Question HyperX Impact downclocks to 2133 MHz? Asus A442u

[Onlyauser]

Hello Members,


I have an Asus Vivobook A442U. It has an intel core i5-8250U processor (8th gen, memory support DDR4 2400 MHz max. speed) with 4GB onboard memory (DDR4 2400 MHz). Since the onboard memory is only 4 GB I decided to max out the RAM by adding an 8GB Kingston HyperX Impact stick to it. The memory is now 12 GB but somehow the speed downclocks to 2133 MHz. I am not sure if this laptop supports XMP because last time I checked in BIOS I can't seem to find the XMP setting. Does anyone have any idea how to return the speed to 2400 MHz while having the HyperX Impact stick installed? Thank you

Is the new stick 2400 MHz?

I just checked with CPU-z and under the SPD tab it says :

max bandwidth: DDR4 - 2401 (1200MHz)
Module manuf.: Kingston

and in the timings table:

JEDEC #5: 1200 MHz
JEDEC #6: 1200 MHz
JEDEC #7: 1200 MHz
XMP-2400: 1200 MHz

but under memory tab:
DRAM frequency is sometimes 664.9 Mhz, sometimes 1064.1 MHz. Going back and forth

In task manager it says my memory is 2133 MHz. I'm really confused
