Dell latitude E5570 memory upgrade not detected.

Hi,

I hope someone can help me with a compatibility issue I have when attempting to upgrade the RAM in my Dell Latitude E5570 Laptop from 8Gb (2 modules) to 16Gb.

I used the Crucial Scan tool to analyse my laptop and it produced the following as being compatible with my computer.

Crucial 16GB DDR4-2400 SODIMM  CT16G4SFD824A

Unfortunately, it was out of stock at Crucial, so I bought locally from one of Crucial’s recommended suppliers, Amazon.

When I fitted it to my computer it indicated that I had “invalid memory installed” (the lights flash with 2 orange and 5 white).

As far as I can determine, it’s the same as that recommended in the Crucial website.

I am at a loss to understand what's wrong with this but perhaps I'm missing something with the exact type of memory that’s suitable for my Laptop, and I can find no settings in BIOS that are appropriate.

I will be grateful for whatever guidance anyone can provide me with as, at the moment, I’m about £60 out of pocket for a product that is useless to me.

The following is an extract from the Technical specifications in the Dell Latitude E5570 Owner’s Manual:-
