CUSU Desktop RAM — DDR4 & DDR5 High-Speed Memory Modules

Upgrade your desktop PC's performance with CUSU DDR4 and DDR5 UDIMM memory modules. Available in DDR4 (3200MHz / 3600MHz) and DDR5 (5600MHz / 6400MHz) configurations, these 288-pin DIMMs are engineered for both Intel and AMD platforms. Whether you're building a powerful workstation or leveling up your gaming rig, CUSU RAM delivers stable, high-speed performance backed by rigorous compatibility testing.

Key Features

• Dual Standard Support: Available in DDR4 (3200MHz, 3600MHz) and DDR5 (5600MHz, 6400MHz) — choose the right type for your motherboard.
• Aluminum Alloy Heatsink (Cooling Fin): Integrated heat spreader improves thermal dissipation during demanding workloads.
• XMP Support: DDR4 modules support XMP 2.0; DDR5 6400MHz modules support XMP 3.0 for easy one-click overclocking via BIOS.
• 288-Pin UDIMM Interface: Standard desktop form factor — compatible with Intel and AMD motherboards supporting DDR4 or DDR5.
• DDR5 PMIC & ECC: DDR5 modules feature a Power Management IC (PMIC) and Error Correcting Code (ECC) for enhanced stability and data integrity.
• Premium IC Selection: Each module uses originally produced ICs and passes rigorous tests for compatibility, reliability, and overall performance.
• Capacities: 8GB and 16GB single sticks available; 16GB×2 (32GB) dual-channel kits also available.
• Made in Mainland China

Technical Specifications

Important Compatibility Notes

• DDR4 and DDR5 are NOT interchangeable. DDR5 modules cannot be used in a DDR4 motherboard and vice versa. Please confirm your motherboard generation before ordering.
• Desktop Use Only: This UDIMM is designed for desktop motherboards and is NOT compatible with laptops.
• AMD Platform Recommendation: AMD's memory controller performs most reliably with DDR5 at 6000MHz or 6400MHz (Hynix A-die). Using other speeds on AMD AM5 platforms may require frequency reduction. If you are on AMD, selecting 6000MHz or 6400MHz is strongly recommended.
• Multi-Stick DDR5 Configurations: Using 4×DDR5 sticks may reduce the operating frequency. Intel CPUs default to 4000MHz (max 5600MHz) with 4 sticks; AMD CPUs default to 3600MHz (max 4800MHz) with 4 sticks. For best results, use 2 sticks in dual-channel configuration.
• XMP / EXPO Setup: DDR4 XMP 2.0 can be enabled in BIOS for automatic overclocking. If your motherboard does not support XMP, DDR4 1.35V modules will operate at 2666MHz or 2400MHz by default.
• Mixing RAM Kits: Mixing modules from different kits or brands without manufacturer-verified compatibility testing may cause instability or incompatibility. Purchasing a matched kit is always recommended.

Frequently Asked Questions

Q: What is the difference between DDR4 and DDR5 desktop RAM, and which should I choose?

A: DDR4 and DDR5 are different generations of memory technology and are physically and electrically incompatible — they use different slots and voltages. 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.

Q: Does the CUSU DDR4 3200MHz RAM work at full speed without enabling XMP in BIOS?

A: 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.

Q: Can I use 4 sticks of CUSU DDR5 RAM in my system?

A: 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.

Q: Is this RAM compatible with AMD Ryzen AM5 processors?

A: 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.

Q: Does CUSU RAM come with a heatsink?

A: Yes. CUSU DDR5 gaming memory modules feature an aluminum alloy heatsink (cooling fin) for improved heat dissipation during intensive tasks. The heatsink is already attached to the module — no additional installation is required.
