Upgrade RAM

[Vlotho]

Hello,
I have a pc with windows 10 with 4 GB of DDR3L RAM and I would like to increase it to 8 GB.

I added a 4 GB DDR3 module and the BIOS does not detect it.
I got a message telling me that the module is not installed.

The motherboard normally supports DDR3L by default, and the one installed so far was DDR3.

Is it possible to make these 2 bars coexist?

I looked in the BIOS but I don't see any particular option for setting the RAM.
The BIOS was recently updated.

driverscloud and cpuz correctly detect memory in windows 10, but not BIOS.

Regards

@Vlotho,

Welcome to our HP User Forum!

Your HP Pavilion 550-158nf according to: https://support.hp.com/us-en/document/c04826646

 and: https://www.crucial.com/compatible-upgrade-for/hp---compaq/pavilion-550-158nf#memory, can be fitted with up to 2 x 8GB of DDR3L PC3L-12800, 1600 MHz, Non-ECC, UDIMM, 240-pin RAM

Preferably you should install matching/identical DDR3L RAM sticks.

Hope this was helpful.
