How much RAM do I need for gaming?

16 GB is the minimum, 32 GB is the recommendation for a new gaming PC. Take two sticks so the memory runs in dual channel.

Can I put DDR5 in a DDR4 motherboard?

No. DDR4 and DDR5 have a different notch and don't fit each other's slot. Your motherboard's specifications tell you which type it supports.

Two sticks are the best choice for most PCs: they reach their full speed more easily. Four sticks give more capacity, but DDR5 sometimes runs slower then.

Can I mix different sticks?

It can work, but the PC then uses the slowest speed and problems are more likely. A kit of identical sticks is the safest choice.

Memory (RAM) holds what your PC is using right now: your game, Discord, your browser. Too little RAM causes stutter, even with a fast processor. At COZO you'll find DDR5 and DDR4 for desktops and SO-DIMM sticks for laptops and mini PCs, as single sticks or kits of two. Filter on the left by memory type and stick height.

DDR4 or DDR5?

The type depends on your motherboard, not on preference. AMD AM5 and Intel LGA1851 work with DDR5 only. AM4 uses DDR4. Intel LGA1700 comes in both versions: the board decides. DDR4 and DDR5 physically don't fit each other's slot, so the wrong stick simply won't go in.

Laptops and many mini PCs need SO-DIMM, a shorter stick. It's in the product name.

How many GB is enough?

Prefer a kit of two identical sticks (2 x 16 GB rather than 1 x 32 GB). That way the memory runs in dual channel, which is noticeably faster. Playing Minecraft with lots of mods? Our lists what Mojang recommends.
