Server memory kit

This is a 144GB DDR5 ECC RDIMM kit built from six 24GB modules for registered server platforms. It targets administrators who need high-capacity, error-correcting memory in a matched set. The modules are not compatible with standard desktop or laptop motherboards.

DDR5 4800 registered limits

The registered buffer adds one cycle of latency and requires a motherboard with RDIMM support and a DDR5 4800-capable memory controller. Mixing with unbuffered or lower-speed DIMMs will prevent the system from posting. Maximum capacity per channel depends on the specific platform.

2Rx8 organisation at 1.1V

Each module uses a dual-rank 2Rx8 layout running at 1.1V with CL40 timing. This rank configuration determines how the memory controller addresses the chips and must match the server's qualified vendor list. Builders needing single-rank or different voltage modules should choose another kit.

Questions about this item

Should I buy this 144GB kit as six 24GB modules or look for fewer larger sticks?

The kit is supplied as six 24GB RDIMMs; choose it when your server has at least six free DDR5 slots and you want the 144GB total.

What does the 4800MHz rating deliver in an actual server?

It runs at DDR5 4800 with CAS 40 latency at 1.1V, giving the standard PC5-38400 data rate for registered ECC workloads.

Is the 288-pin RDIMM interface compatible with my DDR5 server board?

Yes, these are 288-pin DDR5 ECC RDIMMs (2Rx8, registered) built for server platforms that require registered DDR5 memory.
