Pros: Recently upgraded to a 4GB set of this RAM. Easy to install on a P5N32-E SLI Plus motherboard. Performs very well.

Cons: Figuring out the timing settings. Go here to find about timings and compatibilty answers: http://www.houseofhelp.com/forums/forumdisplay.php?s=86c8c20bad95bc7cb944edd2c2c86634&f=130

Overall Review: If you are using 4GBs of this RAM use these BIOS/timing settings: SLI memory = disabled Memory Voltage = 2.0V NB Core Voltage = 1.4V tCL = 4 tRCD = 4 tRP = 4 tRAS = 12 Command per clock = 2 tRC = 24

Pros: Easy to install...keeps my 2x quad core Xeon E5420s around 38c to 42c idle...

Cons: I get about same cooling effect from the stock passive heatsinks in my 4U server case...

Overall Review: I don't know if the ambient temperature is too high, air flow problems or what but I do not see a difference in the cooling power of these HSFs. I'm also using the Arctic Cooling MX2 thermal paste.

Pros: Very fast processor. I upgraded from a E6600 processor and I can notice the difference even from a slight upgrade. It was easy to install too.

Cons: none

Overall Review: Runs very cool with the ARCTIC COOLING Freezer 7 Pro heatsink/fan.
