64 GB DDR5 4800 registered ECC module

This 64 GB DDR5 module runs at 4800 MT/s with CL40 timing and 1.10 V operation. It is a 2Rx4 registered DIMM with on-die ECC for data integrity. The 288-pin form factor fits server and workstation platforms that require registered memory.

Suited for high-capacity server deployments

The dual-rank design helps maximize installed memory per channel on compatible motherboards. Registered signalling reduces electrical load on the memory controller. Buyers needing unbuffered DIMMs or lower-capacity modules for consumer boards should look elsewhere.

Registered ECC DDR5 at 4800 MT/s

The registered buffer and ECC function are mandatory for most enterprise platforms. Systems that accept only unbuffered non-ECC memory cannot use this module. Verify motherboard qualification lists before purchase.

Questions about this item

What motherboard slot does the 288-pin DIMM require?

It needs a DDR5 DIMM socket; the 288-pin keying is specific to DDR5 and will not fit earlier DDR generations.

Can I mix this 4800 MT/s registered module with slower DDR5 modules already in my server?

The system will run all modules at the lowest common speed, so existing slower DDR5 memory will set the overall data rate.

How do I confirm the module is running at 4800 MT/s with CL40 timing after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify the reported speed of 4800 MT/s and timings of 40-39-39.
