Why Choose PHS-MEMORY at DistriNode?
Broad Server Platform Compatibility
PHS-MEMORY modules are validated against a wide range of server platforms, including systems built on Intel Xeon Scalable and AMD EPYC processor families. Whether you are upgrading a rack-mounted 1U/2U server, a blade system, or a tower workstation, PHS-MEMORY publishes platform-specific part numbers such as SP516519 and SP471717/SP471718 to take the guesswork out of compatibility. Always cross-reference with the server's Qualified Vendor List (QVL) or Hardware Compatibility List (HCL) before ordering.
High-Capacity Modules up to 128 GB and Beyond
Need to maximise memory density in a space-constrained chassis? PHS-MEMORY offers high-capacity DDR4 RDIMM and 3DS DIMMs — including 128 GB modules such as the 128GB DDR4 RDIMM 3DS 3200MHz PC4-25600 validated for platforms like the ASRock C621A WS. High-density modules reduce DIMM slot consumption, allowing more RAM per server with fewer physical sticks — ideal for virtualisation hosts, in-memory databases, and SAP HANA deployments.
DDR4 RDIMM & 3DS Specifications Explained
RDIMM (Registered DIMM) uses a register component to buffer the command and address signals between the memory controller and DRAM chips, improving electrical stability at higher capacities and speeds. 3DS (Three-Dimensional Stacked) DRAM stacks multiple DRAM dies vertically within a single package, enabling very high densities (64 GB, 128 GB per DIMM) without sacrificing signal integrity. PHS-MEMORY 3DS modules run at DDR4-3200 (PC4-25600) and are designed for servers that support 3DS-capable memory controllers.
B2B Bulk Ordering for Data Centres
DistriNode supports B2B procurement for data centre expansions, colocation operators, system integrators, and resellers. With over 5,600 PHS-MEMORY modules in stock at prices from €36 to €2,837 per unit, we cater to both targeted single-server upgrades and large-scale memory refresh projects. Contact our B2B team for volume pricing, SKU availability confirmation, and expedited fulfilment on enterprise memory orders.
Find PHS-MEMORY Products at DistriNode
Compatibility tip: Before purchasing server memory, verify your server's QVL (Qualified Vendor List) or HCL (Hardware Compatibility List). Confirm whether your platform requires RDIMM or LRDIMM, and check the channel population rules — most Intel and AMD server platforms require DIMMs to be installed in matched pairs or sets per memory channel for optimal bandwidth. Mixing 3DS and non-3DS DIMMs in the same system is generally not supported.
PHS-MEMORY at DistriNode – Frequently Asked Questions
What server platforms does PHS-MEMORY support?
PHS-MEMORY produces platform-specific server memory modules targeting a broad range of enterprise servers, including those powered by Intel Xeon Scalable processors and AMD EPYC CPUs. Part numbers like SP516519 and SP471717/SP471718 are validated for specific server models, and high-density 128 GB DDR4 3DS modules are explicitly qualified for platforms such as the ASRock C621A WS. Always check the server's QVL or HCL to confirm a specific PHS-MEMORY part number is supported on your exact server model and BIOS revision.
What is DDR4 3DS memory and when should I use it?
DDR4 3DS (Three-Dimensional Stacked) memory uses vertically stacked DRAM dies within a single DIMM package to achieve very high per-DIMM densities — typically 64 GB or 128 GB — that are not possible with conventional planar DRAM. Use 3DS memory when you need maximum RAM density in a server with a limited number of DIMM slots, such as in virtualisation hosts running many VMs, in-memory databases, or HPC workloads. Ensure your server's memory controller and BIOS explicitly support 3DS DIMMs before ordering.
Can I order PHS-MEMORY modules in bulk for a data centre expansion?
Yes. DistriNode holds over 5,600 PHS-MEMORY units in stock and supports bulk B2B orders for data centre operators, system integrators, and enterprise IT departments. Our B2B team can provide volume pricing, confirm SKU availability across the full PHS-MEMORY range, and arrange expedited shipping for large memory refresh projects. Contact us through the DistriNode B2B portal or support channel to discuss your requirements.
