Exact-fit DDR4 SODIMM kit

This 64 GB kit contains two 32 GB DDR4 ECC unbuffered SODIMMs rated at 2933 MHz with CL21 latency and 1.2 V operation. It is built for Supermicro X12SCV-W and X12SCV-LVDS motherboards that require 260-pin modules.

DDR4 SODIMM limits

DDR4 SODIMM slots accept only 260-pin unbuffered modules; full-size UDIMMs or registered RDIMMs will not fit or function. The memory controller must support ECC operation for the error-correction feature to be active.

Check your system manual

Verify that your specific model supports 64 GB total capacity and the approved population order for two dual-rank modules. Confirm the BIOS is updated to recognise the kit at its rated speed and timings.

Questions about this item

Should I choose the 64GB 2x32GB kit or a single 32GB module for my Supermicro X12SCV motherboard?

The 64GB kit provides two matched 32GB modules (2Rx8, CL21, 1.2V) designed to run together at DDR4-2933. A single module would halve capacity and may not meet the board's population rules for full-speed operation.

What does the DDR4-2933 (PC4-23400) speed rating mean once installed in my system?

The modules are rated to transfer data at 2933 MT/s with a peak bandwidth of PC4-23400. The memory controller will run them at this speed with CL21 latency when the BIOS applies the correct timing table for the 2Rx8 ECC SODIMMs.

How does the 260-pin SODIMM ECC unbuffered interface affect compatibility and performance limits?

The 260-pin SODIMM form factor fits only SODIMM slots — not full-size UDIMM or RDIMM sockets. Unbuffered ECC means the memory controller talks directly to the DRAM, so the 2Rx8 rank structure and 1.2V operation must match the Supermicro X12SCV memory population rules for the kit to be recognised at full 64GB capacity and 2933 MT/s.
