Single vs. Dual-Rank RAM: Which Memory Type Will Boost Performance?

Today, we’ll compare single and dual-rank RAM to help you ‌understand the difference between these two types of RAM, how to identify them, and which one is best for you.

Single-Rank RAM

What is it? Configuration of random access memory (RAM) Primary Use: Storage of temporary system files Initial Release: 1990s Influential Developers: JEDEC Crucial Technologies Influenced: DRAM IC Chips

Dual-Rank RAM

What is it? Configuration of random access memory (RAM) Primary Use: Storage of temporary system files Initial Release: 1990s Influential Developers: JEDEC Crucial, HP, Micron, Timetec Technologies Influenced: DDR, DDR2, DDR3, or DDR4

Single vs. Dual-Rank RAM: Similarities

– Single and dual-rank RAM are both composed of DRAM chips on a DIMM (RAM stick). – JEDEC standardizes both memory formats. – Single and dual-rank RAM are both used as volatile memory for the normal function of a contemporary computer or laptop.

Single vs. Dual-Rank RAM: Differences

– Single-rank RAM comprises a single set of memory chips in the RAM module.  – Single-rank RAM has lower energy consumption than dual-rank RAM. – Single-rank RAM has lower heat emissions than dual-rank RAM.
