[SOLVED] M.2 running slow after CPU update

[epipen12]

Hi there,

I have the Gigabyte Aorus Pro AX Z490 with the Intel i9 11900K processor that has just been upgraded from the i9 10900F. Since then, my SSD's have gone from 3000mpbs to about 890mbps.

I have done the following;

• Re-installed windows
• Install correct drivers
• Boot is UEFI and partitions are GPT
• Latest bios (F20d) has been installed
• Firmware on SSD's are up to date.
• SSD's are showing as m.2 in my bios (as expected)

My SSD's are;
Western Digital Black SN850
Sabrent Rocket 4 Plus

Any advice?

Cheers

This has been solved over at Reddit;

"are you using the top m.2 reserved to 11th series CPUs?
move the most important SSD to the top m.2 (M2B_CPU) and leave the other in M2A_SB"

so you didn't read the manual.
