Recently got the 14900K from Amazon, and I’m facing some issues with RAM overclocking on my ASUS Prime Z790-P. Before upgrading from my i5-13600KF, I had my RAM running smoothly at 7200MHz with just 1.38V and 1.38VDDQ. However, my new 14900K struggles to handle 7200MHz, even at 1.45V and 1.45VDDQ. After running OCCT stress tests for about 1-2 minutes, my PC freezes, and I get a (41) kernel error. Is this normal, or should my 14900K be capable of running 8000MHz RAM without issues? Looking for advice and insights here!

If your ram was running fine at 7200 on the same motherboard then obviously the problem isn’t the motherboard as some people are commenting. Try to play around with SA and VDDQ voltages, sometimes lowering them does the trick. 1.45v is excessive for those speeds, I need 1.30 for 8000 mhz so…
1.45 is not excessive for 7200 MT/s with tight subtimings. Most of the Hynix A-die chips with default XMP at 7200 are running at 1.45V
