Server DDR4 ECC RDIMM module

This 8 GB registered DIMM runs at DDR4 2666 with CL19 timing and 1.20 V. It targets administrators upgrading or repairing server and workstation platforms that require error-correcting memory.

Equivalent to Kingston KSM26RS8/8MRR

The module is validated as a direct replacement for that Kingston part number, simplifying procurement when the original SKU is unavailable. Major-brand chips and registered buffering maintain signal integrity in multi-DIMM configurations.

Verify platform support for registered ECC DDR4

Confirm the motherboard or system accepts 288-pin registered ECC DIMMs at this speed and rank before ordering. Consumer desktop boards and laptops typically do not support registered memory.

Perguntas sobre este artigo

Will the registered DIMM require any firmware updates or battery replacements over its service life?

No firmware updates or battery replacements are needed; the module is a passive DDR4 component that operates at 1.20V and is validated for continuous server workloads.

What thermal limit appears first when the module runs at 2666 MHz under sustained load?

The JEDEC-rated 1.2V operating voltage is the primary constraint; exceeding it would breach the DDR4 specification before any other thermal threshold is reached.

How much heat and power does the 1Rx8 registered module draw during all-day operation?

At the standard 1.2V DDR4 voltage the 8GB stick draws minimal power and produces low heat, typical for a single-rank registered DIMM in a 288-pin slot.
