Capacity and role

This 64 GB DDR4 module is built for workstation and server platforms that require ECC and registered operation. The dual-rank 2Rx4 design delivers high density in a single 288-pin DIMM slot.

Upgrade path

Replacing lower-capacity or non-ECC DDR4 DIMMs with this module adds 64 GB of registered memory per slot, enabling larger datasets and more virtual machines. The jump is worthwhile when the motherboard supports registered ECC memory and the workload exceeds the current memory ceiling.

Fit and alternatives

Suited for administrators expanding memory in qualified server or workstation boards that accept registered DDR4 ECC DIMMs. Builders using consumer desktop platforms or boards that only support unbuffered memory should look elsewhere.

Questions about this item

Will this 288-pin DIMM fit my server board?

The module uses the standard 288-pin DDR4 DIMM form factor, so it fits any server motherboard with DDR4 slots.

Do I need to enable anything in BIOS for this registered ECC memory?

Install the DIMM, then enter BIOS to confirm ECC and registered mode are active; the step often missed is saving the memory configuration before exiting.

When should I plan to replace this 64 GB DDR4-3200 module?

Server memory has no scheduled replacement; replace only if diagnostics report correctable ECC errors rising or the module fails POST.
