SKU CH-KVWR-58FKG

64GB DDR3 1333 ECC RDIMM kit for Supermicro SuperBlade 7126T and 7226T servers

  • Capacity64GB (4 x 16GB)
  • Type240-Pin DDR3 ECC RDIMM
  • SpeedDDR3 1333 (PC3 10600)
  • CAS LatencyCL9
  • Voltage1.5V
  • ECCYes

Capacity 64GB (4 x 16GB)

  • 64 GB capacity expands server memory headroom with four 16 GB modules
  • DDR3 1333 MHz CL9 speed matches platform spec for stable throughput
  • ECC registered design detects and corrects single-bit errors in critical workloads
  • Validated for Supermicro SuperBlade 7126T and 7226T series ensuring drop-in compatibility
  • 5 V 240-pin RDIMM form factor fits existing server slots without modification

Server-grade memory kit

This 64GB kit contains four 16GB DDR3 1333 ECC registered DIMMs built for Supermicro SuperBlade 7126T and 7226T systems. Each module runs at 1.5V with CL9 latency and a 2Rx4 organisation. The registered design adds a buffer that stabilises the memory bus in multi-DIMM server configurations. It will not work in standard desktop computers or alongside unbuffered memory.

Sustained-load behaviour

ECC circuitry detects and corrects single-bit errors on the fly, preventing data corruption during long compute runs. Registered signalling reduces electrical load on the memory controller, keeping timing margins intact when all four slots are populated. The modules operate within JEDEC DDR3 specifications at 1333 MT/s, delivering consistent throughput for virtualisation, database or storage workloads.

Registered ECC requirement

This kit only fits systems that require DDR3 registered ECC DIMMs; it is incompatible with platforms that accept only unbuffered or non-ECC memory. Buyers whose servers need unbuffered modules or a different DDR generation cannot use this product.

Questions about this item

How much power does each 16GB DDR3 1333 module draw at 1.5V in a fully populated SuperBlade 7126T?

Each module operates at 1.5V DDR3 1333 CL9; total kit capacity is 64GB across four 16GB registered DIMMs, so power scales with all slots filled.

What must the SuperBlade 7126T or 7226T already have to accept this 240-pin ECC registered kit?

The server needs four free 240-pin DDR3 slots that support ECC registered 2Rx4 modules at PC3-10600 1333MHz and 1.5V operation.

Can I keep existing unbuffered DDR3 DIMMs in the SuperBlade 7226T and add these registered modules?

No — registered ECC memory cannot be mixed with unbuffered memory; all slots must use registered modules of matching specification.
