DDR5 offers higher speeds (5600MHz–6400MHz) and better efficiency, but requires a DDR5-compatible motherboard (e.g., Intel 12th\/13th\/14th Gen LGA 1700 with DDR5 support, or AMD AM5). DDR4 (3200MHz–3600MHz) is ideal for older platforms. Always check your motherboard's specs before ordering.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the CUSU DDR4 3200MHz RAM work at full speed without enabling XMP in BIOS?\u003c\/h4\u003e\n\u003cp\u003eA: By default, most systems will run DDR4 at JEDEC standard speeds (e.g., 2666MHz) unless XMP is manually enabled in BIOS. The CUSU DDR4 1.2V modules run at 3200MHz under JEDEC spec. The 1.35V XMP 2.0 variant requires XMP to be enabled in BIOS to reach its rated 3200MHz or 3600MHz speed. If your motherboard\/CPU does not support XMP, it will default to 2666MHz or 2400MHz.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use 4 sticks of CUSU DDR5 RAM in my system?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, but with limitations. Using 4 DDR5 sticks reduces the maximum stable frequency. On Intel platforms, the system defaults to 4000MHz (maximum achievable: 5600MHz). On AMD AM5 platforms, the system defaults to 3600MHz (maximum achievable: 4800MHz). For maximum performance, CUSU recommends using 2 sticks in a dual-channel configuration.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this RAM compatible with AMD Ryzen AM5 processors?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, but AMD AM5 compatibility is best ensured by selecting DDR5 6000MHz or 6400MHz (Hynix A-die) variants. AMD's memory controller can be more sensitive to high-frequency operation, so choosing the recommended speed options helps avoid EXPO configuration issues and ensures stable performance out of the box.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does CUSU RAM come with a heatsink?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. CUSU DDR5 gaming memory modules feature an aluminum alloy heatsink (cooling fin) for improved heat dissipation during intensive tasks.
