32 GB is the comfortable amount for a gaming PC in 2026, and 16 GB is the workable minimum. With memory prices where they are (Tom’s Hardware tracked 32 GB DDR5 kits at around $400 in August 2026, with 16 GB kits upwards of $240), the difference between the two is now a real share of the budget. So it’s worth knowing which you actually need rather than buying the bigger number by default.
What system memory does in a game
System memory (RAM) holds what the CPU is working on right now: the game’s code, the world around you, sound, and everything Windows and your other programs are doing. It’s separate from the graphics card’s own memory (VRAM), which holds textures. When RAM runs out, Windows moves data it thinks is idle to the SSD (the page file) and pulls it back when it’s needed. An SSD is far slower than RAM, so you feel that as stutter: short freezes when you turn a corner or load into a new area, even when the average frame rate looks fine.
That’s the key point: too little RAM rarely lowers your average frame rate much. It causes hitches.
16 GB, 32 GB or 64 GB
- 16 GB: enough for most games on their own, and still what many publishers list as recommended. Big open-world and simulation games, with a browser, Discord and a game launcher open, can fill it. Windows 11 itself needs 4 GB minimum, and in practice uses several gigabytes before you start a game.
- 32 GB: room for demanding games plus background apps, streaming or recording software, and mods. It’s the sensible target for a new build if the budget allows.
- 64 GB: for work alongside gaming: video editing, 3D rendering, large photo projects or virtual machines. It won’t raise frame rates in games.
The publisher’s own listing is the most reliable guide for the games you play most. For example, the Battlefield 6 requirements recommend 16 GB for most targets and 32 GB for 4K at 60 fps or 1440p at 144 fps.
If your CPU has integrated graphics
A PC gaming on integrated graphics (such as a Ryzen 8000G) has no VRAM of its own. The graphics borrow part of the system memory, so the same amount of RAM goes less far. 32 GB, or at least a fast two-stick 16 GB kit, matters more on these builds.
Memory speed
Get the amount right first, then the speed. On AMD’s AM5, DDR5-6000 is the usual target; on Intel’s Core Ultra 200S it’s DDR5-6400. Faster kits cost more for small gains in games. Whatever you buy, turn on its XMP or EXPO profile in the BIOS, or it runs at a slower default speed. The details are in DDR4 vs DDR5 and BIOS setup.
Two sticks, not one
Desktop Ryzen and Core CPUs have two memory channels. A single stick uses one channel and halves peak bandwidth, which costs frame rate in CPU-limited games. Buy a two-stick kit and install it in the slots the manual marks for two sticks. On most four-slot boards that’s A2 and B2, the second and fourth slots counting from the CPU.
Why you shouldn’t fill all four slots
Four DDR5 sticks put two on each channel, which is much harder for the memory controller. AMD’s official speed for Ryzen 9000 drops from DDR5-5600 with two sticks to DDR5-3600 with four, and many boards won’t run four sticks at their rated XMP or EXPO speed. So:
- Buy the total you want as a single two-stick kit (2 × 16 GB for 32 GB).
- If you start with 16 GB, plan to replace the kit later rather than add a second one. Mixing kits also causes stability problems, even with identical model numbers.
- If you truly need 64 GB or more, buy 2 × 32 GB, or larger modules, rather than four smaller sticks.
Checking what you’re using
Open Task Manager (Ctrl + Shift + Esc), go to Performance, then Memory, and play for a while with your usual apps open. If “In use” regularly sits near your total and games stutter, more RAM will help. If there are several gigabytes spare, it won’t, and a graphics card or CPU upgrade is the better spend.
