Fast reliable and zero compatibility issues with a Gigabyte P55 motherboard.
The heatsink, though very functional, can really hurt your fingers if you are careless around it as the edges are very sharp.
Though not the cheapest, an excellent memory. I have always been very impressed by corsair's ability to make highly compatible and reliable memory. This is no exception.

Experience: 2 Weeks

Good heatsink
Tall heatsink (incompatible with some CPU heatsink overlaping slots 1 and 2)
Fast memory, had no problems with those so far. The heatsink is very bid on it, so I guess it is good for overcloaking, but be warned, those wont fit on slot 1 and 2 if using Noctua dual fan heatsink on your CPU.

Experience: 3 Months

good memory, works great, very fast
I purchased 2 sets of this memory as part of my first system build. It installed and has worked flawlessly. One of the common questions, especially with the new core i7 CPU's is compatibility. I can say there has been absolutely no issues with this memory.

I highly recommend this memory for anyone purchasing the new i7 CPU's.

- Quick, good timings
- rock solid performance
- looks great
- heatsink is tall
Though not the cheapest, this memory performs great and looks just as good. Had no issues, XMP profile set it up perfectly. Recommended!

* Excellent RAM, Strong Performance.
* Very Good Cooling System.
* Very LARGE Cooling System
* Not Immediately Evident That It Is Supported In Phenom II Systems.
I picked up this ram when it was on for 130$ which is an excellent deal for some DDR3 1600 at CL8. The Dominator Series is Corsair's Premium Line and Corsair is an excellent manufacturer.

It should be noted a couple of things came up. First, I had to go to their site and use their very intuitive tool to get a list of all boards that these were guaranteed to work with. My motherboard (along with many others) was on the list, which is good. The product description lists this as i5/i7 memory though, and it works just fine with a Phenom II system, so that is not so good.

The other point is that these sticks will not drop  in and run at their rated speed. In my board they default to 1333 MHz at CL 9 at 1.5 V.

You'll need to up the voltage a bit (thus overclocking your on-die memory controller) to hit the higher frequencies. Keep that in mind.

The last point is that this ram is quite tall and *MAY* bump into any aftermarket HSF you have installed when placed into the first or second ram slot. This was the case in my board and thus they are placed into slots 3&4. Keep this in mind as well.

At the end of the day though, this is great ram.
