1 TB ECC LRDIMM kit for HP Gen10 servers

This kit provides 1 TB of DDR4 2933 memory using eight 128 GB load-reduced DIMMs. It is built for HP ProLiant BL460c, DL325, DL360, DL380 and DL385 Gen10 platforms that require ECC load-reduced modules.

Verify your server uses load-reduced ECC DIMMs

The modules are 288-pin DDR4 LRDIMMs operating at 1.2 V with CL21 latency. They will not work in systems that need unbuffered or standard registered ECC memory, and they cannot be mixed with those types.

Runs at standard 1.2 V with backward speed support

The kit follows JEDEC DDR4 specifications and is rated for PC4-23400 at 2933 MHz. It will also operate at 2133, 2400 or 2666 MHz when installed in compatible slots, drawing the same 1.2 V supply.

Questions about this item

What does the 1 TB kit include and do I need to buy anything else?

The kit contains eight 128 GB DDR4 2933 CL21 4Rx4 LRDIMM modules. No extra parts are required for installation in a compatible server.

Why choose the 1 TB eight-module kit instead of a smaller capacity?

It fills eight DIMM slots with 128 GB LRDIMM modules, delivering 1 TB total capacity for HP ProLiant Gen10 servers that support load-reduced memory.

What does the 2933 MHz rating mean once the memory is installed in a Gen10 server?

The modules run at 2933 MHz (PC4-23400) with CL21 latency at 1.2 V, and will down-clock to 2666, 2400 or 2133 MHz if the platform requires it.
