Server DDR5 ECC Registered Kit

This A-Tech kit supplies 128GB of DDR5 4800 ECC Registered memory in two 64GB 2Rx4 modules. It is built for servers and workstations that require error-correcting registered DIMMs. The dual-channel kit runs at 1.10V with a CAS latency of 40. Systems needing registered ECC DDR5 at this speed and density will use this memory directly.

For DDR5 Servers and Workstations Only

This memory suits administrators upgrading compatible DDR5 servers or workstations that accept 288-pin EC4 RDIMM modules. It will not function in desktop PCs, laptops or any platform that uses unbuffered non-ECC DDR5 or earlier DDR generations. Buyers whose systems require unbuffered memory or a different form factor must select a different product type.

2Rx4 Registered ECC DDR5 at 4800 MHz

The decisive specification is the 2Rx4 Registered ECC DDR5 4800 configuration on a 288-pin DIMM. Only systems qualified for this exact module type, rank organisation and voltage will accept the kit. Verify the motherboard or server manual for supported memory before ordering.

Soalan tentang produk ini

My server board only has DDR5 slots — will these 288-pin 1.10V modules seat correctly?

Yes, each module is a 288-pin DDR5 RDIMM built for 1.10V operation and will fit any server board with DDR5 registered DIMM slots.

Can I add this 2Rx4 kit to existing 1Rx4 DDR5 RDIMMs in the same channel?

Mixing dual-rank x4 modules with single-rank x4 modules in the same channel is not recommended; populate identical ranks per channel for stable operation.

How do I confirm the kit runs at 4800 MHz with CL40 after installation?

Enter the system BIOS or use a hardware utility such as CPU-Z; the memory tab should show 4800 MT/s and CAS latency 40 for each 64 GB module.
