8GB DDR5 4800 Desktop Module

This 8GB DDR5 4800 module is built as a direct replacement for the Samsung M323R1GB4BB0-CQK part. It fits standard 288-pin DIMM slots and runs at the JEDEC standard 1.10V. The single-rank 1Rx16 organisation keeps the design simple for desktop boards that accept unbuffered non-ECC memory. Users who need a straightforward capacity increase without overclocking will find it matches the original specification.

Thermals noise and power draw

Operating at the standard 1.10V DDR5 voltage, the module draws only the power required for its 4800 MT/s data rate. With no heat spreader attached, the bare PCB relies on normal case airflow to stay within thermal limits. The low voltage and lack of active cooling mean acoustic contribution is effectively zero in a typical chassis. Power consumption scales with workload but remains consistent with the DDR5 baseline for this density.

Samsung chipset and validated compatibility

The Samsung chipset on the PCB is the same component used in the original M323R1GB4BB0-CQK, so electrical behaviour matches the OEM part. A-Tech tests every module at 4800 MT/s with CL40 latency before shipping, confirming signal integrity at the rated speed. The validation process replaces the need for separate driver or firmware packages; the board simply recognises the SPD data and configures itself. No extra software or accessories are bundled because the memory is a self-contained hardware upgrade.

Questions sur cet article

How do I install this 288-pin DDR5 DIMM and which step is commonly missed?

Align the notch on the module with the key in the slot, press down firmly until both side clips snap shut, then verify in BIOS that the 4800 MT/s speed is active — many builders forget to enable the XMP or EXPO profile.

What maintenance or replacement will this 8 GB DDR5 module need over time?

No scheduled maintenance is required; keep the contacts clean and ensure case airflow stays adequate, and replace the module only if memory diagnostics report errors or capacity becomes insufficient.

What limit appears first when this CL40 1.10 V DDR5 kit runs under sustained load?

The CAS latency of 40 cycles at 4800 MT/s sets the baseline response time, so latency-sensitive workloads hit that timing ceiling before bandwidth or thermal limits become a factor.
