Hi guys,
I have bought HP Probook 440 G9 for my employee.
So I had to upgrade this laptop ram from 8GB 1stick to 8GB with 2 stick on it.
DIMM1: Current ram is Micron 8GB 1rx16
DIMM2: Empty
Then I bought this ram
1. Crucial 8GB 1rx8 2400
2. Kingston 8GB 1rx16 3200
Based on my research (as far as I know) both are identical except the 1rx8 and 1rx16
So when slot in these each one of these. Only Kingston unable to load in. Just a black screen.
DIMM1: Micron 8GB 1rx16
DIMM2: Crucial 8GB 1rx8
Boot up.
DIMM1: Micron 8GB 1rx16 3200
DIMM2: Micron 8GB 1rx8 2400
Boot up.
DIMM1: Micron 8GB 1rx16 3200
DIMM2: Kingston 8GB 1rx8 3200
Did not boot up.
I even slot this Kingston only to see if it work or not.
DIMM1: Kingston 8GB 1rx8 3200
DIMM2: empty
Did not boot up.
Then just to confirm on this, I slot in another type of ram
1. SK Hynic 4GB 1rx16
DIMM1: SK Hynix 4GB 1rx16 2400
DIMM2: SK Hynix 4GB 1rx16 2400
Boot up.
And works perfectly. No issue.
Then I though maybe the Kingston had some issue, so I try to put in on other device (DELL). Surprisingly it work!
I'm not sure if there any other requirement for the ram. As far as I know, it support dual channel up to 3200. Didn't really mention about the brand. It just say use the same brand if more than one ram.
All volt is at 1.2

Hi:
All I can say is that the Crucial memory report for the 440 G9 indicates that this is the compatible 8 GB memory chip you need:
Crucial 8GB DDR4-3200 SODIMM | CT8G4SFRA32A | Crucial.com
Crucial memory is the consumer retail division of the Micron memory company.
