64 GB DDR5-4800 Registered ECC Module

This SK hynix RDIMM provides 64 GB of DDR5 memory rated at 4800 MT/s with CL40 latency. It is a dual-rank, registered module with ECC and load-reduced signalling for stable operation in multi-module configurations. The 288-pin form factor fits standard DDR5 server slots.

Suited for servers needing maximum capacity per slot

The dual-rank 64 GB density helps reach high total memory without filling every channel. It is not for consumer desktops or workstations that only accept unbuffered UDIMMs. Systems requiring single-rank modules for specific timing rules should look elsewhere.

Verify DDR5 RDIMM support and slot count

Confirm the motherboard and CPU memory controller accept registered DDR5 ECC LRDIMMs at 4800 MT/s. Check how many 288-pin slots are free and whether the platform limits total capacity or rank count per channel. Match the module voltage and thermal profile to the system design.

商品問答

Does my server motherboard need DDR5 RDIMM slots to use this 64GB module?

Yes, this module uses the 288-pin DDR5 RDIMM form factor and requires a motherboard with DDR5 RDIMM slots.

Can I mix this dual-rank ECC registered module with single-rank RDIMMs already in my system?

Mixing ranks is possible if the motherboard supports it, but population rules vary by platform; check the board manual for supported rank combinations.

How do I verify the CL40 timing and 4800 MT/s speed are active after installation?

Enter the system BIOS or use a tool like CPU-Z to confirm the memory reports DDR5-4800 with CL40 latency.
