Add additional RAM to All-in-one

[WorkAlready]

I am trying to find out whether I can add additional RAM to my All-in-one 27-d0230z HP computer. It currently has 16GB of 3200 MT/s RAM.

The steps outlined to determine this on the HP website are WRONG, or at least out of date and inapplicable to my specific machine, and are utterly of no use. HP wants to charge me $79 to answer this simple question which is completely ridiculous. I'm willing to buy someone a cup of coffee if they can be of assistance. Thank you.

The specs don't indicate how the 16 GB of memory is configured...2 x 8 GB or 1 x 16 GB.

I was able to find this unofficial document which indicates the PC comes configured with 2 x 8 GB of memory.

You can run this command as administrator in Windows Powershell to determine how much memory the PC can support:

Get-CimInstance -ClassName Win32_PhysicalMemoryArray | Select-Object MaxCapacityEx, MemoryDevices

A PC with an AMD Ryzen 7 4800H processor should be able to support 2 x 16 GB of memory.

Cost-wise, it is not a good time to be buying memory.

Thank you so much, Paul. I ran this command in Powershell, and using the converting factor that I have since come across in your earlier reply to a different user's inquiry, it appears that my unit can support 32 GB of memory. If indeed I currently have 2 x 8 GB and not 1 x 16 GB, it seems that I would have to acquire two 16 GB modules, or could I merely swap out one of the 8 GB modules for a single new 16 GB unit?

I already owe you one cup of coffee. This would double that commitment. Thank you in advance.

You're very welcome.

Yes. you can remove one of the 8 GB memory chips, install a 16 GB memory chip and have 24 GB of memory running in single channel mode.

In order for the memory to run in dual channel mode, it has to be installed in matching capacities in each slot (2 x 4 GB, 2 x 8 GB, 2 x 16 GB).

Memory running in dual channel mode in equal capacities provides slightly better performance than when it runs in single channel mode.

In other words, 2 x 8 GB of memory will perform better than 1 x 16 GB of memory.

You would not be able to compare 2 x 8 GB of memory in dual channel mode against 24 GB of memory in single channel mode. 

More memory in single channel is probably better than less memory in dual channel.

Thank you, once again, Paul. You not only provide valuable information but you explain and outline it well. 

I followed your prior link to the replacement memory modules and, yes, they are pretty costly. The last time I looked into this-- some time ago-- I seem to recall that they were significantly cheaper. It appears that Moore's Law, or whatever the theory, is not holding. Perhaps these high prices are the result of the Trump Tariffs.

You're very welcome.

The high memory prices are due to these AI data center projects that high demands for memory chips.

As AI Eats Up The World’s Chips, Memory Prices Take The Hit

The manufacturers can't keep up with the demand, and the prices have skyrocketed over the last 1.5 years.

In January of 2025, that 16 GB memory chip was around $32.00.

Thank you for clearing that up. The article lays it out well. I'm not sure that I can wait until 2027 (or beyond) to upgrade my system but at least I know the reason why the wall is a little higher to climb.

Anytime.

Glad to have been of assistance.
