RAM info with dmidecode --type 17
The ASUS V-PRO Z77 motherboard has 2x2 (Kingston and Corsair) slats of RAM. All four bars of RAM do not cause any complaints in the work. They work properly. But, below is the output of the result of running the Dmidecode program and in the output I am interested in the following lines:
Error Information Handle: 0x0060
Error Information Handle: 0x0063
What does this mean and what does this information relate to?
$ sudo dmidecode --type 17
# dmidecode 2.12
# SMBIOS entry point at 0x000f04c0
SMBIOS 2.7 present.

This means that the error information is located in other records with the numbers 0x0060 and 0x0063, respectively.
In order to find out what is hidden behind them, dmidecode should be run without parameters and view the output. The handel numbers are specified in the headers in the output as follows:
Handle 0x005B, DMI type 17, 34 bytes

Probably their type will be 18 (32-bit Memory Error Information) or 33 (64-bit Memory Error Information).
Apparently, the very presence of a value in the Error Information Handle field is as long as the value Type: OK is in the structure to which it refers. How exactly the data is presented is determined by the implementation.
