Dedicated Memory not being used

[Tet333]

I had this computer for 3 years now, but it was only now did I realise that nothing is using my dedicated memory!

It's set to be 128 MB of dedicated GPU memory but it's always at 0 and no program uses it.

128 MB from task manager does not correspond to TSG output which says 1024 MB
It's probably safe to assume it's either:
1. Driver issue
2. This feature (in task manager) is relatively new

Try this driver and restart computer:
Download Intel® Graphics Driver for Windows* [15.40]

Thanks for the driver, but I already had it installed. I did reinstall it and restarted my comp but it still isn't using the dedicated memory, any reasons why?

Very likely it IS used just fine but task manager is not updated for some reason.
Since task manager shows only 128 mb (instead of 1024) which is wrong it's likely a bug with task manager.

IF you want to ensure that this is indeed a bug, then follow these steps:
1. Download process explorer from the link below:
Process Explorer - Windows Sysinternals | Microsoft Docs

2. Run procexp64.exe as Administrator
3. Click on menu: View -> System Information
4. Click on "GPU" tab

Here you can see amount of dedicated memory and usage

Uhh, there seems to be a small bug...

That's not normal right?

I don't know what to say..

There are 2 Intel tools which you can use to verify whether your GPU is wrong or
there is an issue with Windows:
Download Intel® Graphics Performance Analyzers
Download Intel® Extreme Tuning Utility (Intel® XTU)

Make sure to be careful with XTU, ex. not to overclock anything, you just want to verify memory usage if there is such option.
