Hi Everybody!
I have an Acer Aspire 5 A515-54G-53H6
I couldnt find data sheet about memory, information about specs or those things that appear everywhere in other models. Frustrated!
Could you help me?
I only found this thread:
But i need more information about dimm specs / support por socket. Where can i find it?
Hi @mjcasu
Negative; your slot 1 (bank 0 WMIC) has the Kingston DDR4, CPU-Z won't read the soldered DDR4, only monitors RAM slots (removable DDRs)
This is the DDR4 that is soldered on our MOBOs, WMIC Bank2, the 4GB Kingston DDR4 is in the removable DDR4 slot. The max. clockspeed of our MOBO is 2667 MHz if you have two identical DDR4s you are in Dual Channel mode (2666 MHz).
I have 2 idental 4GB Hynix modules (a515-54G 10th Gen. i7) like the picture above and if you click on the memory tab in CPU-Z you should see Channel # DUAL at the top right like this:
Ignore the frequencies above as that varies a lot with what you are running. To find your effective speed in Byte/second (copy/write/read) you need to download MaxxMem freeware. I get 28 GByte/sec. average speed that is more than the clock speed (2,667 MHz x 8 = 21,336 MByte/s). Not sure what speed you will get if you replace your Kingston 4GB for a similar 16 GB module. for sure the way you have it now will give you Dual Channel but when the two DDR4 sizes differ I hope that you still will get 2666 MHz (maybe less).
Question what on earth do have you running that uses 7.1 GB? I have my laptop 4 years now and use W11 22H2 with all the "bells and whistles" security, media and Office wise but my RAM use never gets above 4.2 GB (4.5 GB if I watch HD videos). Our MOBOs are the same and my CPU is bigger (i7), I have a 1TB mechanical HDD you probably have SSD.
Check Task Manager what is running. This model is not made for heavy games but for the "all round" users.
Do you have the option to look at your BIOS settings at the start of your bootup?
On the computers I have, Dells are F12, some of the older ones used esc or f1.
you should see the prompt at the beginning: You have to press whever key it is
at the very beginning, just as your computer boots up. it might be called "setup" or "bios"
Also, if you have your PC setup for "fast bootup" it may not show the prompt…
Good Luck!
Type/paste in the Command Prompt opened as administrator, that will give you all the specs of the DDR4 soldered on your MOBO and if there is one in the slot also:
wmic MemoryChip get Banklabel, Capacity, Configuredclockspeed, Devicelocator, FormFactor, Manufacturer, Serialnumber, Speed
I have the same laptop (2020) with only a 1TB HDD (no PCIe SSD) and has 1x 4GB DDR4 soldered and 1 slot was free so I bought an idental DDR4 as soldered on my MOBO
SK hynix HMA851S6CJR6N - VK Non ECC PC4-2666V 4GB DDR4 at 2666MHz 260pin SDRAM SODIMM
This gives me 8GB in Dual Channel 2667 Mhz
RAM can be upgraded to max. 20 GB, 2666 MHz is the max. clock speed, so if 4 GB is soldered you can buy 4, 8 or 16 GB modules for the free slot but only the 4 GB will give you Dual Channel: 28 GByte/s average R/W/C in Windows11 22H2.
Someone posted a screen shot of CPU-Z.
(Download CPU-Z)
Click on the Memory and the SPD tabs to learn your RAM size and Speed. (But not your Max RAM)
I have a newer model of the Acer Aspire 5, (i5). The RAM is DDR4-3200, but the set-up is the same. 4 GB of RAM on the board and 4 GB in the slot. You can add 8 GB or 16 GB, to replace the 4 GB dimm in the slot. But it only works in Dual Channel for the original 8 GB.
(4 GB on the board, plus an additional 4 to match that.) Whatever is above that works in Single Channel.
I added an 8 GB dimm, that I already had. (12 GB Total)
It would make more sense to put 8 GB on the board so you could match it for 16 GB of Dual Channel.
But it works pretty well for a laptop that is not very expensive.
Cheers!
Hello everyone. Thanks for your reply!
Here are the screenshots.
@osef I need to know what kind of memory and size can I buy and how much it supports. What kind of information could the BIOS boot give me? can i get that information with cpu z?
@Puraw Where can I find the information you mention? I couldn't find any official documents.
RAM can be upgraded to max.
20 GB, 2666 MHz is the max. clock speed, so if 4 GB is soldered you can buy 4, 8 or 16 GB modules for the free slot but only the 4 GB will give you Dual Channel: 28 GByte/s average R/W/C in Windows11 22H2.
Here is the command output.
@KanagawaTomasu Here is SPD information.
I only have information on Slot 1. Slot 2 is empty.

Thank you all!
Im going to install this memory: AD4S320016G2 MEM NT DDR4 16GB 3200

@Puraw Nice comment and question! XD. I test some systems with dockers, programming environments and many chrome/firefox windows with various components. I am clearly not a normal user. :) That's why I need more memory penalizing the Dual Channel support.
This machine is enough. It works great, but I need more memory. It only has a serious problem that I already asked in another forum about the support of Ubuntu + Windows on separate disks and also, there is no technical documentation available! I never found it.
I created a virtual drive (called Native Boot) once on my internal boot drive, not with Linux but cloned my complete Windows11 disk and the virtual drive booted perfectly like having 2 laptops. This was with my old mechanical HDD (no SSDs) RAM speed was 20 GByte/sec. average (read/write/copy). Here are the instructions, eleven forum has a current thread on the topic:
https://www.elevenforum.com/t/native-boot-windows-11-virtual-hard-disk-vhdx.611/
It has been reported that 16GB 2666 MHz will also work in Dual Mode with our MOBOs, let me know your speed, although my RAM use never gets above 4.5GB, I am a "Normal User"😀
