![]() Your variable results mostly belong to bad memory training and maybe PSU idle instability - but AMD CBS has an option for that one too ![]() Go back to 1003ABBA if you want, or 1004B IF AMD Overclocking menu exists there I have something similar on a X399 Bios, where the boot-order menu is fully broken and freezesīut no, PSP Firmware update is not a bad thing ~ except preventing us to use PCIe 4.0 and having to buy overpriced B550 Boards :ninja: It crashed soo much, that the cpu mentioned PSP FW Reset enforced, please remove the cpu and put it back in to reset PSP Firmware Memory timings where soo broken, that the main core-bootloader (before the bios) froze Some bioses indeed push >1.3vSOC or 1.2+ cLDO_VDDG early on by defaultĬlick to expand.I suspect, AMD did low level changes (PSP Firmware) as a result to have now consistent behavior on lower versionsĪbout the Chinese Bios bug, i had that once on the B350 Toma Usually 1003ABB is the place where you got a Pcie 4.0 lockdown and a big PSP Firmware update was madeīut 1003ABBA should be fine enough als middle step, before you continue beyond 1004 Soo if you decide to do it, downgrade strongly to 1003A, then upgrade normally to 1003ABBA and only afterwards decide if you want 1004B or 1006/1002v2 I am not sure if the units would like 900mV VDDG and 1v VSOC onlyĪlthough, remain with identical voltage jumps across them - if you decide to use higher "stepping/voltage jumps" This would require double 75mV stepping everywhere It can be, that the recommended values are now far lower PSP Firmware on the Units updates between AGESAs, and as 1.0.0.5/1.0.0.6 changed quite a few things and lowered voltages Well if it pushes 1.25v VDDG it might exceed 1.3vSOC It's far to high, and vSOC can not be less than 1.25v if VDDG is that highīut the CPU shouldn't degrade by 1.2vSOC, only 1.3+ Click to expand.Some bioses indeed push >1.3vSOC or 1.2+ cLDO_VDDG early on by default
