Yes am5 has long boot times as in every boot the ram goes through memory training. It has been a thing for long before ddr5. Ram training will cycle as many as 5 times to test settings. Reply reply More replies More replies More replies So my gues RAM OC dont work because rubbish bugged BIOS. I’ve now removed one of the two sticks on hopes it would train faster while i’m writing this. Memory training does not affect timings or speed of RAM unless failure to default occurs. Some boards have a BIOS setting to keep memory training stored after initial boot and memory training. So it trains the Timings everytime and thats takes so long. Después de salir eso por dos segundos, desaparece y solo se queda en "Memory PMU Training" Estuve investigando y leí en algun lado que eso puede hacer que mi sistema tenga fallos en el rendimiento. Boot times between 4-5 minutes (which just seems to be failed EXPO-training as the memory is set to JEDEC-settings when it actually boots). They've not reported any issues and this was handed to them months ago. After 3-4 minutes you can assume it failed. Best practice is to let a new system (or if you replaced the ram) to run through some memory training cycles. It cant be because IMC in CPU because its stable with 6400mhz with 1:1 Ratio and it cant be because Memory(Hynix A-die and they runs super great in 6400/6200mhz) BIOS 1222 (AGESA 1. E5 but ComboPi 1. 5 Patch C) is by all accounts an utter shitshow on the B650E-F and similar AM5 boards. ~= 14gb of GPU VRAM. Do not use this BIOS or be extremely cautious.
