Samsung M425R4GA3BB0-CQKOL 32GB Review
Samsung M425R4GA3BB0-CQKOL is a 32GB DDR5-4800 SODIMM, Samsung's baseline-speed OEM laptop memory part.
Capacity, DDR5-4800 speed, and 2Rx8 rank decode from Samsung's M425 SODIMM naming; the CQKOL suffix is the 4800MT/s bin rather than the faster 5600 bin used on other M425 parts in this catalog. No published CAS latency.
What we can and can't verify
M425R4GA3 decodes to 32GB/2Rx8; CQKOL maps to the JEDEC-baseline 4800MT/s bin rather than the 5600 bin used by the CWMOL/CWMOD suffix parts elsewhere in Samsung's M425 line.
Compatibility
262-pin SODIMM; fits any laptop or mini-PC DDR5 SODIMM slot at JEDEC DDR5-4800 defaults.
Comparison to Alternatives
Against Samsung's own M425R4GA3BB0-CWMOL (same 32GB/2Rx8 SODIMM but DDR5-5600), that part is the faster option if your platform supports the higher speed; this 4800MT/s part is typically the cheaper baseline pick.

Reviewed by Burooj Alam. Rated by us, not by users.
Best for
- Budget 32GB laptop/mini-PC memory upgrades
- Systems that only support baseline DDR5-4800 anyway
Not for
- Buyers wanting the fastest SODIMM speed available
- Desktop systems (this is SODIMM, not a desktop DIMM)
