Samsung M323R4GA3PB0-CWMOL 32GB Review
Samsung M323R4GA3PB0-CWMOL is a 32GB DDR5-5600 UDIMM, functionally the same tier as Samsung's other M323 32GB desktop tray parts.
32GB, DDR5-5600, and 2Rx8 all decode from the part number's M323 UDIMM convention. CAS latency and overclock support aren't published, this is an OEM tray part, not a retail-boxed kit.
What we can and can't verify
M323R4GA3 maps to 32GB/2Rx8 in Samsung's UDIMM family, with the PB0-CWMOL suffix corresponding to the 5600MT/s bin. No confirmed CAS latency or XMP/EXPO profile.
Compatibility
Standard 288-pin desktop DIMM; runs at JEDEC DDR5-5600 on any current Intel or AMD board.
Comparison to Alternatives
Functionally interchangeable with Samsung's other 32GB DDR5-5600 UDIMM tray parts (M323R4GA3DB0-CWMOD) in this catalog, differing mainly in packaging/date-code suffix rather than spec.
