The Vostro™ 3360 / Vostro™ 3460 / Vostro™ 3560 system supports dual-channel DDR3 SDRAM with memory speeds of 1333 MHz and 1600MHz. The memory offers a significant increase of memory performance over previous platforms.
The memory solution is implemented in a dual-channel configuration, allowing the system to have twice the memory bandwidth while using the same memory technology.
Memory modules must be installed as a perfectly matched pair to take advantage of the dual-channel memory bus. If not a matched pair, the system's memory bus operates in a single-channel configuration.
Vostro™ 3360 / Vostro™ 3460 / Vostro™ 3560 has two user-accessibleSODIMM (Small Outline Dual In-Line Memory Module) sockets, both slots can be accessed after removing the base cover. Basically, when both DIMM connectors are populated, the system has optimum dual-channel performance unless channels A and B have different amounts of memory.
SODIMM (small outline dual in-line memory module) is a smaller and more compact form of RAM intended for laptops. In comparison, the larger DIMM RAM is found in desktop computers
SDRAM(Synchronous dynamic random access memory) is a type of RAM technology in how it communicates with the rest of the computer in that it synchronizes with the system bus. All modern desktops, laptops, and netbooks use a form of SDRAM (DDR).
