A-Tech 16GB DDR5 4800 Desktop Memory

This 16GB DDR5 module runs at 4800MHz with a CL40 latency and standard 1.10V operation. It uses unbuffered, non-ECC chips from major brands and fits any desktop motherboard with a 288-pin DDR5 slot. The single stick adds capacity for everyday workloads and multitasking.

Build fit: 288-pin DDR5 DIMM, 1.10V standard voltage

Installation requires a motherboard with DDR5 slots; the module draws power at the standard 1.10V so no manual voltage adjustment is needed. As an unbuffered DIMM it works directly with the memory controller, leaving all remaining slots free for future expansion up to your board's limit.

Suits mainstream AMD and Intel desktop upgrades

Ideal for users replacing a failed stick or adding 16GB to a compatible DDR5 system who want tested major-brand chips and a direct Kingston KVR48U40BS8-16 equivalent. Builders needing ECC, registered modules, higher frequencies or lower latencies should consider other kits.

Questions about this item

Will the CL40 latency hold back performance during long rendering jobs?

CL40 is the rated CAS latency at 4800 MT/s; the module runs at 1.1 V with standard JEDEC timings, so latency stays consistent under sustained load.

Does the stick run hot or noisy when the system is on all day?

The DIMM operates at the DDR5 standard 1.1 V with no onboard fan, so it adds minimal heat and makes no noise of its own.

What motherboard slot is required for this 288-pin DDR5 module?

A desktop DDR5 DIMM slot (288-pin) is needed; the board must support DDR5 4800 unbuffered non-ECC memory.
