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!

7200 on a prime board with 4 slots is pure luck. In your case, you didn’t have any. I wouldn’t blame the cpu before you’ve tried it on a proper motherboard.
Or just run 6800 or something, the difference isn’t huge.
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
And which timings did you have on 13600 and now?
I had everything the same. 7200mhz 34-42-42-84. Only works on 13600kf
It depends motherboard, ram and memory controller in cpu. My friend has 13900k and ram runs on 8000 with all timings manually decreased, I have 13700k and the same ram works on 7200, but I have another motherboard
with my 14900 KF I can’t break 4,000mhz DDR4 gear 1 On my board. Turns out anything above the 1.35/1.3 95 volts to the VDDQ causes system crash so I keep it at about 1.35 with the SA at 1.35, looks like I’m going to have to tighten up my latencies instead
You need to find sweet spot voltage and RAM timing at 7200MHz.
SA Voltage / IMC Voltage / TX Voltage / VDD / VDDQ.
Also make sure the CPU pass stablity test first @ stock.Bad luck, this is why I don’t really like buying hardware for “OC potential” anymore. I’m generally not lucky when it comes to this stuff.
First I don’t think that mobo is capable of 8000mhz second try to re seat the cpu, this CPUs are very sensitive to having just the right pressure to run faster memory clocks
