User Upgradeable: Many laptops and SFF machines have user-accessible memory slots, making it relatively straightforward to upgrade the memory by replacing or adding SODIMMs. Fulton, Jennifer (November 9, 2000). "The complete idiot's guide to upgrading and repairing PCs". Indianapolis, IN: Alpha Books – via Internet Archive. Installing Memory—Laptops and desktops differ in how memory is installed, as you learn in this section. Foundation Topics Memory Upgrade Considerations

Variety of Capacities and Speeds: SODIMMs are available in a range of capacities and speeds, allowing users to choose the memory configuration that best meets their needs. The table below summarises the three common form factors of memory modules used in tech gadgets today: Virtually all memory modules use some type of dynamic RAM ( DRAM) chips. DRAM requires frequent recharges of memory to retain its contents. SRAMDIMMs are often referred to as "single-sided" or " double-sided" to describe whether the DRAM chips are located on one or both sides of the module's printed circuit board (PCB). However, these terms may cause confusion, as the physical layout of the chips does not necessarily relate to how they are logically organized or accessed.

The maximum capacity on commercially available DDR2 DIMMs is 8GB, but chipset support and availability for those DIMMs is sparse and more common 2GB per DIMM are used. [ citation needed] [3] History [ edit ] While DDR SDRAM is sometimes rated inMHz, it is more often rated by throughput (MBps). Common speeds for DDR SDRAM include PC1600 (200MHz/1600Mbps), PC2100 (266MHz/2100Mbps), PC2700 (333MHz/2700Mbps), and PC3200 (400MHz/3200Mbps), but other speeds are available from some vendors.

However, older memory module types such as early 168-pin DIMMs were available with different types of memory chips. You need to specify the right memory chip type in such cases to avoid conflicts with onboard memory and provide stable performance.
