RAM update issue HP Pavilion Desktop PC 595-p0125no

[KrisuBass]

Hi there.

I bought this one around 3 years ago: https://www.verkkokauppa.com/fi/product/574888/HP-Pavilion-Desktop-PC-595-p0125no 

- Memory: 8 GB (1 x 8 GB) DDR4-2666 (one free slot)

I have tried to upgrade its memory by using two of these: https://memory.net/product/mta8atf1g64az-2g3-micron-1x-8gb-ddr4-2400-udimm-pc4-19200t-u-single-rank-...

and with this: https://www.verkkokauppa.com/fi/product/722144/Kingston-FURY-Beast-DDR4-3200-MHz-CL16-32-Gt-muistimo...

Both are same size (physical) DDR4 as the original, but for some reason neither of them does not work. Physical installation has been done as should, basicly it is not a brainer due cant install them wrong. 

I simply cant boot up my computer with these new RAM modules. Computer gives that beeb code that refers to RAM issues. To be honest, im not sure why these new modules wont work. When i take new modules off and put original back, everything works as should.

Hi:

The first memory chip doesn't work because it is DDR4-2400, and your PC uses DDR4-2666 CL19 memory.

The second memory chip doesn't work because the CL16 timing is way too fast.

Your notebook uses 'standard' memory.  Don't buy performance memory.

If you are going to install DDR4-3200 MHz memory, it needs to be CL22.

You probably only need to install one compatible memory chip in the empty slot and use the 8 GB chip that HP installed.
