Cpu overclock versus ram rated speed, along with XMP settings.
Cpu overclock versus ram rated speed, along with XMP settings.
Can I boost my CPU to its highest possible speed while still getting my RAM to perform at its rated capacity? Or do I have to pick between the two? For instance, if my CPU has a maximum stable frequency of 4GHz and my RAM is rated for 3200MHz, will I need to accept a lower frequency of 3.8GHz to match the RAM speed? I’m really confused but I’d rather not experiment until I understand it better. Thanks!
I noticed on Intel Skylake/Haswell that setting RAM to maximum XMP speed seemed to lower my stable OC multiplier by one. Probably some expert could do better, but I didn’t feel the need to explore it further.
My idea is that higher voltage required for the RAM controller to reach XMP settings might reduce the power available to the CPU core.
Generally, faster RAM doesn’t significantly boost performance on Intel processors.
I’m not sure how this affects Ryzen, where I believe RAM and CPU are more closely linked.

Hi Drakonath
The AM4 platform is still in the process of Bios micro-coding, with new Bios versions being released to support DDR4 RAM. It's recommended to select RAM kits that have been tested and listed on the MB QVL. You should also update to the latest Bios revision for better compliance, avoiding the need to adjust timings and voltages. The specific OC achievable depends on the CPU, with Ryzen "X" versions offering better results.
