SK0-003 · Question #750
A technician is replacing memory in a server whose motherboard supports PC3-8500 memory. This type of memory is also known as which of the following?
The correct answer is C. DDR3. PC3-8500 memory is a standard designation for DDR3 (Double Data Rate 3) SDRAM modules. The 'PC3-' prefix explicitly indicates that it belongs to the DDR3 generation of memory.

Why each option
PC3-8500 memory is a standard designation for DDR3 (Double Data Rate 3) SDRAM modules. The 'PC3-' prefix explicitly indicates that it belongs to the DDR3 generation of memory.
SDRAM is a general classification for synchronous dynamic RAM, and DDR3 is a specific, advanced generation within that category, not simply generic SDRAM.
DDR (DDR1) memory is identified by the 'PCxxxx' notation without a generational prefix, such as PC2100, not PC3-8500.
PC3-8500 is the nomenclature for DDR3-1066 memory, indicating a maximum transfer rate of 8.5 GB/s. The 'PC3-' prefix is specifically used to identify DDR3 SDRAM, which offers improvements over its predecessors like higher bandwidth, lower power consumption, and enhanced data integrity.
DDR2 memory is identified by the 'PC2-' prefix, such as PC2-5300 or PC2-6400, not PC3-8500.
Concept tested: Memory type identification - DDR3 SDRAM
