Frequently Asked Questions (FAQs)

1. Is UDIMM the same as RAM?

Short for unbuffered (or unregistered) dual inline memory module, UDIMM is a type of volatile memory chip, used mostly in desktop and laptop computers. It is a conventional type of RAM. Modern DDR memory chips are a type of UDIMM.

2. Is UDIMM memory good?

Reputable. Unbuffered memory (UDIMM) is faster than registered memory. The register in registered memory delays all information transferred by one clock cycle, slowing the overall system performance. Most systems are designed to take either registered or unbuffered memory.

3. What is the difference between DIMM and UDIMM memory?

UDIMM refers to unregistered memory, while DIMM (or RDIMM) refers to registered or buffered memory. DIMMs have an additional buffer between the memory controller and DRAM. As a result, UDIMM offers faster performance at affordable rates at the cost of stability. However, RAM options do not stop with UDIMMs and RDIMMs.

4. Can I use UDIMM in my PC?

The answer to your question is no. UDIMM and DIMM are meant for two different types of motherboards.
