High-Capacity DDR4 Kit for Servers

This 64GB kit contains two 32GB DDR4 2666 modules with ECC and a 2Rx8 unbuffered design. It targets server and workstation builds that need large memory capacity and data-integrity protection for virtualization, databases or scientific workloads.

Unbuffered UDIMM Build and ECC Function

The unbuffered UDIMM form factor allows direct installation into compatible server and workstation motherboards without registered buffering. ECC technology detects and corrects single-bit errors and identifies multi-bit errors to maintain data integrity during continuous operation.

DDR4 2666 Speed and Voltage Limits

Rated at DDR4 2666 (PC4-21300) with CL19 latency and 1.2V operation, the modules run at this specific speed and voltage. Systems that require registered DIMMs, higher frequencies, lower latencies or different voltage levels cannot use this kit.

商品問答

What does the PC4-21300 rating mean for real-world DDR4 2666 speed?

PC4-21300 is the JEDEC peak bandwidth label for DDR4 2666 MT/s; the modules run at 2666 MT/s with CL19 latency and 1.2 V.

Will these 2Rx8 UDIMMs fit a standard server DIMM slot?

Yes, they are standard-height unbuffered DDR4 UDIMMs with a 2Rx8 organisation that plugs directly into any DDR4 UDIMM slot.

Do I need to enable anything in BIOS for the ECC to work?

ECC is automatic once the modules are seated in a motherboard that supports unbuffered ECC UDIMMs; no extra BIOS switch is required on the memory itself.
