32GB DDR4-2133 ECC REG module

This Samsung module provides 32GB of DDR4 memory rated at 2133MHz with a PC4-17000 designation. It operates at 1.2V with CL15 latency and uses a 288-pin DIMM form factor. The part number is M393A4K40BB0-CPB.

Server and workstation builders needing registered

This dual-rank x4 module suits systems that require registered DIMMs with error-correcting code for data integrity. It is not for desktop boards that accept only unbuffered non-ECC memory. Buyers who need lower-density sticks or a different speed grade should look elsewhere.

Registered ECC with dual-rank x4 organisation

The module is registered and carries ECC, organised as 2Rx4 with a 4G x 72 configuration. This specific architecture decides whether the memory will initialise on a given platform. Verify that your motherboard and CPU support registered dual-rank ECC DDR4 before purchase.

商品問答

Does the 288-pin DDR4 module fit a standard desktop DIMM slot?

Yes, the 288-pin DDR4 module fits a standard desktop DIMM slot. The low-profile 2Rx4 design measures 32GB at 2133MHz with CL15 timing and 1.2V operation.

How do I install the registered ECC memory correctly?

Align the notch on the 288-pin module with the slot key, press firmly until both retention clips click. The step people miss is verifying the motherboard supports registered ECC DDR4 before purchase.

When will the 32GB DDR4-2133 kit need replacement?

The module has no moving parts and requires no scheduled replacement. Run a memory test at build time; if errors appear later, swap the stick. RoHS compliance means no hazardous materials to degrade.
