Server-grade DDR5 kit

This 192GB kit contains four 48GB registered DIMMs built for DDR5 6400 platforms that require ECC and 2Rx8 organisation. It targets administrators scaling memory in compatible server chassis. Buyers needing unbuffered desktop modules or non-ECC memory should look elsewhere.

Keyed 288-pin installation

Each module uses the standard 288-pin DDR5 keying, so it seats only in matching registered DIMM slots. The 1.1V operating voltage matches the DDR5 baseline, but the registered buffer adds electrical load that unbuffered platforms cannot handle. Verify motherboard qualification lists before purchase.

Sustained ECC throughput

Registered buffering and on-die ECC keep data integrity stable during continuous workloads such as virtualisation or database caching. CAS latency of 52 cycles at 6400 MT/s delivers consistent bandwidth without the error-correction pauses seen in unbuffered configurations. The four-rank-per-channel density supports large memory maps under prolonged stress.

Questions about this item

How can I verify the kit is running at the advertised 6400MHz speed after installation?

Enter the system BIOS or use a tool such as CPU-Z to confirm the memory frequency reads 6400MHz and the CAS latency shows 52.

What exactly ships in the box and is anything else required to use it?

The box contains four 48GB DDR5 ECC RDIMM modules for a total of 192GB; no extra cables or brackets are needed, just a compatible server motherboard with 288-pin DDR5 slots.

This kit is only offered as 192GB (4 x 48GB) — how do I decide if that capacity is right for my server?

Choose this 192GB kit when your workload needs maximum registered ECC capacity per channel and the board supports four 2Rx8 DDR5 6400 modules at 1.1V.
