A-Tech 16GB DDR5-4800 Desktop RAM Module

SKU CH-B9H7-N7NHE

16GB DDR5-4800 desktop DIMM with CL40 latency and 1.1V operation for compatible Patriot system upgrades

  • Total capacity16 GB
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor Brand DRAM IC Chips
  • CAS latency40
  • Tested speed4800
  • Rated voltage1.1 V
  • 16GB DDR5 memory boosts multitasking capacity
  • 4800MHz speed accelerates data throughput for responsive performance
  • 1V operation reduces power draw and heat output
  • 288-pin DIMM fits standard desktop motherboard slots
  • Tested with major-brand DRAM ICs for reliable operation

Purpose and Fit

This 16GB DDR5-4800 desktop DIMM is built as a direct replacement for Patriot modules PSD532G4800K, PSD516G48002 and PSD516G480081. It uses major-brand DRAM ICs and runs at the standard 1.10V DDR5 voltage. The unbuffered, non-ECC design suits mainstream desktop motherboards that accept 288-pin DDR5 memory.

Who Should Buy

System builders upgrading a desktop that originally shipped with the listed Patriot parts will find the same 4800MT/s speed and CL40 latency. Users who need ECC error correction, registered buffering or a heat spreader should look at modules that explicitly include those features.

Deciding Specification

The single figure that determines compatibility is the tested frequency of 4800MT/s combined with the 1.10V operating voltage; your platform must support DDR5 at this exact data rate and voltage for the module to function as specified.

Questions about this item

How much heat and power does this 1.10 V DDR5 module add when the system runs all day?

The module operates at the standard DDR5 voltage of 1.10 V and has no heat spreader, so it relies on normal case airflow to stay cool during continuous use.

What must my motherboard provide for this 288-pin DDR5 DIMM to work?

Your motherboard needs a DDR5-compatible 288-pin DIMM slot and a CPU or chipset that supports DDR5 4800 memory.

Will this 1Rx8 DDR5 stick run alongside my existing DDR5 modules at 4800 MHz?

Yes, it is a 1Rx8 non-ECC unbuffered DIMM rated for 4800 MHz, so it will match other DDR5 4800 modules and the system will run all sticks at that speed.
