I recently upgraded an old notebook. It had 2GB of RAM, and dmidecode assured me it would support 4GB. Although dmidecode said that both slots would support 2GB, it turned out only one of them does.
I searched around a bit more and I now suspect the 2GB slot might actually support 4GB, but I don't want to spend money on this bet (it's an old machine with a Core 2 Duo processor).
So now I'm left wondering how dmidecode can be so wrong.
- dooglius 6y agoAre you sure it's dmidecode that's wrong, and not the DMI itself? dmidecode just parses what's given to it by the BIOS.
- forinti 6y agoYes, I agree. Still, you can't trust the result.
- kylec 6y agoSome versions of the Core 2 Duo can only support up to 3GB of memory. It’s possible that your CPU is the limiting factor, not your memory slots.
- kosma 6y agoDMI information is supplied by BIOS - and those can be very, very wrong. More often than not the only DMI/ACPI information correctness the manufacturer cares about is "Windows doesn't complain".
