Green rectangular DDR3 memory module with gold connectors and black chips

SAMSUNG

SAMSUNG M391B1G73BH0-CH9 8GB DDR3 1333MHz PC3-10600 240-pin CL9 dual rank ECC unbuffered DIMM memory upgrade

SKU CH-W3TP-FW46D

8 GB DDR3 1333 MHz ECC unbuffered DIMM with CL9 timing for server upgrades

  • 8 GB capacity supports larger server workloads
  • 1333 MHz DDR3 speed matches PC3-10600 bandwidth
  • CL9 latency keeps response tight under load
  • ECC protection corrects single-bit errors automatically

Server-grade ECC DIMM for DDR3 platforms

This 8 GB DDR3 module is built for servers and workstations that require error-correcting code memory. It operates at 1333 MHz with a CL9 latency and uses a 240-pin unbuffered dual-rank design. The PC3-10600 rating confirms its standard bandwidth specification.

Practical limits of DDR3-1333 ECC unbuffered memory

The DDR3 interface caps transfer rates at 1333 MT/s, so bandwidth cannot exceed the PC3-10600 ceiling regardless of processor capability. ECC functionality only works on platforms that explicitly support error correction with unbuffered modules. Dual-rank organisation may limit the number of DIMMs a memory controller can address per channel. Builders needing higher densities or faster speeds must select a newer memory generation.
