Here are the beep codes for MSI motherboards.

What do the BIOS 'beeps' and codes mean? | MSI HQ User-to-User FAQ

Two beeps may indicate a bad RAM stick or improper configuration. Remove all but one stick of RAM and see if the system will boot. If it doesn't then try another stick. If you have changed BIOS settings to overclock RAM already try clearing the CMOS according to your motherboard manual's instructions.

The first place I go to check for compatible RAM is the QVL for the motherboard as these are the sticks that have been tested on the motherboard. The second place to go is to the RAM manufacturer's website, where you look up the model number of the motherboard.

If you choose to replace your RAM, G-Skill is widely recommended here.
