It is good to have tons of customization choices as a PC proprietor, however the lack of plug-and-play simplicity is simply too large an inconvenience to disregard. More often than not, your PC’s preliminary setup holds it again from reaching its full potential, and it’s a must to dig deep into your system’s settings to unlock the true efficiency.
One occasion of this regard is your PC not having the ability to totally entry its RAM. Now, I am not referring to the RAM speeds; the frequency limitation has turn out to be a well-covered matter locally. I am speaking about your system reserving RAM in your GPU’s reminiscence pool, which may make your system fairly sluggish.

I disabled one hidden Home windows setting and freed up CPU efficiency immediately
For those who’ve acquired an excellent CPU and do not thoughts some heat, give this a strive.
Wait, the place did my RAM go?
Process Supervisor informed me I had much less RAM than I paid for
The ceiling for RAM necessities is rising every day, as Home windows 11 turns into more and more demanding as an OS, pushed by the rising want for background processes and AI options. I acquired 2x8GB of DDR5 reminiscence for my system, pondering it was sufficient till it wasn’t. Once I opened Process Supervisor, I used to be shocked to see that solely 12.9GB of the overall RAM was accessible, which actually pushed me to research the trigger. Now, after some analysis, I discovered that your system’s RAM is being reserved in your iGPU.
Your system reserves RAM in your iGPU even with a discrete GPU
The iGPU (built-in graphics card) in your CPU does not even have VRAM. As a substitute, it depends in your system RAM as its video reminiscence. Now, you may suppose that this may not be a problem for you since you utilize a discrete GPU, however your system nonetheless reserves a portion of your RAM in your iGPU, regardless. Most PC house owners not often entry their system BIOS, which is why they’re unaware of this reality.
Fortuitously, you possibly can release the reserved RAM in your iGPU. Now, you possibly can go 2 methods — both cut back the reservation to the bottom setting or disable your iGPU utterly. To cut back GPU shared reminiscence, comply with these steps:
- Enter BIOS by urgent Delete/F2.
- Go to Superior/Chipset Configuration/Graphics Configuration.
- You may both see DVMT Pre-Allotted/UMA Body Buffer Dimension, relying in your CPU.
- Clicking that choice will permit you to change the system-reserved RAM in your iGPU — change to the bottom accessible setting.
To disable the iGPU utterly, this is what you will want to do:
- Enter BIOS by urgent Delete/F2.
- Go to Superior/Chipset Configuration/Graphics Configuration.
- Set Major GPU to PCIe, or should you can see an choice for built-in graphics, disable it.
Disabling the iGPU utterly means your PC will not show with out your discrete GPU. Typically, I like to recommend protecting the system’s reserved RAM in your iGPU at a decrease worth in case you might want to boot with out your discrete video card.
Different causes your RAM reveals lower than full capability
Sadly, not all lacking reminiscence is recoverable
Now, the iGPU has some reserved reminiscence that may be modified or disabled, however your discrete GPU maintains a shared reminiscence pool drawn from the system RAM, allotted by the GPU driver at startup. Throughout heavy workloads or whereas working demanding online game titles, your video card can entry this shared reminiscence pool when the VRAM is beneath stress.
Sadly, there’s not a lot you are able to do to vary this, so you could have to decide on your system settings properly when working a online game, or simply keep away from burdening your GPU an excessive amount of when performing any resource-intensive exercise.
Even with the GPU’s reminiscence reservation, your RAM utilization may nonetheless be decrease than the overall capability as a result of a few of it’s put aside for different {hardware}, comparable to USB gadgets, memory-mapped I/O, driver overhead, and so forth. Sadly, nothing could be accomplished to release this RAM, as it’s important for full performance.
I freed up efficiency — this is what modified for me
As I’ve talked about earlier than, 16GB has turn out to be the naked minimal for Home windows 11, and each megabyte issues to me as a result of this reminiscence is break up amongst working the OS itself, third-party apps, and generally video video games. I utterly disabled my iGPU and freed up a gigabyte of RAM — though outcomes could fluctuate relying on the pre-allocated reminiscence in your BIOS and CPU. Typically, you possibly can free 32MB to 2GB of RAM, relying on the configuration.
For somebody with an 8GB or 16GB RAM setup, this repair is admittedly useful. Reminiscence is already fairly costly, so it is essential to take advantage of it. Any extra measures you possibly can take to release extra RAM embody debloating Home windows by disabling companies you will not want. Moreover, Microsoft’s RAMMAP additionally helps purge cached reminiscence to enhance efficiency.
