Exact DDR5-4800 Registered ECC Kit

This 256GB kit contains sixteen 16GB DDR5 RDIMMs rated at 4800 MT/s with CL40 latency and 1.1V operation. It targets administrators upgrading a Supermicro H14DST-F server that requires registered ECC memory to run every slot at full capacity.

RDIMM Population Rules Apply

The motherboard dictates how many modules it accepts per channel and in which order they must be installed; exceeding those limits prevents the system from booting. Registered buffering lets the memory controller drive all sixteen slots, but only the board's qualified-vendor list confirms which capacities and ranks are supported.

Major-Brand Chips Without Heat Spreaders

Samsung, Micron or Hynix ICs are used depending on supply, and the modules ship bare without heat spreaders to fit dense server chassis airflow paths. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM slots, ensuring mechanical compatibility with the target platform.

Questions about this item

Should I choose the 16 x 16 GB kit or a different capacity for my Supermicro H14DST-F?

This 256 GB kit uses 16 modules of 16 GB each, matching the board's 16 DIMM slots and 1Rx8 rank requirement for full-speed operation.

What does DDR5 4800 actually deliver once installed in the H14DST-F?

The modules run at 4800 MT/s with CL40 latency at 1.1 V, giving the rated PC5-38400 bandwidth when the memory controller is fully populated.

Is the 288-pin RDIMM interface the right fit and what speed ceiling does it impose?

The 288-pin registered DIMM form factor is exactly what the H14DST-F requires; it supports the kit's 4800 MT/s rating without downclocking.
