NEMIX RAM
16 GB DDR4 3200 UDIMM module with CL22 timing for compatible Samsung desktop PCs
This NEMIX RAM module adds 16GB of DDR4 3200 memory to compatible Samsung desktop systems. It uses a 288-pin UDIMM form factor with a 1Rx8 rank configuration. The module runs at 1.20V with a CAS latency of CL22 and has no heat spreader. It is sold new as a single 16GB stick.
This upgrade suits users who have verified their Samsung desktop accepts PC4-25600 non-ECC unbuffered UDIMMs. It is not for builders needing ECC error correction or registered modules for server boards. Buyers whose systems require a different voltage, pin count, or DDR generation should look elsewhere. Systems that only support lower speeds will not gain the rated 3200MT/s.
The decisive figure is the PC4-25600 CL22 1Rx8 rating at 1.20V on a 288-pin UDIMM. Match this exact speed grade, latency, rank, voltage, and pin layout against the motherboard manual or Samsung service documentation before purchase. A mismatch in any of these parameters will prevent the module from functioning correctly.

Yes, the module uses the 288-pin DDR4 UDIMM form factor that matches any desktop motherboard slot wired for DDR4 memory.
Align the notch with the slot key, press straight down until both retention clips click, then verify in BIOS that the capacity shows 16 GB at 3200 MT/s.
No firmware is involved; the memory is a passive component and only requires replacement if a hardware fault develops.
