Capacity and fit

This 16 GB DDR5 module runs at 4400 MHz with CL40 timings and 1.1 V operation. It uses a 288-pin unbuffered DIMM form factor and a 2Rx8 rank structure. The kit contains a single piece built with a major brand chipset.

Speed grade

The decisive figure is DDR5-4400 (PC5-35200) at CL40-40-40-96. All installed memory will run at the slowest module or the processor limit, so matching this exact speed grade matters for consistent performance.

Installation notes

Insert the DIMM into a compatible DDR5 slot until the retaining clips click. A 64-bit operating system is required to address more than 4 GB. Mixing with slower modules forces the whole system down to the lowest common speed.

Questions about this item

What does the 4400MHz speed mean once the module is installed in a real machine?

The module runs at 4400MHz if the platform supports DDR5-4400; otherwise it downclocks to the highest speed the CPU and motherboard allow.

What does the DDR5-35200 (PC5-35200) rating cap in practice?

It sets a peak transfer rate of 35200MB/s, but the actual throughput is limited by the memory controller and motherboard capabilities.

What does the 288-pin DIMM need to fit or mount?

It requires a standard DDR5 288-pin DIMM slot on the motherboard.
