Acer Aspire 3 (A315-31)

N4200, 4Gb (DDR3L RAM, 1600), SSD

 

Acer Aspire 3 (A315-51)

i3 7200, 6Gb (DDR4, 2133), SSD

 

These both models are pretty new ones (Q2+ 2017), I don't find RAM support for either of these laptops (I found RAM support page for A315-21 model from Kingston websites... none of my models)

 

i3 7200 model support up to 12Gb RAM (4Gb soldered + RAM slot), and N4200 up to 8Gb, or so I heard from seller (verkkokauppa.com)

 

I have very bad experience with laptops and changing RAM, as usually RAM support legs get loose after just few changes (depends on models of course, but in general...)

 

Are any of these RAM sticks good for those laptops?

 

For i3 7200?

HX421S13IB2/8 (DDR4 SODIMM, 2133MHz)

KCP421SS8/8 (DDR4 SODIMM, 2133MHz) <- This is supported by A315-21 model!

 

For N4200?

HX318LS11IB/8 (DDR3 SODIMM, 1866MHz)

KCP3L16SD8/8 (DDR3 SODIMM, 1600MHz) <- Supported by ES1-533 (N4200) model!

 

https://ark.intel.com/products/95592/Intel-Pentium-Processor-N4200-2M-Cache-up-to-2_5-GHz

 

"Memory Types DDR3L/LPDDR3 up to 1866 MT/s;"

 

And could you update CPU microcode / Improve more performance for N4200 A315-31 model too? And also i3 7200, improve performance on next BIOS update?

    I suggest that you contact crucial dot com with a live chat. They seem to be currently testing compatible RAM upgrades for some of these models but testing is obviously NOT complete. BIOS-supported maxRAM might be even higher than you found using the latest 16GB DDR4 modules but, as with the 8GB modules you asked about, no 100% guarantees they will work. Performance improvements expected from future BIOS updates aren't available at this time.

    Asked via crucial com live chat, but they answered there is currently "glitch" with memory support pages on these models, and they don't show many RAM options or at all.

    >>>they don't show many RAM options or at all.>>>

     

    I'd guess that's mostly because it's the only option that they've found so far certified as compatible with soldered memory, not simply a glitch in pages.  Jack E/NJ
