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

<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
