32GB DDR4 3200 ECC RDIMM

This 32GB DDR4 3200 module is an ECC Registered RDIMM built for servers and workstations that require error-correcting, registered memory. It operates at 1.2V with a CAS latency of 22 and uses a 2Rx4 organisation across 288 pins. It will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs.

Sustained load behaviour

The module meets JEDEC-standard specifications and is tested to maintain stability under continuous server workloads. Registered buffering reduces electrical load on the memory controller, helping signal integrity during extended operation. ECC circuitry corrects single-bit errors and detects multi-bit errors without halting the system.

DDR4 interface limits

DDR4 3200 (PC4-25600) sets the maximum transfer rate for this DIMM; the memory controller and motherboard must support this speed to realise it. Population rules for registered DIMMs and the platform's maximum supported capacity limit how many modules can be installed. Mixing with unbuffered memory is not supported.

Questions about this item

Does the 1.2 V rating keep power draw low when the 32 GB module runs continuously in a server?

The module operates at the standard DDR4 1.2 V, which is the JEDEC voltage for this speed grade and helps limit heat during all-day workloads.

What motherboard feature is required for this 288-pin registered ECC RDIMM to function?

The system must provide a DDR4 RDIMM slot with registered ECC support; standard desktop boards that only accept unbuffered memory will not work.

Will this PC4-25600 CL22 stick run reliably alongside older DDR4 registered ECC DIMMs of a different speed grade?

All installed DIMMs will operate at the lowest common speed and tightest shared timings, so mixing speed grades is possible but reduces overall bandwidth.
