Memory - RAM

Random Access Memory (RAM) is where data the CPU is working with is temporarily stored. More RAM is generally better, although there are diminishing returns above 16GB for consumer PC, while 32-bit versions of Windows only support a maximum of 4GB. Speed, measured in MHz, is another consideration, as is latency, but most importantly memory needs to be compatible with your motherboard: it'll either be DDR, DDR2, DDR3 or DDR4, and modern AMD- and Intel-based PCs use DDR4 memory alone. Smaller SODIMM modules for laptops and mini PCs and ECC registered memory for servers are all available in this category.

DDR4 Single/Dual Channel 2400MHz 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-channelmodes. 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, Intel Skylake & AMD RYZEN, 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 2,400MHz.

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 Quad Channel 2800MHz+ 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 high-end kits, with a speed of at least 2,800MHz.

DDR SO-DIMM 400MHz RAM Memory Kits

SO-DIMMs are a smaller alternative to a DIMM, being roughly half the size of regular DIMMs. SO-DIMMS are often used in systems which have space restrictions such as notebooks, small footprint PCs such as those with a Mini-ITX motherboard and high-end upgradable office printers.

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.

RAM Memory Coolers

High-end memory modules can be overclocked to deliver extra speed. If you fancy ramping up your RAM, coolers like these will improve heat dissipation and prevent turbo-charged chips from overheating. They look fantastic, too, so they're useful if you're going for a particular aesthetic in your latest PC build.
