RAM tips
Populate all 8 available memory channels on your WRX90 motherboard to maximize memory bandwidth and unlock the full potential of the Threadripper PRO CPU.
Opt for ECC (Error-Correcting Code) Registered DDR5 RAM for enhanced data integrity and system stability, which is highly recommended for mission-critical professional workloads.
Monitor RAM utilization in your most demanding applications to determine if upgrading to a higher capacity (e.g., 128GB, 256GB, or more) would further improve performance and workflow fluidity.
Installation & XMP/EXPO
To achieve the recommended DDR5-6400 speed, it is critical to enable the AMD EXPO (Extended Profiles for Overclocking) profile in your motherboard's BIOS after installation.
Frequently asked questions
Should I enable XMP or EXPO for this RAM?
Yes, enabling the AMD EXPO profile in your motherboard's BIOS is crucial. This ensures your DDR5-6400 RAM operates at its advertised speed and optimal performance, rather than a slower default JEDEC speed.
What's the recommended RAM capacity for this CPU?
For the Threadripper PRO 9975WX, a minimum of 64GB is recommended for professional use. However, 128GB, 256GB, or even up to 2TB is ideal for heavy multitasking, large datasets, and advanced content creation workflows.
Can I use DDR4 RAM with the Threadripper PRO 9975WX?
No, the AMD Ryzen Threadripper PRO 9000 series CPUs, including the 9975WX, exclusively support DDR5 RDIMM memory. DDR4 modules are physically and electrically incompatible with the sTR5 socket and WRX90 chipset.
