Memory - RAM

RAM (Random Access Memory) is where data the CPU is working with is temporarily stored. More RAM is generally better, although there are diminishing returns and 32-bit versions of Windows only support a maximum of 4GB. Speed, measured in MHz, is another consideration, but most importantly memory needs to be compatible with your motherboard: it'll either be DDR, DDR2, DDR3 or DDR4. Smaller SODIMM modules for laptops and mini PCs and ECC memory for servers are all available in this category.

DDR4 Single/Dual Channel 2666MHz+ RAM Memory Kits

DDR4 SDRAM is the fastest and most efficient consumer memory available. It's compatible with Intel's Broadwell-E which run in quad-channel and Kaby Lake & Skylake CPUs which run in dual-channel modes. It is also compatible with AMD's latest RYZEN CPUs running in a dual-channel configuration. The modules found here are designed for Intel Kaby Lake & Skylake, so they're sold in matching kits of two modules for best performance or single modules for a cheap upgrade. These are the mid-range kits, with a speed of at least 2,666MHz.

DDR4 Single/Dual Channel 3000MHz+ RAM Memory Kits

DDR4 SDRAM is the fastest and most efficient consumer memory available. It's compatible with Intel's Broadwell-E which run in quad-channel and Kaby Lake & Skylake CPUs which run in dual-channel modes. It is also compatible with AMD's latest RYZEN CPUs running in a dual-channel configuration. The modules found here are designed for Intel Kaby Lake & Skylake, so they're sold in matching kits of two modules for best performance or single modules for a cheap upgrade. These are the high-end kits, with a speed of at least 3,000Hz.

DDR4 Quad Channel 2666MHz RAM Memory Kits

DDR4 SDRAM is the fastest and most efficient consumer memory available. It's compatible with Intel's Broadwell-E which run in quad-channel and Kaby Lake & Skylake CPUs which run in dual-channel modes. It is also compatible with AMD's latest RYZEN CPUs running in a dual-channel configuration. The modules found here are intended for use with Intel Broadwell-E or Haswell-E CPUs, using an Intel X99 motherboard which runs in quad-channel mode. That's what these modules are designed for, so they're sold in matching kits of four or eight. These are the mid-range kits, with a speed of 2,666MHz.

DDR4 Quad Channel 3200MHz+ RAM Memory Kits

DDR4 SDRAM is the fastest and most efficient consumer memory available. It's compatible with Intel's Broadwell-E which run in quad-channel and Kaby Lake & Skylake CPUs which run in dual-channel modes. It is also compatible with AMD's latest RYZEN CPUs running in a dual-channel configuration. The modules found here are intended for use with Intel Broadwell-E or Haswell-E CPUs, using an Intel X99 motherboard which runs in quad-channel mode. That's what these modules are designed for, so they're sold in matching kits of four or eight. These are fast premium kits with speeds of at least 3200MHz.

DDR3 Single/Dual Channel 1800MHz+ RAM Memory Kits

DDR3 memory is the most common memory. Excluding Intel X99, all current generation Intel and AMD desktop chipsets (and many previous generations too) use it. These high-end kits range from 4GB to 16GB with speeds from 1,866MHz to 3,000MHz – you may need to enabled the memory's XMP (Extreme Memory Profile) in your motherboard's BIOS to run it at full speed. Each kit has two identical sticks – they're designed for motherboards with just two slots or with four slots that need to be filled in pairs.

DDR2 Single/Dual Channel 533MHz+ RAM Memory Kits

Like DDR, DDR2 is a type of SDRAM in which data is sent on both the rising and falling edges of clock cycles in a data burst. DDR2 is the next evolutionary step in the DDR infrastructure and has additional features built into it to allow for increased system performance. This memory is designed for users which require faster memory however with still a budget in mind therefore is the mainstream choice for mid range systems.

Server DDR3 1600MHz RAM Memory Kits

Available as regular DIMMs or SO-DIMMs for micro-servers, these DDR3 modules are designed for servers and are engineered and clocked to provide rock solid stability 24/7. ECC (error correcting code) modules are immune to errors, while registered/buffered sticks reduce memory controller load and ensure additional stability when using many modules together. Motherboards need to support ECC and registered memory for these features to work.
