Capacity 256GB (8 x 32GB)

  • 256GB capacity across eight 32GB modules handles heavy server workloads
  • DDR5 4800 speed with CL40 latency accelerates data-intensive applications
  • ECC registered design with 1Rx4 organisation protects data integrity in critical environments
  • 1V standard DDR5 voltage reduces power draw per module
  • 288-pin RDIMM form factor fits compatible DDR5 server and workstation platforms

Server Memory Kit Capacity

This A-Tech kit provides 256GB of DDR5 server memory across eight 32GB registered DIMMs. Each module runs at 4800 MHz with CL40 latency and 1.10V operation. ECC and registered buffering protect data integrity in multi-socket platforms. The 1Rx4 organisation uses major-brand chips on a 288-pin form factor.

Suited For Registered DDR5 Platforms Only

The modules suit servers and workstations that require DDR5 ECC registered memory with a single-rank x4 layout. Systems that accept only unbuffered UDIMMs, desktop SO-DIMMs or previous DDR generations cannot use this kit. Buyers who need a different rank configuration or lower capacity should verify their platform documentation before ordering.

Steady Throughput Under Load

Registered buffering and on-die ECC keep signal quality stable when all eight slots are populated at 4800 MHz. The 1.10V standard voltage helps maintain consistent power draw during sustained workloads. Single-rank x4 organisation allows the memory controller to keep pages open longer, reducing latency variation during extended compute or virtualisation tasks.

Questions sur cet article

Will this 256GB DDR5 4800 kit work in a server that only accepts registered ECC DIMMs?

Yes, every module in the kit is an EC8 RDIMM with registered ECC, matching the DDR5 registered DIMM requirement.

Can I mix these 1Rx4 modules with existing 2Rx4 DDR5 registered DIMMs in the same server?

Mixing ranks is possible if the platform supports it, but population rules vary by system; consult the server manual for supported rank combinations per channel.

How do I confirm the kit is running at 4800 MT/s with CL40 after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify the configured speed shows 4800 MT/s and CAS latency 40.
