Windows get maximum ram command

[Aryan Sharma]

If we write this command in cmd it will show you the maximum amount of ram supported by your device.I just wanted to know that you should trust your manufacturer's ram limit or you should trust this command

wmic memphysical get MaxCapacity, MemoryDevices

They both give the same result just in different units. 

EG. My system has 64GB of RAM and the command shows 67108864.

Convert 67108864 kb to GiB.

The result is 62.5GiB which is about the same.

You should only trust what you see with your eyes.

Open the case and look at the ram sticks. Either trust what's on the label, or read the part number off each ram chip and determine its size and go from there (for example 8 chips each of 8 Gbit = 8 GB ram stick)

 

That command reports what the bios reports  If the bios is screwed up or someone with bad intentions hacks the bios, an incorrect value can be reported.

 

edit: of course, this assumes we're talking about regular people using computer for personal use, all things simple.

Things get complicated if we're talking about virtual machines, your OS running in a virtual machine, memory reserved for hypervisors, memory reserved for integrated graphics or other things...

From what I see the point of the command is to display the max supported by the platform, not what's installed right now.

 

MaxCapacity  MemoryDevices
536870912    8

 

That's correct here, system supports 8x64 as per mobo manual.

So your laptop probably has a chipset and bios configured for maximum 2 memory slots, which means the maximum supported is 32 GB by the chipset and / or by the bios.

 

You either have a 4 GB + 8 GB sticks installed in the laptop, or probably the laptop has 4 GB of memory soldered on the motherboard and not-removable, leaving you with a single slot to insert memory into.

You may have a 8 GB stick installed in that slot, so you have a total of 4+8 = 12 GB or the bios says you can go to 12 GB by installing a 8 GB stick.

 

It's possible the laptop supports 16 GB sticks, but maybe when the laptop was made there were no such sticks so they couldn't validate or add support in the bios for 16 GB sticks.

can I go to 20gb ram

I don't know.

First I would figure out if I have two sticks of ram currently installed and if they can be both removed. If one stick is permanently soldered to the motherboard, you're only left with one stick to install.

Then I would check to see if I have the latest bios version for the laptop and I'd check the bios update notes to see if they mention any information about 16 GB sticks being supported. 

I'd try to find Memory QVL lists on the website of the laptop manufacturer, for the model of the laptop I / you have.  See if there's 16 GB sticks in the list of memory sticks tested.

If the manufacturer of the laptop has a Q&A section see if there's any questions about 16 GB sticks being supported.  If there's a forum section,

Last, it wouldn't hurt to give an email to the manufacturer and to simply ask if 16 GB sticks are supported. It may take a few days to get some answer.

I'd also check forums and I'd google my laptop's model / part number along with keywords like maximum memory etc and try to figure out if 16 GB sticks are supported.
