The following comparison statement about UDIMM, RDIM, LRDIMM is correct.
A. UDIMM, unbuffered dual in-line memory module, the address and control signals go directly to the DRAM chip on the DIM without the buffer, so the price is cheap
B. RDIM supports But fered mode and high-performance Registerd mode is more stable than UDIM, and supports the maximum capacity of server memory,
C. UDIMM needs to ensure that the transmission distance between the CPU and each memory particle is equal, so that parallel transmission is effective, and this requires a higher manufacturing process, so UDIMM is lower in capacity and frequency
D. Compared with RDIMM
