8GB DDR5 4800 SODIMM upgrade

This 8GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1 V operation. The 262-pin SO-DIMM form factor fits laptops, all-in-one PCs and compatible NAS units. It is an unbuffered, non-ECC design built to JEDEC PC5-38400 specifications.

JEDEC-standard compliance and DIY fit

The module meets full JEDEC and RoHS standards, so it preserves the original system warranty when installed. No heat spreader is fitted, keeping the profile low for tight chassis. Installation is a straightforward user upgrade in most supported devices.

Suits owners of Kingston KVR48S40BS6-8 compatible

Buyers needing a direct 8GB replacement for that Kingston part number will find matching speed, voltage and pin-out. Systems requiring ECC, registered DIMMs, higher capacities or faster DDR5 speeds should look at other modules.

Questions about this item

Does the 8 GB DDR5 4800 CL40 SODIMM need any firmware updates or periodic re-seating to stay reliable?

No firmware is involved; the module follows JEDEC DDR5 4800 specifications and is validated for continuous operation in laptops, all-in-ones and NAS units.

What is the first limit reached when the 262-pin 1.1 V module runs at full 4800 MT/s for hours?

The CL40 latency and single-rank 1Rx16 organisation set the throughput ceiling; the JEDEC-standard voltage and unbuffered design keep power draw stable.

How much heat or fan noise does the 8 GB DDR5 stick add when the laptop runs all day?

The module has no heat spreader and operates at the standard 1.1 V, so thermal output stays within the laptop’s existing cooling envelope.
