Server-grade 64GB DDR4 ECC module

This single 64GB DDR4 3200 CL22 2Rx4 288-pin ECC Registered RDIMM is built for Gigabyte G242-P34, G242-P35, G242-P36, G242-Z10 and G242-Z11 platforms. It delivers 1.2V JEDEC-standard operation with error-correcting code and registered buffering for data integrity in multi-tasking workloads. The module targets administrators upgrading compatible workstations, servers or NAS systems. Buyers needing unbuffered desktop memory or load-reduced DIMMs cannot use this product.

Registered ECC interface constraints

The registered buffer adds one clock cycle of latency and requires a motherboard chipset that supports registered DIMMs; standard consumer desktop boards will not post with this module. Mixing with unbuffered or load-reduced ECC memory is not supported and will prevent boot or cause instability. Backward compatibility covers 2133, 2400, 2666 and 2933 MT/s speeds when the platform dictates a lower data rate. Systems lacking registered ECC support in the memory controller are excluded.

64GB capacity for virtualization headroom

A single 64GB stick lets compatible dual-socket boards reach high aggregate memory totals without consuming every slot, supporting dense virtual-machine deployments and large in-memory databases. Workloads that exceed the per-channel rank limit or require load-reduced DIMMs for higher capacities will need a different module type. The 2Rx4 organisation suits platforms optimised for dual-rank registered DIMMs. Buyers whose chassis or CPU memory-controller limit total installed memory below the desired target must verify platform maximums before purchasing.

Questions about this item

Should I choose this 64GB module or a smaller capacity for my Gigabyte G242 server?

This single module provides 64GB of DDR4 3200 ECC Registered memory. Select it if your workload needs that density per slot and your system supports 2Rx4 registered DIMMs.

What does the 3200MHz speed actually deliver in a Gigabyte G242-P34?

The module runs at DDR4 3200 (PC4-25600) with CL22 latency. In your G242-P34 it will operate at the highest speed the platform and memory controller allow, down to 2133MHz if required.

Is the 288-pin ECC Registered RDIMM interface compatible with standard desktop motherboards?

No. The 288-pin DDR4 ECC Registered RDIMM form factor is designed for servers and workstations such as the Gigabyte G242 series. It will not work in standard desktop boards that require unbuffered memory.
