The Mushkin XP2-6400 is the first 2x2GB memory pack we tested in our labs. With the arrival of VISTA, the need for extra memory has become a necessity. Mushkin XP2-6400 can become your next best friend if you're looking to buy 2x2GB memory modules, offering superb performance with 4-3-3-10 timings at 400MHz.

According to our tests, the memory reached 562MHz with voltage up to 2.3V! That's almost 162MHz higher than what Mushkin advertises for the product. It's very possible with higher memory voltages, you can boost even more MHz, but it's not recommended. With lower, speeds you can have 1T at 333MHz, but this applies only to motherboards with Nvidia 680i chipsets.

Ending our presentation, we were very satisfied with the Mushkin XP2-6400C4 memory. Despite the fact that Windows XP and VISTA 32bit doesn't "use" the full 2x2GB memory setup, for 64 bit systems, the memory's performance is so good that you cannot really go wrong. With very high overclocking capabilities, we give this product our Editor's Choice Award.
