Pros: Purchased a slew of these and installed them in several HP ProLiant DL380 G7 servers, 4 kits per server. Everything works fine and no problems yet.

Cons: None.

Overall Review: No heatsinks on the DIMMs but there was no noticeable increase in temperature - granted this may be because they are installed in rackmount servers with good airflow. Newegg did a really good job packing them securely.
