RAM Configuration Optimizer

Estimate how much memory you need and plan a desktop upgrade.

Build your memory plan

Your current system

Choose the DDR4 or DDR5 version that matches your board. An unlisted system needs a manual compatibility check.

For a new build, enter 0 GB and choose 0 sticks.

Your workload and budget

Use a target based on your apps or measured workload, including room for apps you run together.

Your upgrade plan at a glance

Use the capacity result as a starting point, then confirm the kit in your board's manual. This planner cannot detect your hardware, test stability, or promise a frame-rate gain.

Have an app's RAM requirement already? Use the form's capacity target to replace the preset estimate. Calculations run in your browser.

For desktops with replaceable memory. Have your motherboard model and manual ready.

How the capacity estimate is built

These are this tool's planning defaults, not tested requirements: 8 GB for office work; 16 GB for gaming or development; 32 GB for streaming, editing, or virtual machines; and 64 GB for 3D work.

Multitasking adds 0%, 25%, 50%, or 100%. The planner rounds up to 8, 16, 32, 64, or 128 GB and keeps a higher installed capacity. For a new DDR5 kit, it starts at 16 GB. Other kit sizes are outside this simplified model.

Check the requirements for the software you actually use. For example, Adobe's Premiere requirements recommend 16 GB for HD media and at least 32 GB for 4K on Windows. Your own target replaces the preset calculation.

Check the kit before you buy

Confirm the board and module type

Find your exact board on the maker's support site. Check its manual and qualified vendor list (QVL), which lists tested memory kits. Match the memory generation and module type as well as capacity. Kingston's memory setup guide explains why the CPU, module ranks, and number of installed sticks affect support.

Check slots before assuming channel mode

Slots and channels are different. Two sticks must sit in the correct slots to use both channels on a typical desktop. Follow the board's installation order in the guide above. Workstations need extra care: AMD's Threadripper platform guide lists four memory channels for TRX50 and eight for WRX90.

When replacing RAM, compare a complete matched kit. Adding another kit is not a guaranteed match, even with the same part number. See Kingston's kit compatibility advice before reusing or mixing modules.

Choose a supported speed

Use your exact CPU and board specifications to choose a data rate in MT/s. A family name alone cannot confirm it. The memory setup guide above includes speed tables for different module layouts.

Intel XMP profiles are memory overclocking settings, not a promise that any kit will run at its listed speed. Check platform support before changing them in your BIOS.
