Hello.
My daughter have a old HP laptop with only 4 GB sdram, I want to upgrade it to 16 GB SDRAM and install Ubuntu-Mate on it.
4 GB DDR4-2133 SDRAM (1 x 4 GB) is in it today.
Can I install DDR4-2400 MHz SDRAM (2x8 GB)?
or
Can I install DDR4-2666 MHz SDRAM (1x16 GB)?
Cheaper for me to bye a DDR4-2666 MHz SDRAM (1x16 GB), then I can upgrade it with one more 16 GB later if we want.
Thanks.
