Product: Elitebook 820 G3
Operating System: Microsoft Windows 10 (64-bit)
Hi, what's the max allowable ram capacity of Elitebook 820 G3, 16 or 32Gb?
If the limit is 16Gb, can I use a single slot of 1x16Gb leaving one slot free?
Can I use 2666 or 3200 MHz?
Thanks

Hi,
Max RAM for the machine is 16GB DDR4 2133MHz RAM (2x8GB)
It supports 8GB modules
You can insert faster RAM, however it will run at 2133MHz
