Exact-match server upgrade

This 1.5TB kit delivers twelve 128GB DDR5-6400 registered ECC RDIMMs built for the Supermicro H14DST-F motherboard. The modules match the board's required 2Rx4 rank structure, 1.1V operating voltage and CL52 timing so the memory controller recognises full capacity at rated speed.

Registered ECC stability

Each 288-pin RDIMM uses a registered architecture that buffers address and command signals, allowing all twelve slots to run fully populated without overloading the controller. On-die ECC corrects single-bit errors in real time, preventing silent data corruption and unplanned reboots in production workloads.

Twelve-module population kit

The package supplies the complete 12x128GB configuration in a single matched set, removing the risk of mixing revision codes or timing bins across separate purchases. Installers must still follow the motherboard manual for approved DIMM population order and any BIOS settings required for full-speed operation.

Questions about this item

What DDR5 speed and PC5 bandwidth does this 12-module kit run at?

The kit operates at DDR5 6400 with a PC5-51200 data rate, so every module transfers at that rated speed when the motherboard supports it.

What physical slot and form factor must the Supermicro H14DST-F provide for these 288-pin RDIMMs?

The board needs standard 288-pin DDR5 RDIMM slots; the modules are registered ECC DIMMs and will not fit UDIMM or SODIMM sockets.

In what order should the 12 DIMMs be populated on the H14DST-F to avoid a no-post condition?

Follow the motherboard manual's exact population sequence for 12 DIMMs per CPU; skipping the prescribed slot order is the most common cause of boot failure.
