A desktop technician is servicing hardware for a creative design firm and needs to upgrade memory across both laptop mobile workstations and desktop systems. Which TWO of the following statements correctly identify key RAM form factors and dual-channel installation rules for these platforms?
- Mobile workstations utilize SO-DIMM modules, which have a smaller physical footprint and distinct pin keying compared to desktop DIMMs.Answer
- To achieve dual-channel memory performance on desktop motherboards, matching modules must be installed into designated slot pairs according to motherboard specifications.Answer
- CStandard full-sized desktop DIMM modules can be installed into laptop expansion slots as long as the memory generation and operating voltage match.
- DDual-channel memory throughput is automatically enabled whenever two RAM modules are placed side-by-side in adjacent motherboard slots.
Answer
The statement that mobile workstations utilize SO-DIMM modules with a smaller physical footprint, and the statement that dual-channel performance requires installing matching modules into designated slot pairs, are both correct.
Mobile workstations require SO-DIMM modules due to compact physical dimensions. For dual-channel operation, motherboard manufacturers require installing identical memory sticks into specific channel-separated slots, which provides twice the bus bandwidth compared to single-channel mode.
