My old SGI 440 does this - if I run a program called /etc/ecc, I get a list of momory corrections:
%/etc/ecc ECC errors logged: Legend: DBxx - single data bit corrected CBx - single check bit corrected 2bit - double bit uncorrected unc - multi-bit uncorrected SIM locations assuming only 1Mbit SIM boards <phys address 272-274Mb a3 = 1, syndrome = DB03> SIM:address OOR for configuration
SIM locations assuming 1Mbit SIM & 4Mbit SIM boards <phys address 272-274Mb a3 = 1, syndrome = DB03> SIM:2nd memory board:M4K0
SIM locations assuming only 4Mbit SIM boards <phys address 272-274Mb a3 = 1, syndrome = DB03> SIM:2nd memory board:M4O8
