I've found a tool dmidecode and linked the MCA: Addresses with properly address range on memory.
Is it correct?

The same memory bank as above?

There an utility to decode those messages: sysutils/mcelog

mcelog --ascii [ paste your log to STDIN ]

and got:
Code: 
CPU 30 BANK 13
MISC 918c2000200228c ADDR 35c9cbf780
MCG status:
MemCtrl: Corrected patrol scrub error
STATUS 8c000051000800c0 MCGSTATUS 0
MCGCAP 7000c16 APICID 30 SOCKETID 0
CPUID Vendor Intel Family 6 Model 63
Hardware event. This is not a software error.
CPU 30 BANK 8
MISC 152606086 ADDR 35c9cbf740
MCG status:
STATUS 8c00004000010090 MCGSTATUS 0
MCGCAP 7000c16 APICID 30 SOCKETID 0
CPUID Vendor Intel Family 6 Model 63

--> MemCtrl: Corrected patrol scrub error

As I understand some memory error was detected and corrected.

mcelog should also provide the location of the ram bank, but obviously that can't be run from my machine. (see option --dmi).

Yep. Those are memory errors. They've been corrected due to ECC so there's not a direct problem but the module does need to be replaced. And it looks like you have found the correct modules.
