Pros: It's RAM.

Cons: I've had this is my system for over a year and I am anything but impressed.

I paired it with an Asus P5Q-E board and Intel Xeon X3220 chip (Server badged Q6600 for you n00bs). First, it only detects at 800, not 1066. It's not the board, I checked with my new Mushkin RAM, it was perfect. Second, it does not overclock, period. I pushed my chip from 2.4 - 3.6 and had to keep underclocking the RAM so it would work (Increasing your fsb speed auto increases DRAM on my board) Had to keep it at 800mhz to keep from BSOD on start up. After WAY too much tweaking, I got it Prime95 solid for 24hrs. Not impressed. . .

My other machine running an Asus P5Q - Pro board and X3220 chip is using Mushkin 800. I have the chip pushed to 3.6ghz as well and the RAM overclocked to 500mhz. Seems kind of backwards to me when I do the comparison. This machine is also 100% Prime95 rock solid for 48hrs!

Overall Review: What else is there? Buy the 800, it costs less. This will leave you scratching your head, at least I am. Corsair is a great company, I have a 850w modular power supply running my gaming rig and it's top notch.

This RAM was not what I expected it to be. If you want 1066 and overclockability, buy Mushkin's 1066 Blackline series. It's pretty serious. Worth the money.
