Support to turn off and turn back on DIMM modules quickly for either high-speed memory or large storage when required.
AMD RAM performance varies based on the number of DIMMs installed. Some configurations offer slower speeds with four DIMMs and quicker speeds with just two. It might be feasible to adjust dynamically which DIMMs are active depending on RAM demand, allowing you to balance between high-speed access and ample memory availability. This approach could help utilize more RAM or faster clock speeds without manually swapping modules each time.
No, the RAM is physically connected to the CPU. This setup is likely due to the requirement for 128GB, which can be achieved by using two 64GB modules.
Adjusting RAM quantity and clock speed demands a memory reset (unless you're handling BCLK carefully, which can cause issues). This isn't feasible. The nearest option is some boards allow enabling/disabling DIMMs via BIOS, which you might switch on during a restart. The challenge is limited AM5 models—only a few have this feature, mostly on Intel chips from the past decade. Simply swap in two 48GB modules and you should see DDR5 6000 CL30 work with Hynix DIMMs (6400 CL32 rated). Most systems won't need more than 96GB on AM5.
