RAM Usage showing error

Hi,
For 1 week, my one server is showing RAM usage on WHM is a little confusing. Look at these screenshots.

Look at both screenshots.
The terminal is showing correctly.

But the WHM Status page is showing it with cache also.

Is there any idea how can we fix that thing as normal?

The reason why you see different data set from WHM and free -m is because the WHM status reports pages doesn't rely (as you likely have guessed) on the free -m but on a historical RAM usage utility.

free -m does give you the current snapshot and it is a rather trustworthy output.

WHM status relies on the command:

sar -r

which would give a higher %memused than free -m.

Please note that you it is likely that you have some unclaimed cached memory which would increase the theoretical usage but not the actual one.

A good way to see whether you need more RAM is that if you see performances degradation and a high swap usage + RAM full on free -m

Replace the RAM module (the most common solution)
Set the default or conservative RAM timing.
Increase RAM voltage level.
Reduce the CPU voltage level.
Apply a BIOS update to fix incompatibility issues.
Mark address range as "bad"

My guess is it would be showing in Private Bytes since that is ram + page file, and this all seems to happen in virtual memory, not physical.

I don't think there is a better possible answer than this, it is simply a different way of counting, and if free -m is giving a decent amount of free ram then I wouldn't worry about it too much.

Here are the tips
  1. Replace the RAM modules (most common solution)
  2. Set default or conservative RAM timings.
  3. Increase the RAM voltage levels.
  4. Decrease the CPU voltage levels.
  5. Apply BIOS update to fix incompatibility issues.
  6. Flag the address ranges as 'bad'
