SKU CH-PYJ3-WSAHB

A 16 GB DDR5 desktop DIMM running at 5600 MHz with CL40 latency and 1.10 V operation

  • Capacity16GB
  • SpeedDDR5 5600 (PC5 44800)
  • Tested Frequency5600
  • CAS LatencyCL40
  • Voltage1.10V
  • ECCNo
  • 16 GB DDR5 capacity lets you run more apps at once
  • 5600 MT/s rated speed moves data quickly through the system
  • CL40 CAS latency keeps response times tight
  • 10 V standard voltage runs efficiently without extra power
  • 288-pin DIMM form factor fits standard desktop memory slots

Capacity and Purpose

This 16 GB DDR5 module is an unbuffered DIMM built to replace the Hynix HMCG78AGBUA part. It targets desktop owners who need a straightforward memory upgrade for everyday workloads and multitasking.

Sustained-Load Behaviour

Running at the standard 1.10 V, the stick maintains its rated 5600 MT/s without a heat spreader, so thermals depend on case airflow during long sessions. The CL40 timing stays consistent as the module settles into extended use.

Interface Practical Limits

The 288-pin DDR5 interface tops out at the PC5-44800 bandwidth ceiling, so this module cannot exceed the 5600 MT/s data rate. Any higher speed would require a different memory standard or an overclockable kit not supplied here.

商品問答

How hot and loud does the 1.10V DDR5-5600 module run under continuous load?

The stick runs at the standard 1.10 V DDR5 voltage with no heat spreader, so it stays cool and silent; any warmth or fan noise comes from the motherboard and case airflow around the DIMM slot.

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

A desktop board with a DDR5 288-pin slot, support for 5600 MT/s operation, and a BIOS that can train non-ECC unbuffered memory at 1.10 V.

Will this CL40 5600 MHz stick downclock cleanly beside my older DDR5-4800 modules?

Yes — the JEDEC DDR5 spec requires backward compatibility, so the module will automatically run at the lowest common speed and latency present in the system.
