64 GB DDR4 registered ECC module

This 64 GB DDR4 module is built for servers and workstations that require error-correcting code memory. It operates at 1.20 V with a CAS latency of CL22 and uses a 288-pin DIMM form factor. The dual-rank design supports high-density configurations in multi-socket platforms.

Sustained throughput with registered signalling

Registered signal processing adds a clock cycle of buffering to stabilise the command bus under continuous heavy load. ECC corrects single-bit errors on the fly, preventing data corruption during long compute runs. The module runs at the standard DDR4-3200/PC4-25600 rate without exceeding the 1.20 V specification.

DDR4-3200 bus ceiling and dual-rank density

The DDR4-3200 interface caps peak bandwidth at the PC4-25600 limit, so workloads that scale beyond this throughput need faster memory generations. Dual-rank organisation increases capacity per slot but can restrict maximum populated DIMM speeds on some platforms. Systems requiring higher frequencies or lower latencies must move to a newer memory standard.

商品問答

Does the 1.20 V DDR4-3200 module generate noticeably more heat or fan noise when running continuously at full load?

Operating at the standard 1.20 V DDR4 voltage, this registered ECC DIMM is designed for sustained server workloads without exceeding typical thermal limits; actual case airflow and CPU cooler capacity determine audible fan levels.

Must the motherboard already support registered ECC DDR4 DIMMs with a 288-pin interface for this stick to function?

Yes — the module requires a server-class platform that accepts registered, ECC-enabled DDR4 memory in the standard 288-pin DIMM form factor; consumer boards without those features will not recognise it.

Can this dual-rank CL22 3200 MHz module share channels with slower CL22 DDR4 DIMMs already installed?

When mixed, all DIMMs on a channel run at the lowest common speed and loosest timings; the system will down-clock this 3200 MHz stick to match the slower modules.
