Agreed it's 4 beeps, SYSTEM_TIMER_FAILURE.
First thing to try is removing three RAM sticks and try it on just one stick. Try it again on each of the 4 sticks, one at a time. See whether you get the 4 beeps on each of the RAM sticks.
Late edit after a bit of research: Once you've tried it with all four RAM sticks in individually, try booting again four times and rotate the RAM sticks through the four slots so that each time you boot each RAM stick is in a different slot.
Edit: Also try the suggestion from @Nursemorph to remove and reseat the CMOS battery. TBH, and to be on the safe side, I'd replace the battery - they cost pennies.
