8GB DDR4 ECC Registered memory for a verified server upgrade
8GBDDR4 3200MT/sECC Registered1Rx8 CL22
The Kingston KSM32RS8/8MR is an 8GB Server Premier DDR4 ECC Registered DIMM specified at 3200MT/s, CL22 and 1.2V. This single-rank 1Rx8 module uses Micron R-die 8Gbit DRAM and a 288-pin registered-with-parity design. Choose it for a server or workstation that explicitly supports this memory type and exact configuration.
Best For: IT teams expanding memory in a server whose manufacturer or Kingston compatibility list specifies this exact part.
Before you order: Check the exact server model, processor, firmware, slot population rules and installed modules before ordering. DDR4 alone does not establish compatibility: this is an ECC Registered DIMM, not desktop UDIMM or laptop SO-DIMM. Actual operating speed follows the supported system configuration. Kingston has issued a phase-out notice for this exact Micron R-die part; a replacement part can have a different capacity and DRAM density. Module images are illustrative; PCB and labels can differ.
What's in the Box
- One 8GB Kingston KSM32RS8/8MR memory module.
What It Means in Practice
- 8GB is the capacity of this single module; plan the total upgrade around existing memory and available slots.
- Follow the server service manual for approved slot placement and supported module combinations.
- Shut the system down and follow its maintenance and antistatic procedures during installation.
What Will Not Work
- Do not select this registered module for a desktop or laptop solely because it uses DDR4.
- 3200MT/s is the module specification, not a promise that every supported server configuration will run at that rate.
- A matching pin count alone does not prove compatibility.

Frequently Asked Questions
Is this ordinary desktop DDR4 memory?
No. It is ECC Registered DIMM memory for systems that explicitly support this memory class and part.
Will it run at 3200MT/s in every server?
The module is specified at 3200MT/s. The actual operating rate depends on the server, processor and memory population.
What does 1Rx8 mean?
The manufacturer identifies a single-rank module using an x8 component organisation. Match it to the server’s supported memory configuration.
Is this a multi-module kit?
This listing is for one 8GB module. Confirm the number of modules required by your upgrade plan.
Singular Expert Insight
Start with the server’s compatibility list and population guide, then select the module. Capacity, generation and pin count are useful checks, but registered-memory support and the exact platform configuration decide whether the upgrade is suitable.
Buyer’s Guide
✓ Buy it if Your exact server configuration supports KSM32RS8/8MR and you need an additional 8GB ECC RDIMM.
✕ Skip it if Your system requires unbuffered desktop memory or laptop SO-DIMMs, or compatibility has not been established.
→ Also consider The server’s approved memory population plan and whether matched modules are needed for the intended configuration.
