Hi,
I'm having a problem with my RAM.
Memtest fails.
thats why I wanted to read the SPD but this failed.
Fails with different Brand RAM modules.
So it appears to be related to the board.
Passmark Memtest86 7.5 cannot read the SPD either.
not sure if windows programs work. will test.
any idea what's wrong?
thanks

I did a modprobe for i2c-i801 and eeprom, then
$ sudo i2cdetect -l
