System-specific DDR4 kit

This 64 GB kit contains two 32 GB DDR4 UDIMMs rated at 2933 MT/s with CL21 latency. It is built for Supermicro workstations such as the SuperWorkstation 5039AD-I and the C9X299-PGF motherboard, delivering a straightforward capacity upgrade for supported platforms.

DDR4 2933 interface limits

The modules run at the standard 1.20 V and use the 288-pin DDR4 UDIMM form factor, so they only fit boards wired for DDR4. Speed is fixed at PC4-23400 with 2Rx8 organisation, and the lack of ECC or registered buffers means they cannot be used in systems that require error-correcting or registered memory.

Unbuffered modules without spreaders

Each stick is an unbuffered UDIMM without a heat spreader, keeping the profile low for tight server or workstation chassis. The 288-pin edge connector aligns with standard DDR4 slots, and the kit is validated for the listed Supermicro models to ensure stable operation in those configurations.

Questions about this item

Should I choose the 64GB kit or look for a single 32GB module for my SuperMicro system?

The kit provides two matched 32GB modules for dual-channel operation; a single module would run in single-channel mode and reduce memory bandwidth.

What does the 2933 MT/s rating mean once the modules are installed in my SuperMicro workstation?

The memory will run at up to 2933 MT/s if the CPU and motherboard support that speed; otherwise it will downclock to the highest speed the platform allows.

Is the 288-pin DDR4 UDIMM interface compatible with standard desktop motherboards or only SuperMicro server boards?

The 288-pin DDR4 UDIMM form factor fits any desktop or workstation board with DDR4 UDIMM slots, but this kit is validated for the listed SuperMicro systems.
