Qnap RAM-4GDR4A1-UD-2400 4GB DDR4 2400MHz UDIMM

SKU CH-11NX-WZCD8

4GB DDR4 desktop module running at 2400MHz with CL17 latency and 1.20V operation

  • 4 GB capacity adds responsive multitasking headroom
  • DDR4 at 2400 MHz delivers fast data throughput
  • Low 1.20 V operation reduces system power draw
  • CL17 latency keeps access times tight
  • 288-pin UDIMM fits standard desktop slots

Capacity and fit

This single 4 GB DDR4 UDIMM runs at 2400 MHz with CL17 latency and 1.20 V operation. The 288-pin DIMM follows the PC4-19200 standard and uses non-ECC unbuffered signal processing. It suits desktop systems that accept standard DDR4 memory in a single-channel or dual-channel layout.

Sustained load behaviour

The module operates at its rated 2400 MHz without overclocking headroom, so throughput remains steady during long workloads. Non-ECC unbuffered design means the memory controller handles refresh cycles directly, which is typical for consumer desktop platforms. Thermal output stays modest at the standard 1.20 V level.

Compatibility checklist

Verify that the motherboard supports DDR4 UDIMMs at 2400 MHz and can run non-ECC unbuffered modules. Confirm an available 288-pin DIMM slot and that the BIOS recognises PC4-19200 speeds. Systems limited to lower speeds will downclock the module automatically.

Questions about this item

How much power does the 1.20 V DDR4 module draw when the system runs all day?

The module operates at 1.20 V, which is the standard DDR4 voltage, keeping power draw and heat low during continuous use.

What motherboard slot is required for this 288-pin UDIMM to work?

It needs a standard DDR4 DIMM slot that accepts 288-pin unbuffered non-ECC memory.

Will the CL17 2400 MHz stick run stably alongside older DDR4 modules in the same board?

The motherboard will clock all installed DDR4 to the lowest common speed and latency, so this CL17 2400 MHz module will down-clock to match slower sticks.
