Hynix

Hynix HMT351R7EFR8A-Pb switch module

SKU CH-0W9C-ME4M8

4 Gb ECC registered SDRAM module at 1.35 V with CL11 latency and 240-pin dual-rank layout

  • ECC registered design guards data integrity in critical workloads
  • Low 1.35 V operation cuts power draw versus standard modules
  • Dual rank layout maximises density on a single 240 pin DIMM
  • 31600 MT/s speed rating supports high throughput server tasks

Hynix 4Gb PC3L-12800R Registered Memory

This Hynix 4Gb module operates at 31600 MHz with a CAS latency of 11. It uses a 240-pin form factor and runs at 1.35V for lower power consumption. Dual-rank organisation and ECC registration support data integrity in compatible systems.

Suited for servers needing registered ECC DIMMs

Buyers who need unbuffered memory or a different pin count should look elsewhere. Systems that do not support registered modules or require a higher density per DIMM will not be compatible with this part.

Questions about this item

Will the 240-pin module fit my server's memory slot?

The 240-pin form factor matches the industry-standard registered DIMM socket used in most servers, so it seats directly without an adapter.

What is the correct way to seat the 240-pin module and the step often missed?

Align the notch with the slot key, press down firmly until both retaining clips click into the module's side notches, verifying the 1.35 V requirement matches the platform.
