Hello i want o upgrade my ram,CL22 or CL 20

[ShawWT]

hello everyone

my CPU  :AMD Ryzen 5 5600H with Radeon Graphics 3.30 GHz  3300hz

I want to upgrade my Ram,I checked Kingston,it recommended me to buy 

DDR4 3200MT/s Non-ECC ungepuffertes SODIMM CL22 1RX8 1,2V 260-Pin 8Gbit

but i found the other one 

Kingston FURY Impact SO-DIMM DDR4 3200 MHz 16 GB 2 x 8GB CL20 

the only difference between them is the CL number,Can I buy the second one ?

Hi:

I don't recommend the CL20 memory unless that is what HP installed in your notebook, which I highly doubt.

The memory HP installed is most likely CL22.

Why I don't recommend the faster latency memory...If your notebook's BIOS cannot automatically adjust to the faster CL20 timing, then the notebook won't boot up.

The BIOS is locked down as far as making any manual adjustments for the memory timing, and whatnot.

Is it worth the risk of using the faster CL memory?  That's up to you.

You can run the free utility that I zipped up and attached below and it will provide the information regarding the memory that HP installed.

it is CL22,

I think I will choose the safer way ,Thank you for the useful anwser! !!
