Memory replacement for Laptop Acer Aspire 5 A515-57-727C

leandroct

I bought an Acer Aspire 5 A515-57-727C Laptop. Although it has a good CPU, the memory and SSD configurations are very weak, as if it was already made to be cheap so that the buyer can upgrade as needed. I bought 2 memories Crucial 16GB DDR4-3200 SODIMM 1.2V CL22, but they didn't work. Did I make a mistake with the purchase? Or are both memories faulty? Even putting in just one memory, it didn't work. Returning the original memories (2 x 4GB PC4-3200AA-SC0-11) it works. What is this AA from the original memory? Thanks.

That is weird, Kingston recommends that same RAM: https://www.kingston.com/en/memory/search/model/105836/acer-aspire-5-a515-57xxx The CPU supports
Up to DDR5 4800 MT/s
Up to DDR4 3200 MT/s
So it must be the RAM controller or BIOS, have you updated BIOS to 2024/03/26 version 1.27?

No. I never updated the BIOS. It's v1.24. Do you believe this could be the cause of the problem?

So, I updated the BIOS to the newer version (1.27), but the problem remains.

The “AA” suffix doesn’t have a universal meaning but is likely a manufacturer-specific (Samsung?) designation.
Return the 2 modules to Crucial and ask for another set non-ECC standard JEDEC modules.

I think the memories was with problem. I bought another Crucial (CT102464BF832B 16GB DDR4-3200 SODIMM 1.2V CL22) and it worked.
