32GB DDR3L ECC Registered Kit

This 32GB kit contains two 16GB DDR3L 1600 registered ECC modules built for the Supermicro X8DTH-i, X8DTH-iF, X8DTi and X8DTi-F server platforms. The low-voltage 1.35V design matches the DDR3L specification used by these systems.

240-Pin Registered DIMM Build

Each stick uses a 240-pin registered layout with a 2Rx4 organisation and CL11 11-11-11 timing. Registered buffering reduces electrical load on the memory controller, a requirement for the supported Supermicro boards. Heat-spreader presence varies by inventory.

Check CPU and Population Rules

The platform supports DDR3-1600 only with Opteron 6200 or 4200 series processors; other CPUs may limit speed. Registered and unbuffered ECC modules must not be mixed. Maximum registered capacity is 128GB across eight sockets with two CPUs, or 64GB across four sockets with one CPU.

Questions about this item

What does the DDR3L 1600 PC3L 12800 rating mean for real-world throughput?

The kit runs at 1600 MT/s with CL11 11-11-11 timings at 1.35 V, giving each 16 GB module a peak transfer rate of 12800 MB/s.

Will these 240-pin DIMMs fit the Supermicro X8DTH-i and X8DTi-F boards?

Yes, they are 240-pin DDR3L registered ECC DIMMs validated for X8DTH-i, X8DTH-iF, X8DTi and X8DTi-F; each board accepts up to 64 GB unbuffered or 128 GB registered across four slots per CPU.

What is the correct installation sequence for a dual-CPU Supermicro server?

Populate the two DIMMs in the same bank (same-colour slots) for each CPU; do not mix registered and unbuffered ECC modules, and use Opteron 6200 or 4200 series processors to enable the 1600 MT/s speed.
