16GB ECC SODIMM for servers and workstations

This 16GB DDR4 module runs at 2133MHz with CL15 latency and 1.20V operation. It targets technicians upgrading HP systems using part numbers T0H93AA or T0H93AT, plus other platforms that accept unbuffered ECC SO-DIMMs.

ECC unbuffered is the deciding spec

The module is ECC unbuffered, not registered, so it only fits motherboards wired for unbuffered ECC SO-DIMMs. Standard consumer laptops and registered-only server boards will not support it.

Standard 260-pin installation.

Insert the keyed 260-pin stick into an available slot until the latches click; no tools or cables are required. The most common issue is buying ECC memory for a system that cannot enable ECC, leaving the extra parity bits unused.

Questions about this item

What does the 2133 MHz rating mean once the module is installed in a laptop?

The module runs at 2133 MHz, which is the DDR4 2133 standard speed; the system will operate at this frequency or the highest speed the platform supports, whichever is lower.

How does the PC4-17000 designation affect real-world bandwidth?

PC4-17000 indicates a peak transfer rate of 17 000 MB/s; actual throughput is limited by the memory controller and the 2133 MHz clock.

Will the 260-pin SO-DIMM fit in a standard laptop memory slot?

Yes, the 260-pin DDR4 SO-DIMM form factor matches the standard laptop slot; the module is unbuffered ECC and requires a platform that supports ECC memory.
