MSI X99S SLI Plus 3 beeps on startup

[Horrgakx]

Hi all - my MSI X99S SLI Plus beeps 3 times when I switch the computer on, no other messages are displayed and there are no clues either in the BIOS screen or Win10 (which boots normally).

I have tried running Memtest (from memtest.org) which is a bootable CD, the full memory scan ran for more than 24 hours and it successfully completed 6 consecutive scans.

I've tried searching for this error and there's loads of posts but nothing seems to be right for this problem.

Can anyone help please?

Bump.

It's also worth me mentioning that the most up to date bios version is installed (1.90).

Can anyone help please?
