techPowerUp posted a review on the Mushkin XP2-6400 2 GB CL4 Kit

Mushkin is well known for the solid memory kits they make. Today we have the Mushkin XP2-6400 2 GB on our test bench. These modules are specced to run at DDR2-800 at CL4. With a price of $150 for 2 GB this kit is sure not the cheapest, but it comes with Micron D9 memory chips. In our testing we saw very nice voltage scaling up to DDR2-1136 at CL5.
