Question XMP setting dont save

[hermis]

Hi,

ASUS H81M-E/M51AD/DP_MB

i5-4460S

Both should is able to run ram with 1600mhz.

bought new sticks corsair 2x4gb 1600mhz 9cl and installed everything works but they run 1333mhz.

In bios i have an XMP option but it wont save and on reboot its ”disabled” again.

I got No other AI tweak option in BIOS.
