I run decode-dimms and it detect 3 DIMM modules in the 3 slots but another 3 DIMM decode-dimms can't detect. lm-sensors 3.3.3 decode-dimms in the i2c-tools 3.1.0-3 and even I tried rev.6068 kernel 2.6.32.20 and even I tried 3.4.2 motherboard - Supermicro X8DTG modprobe i2c-i801 modprobe i2c-dev modprobe i2c-core modprobe eeprom 'i2cdetect 3' give table something like this 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: 20 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- UU -- UU -- UU -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: 50 -- 52 -- 54 -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- ls /sys/bus/i2c/drivers/eeprom/ 3-0050 3-0052 3-0054 i2c-dev... i2c-dev... i2c-dev... decode-dimms give out something like this $ decode-dimms # decode-dimms version 6068 (2012-11-.. ) Memory Serial Presence Detect Decoder By Philip Edelbrock, Christian Zuckschwerdt, Burkart Lingner, Jean Delvare, Trent Piepho and others Decoding EEPROM: /sys/bus/i2c/drivers/eeprom/3-0050 Guessing DIMM is in bank 1 ---== SPD EEPROM Information ==--- EEPROM CRC of bytes 0-116 OK (0xF02A) # of bytes written to SDRAM EEPROM 176 Total number of bytes in EEPROM 256 Fundamental Memory type DDR3 SDRAM ...
