how many slots for ram do i have - CRI-S3 USB 3.0 internal reader | Axagon - axagon.eu slot mega 888

Hi I have an ia64 HP Server rx6600 machine I would like to find out how many empty disk slots are available on the machine.

I have a 4 GB DDR3 soldered RAM on my laptop.ASUS recommended maximum RAM is 8GB. How do i upgrade to the asus maximum recommended RAM? CAN I JUST BUY 8GB DDR3L-1866 SODIMM or 4 GB DDR3L-1866 SODIMM?

The number of RAM slots you have is the same as how many DIMM slots you have, so what you actually need to determine is how many DIMM slots you have.
