Dear Daniel,

I think most of the time is spent in RAM initialization.
- Do board owners with similar amount of memory (independent of the board) have similar numbers?
- What are the ways to improve that? Is it possible? For example, can the modules be probed in parallel (if that isn?t done already)?
Regarding 1: I am running 128GB in 8GB modules (LRDIMMs) and experiencing a similar issue. With just two UDIMMs, the boot times are *much* faster.
That’s good to hear. Do you have concrete numbers?
Also, the vendor BIOS is faster from the time you press the poweron button to the time the monitor gets a signal.
I believe that’s a design decision in coreboot, that the display can only be initialized after RAM has been initialized. The vendor firmware seems to be able to do it beforehand. (If I am wrong, the vendor firmware is really fast in configuring the memory.)
Thanks,
Paul
