  • 2V operation meets JEDEC standard
  • 288-pin 4Rx4 RDIMM form factor

Server-grade 128GB DDR4 RDIMM

This single 128GB DDR4 3200MHz module uses a 288-pin registered ECC design with CL22 latency and 1.2V operation. It is built for workstations and servers that require registered memory and cannot be used in standard desktop computers or mixed with unbuffered modules.

JEDEC-compliant registered ECC module

The module meets JEDEC standard specifications and is ROHS compliant, providing a warranty-safe upgrade path. Its 4Rx4 rank configuration and registered buffer help maintain signal integrity in multi-DIMM server configurations, while ECC support detects and corrects single-bit errors.

Verify registered ECC support before ordering

Confirm that your motherboard and CPU explicitly support DDR4 registered ECC RDIMMs and that the memory controller accepts 4Rx4 modules at this capacity. Systems limited to unbuffered non-ECC memory or lower rank counts will not recognise this module.

Questions sur cet article

Does the 128GB 4Rx4 registered module need any periodic maintenance or component replacement after installation?

No — the module has no heat spreader, no moving parts and no user-serviceable components, so it runs for its service life without scheduled maintenance.

What limit appears first when the 3200MHz CL22 1.2V DIMM runs at full load continuously?

The CAS latency of 22 cycles at 3200MHz sets the timing ceiling; sustained throughput cannot exceed the JEDEC PC4-25600 bandwidth the module is rated for.

How much heat and power does the 288-pin 128GB stick produce during all-day operation?

It draws 1.2V with no onboard heat spreader, so thermal output stays at the level defined by the JEDEC DDR4 3200 registered specification.
