Question Getting IRQL_NOT_LESS_OR_EQUAL after PC overhaul

[jurgo4509]

Hello!
I have recently overhauled my PC with a new mobo, memory and cpu.
My specs are:
ASRock Z370 Killer SLI (BIOS ver. 4.30. - newest)
Intel Core i3-9100f
MSI GTX 970 Gaming 4X
Crucial Ballistix Sport LT Gray, 2x8GB DDR4 @2666MHz, CL16
FSP 460W OEM PSU
Cooler Master Hyper 212 RGB Black cooler
Patriot Burst 120GB SSD
Toshiba P300 1TB HDD
I am running a fresh install of Windows 10 and have already reinstalled multiple times. I let memtest86 run 10 passes overnight and got 0 errors.
The BSOD's happen seemingly randomly but seem to increase in intensity until I run memtest which i find very weird. Clearing the CMOS helps for a while but then the BSOD's start happening again like described above.
Any help would be apreciated. Thanks.

i3 does not use 2666MHz memory. It may not run well if your forcing that speed.

I've been running it underclocked to 2400MHz for a while now. Could it be that before I underclocked the speed, it had done damage to the system in some way?
