Frequently Asked Questions

What systems is this memory compatible with?

The Micron 64GB DDR5-4800 RDIMM 2Rx4 is RDIMM server memory with ECC error correction. It requires a server or workstation motherboard with RDIMM support. NOT compatible with standard desktop motherboards. Check your server's QVL (Qualified Vendor List) for compatibility.

What speed does this memory run at?

The Micron 64GB DDR5-4800 RDIMM 2Rx4 runs at 4,800 MT/s with CL40 timings. This is a JEDEC standard speed that works automatically without BIOS configuration.

Can I add more memory later?

Yes, the Micron 64GB DDR5-4800 RDIMM 2Rx4 is a single 64GB module. You can add additional compatible DDR5 RDIMM modules to populate empty slots. For best performance, use matched modules of the same speed and capacity to enable dual-channel mode.

Does this memory support ECC error correction?

Yes, the Micron 64GB DDR5-4800 RDIMM 2Rx4 includes ECC (Error-Correcting Code) support, which detects and corrects single-bit memory errors. This is essential for servers, workstations, and mission-critical applications where data integrity is paramount.

What warranty does this memory come with?

The Micron 64GB DDR5-4800 RDIMM 2Rx4 comes with a limited lifetime warranty from Micron.
