Installed memory to allocated memory mismatch in dashboard

[fishface]

V6.0.1

 

I have 2 x 2GB sticks installed, in the dashboard it states the following.

 

Memory size 3704

installed 8192 MB (max. 16 GB)

 

So why does it think I have 8192 installed?  What am I missing here?  Surely I have 4096 installed?  Or is it including disk swap?

In 6.1.8 I am having the exact same issue.  I have a single 16GB chip installed and the dashboard is reporting 16GB allocated and 32GB installed.  I tried a different RAM chip and it did the same thing (reported double installed).

 

If it matters this is on an ASRock E3C236D2I motherboard.

Can you post the output of the command:

 

dmidecode -t 17

Here is the output from dmidecode.

dmidecode is reporting the same module twice, either a bug in dmidecode or your SMBIOS.  It would be interesting to see if there's a newer version of dmidecode, and whether it would do better.

[bonienl]

unRAID v6.1.8 has the latest available version of dmidecode, which is v3.0, previously version 2.2 was used.

 

Did the size mismatch appear in unRAID 6.1.8 or also in earlier versions of unRAID?

 

Perhaps another solution can be a newer BIOS version of your motherboard (if available).

I don't know if it happened in previous versions as I just built this as a brand new server last week so it has only ever run 6.1.8.

 

As for BIOS, my board (ASRock E3C236D2I) is also brand new with no BIOS updates yet, I got one the the first boards to ship.

 

Is there another way to check with an older version of dmidecode?

You can download version 2 from the slackware repository

 

You need to install manually using upgradepkg

Downgrading to dmidecode v2 seems to fix the issue.  The output now only shows the dimm once and Unraid Dashboard correctly shows 16GB installed.

 

I did notice on the dmidecode v3 output it had two sections "SMBIOS 3.0" and "SMBIOS 3.0.0", both of which seem to contain the same, duplicate, information. It seems there is a bug in dmidecode v3.
