128GB DDR4 kit for Supermicro workstations

This 128GB kit contains eight 16GB unbuffered UDIMM modules built for Supermicro desktop and workstation motherboards such as the MBD-C9X299-PGF. It targets professionals who need maximum memory capacity in a single system without moving to registered or ECC memory. The kit arrives new and ready to install.

Eight modules at 2933 MT/s with CL21 timing

Each 1Rx8 module runs at DDR4 2933 (PC4-23400) with a CAS latency of 21 and operates at 1.20V. The 128GB total provides ample headroom for large datasets, virtual machines and heavy multitasking, while the non-ECC unbuffered design means error correction and registered buffering are not available for mission-critical server workloads.

288-pin UDIMM form factor fits standard DDR4 slots

The modules use the common 288-pin DDR4 UDIMM layout and require no heat spreader, leaving clearance for large CPU coolers. Builders must confirm their motherboard supports eight unbuffered DIMMs at this speed and density, as some platforms limit rank count or maximum capacity per channel.

Questions about this item

Will the 8×16GB DDR4 2933 CL21 UDIMM kit run alongside my existing DDR4 modules without errors?

The kit is DDR4 2933 CL21 1.20V 1Rx8 unbuffered non-ECC UDIMM. Mixing speeds or ranks can cause the system to downclock or become unstable; use identical modules for best results.

How can I verify the 128GB DDR4 2933 CL21 kit is operating at its rated speed after installation?

Enter the UEFI/BIOS and confirm the memory frequency reads 2933 MT/s (PC4-23400) with CL21 timings at 1.20V. CPU-Z or dmidecode will also show 2933 MHz per module.

What does the 128GB DDR4 2933 CL21 UDIMM kit include and what must I buy separately?

The box contains eight 16GB 288-pin DDR4 UDIMM modules (MD23400-618K8). No heat spreaders, cables, tools or additional parts are included.
