I see the 4 memory slots. However, regardless where I installed my new pair of G.Skill 8GB, the system info. only registers 4GB. Do I have to update newer version of BIOS? Thanks in advance.

There are 4 slots. After reading an online manual, I realized that you have to install DIMM in the black slots first. Now it has 8 GB.

Is the maximum memory capacity really 4GB? That seems too little. Thanks.

according to HP web site max memory is 16GB
