--- Comment #163 from Don Lewis <truck...@freebsd.org> --- (In reply to Mark Millard from comment #159) This is what dmidecode reports on my machine: Handle 0x0027, DMI type 16, 23 bytes Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: Multi-bit ECC Maximum Capacity: 64 GB Error Information Handle: 0x0026 Number Of Devices: 4 Handle 0x002E, DMI type 17, 40 bytes Memory Device Array Handle: 0x0027 Error Information Handle: 0x002D Total Width: 128 bits Data Width: 64 bits Size: 16384 MB Form Factor: DIMM Set: None Locator: DIMM 0 Bank Locator: CHANNEL A Type: DDR4 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 2400 MHz Manufacturer: Micron Technology Serial Number: 14C07593 Asset Tag: Not Specified Part Number: 18ASF2G72AZ-2G3B1 Rank: 2 Configured Clock Speed: 2400 MHz Minimum Voltage: 1.2 V Maximum Voltage: 1.2 V Configured Voltage: 1.2 V [snip] Note the "Error Correction Type: Multi-bit ECC". The individual DIMMs are a bit strange. On my other machines the ECC bits are included in "Total Width". I have visually verified the extra RAM chips for the ECC bits are present. This is what I see on my FX-8320E machine: Handle 0x002C, DMI type 16, 23 bytes Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: Multi-bit ECC Maximum Capacity: 32 GB Error Information Handle: Not Provided Number Of Devices: 4 Handle 0x002E, DMI type 17, 34 bytes Memory Device Array Handle: 0x002C Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: 8192 MB Form Factor: DIMM Set: None Locator: DIMM0 Bank Locator: BANK0 Type: DDR3 Type Detail: Synchronous Unbuffered (Unregistered) Speed: 1600 MT/s Manufacturer: Micron Serial Number: 0D43FEC Asset Tag: AssetTagNum0 Part Number: 18JSF1G72AZ-1G6E1 Rank: 2 Configured Clock Speed: 800 MT/s -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
