OWC 1TB DDR4 ECC LRDIMM Kit

This OWC kit delivers 1TB of DDR4 3200 memory across eight 128GB modules. Each 288-pin LRDIMM runs at 1.2V with CL22 latency and 4Rx4 organisation. The load-reduced design includes ECC for data integrity in server workloads. It targets HP ProLiant Gen10 Plus platforms listed in the compatibility data.

Who This Suits And Who Should Look Elsewhere

System administrators upgrading DL325 Gen10 Plus v2, DL345, DL360, DL365 or DL380 Gen10 Plus servers will find a validated match. Buyers needing unbuffered or standard registered DIMMs cannot use this kit because load-reduced modules cannot mix with those types. Desktop builders and workstation users requiring non-ECC memory must choose a different product.

Deciding Specification Load-Reduced ECC

The defining attribute is the load-reduced ECC DDR4 architecture. This module type only functions in platforms engineered for LRDIMM signalling and cannot operate in slots wired for unbuffered or registered memory. Verify the server documentation calls for LRDIMM before purchasing.

Questions about this item

What does the 3200 MHz rating mean when the modules are installed in a compatible HP ProLiant server?

The modules run at 3200 MHz (PC4-25600) with CL22 latency when the server memory controller supports that speed; otherwise they automatically down-clock to 2933, 2666, 2400 or 2133 MHz.

How does the DDR4 LRDIMM interface affect maximum capacity per slot in these servers?

Load-reduced DIMMs buffer the electrical load so each 288-pin slot can accept a 4Rx4 128 GB module, letting the eight-module kit reach 1 TB total.

What physical clearance is needed to fit the 288-pin LRDIMMs in the listed ProLiant models?

Standard 288-pin DDR4 DIMM height applies; the modules have no heat spreader, so they fit the regular memory bays in the DL325 Gen10 Plus v2, DL345, DL360, DL365 and DL380 Gen10 Plus chassis.
