Samsung M323R1GB4PB0-CWMOL 8GB Review
Samsung M323R1GB4PB0-CWMOL is an 8GB DDR5-5600 UDIMM, a genuine Samsung-branded OEM memory stick that ships inside prebuilt desktops and workstations rather than being boxed for retail.
We can confirm the 8GB capacity, DDR5-5600 speed, and 1Rx16 rank layout straight from the Samsung part number, since Samsung's M323 UDIMM naming convention is well documented. What we can't confirm is CAS latency or an XMP/EXPO profile, Samsung doesn't publish either for its OEM tray parts, so treat this as a functional-replacement or system-builder part rather than one you'd tune.
What we can and can't verify
The M323R1GB4PB0 part number decodes cleanly: M323R is Samsung's 288-pin desktop UDIMM DDR5 family, 1GB4 encodes the 8GB/1Rx16 configuration, and the CWMOL suffix maps to a 5600MT/s speed bin. Samsung doesn't publish CAS latency, sub-timings, or an XMP/EXPO profile for this SKU the way it would for a retail-boxed kit.
Compatibility
Standard 288-pin desktop DIMM; runs at JEDEC DDR5-5600 defaults on any current Intel or AMD desktop board. Since there's no confirmed XMP/EXPO profile, don't expect a one-click overclock, it'll simply run at its rated JEDEC speed.
