Server Memory Upgrade

This is a 64GB DDR4 3200 ECC Registered DIMM built for compatible Fujitsu PRIMERGY servers and workstations. It runs at 1.2V with CL22 latency and a 2Rx4 rank configuration on a 288-pin form factor. The module is JEDEC and ROHS compliant for a warranty-safe installation.

Who This Suits

IT managers upgrading Fujitsu PRIMERGY CX400 M7, TX2550 M5, CX2570 M4, RX2530 M4 or RX2540 M4 systems will find this module validated for those platforms. It is not for standard desktop PCs, laptops or consumer motherboards that only accept unbuffered non-ECC memory. Builders needing load-reduced DIMMs or mixed-rank populations should look at other memory types.

Before Ordering

Confirm your system requires DDR4 ECC Registered RDIMMs and supports 64GB single-module capacity. Verify the memory slots accept 288-pin modules and that the platform allows 2Rx4 organisation. Do not mix this registered module with unbuffered or load-reduced DIMMs in the same system. Ensure all installed DIMMs share the same speed, voltage and manufacturer for optimal stability.

Questions about this item

Do I need a Fujitsu PRIMERGY server that supports DDR4 3200 ECC Registered DIMMs for this 64GB module to work?

Yes, this 288-pin DDR4 3200 CL22 1.2V ECC Registered 2Rx4 DIMM is validated for Fujitsu PRIMERGY CX400 M7, TX2550 M5, CX2570 M4, RX2530 M4 and RX2540 M4 systems.

Can I add this 64GB DDR4 3200 ECC Registered stick alongside existing unbuffered or load-reduced modules in my PRIMERGY?

No, the manufacturer highlights state this registered memory cannot be mixed with unbuffered or ECC load-reduced DIMMs; all slots should use matching registered modules.

How can I confirm the 64GB DDR4 3200 CL22 module is running correctly after installation?

Check the server BIOS or management console to verify the new DIMM appears at 64GB, DDR4 3200 speed, CL22 latency and ECC Registered status without errors.
