Problem to upgrade Dell 5531 Latitude RAM with Kingston Fury Impact 64GB (2x32GB) / 5600Mhz / CL40

Hello,

My previous thread is below, mentioned it was possible to use: (2x32GB = 64GB) in "Dell 5531 Latitude": Crucial 32GB DDR5-5600 SODIMM CT32G56C46S5

Now I have bought below RAM instead which looks the same in specifications, I think?

Kingston Fury Impact 64GB (2x32GB) / 5600Mhz / CL40

The green memory card is the 16 GB which works and came with the laptop.

The black memory card is the Kingston Fury Impact 32 GB 

However, when I insert those 2x32 GB in my Dell 5531 Latitude below happens:

1. The computer recognices that more memory is inserted (From 2x16GB to 2x32GB). I click on the button Continue.

2. In BIOS, it shows as in below image:

Memory installed: 65536 MB

Memory Speed: 4800 MHz

As the memory do have 5600 MHz, it seems to automatically have clocked down to 4800 MHz which was my original intention as I know Dell 5531 Latitude only can use Max 4800 MHz.

3. Until here. It all seems fine. But now I get erros like below images. I think the images shows best the errors that do occurs and mentions:
- Memory errors detected. Limit exceeded. Additional errors will not be healed. Location: BANK 0 (DIMM 1), BANK 0 (DIMM 2)

- Hardware problems were detected. To identify and repair these problems, you will need to contact the computer manufacturer.

4. I also tried to only insert 1 Kingston Fury Impact 32GB / 5600Mhz / CL40 but the same error happens with 1 card also.

5. When I insert the original 2x16 GB Cards again. The computer restarts as usual.

I wonder if those: Kingston Fury Impact 64GB (2x32GB) / 5600Mhz / CL40

should work and if so what can I do to make them work?
If they are not compatible. Why is they not compatible?

Kind Regards

Andreas
