FAQs

  • UDIMM (Unbuffered DIMM) is a 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.
  • UDIMM is an unregistered memory, while DIMM or RDIMM is a registered or buffered memory. DIMMs have an additional buffer between the memory controller and DRAM. So, UDIMM offers faster performance at affordable rates at the cost of stability.
  • RDIMMs are typically faster. This permits each memory channel to utilize up to three dual-rank DIMMs, greatly increasing the amount of memory the server can support. With RDIMMs, the partial buffering slightly increases both power consumption and memory latency.
  • A motherboard is designed to support either an RDIMMs or a UDIMM. However, not both since these two DIMMs have different architectures. Using both won’t harm the system, but it will be unusable. The system will show an error once the motherboard detects an incompatible memory installed and will only function again once you put in the correct memory module.
  • No, it can't be compatible at all. If your motherboard doesn't support registered memory then you can't use it.
  • Although two RAM form factors use the same technology and functionally work the same way, they cannot be mixed. The UDIMM stick cannot be fitted into the SODIMM slot and vice versa
