RAM catalog

RAM (Random Access Memory) is your PC's short-term working memory — the high-speed staging area where the CPU stores active program data, browser tabs, game assets, and operating system processes. Unlike storage, RAM is volatile: it is cleared every time you power off. But it is also dramatically faster than any SSD or hard drive, which is why the CPU reads from and writes to it constantly during operation. Installing too little RAM forces your system to swap data to the much-slower storage drive, causing stuttering, long load times, and overall sluggishness.

Key specs to understand: Capacity is measured in gigabytes (GB). 16 GB is the comfortable minimum for gaming and everyday use in 2024; 32 GB suits content creators, programmers, and heavy multitaskers; 64 GB+ targets professional workstations running virtual machines, large datasets, or complex rendering jobs. Generation (DDR4 vs DDR5) must match what your motherboard supports — they use different socket keying and are not interchangeable. DDR5 is faster and more power-efficient but costs more and requires a compatible platform (AM5, LGA 1851, or Intel 12th+ Gen with DDR5 support). Speed (MHz/MT/s) and latency (CAS) work together — a DDR5-6000 CL30 kit is generally better than DDR5-7200 CL40 because the lower latency offsets the higher frequency. For AMD Ryzen, hitting the CPU's Infinity Fabric sweet spot (DDR5-6000 for Zen 4) is more important than chasing the highest raw speed. Dual-channel configuration (two matched sticks) roughly doubles memory bandwidth versus a single stick, providing a meaningful performance uplift, especially for integrated graphics and some gaming scenarios.

Budget guide: Entry-level (under 800,000 ₫) — a 16 GB DDR4-3200 kit is sufficient for everyday computing, entry-level gaming, and student workloads. Paired with a budget CPU and GPU, it delivers a smooth Windows experience without breaking the budget. Mid-range (800,000–2,000,000 ₫) — 32 GB DDR5-6000 covers gaming at 1440p, streaming, and casual content creation without compromises. This range is ideal for most PC builders who want performance that remains relevant for several years. High-end (above 2,000,000 ₫) — 64 GB+ kits, high-speed DDR5-7200+ with custom ICs, and RGB enthusiast modules target workstation builds, competitive overclockers, and creators working with 4K+ video or very large datasets where memory capacity directly limits what jobs can be loaded into RAM at once.
