How Much RAM Do You Need in 2026?

Short answer: 32GB for a new gaming PC. 16GB works on a tight budget if your graphics card has plenty of its own memory. 64GB is for 4K video editing and other heavy creative work, not games. Here's why, and how to spend less while memory prices are this high.

What most gamers have

In Valve's September 2026 Steam Hardware Survey, 32GB passed 16GB as the most common amount of memory: 42.2% of Steam PCs had 32GB, 37.8% had 16GB, 6.5% had 8GB and 3.7% had 64GB, as PC Guide reported on October 5, 2026. That happened even though memory costs several times what it did a year ago.

Your graphics card changes the answer

When a graphics card runs out of its own video memory (VRAM), games spill the extra into system RAM. TechSpot tested this in its 2026 RAM test: with an 8GB card, 16GB of system RAM caused bad stutter, and 32GB raised that card's 1% lows by more than 60%. With a card that has enough VRAM, most games ran fine on 16GB. So if you're buying an 8GB card, budget for 32GB of RAM.

Which speed to buy

• AMD AM5 (Ryzen 7000 and 9000): DDR5-6000 with the lowest latency you can find, usually CL30. The FPS Review found DDR5-6000 as fast as or faster than DDR5-8000 in most games on Ryzen 9000 (Aug 6, 2026).
• Faster kits aren't worth it for gaming. TechSpot measured DDR5-6000 CL30 only a few percent ahead of DDR5-5600, so a cheaper 5600 kit is fine when it saves real money.
• Turn on EXPO or XMP in the BIOS after you build. Without it, DDR5 runs at its slow default of 4800.
• Buy a two-stick kit (2x16GB for 32GB) so the memory runs in dual channel.

Saving money while prices are high

AI data centers are buying most of the world's memory (our RAM prices guide has the full story). In Tom's Hardware's RAM price index on October 26, 2026, the cheapest 16GB DDR5-6000 kit was $249, 32GB was $447 (its all-time low was $72) and 64GB was $989. 32GB of DDR4-3200 was $209.

• Already have a kit? Pick Reuse my RAM in the PC Wizard's Extras step. Your kit stays in the build at $0, and the Wizard picks a motherboard that takes it (DDR4 or DDR5).
• Have DDR4 to carry over? Tom's Hardware says a DDR4 build is worth considering in 2026, though it's a dead-end platform.
• Used RAM rarely fails. Our used-parts guide covers how to test it.

Build a PC and the PC Wizard check that your memory type matches the motherboard, so you can't pick a kit that won't fit.
