32GB DDR4-2400 Registered Kit

This SK hynix kit provides 32 GB of DDR4 memory in four 8 GB modules. The registered design helps stabilise the signal on platforms that require buffered DIMMs. Speed is rated at DDR4-2400 with a CAS latency of 17. Modules operate at 1.20 V and use the standard 288-pin form factor.

Servers needing registered non-ECC memory

Systems that require registered DIMMs without error correction will match this specification. Workstations or consumer boards that accept only unbuffered memory cannot use these modules. Buyers who need ECC protection should select a different kit.

Registered DDR4-2400 at CL17

The registered buffer and CL17 timing at DDR4-2400 define compatibility with qualified server platforms. Verify that the target system supports registered non-ECC DIMMs at this speed before purchase.

商品問答

How much power do four 1.20 V registered modules draw under full load?

Each module operates at 1.20 V; total power depends on the server platform and workload, so consult your system documentation for exact draw.

What motherboard feature is required to use these registered DIMMs?

The motherboard must support registered DDR4 memory; unbuffered consumer boards will not accept these modules.

Can the CL17 2400 MT/s sticks share channels with slower DDR4 modules already installed?

The memory controller will run all populated channels at the speed of the slowest module, so mixing speeds reduces overall bandwidth.
