RAM Buying Guide
Updated for 2026 — everything you need to pick the right DDR5 kit for your build: speed, capacity, and the overclocking profile that unlocks it.
DDR5 is the only memory standard worth buying for a new build in 2026 — but the market is confusing. Speeds range from 4800 to 8000+ MT/s, latencies vary widely, and prices remain higher than DDR4 was at the same point in its lifecycle. The good news: the right choice is simpler than the spec sheets make it look.
Three things decide a RAM purchase — speed, capacity, and the overclocking profile that unlocks the rated speed. Get those right and you're done; chasing anything beyond that mostly wastes money.

Best RAM for...
#1 BEST FOR AMD RYZEN
DDR5-6000 CL30 (2x16GB) ~$110
32GB | DDR5-6000 | CL30 | EXPO
The universal recommendation for Ryzen 7000/9000 builds. AMD's Infinity Fabric runs 1:1 with memory at 6000 MT/s, so this is the exact point where speed and stability line up — going faster rarely helps and can even hurt.
#2 BEST FOR INTEL CORE ULTRA
DDR5-6400 CL32 (2x16GB) ~$120
32GB | DDR5-6400 | CL32 | XMP 3.0
Intel's newer memory controllers scale further than AMD's. DDR5-6400 is the sweet spot for Core Ultra 200/300 builds — extreme kits past 7200 MT/s exist but deliver diminishing returns outside of benchmarks.
#3 BEST FOR STREAMING / MULTITASKING
DDR5-6000 CL30 (2x24GB) ~$160
48GB | DDR5-6000 | CL30 | EXPO
For gaming plus OBS, heavy Discord use, or a browser with dozens of tabs open, 48GB gives real headroom over the 32GB baseline without paying content-creator prices for 64GB+.
Speed & Latency: What Actually Matters
Speed is measured in MT/s (megatransfers per second), and latency in CAS Latency (CL) — the delay before memory responds to a request. The two work together: DDR5-6000 CL30 has lower latency than DDR5-6000 CL36, but the real-world gaming difference between CL30 and CL36 is typically just 1–3 FPS in CPU-bound titles, and close to nothing when the GPU is the bottleneck.Past the platform sweet spot, faster kits mostly show up in synthetic benchmarks, not actual gameplay — and can be harder to stabilize without manual tuning.
How Much Capacity Do You Need?
• 16GB — workable for pure gaming with nothing else running, but tight. Titles like Cyberpunk 2077 with path tracing or Black Myth: Wukong at Ultra can push 14–15GB on their own, leaving no room for Discord or a browser.
• 32GB — the standard 2026 gaming configuration. Handles every current title with comfortable headroom for background apps, and is the capacity we recommend for nearly every build on this site
.• 48–64GB — only worth the premium if you stream, edit video, run virtual machines, or keep large local AI models loaded alongside gaming.
Platform Speed Reference
Platform | Sweet Spot | Capacity | Profile |
AMD Ryzen 7000/9000 | DDR5-6000 CL30 | 32GB (2x16GB) | EXPO |
Intel Core Ultra 200/300 | DDR5-6400 CL32 | 32GB (2x16GB) | XMP 3.0 |
Legacy AM4 (Ryzen 5000) | DDR4-3600 CL16 | 32GB (2x16GB) | EXPO |
Legacy LGA1700 (12th–14th Gen) | DDR4 or DDR5-6000 | 32GB (2x16GB) | XMP |
Buying Checklist
• Buy a matched 2-stick kit, not a single module or four sticks — two sticks gives you dual-channel bandwidth with the most stable timings.
• Confirm EXPO (AMD) or XMP 3.0 (Intel) support — most quality kits support both, but check before buying if you're unsure which platform you're on.
• Always enable the profile in BIOS after installing — RAM defaults to slow JEDEC speeds out of the box, and forgetting this step is the single most common reason a new build feels slower than expected.
• Skip RGB premiums if $/GB is your priority — lighting doesn't improve performance, and non-RGB kits are often meaningfully cheaper for identical specs.
