Pros: Put 8GB of this in my Gigabyte P55-UD4P and enable the xmp profile 1. Booted and it just works great. No issues. Great performance. What more could you want?

Cons: Heat sinks are a little tall and come very close to the CPU cooler. Might get in the way of some coolers.

Overall Review: By default this will run at DDR3 1333 on core i series. You have to enable the xmp profile to get the DDR3 2000 speed. Running 4 dimms in dual channel at this speed is hit and miss with any MB RAM combination but this RAM and the GA-P55-UD4P works perfectly.

Pros: Lots of ports. Has lots of sata, usb, 1394, audio, lan, and all the legacy ports on board. Good cooling. Well built.

Cons: Memory slots are a little close to the CPU socket and so the closest dimm is under the CPU cooler a little. Makes it a little more difficult to get all the RAM in.

Overall Review: This is a nice board with all the ports most anybody will need including a few legacy ports that very few will need (or even understand). All solid capacitors and heatpipe cooling give this board good stable power. I only have one graphics card so the fact that the 2 PCIe x16 slots share the 16 lanes is not an issue for me and shouldn't be a bottleneck anyway (standard on P55 MBs). I like this board a lot and would highly reccomend it (and have).
