DDR5 is the current memory standard for AMD AM5 and Intel 12th-gen and newer platforms. It brings higher bandwidth and better power efficiency compared to DDR4. For gaming, the sweet spot is well-established — and spending more on faster RAM gives diminishing returns fast.
6000 MT/s CL30: The current sweet spot for AMD Ryzen 7000/9000. Runs 1:1 with the memory controller for best latency. Almost every AM5 CPU can handle this.
6000 MT/s CL36-40: Slightly looser timings, often cheaper. 1-3% slower in games — barely noticeable.
6400+ MT/s: May require manual tuning or not work 1:1 on AM5. Gains are single-digit percentages. Not worth the premium for gaming.
16GB (2×8GB): Bare minimum. Workable but closing background apps is a habit. Not recommended for new builds.
32GB (2×16GB): The standard for gaming builds. Headroom for multitasking, streaming, and future games. This is what you should buy.
64GB (2×32GB): Content creation, VMs, heavy productivity. Overkill for pure gaming.
Always prefer 2 sticks over 4 on DDR5. Four sticks stress the memory controller and often can't reach rated speeds — you'll be stuck at 4800-5200 MT/s instead of 6000. If you need 64GB, buy a 2×32GB kit, not 4×16GB.
RGB adds $10-20 for the same performance. Heat spreaders are mostly cosmetic on DDR5 — the modules run cool. Low-profile sticks (no tall heat spreaders) are better if you're running a large air cooler that overhangs the RAM slots.
All the same silicon: G.Skill, Corsair, Kingston, TeamGroup, and Crucial all use chips from the same three manufacturers (Samsung, SK Hynix, Micron). Brand differences are in the heat spreader design, RGB software, and binning quality. Buy based on speed/timings and price, not brand loyalty.
Single-channel (1 stick) — cuts bandwidth in half, costs significant FPS. DDR5 below 5600 MT/s — might as well have gone DDR4. Four-stick configurations on AM5. Paying extra for speeds above 6400 MT/s for gaming.
