Server Memory Kit for Enterprise Upgrades

This OWC kit provides 256GB of DDR4 2400MHz ECC Load Reduced memory across eight 32GB modules. It is built for servers, workstations and NAS systems that require registered LRDIMM technology and JEDEC-standard compliance.

Not for Desktop or Unbuffered Systems

The modules use 4Rx4 Load Reduced architecture and will not work in standard desktop computers or any platform that accepts only unbuffered UDIMMs. Buyers needing memory for consumer motherboards or laptops must choose a different product type.

288-Pin LRDIMM Form Factor Decides Fit

Each stick is a 288-pin DDR4 ECC Load Reduced DIMM running at 1.2V with CL17 latency. Verify that your server or workstation board explicitly supports LRDIMM population rules before purchasing.

商品問答

Does my server motherboard need 288-pin DDR4 ECC LRDIMM slots to install this 256GB kit?

Yes, the modules are 288-pin DDR4 ECC Load Reduced DIMMs that only fit server or workstation boards with LRDIMM slots.

Will these 2400MHz CL17 modules run if I keep my existing 2133MHz DDR4 ECC LRDIMMs installed?

The kit is backward compatible with 2133MHz speeds, so both sets can run together at the lower frequency.

How can I confirm the 8x32GB kit is detected as 256GB with ECC active after installation?

Check the BIOS memory summary or run a system tool such as dmidecode to verify 256GB total and ECC status enabled.
