What is UDIMM?
A type of volatile memory chip, unbuffered dual inline memory module, or UDIMM for short is mostly found in desktop and laptop computers. This kind of RAM is traditional. A type of UDIMM is the modern DDR(double data rate) memory chip. In systems where there are just one or two modules per memory channel. UDIMM typically operates quicker than RDIMM(Registered memory). However, UDIMM can improve performance and lower latency on machines that use three or more modules per channel, such as high-end workstations and servers.
