8GB DDR4 2666 ECC RDIMM for servers

This 8GB DDR4 2666 ECC registered DIMM is built for server and workstation platforms that require error-correcting memory. It uses a single-rank 1Rx8 layout and runs at the standard 1.20V DDR4 voltage.

Replaces Kingston KSM26RS8 and KTD-PE426S8 modules

The module is a compatible equivalent for several Kingston part numbers including KSM26RS8/8HAI, KSM26RS8/8HCI, KSM26RS8/8HDI, KSM26RS8/8MEI, KTD-PE426S8/8G, KTH-PL426S8/8G and KTL-TS426S8/8G. Upgrading makes sense when your system supports DDR4 2666 registered ECC and you need additional capacity or a direct replacement for a failed stick.

Verify registered ECC support and 288-pin DDR4 slots

Before ordering confirm that your motherboard or server chassis accepts registered ECC DDR4 DIMMs and provides 288-pin slots. Systems that only support unbuffered non-ECC memory will not work with this module.

Questions about this item

Will this 288-pin DDR4 RDIMM fit my server's DIMM slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor and requires a server motherboard with registered DIMM slots that support ECC RDIMM at 1.2V.

How do I install this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then verify in BIOS that ECC is enabled and the speed shows 2666 MT/s.

When should I plan to replace this 8GB 1Rx8 module?

Replace it if memory diagnostics report correctable ECC errors rising over time, or when your workload exceeds 8GB and you need higher capacity modules.
