Hi,
I have a Lenovo W530 that is loaded with one Hynix 4MB DIMM: "4GB 2rx8 pc3-12800s-11-11-f3".

I understand from posts such as http://www.tomshardware.com/forum/327619-30-what-frequeny that this is 11ns CAS latency.

There are three spare DIMM slots, and I wish to install another 8-12 GB.

Questions:
1. Will I see an improvement by installing either faster RAM or RAM with lower latency?
2. Do I need to install the RAM in any particular configuration to take advantage of additional RAM?
3. Will it matter if I have an 'odd' number of slots filled (eg an additional 2x4GB which gives me flexibility to add an 1x8 GB later if I need it).

Many thanks,
Darren

1: Yes depending on what you're doing. 8GB is great for games.
2: It's best to go with dual-channel or whatever the motherboard supports.
3: Do not mix RAM. Get a complete set, such as a dual-channel 2x4GB kit.
