Capacity 256GB (8 x 32GB)

Rank 4Rx4

  • ECC registered design protects data integrity in servers
  • 256 GB total capacity across eight 32 GB modules
  • DDR3L 1866 speed with CL13 latency for responsive performance
  • Low 1.35 V voltage reduces power draw and heat
  • JEDEC and RoHS compliant for broad workstation compatibility

256GB DDR3L ECC RDIMM Kit

This 256GB kit contains eight 32GB DDR3L 1866 registered DIMMs with ECC and a CL13 latency. It runs at 1.35V and uses the 240-pin form factor required by compatible workstations and servers. The modules are sold new and tested to meet JEDEC standards.

Suited for registered ECC platforms.

The memory is built for workstations, servers, NAS systems and routers that accept registered ECC RDIMMs. It will not work in standard desktop computers that require unbuffered non-ECC modules. Buyers needing unbuffered memory or a different voltage must choose another kit.

4Rx4 organisation drives capacity and compatibility

Each module uses a 4Rx4 rank configuration to reach 32GB density within the DDR3L 1866 specification. The motherboard must support 4Rx4 registered DIMMs at this speed and voltage. Verify the platform's qualified vendor list before purchase.

이 상품에 대한 질문

What bandwidth does the DDR3L 1866 interface deliver at CL13?

The DDR3L 1866 (PC3L-14900) modules run at 1866 MT/s with a CAS latency of 13, providing a peak transfer rate of 14900 MB/s per module when the memory controller operates at the rated speed.

What physical slot and module dimensions are required for these 240-pin RDIMMs?

Each 32 GB module uses the standard 240-pin DDR3 DIMM form factor and fits a 240-pin DDR3 RDIMM slot; the kit contains eight modules, so eight free registered-DIMM slots are needed.

How do I install the eight modules and which population rule is often missed?

Power down the server, open the chassis, align each module's notch with the 240-pin RDIMM socket, press firmly until the latches click, then populate slots per the system manual's registered-DIMM population order — commonly installing modules in the wrong channel sequence prevents the system from recognising the full 256 GB.
