Patriot Extreme Performance 2GB PC2-9600 DDR2-1200MHz Review
 

Now this is the part that excites me. I love being able to see how far you can push a piece of hardware past its rated limits. However, this is also where I was disapointed. No matter how hard I tried — and I tried for hours — I could not get this memory to go beyond 1200MHz. I upped the voltage to the breaking point of safe limits, I loosened up the timings to see if it would be stable ... but no matter what I did, the memory would not pass memtest86+ for me to even try to boot into Windows without hosing my system. I was expecting even a little overclock, but nothing, not even 5MHz. I would expect for being an "Extreme" set of RAM that it would be able to overclock easy, but this was not the case.
