map)
Proper memory population is critical for performance and stability. The HS5620 follows specific population rules based on Intel's memory controller requirements.
| Configuration | Population Strategy |
|---|---|
| Fastest (1DPC) | Populate one DIMM per channel across both CPUs |
| Balanced (2DPC) | Add second DIMM per channel, mirrored across CPUs |
| Maximum Capacity | Fill remaining slots symmetrically for maximum memory |
Memory channels are organized across processors with specific slot assignments for optimal performance. Populate memory module sockets only if a processor is installed. For dual-processor systems, sockets A1 to A8 and sockets B1 to B8 are available.
Proven Match™ surfaces only controller-safe, topology-compliant configurations—eliminating guesswork from your upgrade planning.
Compatible Memory Types
Our curated selection includes verified Samsung, Micron, and Hynix modules specifically validated for DDR5 RDIMM ECC operation in the HS5620.
Zero-Mix Policy:
- No mixing RDIMMs with LRDIMMs
- Symmetric densities required per channel
- ECC mandatory for all server workloads
If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module. All DIMMs must be DDR5.
Unsupported combinations are automatically excluded from the Proven Match™ catalog—you'll never see an invalid configuration.
Validation Gates
Every Proven Match™ configuration must satisfy three verification gates before appearing in our catalog:
- JEDEC DDR5 Compliance — Full adherence to industry timing and voltage specifications
- Intel Xeon Scalable 4th Gen Controller Rules — Validated 1DPC/2DPC operation within controller parameters
- OEM Slot Topology Verification — Confirmed compatibility with Dell's memory subsystem design
Only configurations passing all three gates are surfaced—delivering stable, balanced, performance-true memory upgrades.
