Kit composition and purpose

This kit contains two 16GB DDR5 modules rated at 4800MHz with CL40 timings and 1.1V operation. It is intended for desktop systems that accept 288-pin unbuffered non-ECC DIMMs and need a matched pair for dual-channel operation.

Who should consider this and who should not

Builders upgrading a platform that supports DDR5-4800 and wants a factory-matched 2Rx8 kit will find this suitable. Buyers whose motherboards require ECC, registered modules, or a different DDR generation cannot use these DIMMs.

Deciding specification

The modules run at DDR5-4800 (PC5-38400) with a CAS latency of 40 and a timing string of 40-40-40-96 at 1.1V; if your CPU or board cannot operate at this speed and voltage combination, the memory will not perform as specified.

Questions about this item

Will the 1.1 V DDR5 modules run hot or draw extra power if I leave the system on all day?

The kit is rated at 1.1 V with standard DDR5 timings; it operates at the normal voltage for DDR5-4800 and does not require additional cooling beyond typical case airflow.

My motherboard has 288-pin DDR5 slots — is that the only thing I need to install this 2x16 GB kit?

Yes, the modules are 288-pin non-ECC unbuffered DIMMs; a 64-bit operating system is also required to use more than 4 GB of memory.

If I keep my existing DDR5 modules and add this 4800 MHz CL40 kit, what speed will the memory run at?

All installed memory will run at the slowest performance of the modules or the CPU capability, so mixing speeds or timings will drop everything to the lowest common setting.
