The thermal monitoring and LED control is ace, the running lights get my thumbs up but the active top LEDs just remind me of those light boxes wedding discos used in the 80's. Also really great that DDR3 is still getting some love rather than the same treatment DDR2 got.
Still I'd grab as much DDR3 as possible now, before to long the price will go mental.
I've been running an 8gb set of these for a couple of years now. Cant fault it and the LED's are not overpowering although they do flash like crazy whilst gaming. :crazy:
I'm running 4x4GB sticks of this stuff and I have no problems with it.
The XMP profile worked right out of the box and I'm running at 1866MHz 9-9-9-27.
I only have an InWin G7 case so the side panel is perforated and not a window but it creates a nice haze effect on the holes and at night it looks pretty cool when it beams on to the wall opposite my PC.
