Additionally, the price for high-frequency RAM tends to ramp up very quickly. So, generally speaking, a higher frequency is better, but note that some CPUs and motherboards may not support some frequencies effectively, and may require additional research if you’re looking to maximize your performance. DDR4-3200 is referring to a 3200MHz frequency cycle, which translates to about 3.2 billion read/write cycles per second. Your memory is constantly doing reading and writing cycles with your currently loaded data, and that frequency is referring to how many times per second the memory is going through that cycle. Those four-digit numbers are the frequency of the RAM. When looking at RAM products, you might find it listed as DDR4-3200 or DDR4 2666 MHz. There are two main factors behind what makes RAM considered fast: frequency and timing.įirst is the RAM’s frequency, which is far too commonly referred to as the speed. This is the aspect of RAM that gets a bit complex. As mentioned above, you’ll want to refer to your CPU and motherboard specifications to determine what RAM capacity your system can handle-then following the edict of “more is better” aim for the higher end of that spec. Most modern systems are 64-bit, which can theoretically handle up to 4 petabytes of memory, albeit most modern PC CPUs tend to be capped at anywhere between 32GB and 256GB of memory. A 32-bit process and operating system could only make use of up to 4GB of memory, so the additional RAM on such a system effectively goes to waste. You cannot just purchase as much RAM as possible, however. Various software will have their own minimum requirements for available memory. Video games will include RAM capacity in their recommended system requirements. Generally, having 8GB of RAM will provide a better computing experience than 4GB of RAM. RAM capacity is the major specification folks are looking for when purchasing. This is the part many people are familiar with: More RAM is good, less RAM is bad. Whatever the case, though, your motherboard and CPU are going to be the major determining factors on what kind of DDR RAM you need for your PC, so know those specifications before choosing your RAM. DDR5 does exist as a memory standard, and you may find it mentioned in graphics cards, but DDR5 RAM modules aren’t quite ready for the market at the time of writing this article. From there came DDR2, then DDR3, and now most current devices utilize DDR4 RAM.
