Can you mix memory speeds

[NeilCad]

Hi all,

i bought some ram to upgrade from 16g to 32g, i didnt check too much first but im having crashes and problems booting since, first i had Corsair LPX 3200 (2x8) 16-18-18-36 1.35v and recently bought Corsair LPX 3600 (2x8) 20-23-23-43 1.35v

should i be able to run these together if so do i need to tinker in the bios to get it working?

Mobo is Asus Z390 A
CPU is 9700k

Any ideas greatly appreciated

Should work ok but will run at slowest speed of the combined sticks.
