Pros: Lots of memory for a low price, maxed out my motherboard.

Cons: None

Pros: Love its ability to jump up to quad channel - if by chance I decide to drop it on a LGA 2011 chipset. Being a software developer with several different applications/remote connections/ development platforms open all the time. I never want to have to THINK about rebooting.

Cons: your friends may no longer think your cool when you take it to this level.

Pros: Wanted 32GB of memory for my personal ESXi server - if I ran 3 Win 2k8 servers at once I was nearly maxing out my memory usage (12GB of 16GB). This allows me to literally run everything until I bottleneck my hard drives. Next investment - SSD.

Cons: None so far.

Other Thoughts: My ESXi environment is primarily used for penetration testing training and things of the like. It requires me to run memory intensive VM's (Win7 / 2k8 / CentOS servers) and I couldn't be happier with this set of RAM.
