PC36400

PC36400 refers to a specific type of DDR3 SDRAM memory module. The "PC" designation indicates a PC (Personal Computer) memory module. The number "36400" is a performance rating, representing the theoretical maximum data transfer rate in megabytes per second (MB/s). Specifically, it signifies a transfer rate of 36,400 MB/s. This is derived from the memory's clock speed and its data bus width. DDR3 memory operates on a 64-bit data bus, and PC36400 corresponds to a memory clock speed of approximately 1800 MHz, with each clock cycle transferring data twice (Double Data Rate). Therefore, 1800 MHz * 8 bytes (64 bits) * 2 = 28,800 MB/s. The rating system for PC memory sometimes uses a different calculation. The PC3 rating for DDR3 implies a peak transfer rate achieved by multiplying the DDR data rate by 8. So, a DDR3-1800 module would be rated as PC3-14400 (1800 x 8 = 14400). However, PC36400 is a less common or potentially an alternative nomenclature for a higher performing DDR3 module, possibly related to a slightly different clock speed or an extended timing. Generally, higher PC numbers indicate faster memory. Compatibility with PC36400 memory would depend on the motherboard and CPU, which must support DDR3 modules operating at the corresponding speeds and timings.
