No, running overclocked RAM does not affect the CPU's IMC.
Using overclocked RAM at 3200MHz will affect the CPU's performance and power usage. With an Intel 11th gen or newer processor, it should handle DDR4 3200MHz without issues, especially when using XMP or OC settings. If you use a RAM rated for 3200MHz at 1.35V, the CPU may run at its default power and voltage, but with overclocked memory, timing might be impacted. Running at 2666MHz with lower timings and 1.35V could work if the CPU is set to stock power, though stability might vary. Always check your specific model's guidelines for compatibility.
When rams spin at 4200 RPM, the IMC drops to 2100 assuming gear 1; at 3200 it falls to 1600. A low 2666 might keep voltage around 1333, staying near defaults. The safe operating range for DRAM depends on the IC—some chips like Samsung C Die cap above 1.35V, while others such as Micron Rev E, Hyundai DJR, or Samsung BDie hold up past 2V (though DJR usually stops scaling below 1.9V). There’s a section of the IMC affected by DRAM voltage, but a safety limit of 1.7V is set to protect against issues. Some builders follow the Buildzoid approach and externally power the rams, allowing the IMC voltage to be adjusted up to 1.5V or even 2V. Since you’re running at normal speed, any performance changes are minor and not a major concern.
