Need Q-code code definition

Dec 19, 2014

I have a ROG Crosshair VIII Hero Ryzen 3900x G.Skill 3600 and Sabrent PCIE4 M.2, with the latest BIOS and latest chipset drivers, and occasionally I get the following Q-Code -
F8 (Recovery PPI is not available)
In normal terms can anyone define or explain the meaning. I can't even figure out what PPI means - too many PPI acronyms.
I almost know when I'm going to get this error, as my fans start to spin up and down slightly (IOW I can hear it subtly).

Quick google search brought THIS and THIS I just googled ROG Crosshair VIII Hero Q-Code - F8 first couple were from ASUS ROG forums....
Looks like a BIOS is necessary so you get in and tweak memory settings. Sorry for lack of detail, just went with a fast down and dirty search.

I searched extensively for an explanation and came up blank. I don't know why so many of the Q-codes (on all boards) are so cryptic and lacking in descriptiveness. In most cases you get that one line in the manual and that's it. Frankly it's always been that way.
Perhaps it suits the Asians who make the boards in the sense that if you are (cryptic) you don't really have to speak English or Western languages. I mean somebody has to know the practical meaning so maybe they do.

Now I do notice that the minute I start Ryzen Master I get this error, which coincides with some complaints in various forums.

Just by chance, have you tried without the pcie4 drive? Only difference between our setups before the gpu, and I have yet to run into this. Using the MP510 drive on mine
