NITRO 5 AN515-43 Not able to use my full ram please help me to fix?

Akashkumar47 · December 2022

hi

This laptop was originally having 2gb of hardware reserved memory which let me to use only 5.9gb of 8gb ram

I thought because of one slot is empty its like that but now as i have bought another ram which is the exact same as the older one , i even cross checked with all the number its the same speeds too,

but now the hardware reserved memory has gone to 10.1gb is this a joke??

out of 16gb i have usable memory of same 5.9gb

[Edited the thread to add model name to the title]

Hi,

Could you please post the full model name of the laptop, specifications or model name of the memory modules as well, download and install CPU-z, run it and post the pictures of Memory tab and SPD tab for both slots.

In the meantime, go to Start and type RUN, type msconfig and click OK, move to BOOT tab and select Advanced options, check whether there's any tick in the box for Maximum memory, if not, tick the box and see whether it resolves the issue.

HI

thanks for replying

MY LAPTOP MODEL IS ACER -NITRO 5 AN515-43

It has a nvidea geforce GTX 1650

i have installed and took the snaps

this is slot 1 SPD

this is slot2 SPD

that is all , please help me fix this i have changed the msconfig setting and there was no tick so checked the box and it showed 16gigs i clicked ok and applied it.

And it did not work the hardware reserved memory is still 10.1GB!

I went to some nearby shops for advice too they said a reset of os would solve it like resetting the windows , iam running a windows 11 64bits 21h2 , so if i either reinstall this windows or i go back to the windows 10 , thats the way they said...

please do help..

Hi,

This happens mostly in AMD based system, hardware reserved memory will be released when your system needs more memory, so you can try removing the modules and wipe the pins with a soft cloth and reinsert them, you can also try swapping the RAM modules in the slots.

If your laptop works without any sluggishness,I would suggest you to continue to use the laptop without paying attension to RAM.

You can also try removing the new RAM and check the hardware reserved amount for 8GB, then remove the old RAM and insert the new RAM and check the reserved RAM, I think AMD based systems manage Memory in a different manner than Intel systems.

So does that mean my current laptop will use the ram when the usage of ram is 100 ??

You can see from the links I posted in my previous post that so far there's no solution found for this issue, you can try running memory intensive programs and test the RAM usage in Task Manager, open as many tabs as possible, watch youtube and open office programs etc. and see how the memory is allocated in Task Manager, my understanding is that the system will release the memory when and if the programs require more memory.
