Acer aspire a515-43 RAM upgrade issue

SPhaze

So I have an acer aspire(a515-43) which came with 2 sticks of 4gb 1RX16 PC4-2666V and have decided to upgrade to 16gb (2 x 8gb sticks 2666V). Everything went smoothly when putting them in but I loaded it up when I was done putting the 2x8gb sticks in and it still says I’m only running 8gb of installed RAM at a speed of 2400Mhz and not 16gb even tho I have both 8gb sticks in it. I’ve tried most solutions I could find on the internet but none have worked. Have I done something wrong or bought the wrong sticks or something? I bought the 2x8gb 2666V sticks as my 2x4gb ones that was in the laptop when I bought it was also 2666V. 

I haven’t tried opening the laptop back up to check anything since putting them in so if I can do anything on that part then please let me know.

Hi,
Could you please post the model name of the new RAM modules, if they are XMP  profile modules you may have bought the wrong type, if your CPU is like Ryzen 7 3700u, it amy have the restriction of 2400MHz maximum frequency, have you tried the modules one by one? If you haven't, give it a try because one of them may be a faulty module.
Download and install CPU-z and check the specs of the modules in Memory tab and SPD tab.

I’ve not long got home from work so I thought I’d try the simple thing of trying them individually first to see if one of them was faulty and they both showed 8gb of ram, then put them back in together again and both of them worked so I have sorted it. Thank you for your help!
