128GB DDR3L ECC RDIMM kit

This kit provides 128GB of DDR3L ECC registered memory across four 32GB modules. It is built for workstations and servers that require error correction and registered buffering. Standard desktop computers cannot use this memory type. Mixing it with unbuffered modules is not supported.

DDR3L 1600 CL11 1.35V limits

The modules run at DDR3L 1600 (PC3L-12800) with CL11 latency at 1.35V. This voltage is lower than standard DDR3, so the platform must explicitly support DDR3L operation. Registered buffering adds one clock cycle of address delay, which the memory controller must expect. Systems limited to lower speeds or higher voltages will not be compatible.

240-pin 4Rx4 build for Supermicro X9DR

Each module uses a 240-pin 4Rx4 organisation without a heat spreader, relying on chassis airflow for cooling. The kit is validated for Supermicro X9DRFF, X9DRFR, X9DRG, X9DRH and X9DRi motherboard series. Installation follows standard DIMM slot population rules for the target board.

Questions about this item

Should I choose the 128GB kit or buy individual 32GB modules?

The kit supplies four matched 32GB modules for a total of 128GB, ensuring identical timings and rank configuration across all slots.

What does the PC3L-12800 rating deliver in a running system?

It provides a peak transfer rate of 12800 MB/s at 1600 MT/s with CL11 latency, operating at the DDR3L 1.35V voltage level.

How does the 240-pin DDR3L ECC registered interface limit performance?

The registered buffer adds one clock cycle per command, capping usable speed to the JEDEC 1600 MT/s spec and preventing mixing with unbuffered DIMMs.
