Upgrading the memory size of my RAM in my HP Elitebook 8440p

[Cossi2]

Hi there!! I want to upgrade the Memory RAM of my laptop HP EliteBook 8440p running with Windows 10 64 bits.

It has an Intel Core i7 620M.

It also comes with a HP Mainboard 172B as CPU-Z software reported.

It also comes with:

Module Numbers: 0 and 2

Module Size: 2 GBytes

Memory type: DDR3 SDRAM

Module type: SO-DIMM

Memory speed: 666.7 MHz (DDR3-1333 / PC3-10600)

Module Manufacturer: SK Hynix

Module Part Number: HMT125S6TFR8C-H9

This information as reported HWiNFO64 software.

I have already bought two Kingston Memories and I installed in the laptop and they didin't work.

The Kingston model is : KVR13S9S8/4 and the size is  of 4 GBytes.

But the machine was always in the loop of trying to start and load windows and turn off always. I want to know if there is any possible way that these two Kingston's Memories could work with my laptop and if they didn't? wich  4 Gbytes memories can I buy to work fine with my laptop. Also to verify if the maximum RAM size that I can get in this machine is 8GBytes as reported in the HP specifications web page?

Thanks for your help and I'll be waiting for your comments!!

Hi:

You have to install very specific memory for your model.

It has to be PC3-10600 (1333 MHz).  It has to have 8 little black memory chips on each side of the circuit board, not 4.

It must be 1.5V, not 1.35V.
