Compatible MSI Notebook Upgrade

This 4 GB DDR4 SO-DIMM module is built for MSI GL62M 7REX, GL62MVR 7RFX, GL72 6QE, GL72 7QF, GL72 7RD and GL72 7RDX notebooks. It targets owners of those specific laptops who need a straightforward capacity increase without compatibility guesswork.

Single Slot 260 Pin DDR4 Module

The stick occupies one of the two available SO-DIMM sockets and runs at 2400 MHz with CL17 timing at 1.2 V. It leaves the second socket free for a matching module, allowing the platform to reach its 32 GB maximum when paired correctly.

Low Voltage Unbuffered Operation

As an unbuffered non-ECC module without a heat spreader, it draws minimal power and produces no audible noise inside the notebook chassis. The 1.2 V DDR4 standard keeps thermals in line with the original system design during typical workloads.

Questions about this item

How does the CL17 latency affect performance during long workloads?

CL17 timing of 17-17-17 sets the access delay; all installed memory runs at the slowest module speed, so sustained throughput depends on matching kits.

Does the module run hot or draw extra power in an MSI GL72 notebook all day?

Rated at 1.2 V with no heat spreader, the unbuffered DDR4 SO-DIMM stays within standard notebook thermal and power envelopes during continuous use.

Which MSI notebook models must I already own for this 4 GB stick to work?

Compatible systems are the MSI GL62M 7REX, GL62MVR 7RFX, GL72 6QE, GL72 7QF, GL72 7RD and GL72 7RDX.
