As Martin Broosk says run memtest. You can run the user space memtester on circa 90% of the RAM. Ever better download https://www.stresslinux.org/sl/ Format a USB stick and boot from it. Then run the memtester utility there.
On a server I would advise to use the iDrac or BMC and get a list of the hardware events also.
