Capacity & Configuration

This 256GB kit comprises two 128GB DDR4 registered DIMMs built for servers and workstations that require ECC protection. The modules use a 2S2RX4 organisation and major-brand DRAM chips to deliver stable operation under sustained workloads.

DDR4 2666 Registered Limits

The DDR4 2666 interface caps bandwidth at the PC4-21300 rate and requires a platform that supports registered ECC memory. Consumer desktop chipsets and unbuffered-only boards cannot use these modules, so the upgrade path ends at the server or workstation socket.

256GB Headroom

Two ranks per DIMM at 128GB each fill high-capacity slots efficiently, leaving room for additional kits on multi-channel server boards. Workloads that exceed 256GB per channel or demand speeds beyond 2666 MT/s will need faster or larger modules on a compatible platform.

Spørgsmål om denne vare

Should I choose the 256 GB kit with two 128 GB modules or a different capacity?

This kit provides 256 GB total using two 128 GB RDIMMs. Select it when your server needs that exact capacity and has two free DDR4 slots.

What does the 2666 MHz speed mean once the memory is installed in a server?

The modules run at DDR4 2666 (PC4 21300), delivering up to 21 300 MB/s theoretical bandwidth per module when the platform supports that data rate.

How does the 288 pin DDR4 registered ECC interface affect compatibility and performance limits?

The 288 pin registered DDR4 ECC design requires a server or workstation chipset that supports registered memory; it will not work in standard desktop boards and caps speed at the platform's maximum DDR4 2666 capability.
