@Nayan360 

 

Please use page 44 of the following manual

 

              http://h10032.www1.hp.com/ctg/Manual/c04887250.pdf

 

Do you know its existing RAM is 1x8GB or 2x4GB ?

 

(a) If 1x8GB you can simply add 8GB more to slot 2,

(b) If 2x4GB you have to replace BOTH slots with 2x8GB

 

You can use part # on page 44 or use the following compatible RAM (will run at 2133MHz)

     8GB:     https://www.crucial.com/memory/ddr4/ct8g4sfs824a/ct8098171

   16GB:     https://www.crucial.com/memory/ddr4/ct2k8g4sfs824a/ct8098147

 

Regards.

I did say

 

    You can use part # on page 44 or use the following compatible RAM (will run at 2133MHz)

 

You can use 2666MHz or even 3200MHz but machine will run at 2133MHz.  Of course you can always use 2133MHz RAM if compatible.

@Nayan360 

 

The best option is to buy same existing RAM (a tool called CPU-Z will tell you what it is). For different brand, you need same Timing configuration otherwise it won't run as dual channels.
