In BIOS maximum dram frequency option is 1600mhz

[lasha.gabashvili]

Hello, today I bought a brand new 2x4gb Ripjaws ddr3 1866mhz but here is the thing when I headed to BIOS the maximum dram frequency option I saw there was 1600 but my mobo says it supports even 2400mhz... here is the link - https://imgur.com/a/k90GR8d

my mobo is ZH77A-G43 and cpu is i7-3770

You're limited to 1600 due to the chipset and the processor:

See if you're able to perform a BIOS update(non Beta) and if you gain any frequency options past 1600MHz.

I did a bios update, I don't think it must be CPU because this mobo must let me have more frequencies

You can do that by overclocking.

Good Luck overclocking an Intel H77 motherboard.
