SuperMicro Compatible DDR4 Kit

This 64 GB kit contains two 32 GB unbuffered UDIMM modules built for SuperMicro desktop and workstation motherboards. It targets system builders and IT professionals who need validated memory for compatible platforms. The non-ECC design suits standard workstation workloads rather than mission-critical server deployments. Installation follows the standard 288-pin DDR4 process described in the motherboard manual.

DDR4 2933 CL21 Specification

The modules run at DDR4 2933 (PC4-23400) with a CAS latency of CL21 at 1.20 V. This speed and timing combination is the single specification that determines whether the kit matches the motherboard's qualified-vendor list. Builders must verify that their specific SuperMicro board supports DDR4 2933 non-ECC unbuffered memory before purchase. The 2Rx8 rank organisation is fixed by the module design.

64 GB Capacity and Headroom

The 64 GB total capacity handles large datasets, virtual machines and multi-application workflows on supported SuperMicro workstations. Dual-channel population with two modules leaves remaining slots open for future expansion if the board provides more than two DIMM slots. Systems requiring ECC error correction or registered memory will not be compatible with this non-ECC unbuffered kit.

Questions sur cet article

What does 2933 MT/s mean once the kit is installed in a Supermicro workstation?

The modules run at 2933 MT/s, delivering PC4-23400 bandwidth so the CPU sees the full rated throughput without manual tuning.

How does the DDR4 288-pin UDIMM interface limit performance in practice?

The unbuffered DDR4 UDIMM slot caps transfer rate at 2933 MT/s and does not support ECC, so data integrity relies on the CPU alone.

What physical clearance does the 288-pin UDIMM need on the Supermicro C9X299-PGF board?

Each 32 GB stick is a standard-height 288-pin UDIMM with no heat spreader, so it fits the regular DIMM slots without extra clearance.
