Discussing 3700x core and fclk frequencies
Configuration details: 3700x, MSI B450 mortar max, 16Gx2, 280mm AIO, PBO active. Adjusting dram:fclk to 3733:1866 allows smooth Aida64 FPU stress testing at 4000-4100MHz core frequency. At 3800:1900 it limits testing to a steady 3900MHz with a cooler 10°C. Raising the frequency beyond these points causes immediate reboot after about a minute. The drop in core frequency appears linked to the higher fclk setting. Possible solutions include optimizing BIOS parameters or adjusting clock speeds within safe limits.
The core voltage during the stress test is measured at a specific height, typically referring to the peak value observed at that level.
Around 1.38V operates at 3900mhz core&ddr4 3800, dropping to about 1.3V, but it will restart if you force it to run at a higher frequency manually.
then you're limited by FCLK or maybe UCLK indeed. SOC voltage 1.1V? If this doesnt help then you're back to 3733/1866 setup. It just cant handle the extra work when frequency increases. also 1.38V all core is higher than what I would use in all core stress situations, I'd keep it to 1.35v since it's a smaller node than before and there's not a lot of data on what happens if you push 1.4V for a long time into the CPU.
