2.2gb Usable out of 4gb RAM.

Hello! I've just installed my windows 10 and since it was running slow on a 2gb ram, I decided to buy a 4gb stick on my 32bit system. Long story short, it only shows 2.2gb usable. 768mb(or something close to that figure) is reserved for the videocard but I think I still should have 1gb more. Ive tried the unchecking the maximum memory and didn't work. I've tried all possible solutions that I could find on the net yet no progress. Except for one, which is updating the BIOS, of which I am particularly bad at trying to figure out how. Anyway I'll just attach some of my computer information so if anyone could help me please. Thanks!

I'm not quite sure though I think no. Cpuid-z shows that my videocard uses 768mb, and I think 32bitsystems can only utilize up to 3.2gb disregarding that of the video card so I still should have 1gb more. OrOr am I wrong? Oh and also tried swapping slots, still didn't solve the problem

I had that problem on an older computer I upgraded to Windows 10 32bit. It had a 64-bit capable processor and when I installed 64-bit Windows 10 my useable RAM went up to 3.75 GB. I think you are stuck with 2.8 GB useable with 32-bit Windows 10.

Hi,

From MS:

Edition	Amount
Windows 10 Home 32 bit	4 GBs
Windows 10 Home 64 bit	128 GBs
Windows 10 Pro 32 bit	4 GBs
Windows 10 Pro 64 bit	512 GBs
Windows 10 Enterprise/Education 32 bit	4 GBs
Windows 10 Enterprise/Education 64 bit	512 GBs

So, assuming 1GB is allocated to the GPU then that makes it roughly 3Gb available to the OS (32 bit).
If you have two RAM slots on the MB you could add the 2 GB you pulled if its timings are close to the new one and by doing so you should seeing about 4GB available to Windows. Never tried this though.

Either that or installing the 64 bit version of what you're running now.

Can check how much memory is allocated to the GPU in BIOS as well ? If it's set to 1Gb you could try to reduce it to say 512Mb and see if the 512Mb are then reallocated to the OS.

Cheers,

From his OP, it doesn't look like his CPU will support 64-bit. Since my experience on the old computer I upgraded, I have corrected the advice I used to give out. I used to say, 4GB or less RAM just install 32-bit. Now my personal feeling is, if the CPU will support 64-bit, then install 64-bit.

His processor will support 64 bit (it shown on the system screen shot). I agree, the OP should be installing 64 bit Windows 10.

You are correct. My mistake, I read the screenshot wrong! Yeah - install the 64-bit Windows 10 for sure and the useable RAM will bump up to over 3.5 GB.

Hi,

Exactly. I feel the same way about it.

And his CPU also includes the AMD/ATI GPU so that explains some of the memory not going to the OS.
