Loud beeps when the system is running is NOT RAM.
It's either fan/temperature alarm or a power line out of specification alarm.
Most likely at this time of year is temperature. You can often check the temperatures and fan speeds by looking in the BIOS. If not the free Everest program will do it. click here
If the power is out of kilter, then again this may show in the BIOS or via Everest.
Fixing it just depends on finding which it is.
