RAM tips
Always install RAM in the recommended dual-channel slots (check your motherboard manual).
Enable XMP or EXPO profiles in BIOS for rated performance.
For gaming on Ryzen 7000/9000 (AM5), DDR5-6000 hits the memory controller sweet spot.
Installation & XMP/EXPO
After installing your RAM, enable the XMP (Intel) or EXPO (AMD) profile in BIOS to reach advertised speeds.
Frequently asked questions
Does RAM speed matter for gaming?
Yes — especially on AMD Ryzen platforms. DDR5-6000 is the sweet spot for AM5; going higher brings diminishing returns. Intel platforms are less sensitive but still benefit from DDR5-5600+.
How much RAM do I need?
32 GB (2×16 GB) covers gaming and most productivity tasks comfortably. Go 64 GB if you run VMs, large datasets, or heavy video editing.
What is XMP / EXPO?
XMP (Intel) and EXPO (AMD) are BIOS profiles that set your RAM to its rated speed automatically. Without enabling them, RAM typically runs at a slower base speed (e.g. 4800 MT/s instead of 6000 MT/s).
