  • 32 GB server kit (4 × 8 GB) for Supermicro X9 platforms
  • ECC registered DDR3-1333 protects data integrity in critical workloads
  • CL9 9-9-9 timing at 1.5 V delivers stable low-latency operation
  • 2Rx4 organisation on major-brand chips maximises density per DIMM
  • 240-pin DIMM form factor fits qualified Supermicro X9SRW and X9SRL boards

Targeted server upgrade

This 32 GB kit contains four 8 GB DDR3 registered DIMMs built for Supermicro X9SRW and X9SRL platforms. ECC and registered operation protect data integrity in workloads that cannot tolerate silent corruption. The modules run at 1333 MHz with CL9 timing at 1.5 V.

240-pin registered layout

Each stick uses a 240-pin DDR3 interface without a heat spreader, fitting standard server DIMM slots. Registered signalling reduces electrical load on the memory controller, allowing the full four-module population supported by the listed boards. Major-brand chips are used throughout.

Replaces non-ECC or unbuffered kits

The jump is worth it when moving from consumer memory to a configuration that demands error correction and signal buffering for 24/7 operation. Buyers who need more than 32 GB or who run unsupported motherboards should look elsewhere.

Questions about this item

What speed does the PC3 10600 rating on these DDR3 modules cap at in practice?

The kit runs at 1333 MHz with CL9 9-9-9 timings at 1.5 V, which is the standard DDR3-10600 specification.

Will the 240-pin registered DIMMs fit the Supermicro X9SRW-F and X9SRL-F server boards?

Yes, the 240-pin DDR3 registered DIMMs are listed as compatible with the X9SRW-F, X9SRW-3F, X9SRL-F and X9SRL platforms.

Do I need to populate all four slots in a specific order when installing the 2Rx4 modules?

Install the four 8 GB sticks in the same coloured slot pair per CPU socket; mixing registered and unbuffered DIMMs or skipping the correct channel order will prevent the system from posting.
