The fact boot codes displays are getting pushed to always more expensive motherboards - and there is no standard way to get them otherwise - drives me crazy.
The economic tradeoff would be interesting.
How many good boards get RMA'd because they provide no feedback that you're in the middle of memory training, versus the $1 BOM addition to put a seven-segment display-- or hell, one of those 1" OLED modules-- on boards other than the $300+ "Autonomous Collective of Joystick Monkeys" X870E Torpedo Grenade ExplodyThingy Max?
> DDR5 memory training.
That makes sense. I also have a newer host that uses DDR5 RAM. The first time I powered it up, I thought it was not working. While I was sitting there trying to figure out what to try nest, It finally came up. It gets better with time (or BIOS updates.)
This is actually a huge problem with DDR5 memory training. Since memory training must happen before the GPU is brought up, the screen stays blank for that duration (which can take several minutes). The only indication that it's happening is in debug LEDs if your motherboard has them.
