SKU CH-4SS5-7NRFM

1TB DDR4-2933 ECC Load-Reduced quad-kit for Supermicro H12SST-PS servers

Capacity 1TB (4 x 256GB)

  • ECC load-reduced design protects data integrity in servers
  • 1 TB kit of four 256 GB modules maximises capacity
  • DDR4 2933 MHz CL21 delivers high throughput
  • 2 V operation lowers power draw per module
  • Backward compatible with 2133, 2400 and 2666 MHz systems

1TB ECC Load-Reduced DDR4 Kit

This 1TB kit contains four 256GB DDR4 2933 PC4-23400 CL21 288-pin 1.2V ECC Load Reduced LRDIMM modules. It is built for Supermicro H12SST-PS motherboards in server, workstation and NAS platforms. The memory will not work in standard desktop computers and cannot be mixed with unbuffered or ECC registered DIMMs.

Upgrade from lower-capacity LRDIMMs

The kit replaces smaller LRDIMM populations to reach 1TB total capacity on the H12SST-PS platform. The jump is worth it when workloads demand larger in-memory datasets or higher virtual-machine density. Modules are backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds if the system requires a lower frequency.

Sustained-load behaviour

JEDEC-standard 1.2V operation and ECC load-reduced architecture maintain signal integrity across all ranks during extended compute passes. The design is tested to meet or exceed OEM specifications for continuous server duty. Buyers who need unbuffered or registered ECC memory instead of load-reduced should choose a different product type.

商品問答

Will the 288-pin LRDIMM modules fit the Supermicro H12SST-PS motherboard slots?

Yes, the 288-pin form factor matches the DDR4 LRDIMM slots on the H12SST-PS motherboard.

What is the correct way to install the 4-module kit, and what mistake should I avoid?

Populate all four slots with the matched 256 GB modules; do not mix these LRDIMMs with unbuffered or registered ECC memory.

When will the 1.2 V DDR4 modules need replacement in a server environment?

They are rated for continuous operation with a limited lifetime warranty; replace only if memory errors appear or capacity needs change.
