Snmp oid index for physical RAM and cpu got changed in windows servers(2003,2008)

what circumstances under snmp oid index of physical ram can change?

i know physical ram , cpu oid change after  ram/cpu upgrade done

my question is:

can physical ram/cpu  oid change if windows server  restarted simply?

can physical ram/cpu  oid change if windows server  restarted after windows patch applied?
