Memory - RAM

Not sure how much RAM you need? Read our Memory Buying Guide

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.

DDR5 Single/Dual Channel 4800MHz+ RAM Memory Kits

DDR5 SDRAM is the fastest and most efficient consumer memory available. It's compatible with Intel's 12th gen Core Alder Lake processors. The modules found here are designed for dual-channel configurations and include two modules for best performance or single modules for a cheap upgrade.


Server DDR4 2666MHz RAM Memory Kits

DDR4 server memory brings maximum speed and efficiency to Intel's six-channel Xeon Scalable platform.

Server memory is designed to have 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. These particular modules are rated up to 2666MHz.
