32 GB DDR5 ECC RDIMM for servers

This 32 GB DDR5 module runs at 4800 MHz and uses ECC registered technology. It targets servers and workstations that require error-correcting memory for data integrity. The 2Rx8 organisation supports high-density configurations in multi-socket platforms.

Check DDR5 RDIMM slot availability and voltage

Verify that your motherboard provides 288-pin DDR5 RDIMM slots and operates at 1.1 V. Registered DIMMs need a compatible chipset and BIOS that support ECC and registered operation. Unbuffered or non-ECC boards will not accept this module.

Fits registered DDR5 channels alongside identical

The module occupies one 288-pin slot and draws 1.1 V, leaving remaining channels free for matching RDIMMs. Populating all channels with identical 2Rx8 sticks maximises bandwidth and maintains signal integrity. Mixed ranks or voltages can reduce stability.

商品問答

What comes with the Samsung M321R4GA3BB0-CQK module and do I need extra parts?

The package contains the 32 GB DDR5 4800 registered ECC RDIMM itself. No cables, brackets or additional components are required for installation in a compatible server or workstation motherboard.

How do I decide between the listed capacity and rank options for this part number?

This MPN is a single 32 GB module built as 2Rx8. Choose it when your system needs a 32 GB registered ECC DIMM at DDR5 4800; other capacities or ranks would carry different part numbers.

What does the DDR5 4800 rating mean once the module is installed in a server?

The memory operates at 4800 MT/s with a PC5-38400 designation, delivering the rated speed when the platform supports DDR5 4800 and the DIMM is seated in a 288-pin registered slot at 1.1 V.
