Configure at 307Amp, set PL1 to 125W, PL2 to 253W, and apply a 50µV undervoltage.
Baseline Profiles seem accurate. I expect updated BIOS releases late in May that match Intel's official defaults rather than manufacturer-specific changes. If you encounter problems, consider submitting a support case to Intel. I'm currently working on troubleshooting a thermal throttling issue with my 14900K, which handles TJMax100c well without performance drops.
Tried another 14900K configuration, adjusted all previous limits like AC Loadline, CEP, etc., but it still crashes. Believed maybe RAM was too much, so removed two sticks and used 98GB, but issue persisted. Considered GPU problem, swapped the 3090 for a 4060ti I owned, but crashes continued. Planning to add a 13900k once I can afford it and check the results.
It's mostly the mobile part. Over the past two years, Asus motherboards have seen a drop in quality since the H55 line. They often fail quickly. My nearby shop has had more than 200 Asus Z790 €800+ boards returned via RMA in just one month. They won't be supported starting June due to contract expiration. Clearly, this is the least reliable brand you can purchase right now—every other option performs better.
This is apparent an issue with wattage draw and is an ASUS issue - I would manually set the voltages. Buildzoid has pointed out how this isn’t a wattage issue per se but is a voltage issue. I would find the stock voltage settings, manually fix them to that value and then slowly reduce the voltage until you get stability. edit; here re and he https://youtu.be/UBAxbPTCXg4?si=C1YPxk3gr8ZmQN6N
I sensed you were correct…but I didn’t want to accept it until I could explain why this board worked. I visited Best Buy and purchased another Z790 Maximus Hero to check its performance under different settings. I also brought along an MSI z690 pro-a DDR4 board for testing. After some trials, the crashes stopped completely. There was no undervolting involved—just a 253 watt pl1 and pl2 limit. I learned from online sources that crashes often happened when the CPU ran above 5GHz while core ratios stayed at default. I also noted that on Asus Z790s, the Intel diagnostic tool always passed until the prime number test failed, but it cleared completely on the MSI z690. So, I think it’s best to avoid these Asus Z790 models until we find a better solution.
