A-Tech 8GB DDR4 2400 CL17 1.20V Desktop RAM

SKU CH-HCDW-TB6T0

8GB DDR4 2400 CL17 1.20V desktop DIMM memory module for system upgrades

  • Capacity8GB
  • SpeedDDR4 2400 (PC4 19200)
  • Tested Frequency2400
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCNo
  • 8GB capacity lets you run more apps at once
  • 2400 MHz DDR4 speed keeps data flowing to the CPU
  • CL17 latency reduces wait cycles for snappier response
  • 20 V operation cuts power draw and heat
  • 288-pin unbuffered DIMM fits standard desktop slots

What This Memory Is

This A-Tech module is an 8 GB DDR4 desktop DIMM built as a direct replacement for the Crucial BLS8G4D240FSEK. It installs in standard 288-pin slots and runs at the JEDEC-standard 1.20 V.

The Deciding Specification

The module operates at DDR4 2400 with a CAS latency of CL17. If your board or existing memory requires a different speed or latency, this stick will not match the required timing.

Who Should Buy It

Choose this kit when you need a single 8 GB non-ECC unbuffered DIMM to replace a failed Crucial module or to add capacity to a system that supports DDR4 2400 CL17. Skip it if your platform demands ECC, registered memory, a higher frequency or a lower latency.

Questions about this item

Will this 288-pin DDR4 module fit a desktop motherboard that requires 2400 MHz unbuffered memory?

Yes. The stick is a 288-pin DDR4 DIMM rated at 2400 MHz (PC4-19200) with CL17 latency and 1.20 V operation, matching standard desktop DDR4 slots that accept unbuffered non-ECC memory at that speed.

Does the lack of a heat spreader affect reliability or thermal performance in a typical desktop case?

No. The module runs at the standard 1.20 V DDR4 voltage without a spreader; in normal desktop airflow the components stay within safe temperatures and the maker’s testing covers continuous operation at the rated 2400 MHz CL17 specification.

Can I add this single 8 GB stick alongside an existing 8 GB module to run dual-channel?

Dual-channel will work if the second module is also an 8 GB DDR4 2400 MHz CL17 1.20 V unbuffered DIMM; matching capacity, speed, latency and voltage lets the memory controller interleave the two sticks.
