The third most important feature when building a gaming pc. To put it simple, the more the better! Faster RAM is also defined by its frequency where higher is better.

When looking for RAM consider the model too. Manufacturers often build systems with either unbranded RAM (this translates to cheap Far East junk!) or the bottom end range of a brand; Corsair do basic ram designed for basic budget systems and it is just known as Corsair Value RAM, but they also do an LPX Range which is far better. We only use Corsair LPX DDR4 RAM or better here, its regarded the best in the industry and has been for years. Corsair also offer a lifetime warranty with all of their LPX RAM.

It is also worth noting that we use the correct channel configuration - For example if you choose 8GB we would use 2 x 4GB modules so that it operates in dual channel as it should. Many system builders would use a single, and cheaper, 8GB module which means the RAM would only operate single channel mode which will impact the performance by as much as 35%!. All RAM nowadays runs in either Dual or Quad channel meaning it must be configured in equally split module sizes of 2GB, 4GB, 8GB, 32GB, 64GB, 128GB etc, any other configuration is incorrect.

How much RAM will depend on the task in hand - for basic tasks such as browsing, word processing and emails 2-4GB is enough. Older PC games require 4GB of RAM, whilst the newer, higher end titles will demand 8GB or 16GB to ensure they run in all their glory. Multimedia editing and CAD workstations will ideally want 16GB or 32GB.

Now you know how much RAM you need, how fast does it need to be? RAM speed is defined by frequency, with current DDR4 Modules they start at 2133Mhz and go all the way to 5333Mhz. The sweet spot for intel based systems is 2400Mhz - 3200Mhz whilst AMD based systems is between 3000Mhz - 3600Mhz, anything north of these numbers offers barely any real world performance increase, so much so we don't even list anything faster than 3600Mhz as its just a waste of money. At the same time we don't list anything below 3000Mhz as the small performance bump between lower speeds and 3000Mhz isn't worth the cost saving. 3000Mhz is the perfect sweet spot for gamers, whilst workstation users and multimedia creators and streamers should look to the faster 3200Mhz and 3600Mhz options.
