Windows 10: Is it decreased the bus ram when installed physical ram with 2 different ranked ram?

Hi everyone, who read this post, I have a question about the ranked ram. I hear my friend's talking about the system when he installed 2 physical ram bus 3200 with 2 different ram about the ranked ram. He installed 2 ram: 1Rx8 and 1Rx16, the PC said the bus for 2 ram is 2993, it's not got total fully the bus ram although both 2 ram is same as the bus. Everyone can explain this problem? Thank you.

Windows shows 8GB RAM installed but 4GB RAM is usable

Hi There,

I've just upgraded my pc from 4GB RAM to 8GB RAM. Windows seems to have detected this upgrade but why does it show as only 4GB RAM available. The following is what I have tried so far with no luck:

• I have tried the msconfig method on ensuring maximum memory is not checked.
• physically removed the new RAM and reinstalled it

Any thoughts/suggestions on how i can resolve this matter?

Thanks

 

Installed physical RAM vs Total physical RAM

Hello everyone,

I tried to install 16 GB of RAM to my computer, instead of the initial 8 I had. But when I add the new RAM (in total 4x4 GB of RAM, and they are the same kind). the installed RAM increases to 16 but the total physical RAM hence the total usable RAM remains
8 GB.

I want to point out, I am NOT talking about available physical memory, but TOTAL, compared to installed.





(Sorry the system is not English, but this is a screenshot from System properties so the titles follow each other the same way.)

I have a 64-bit Win 10, so that is not the issue.

BIOS sees all four modules, and there is no indication that the GPU uses the extra memory.

Tried to change the paging file size, but didn't help.

I am at a loss. Especially because only appears over 8 GB of memory, no matter which module goes into which socket.

Thanks in advance, hope someone can help.

Cheers,

Matt

 

How do I find the Usable RAM on a Surface Laptop 2?

I need to be able to find out the "Usable RAM" on my Surface Laptop 2 in order to ensure it will be compatible with the download of some exam taking software. Under Device Specifications, it lists the Installed RAM as 8.00 GB, but no Usable RAM is listed (having done some brief research, Installed RAM and Usable RAM appear to be different). Under System Information, it states Total Physical Memory of 7.92 GB; is this what Usable RAM is? Under System Information, there is also Available Physical Memory, but the number of GB listed under Available Physical Memory varies with each program I open. I'd be very grateful for any guidance anyone can provide.
