What is the maximum RAM memory I can upgrade my laptop to?

Hello everybody!

In the attached image I post my laptop's specifications (from Acer's own site).

It states that maximum memory is 20 GB . How can I update to this maximum memory?

Note (in linux with command line sudo dmidecode -t memory, I get misleading/contradictory information, as stated below)

Also, upon opening the lower end of the laptop, I can only see one memory 'stick' of 8 GB, which is the reported memory in the system (both BIOS and OS, linux and Windows), and only located (up until now, I mean) a single 'bank' for memory placement, which is taken now by that 8 GB memory stick.

So, I repeat, how to update the memory, to that aforementioned 20 GB maximum?

Thank you beforehand!!

Sorry no pointers. It's simple. Less than half the time it works. More than half the time it doesn't. Similar specc'ed mainboards with 8GB soldered RAM installed, recognize 24GB with a 16GB sodimm in the replaceable RAM socket. This suggests a fairly flexible RAM system. So you'd just have to try it and see. If it was mine, I'd probably give it a go from a vendor with a good returns policy.

Your mainboard should have one soldered unreplaceable RAM socket and one replaceable RAM socket. The unreplaceable soldered RAM socket might have 0GB, 4GB or 8GB installed; the normal configuration is 4GB soldered RAM. If you have 8GB then there would be another 4GB module in the replaceable RAM socket.

You can install up to 16GB DDR4 RAM module in the replaceable RAM socket. This would give a maximum of 20GB RAM with the 4GB soldered RAM.

This laptop has "On board Memory size 0GB /4GB" In addition it has 1x slot for removable memory and the stated memory for the A315-55G inot that 1x slot is DDR4-2133MHz or DDR4-2400 MHz, 1.2V, Standard JEDEC 260-pin, see the memory modules list sugested by Acer below and also you can run the Crucial System Scanner

If you have 8GB then there would be another 4GB module in the replaceable RAM socket.

You can install up to 16GB DDR4 RAM module in the replaceable RAM socket. This would give a maximum of 20GB RAM with the 4GB soldered RAM.

Hi, thank you for your answer.

When I opened the laptop case, I could see only one memory stick of 8GB.

This makes me assume that the onboard memory size could indeed be one of those size numbers you've mentioned. More precisely, 0GB.

Or is there something else to consider here?

If, there would be either 4GB or 8GB of onboard memory, the total amount of memory reported in the system would be 12GB or 16GB (respectively), adding up the memory size of that DIMM.

Correct?

Thank you again for your time and patience.

Cheers!

>>>When I opened the laptop case, I could see only one memory stick of 8GB.>>>>>>More precisely, 0GB.>>>

Yes, you are correct. So the maximum according to the original specs should be 16GB with a single 16GB DDR4 sodimm with 0GB soldered RAM. It is however possible that the BIOS and Windows might even recognize a single 32GB DDR4 sodimm but not guaranteed.

Hi again.

Thank you very much for your promptness.

One last thing.

Can you please give any pointers to your "claim" (let's call it like that) that, if I install a 32GB memory stick it could be recognized by the system? Because for me it would be awesome.

Thank you in advance!!!

Hi thank you for your information and even more for your honest disclosure.

I truly appreciate it.

Cheers!

See you sometime soon!

Let us know how it goes one way or the other. Good luck.

Surprised no none mentioned Task Manager . ctrl-alt-del and select. May need to hit "More details". Under the PERFOMANCE tag select MEMORY. Will say total memory, speed, type, and how many slots are used.

Hello @JackE

This is an update to your request for a follow-up on my laptop's memory upgrade OP.

I am not going to try a full blown 32GB update. Due to several constraints where the financial one does play the foremost role.

The others are in the lines of wanting to do that upgrade in the upcoming days and, since this is a weekend and most of the stores where I live are closed -- and this makes it difficult to get personalized information about their return policies in case the 32GB upgrade wouldn't play along as wished -- I am playing on the safe side, and I've decided to purchase a 16GB, 1200.0 MHz ( DDR4-2400 / PC4-19200 ) from Crucial, which happened to have a discount promotion in an Online Retailer in the nearabouts...

So this is pretty much it.

Only thing missing here, in this path I've chosen, is to update all this thread with the information about the memory installation and whether that plays well enough or not.

Until then, all the best!

Cheers!

I buy almost everything from either Amazon or eBay. Return policies are easy to get. That said Crucial is good but know shipping charges and time up front.

Note crucial also has a pretty neat system analysis app that will tell you exactly what you need.

Hi, thank you for your input.

Well, as posted in other sites, and I think I can confirm that myself, since I've opened up the casing and there was only one slot available for memory upgrading -- although, from the software perspective, everywhere I looked it said that I had two banks of memory -- there is no guaranteed way that all the software that I have consulted, would give me a 100% answer to the OP question, which was, to determine the upper limit of ram that my system would take.

Meanwhile, @padgett your suggestion is very much welcome, since it sort of gives a nice shortcut to rapidly getting information about the hardware in question, memory.

For that reason, I've liked your contribution as well.

Cheers!

Ok.

I've purchased from those sites/stores as well, but this time I've chosen an even more near retailer.

And you're right off course. To know those policies up front is essential.

BTW many Acer Laptops are like that, usually 4GB soldered in and one slot for "More". I usually add another 4gb since have never needed more than 8GB. First upgrade I did was a 384kb card to increase a 256k machine to 640k(max), been building computers for a while but know nothing about gaming past Flight Simulator.

Hello everyone!

Problem fixed.

I've made the upgrade and now the laptop has 16GB of total physical memory.

The purchased memory stick is working ok.

It was a Crucial 16GB DDR4 2400 SODIMM CL17.

Thank you all for your kind information!

Cheers!
