I strongly recommend G.Skill HZ series (see my signature).
Not only rock-solid stable, but apparently Micron D9's (never removed the heatspreader!), great bandwidth at stock 800MHz speed, and the specified voltage is only 2.0 - 2.1V. Ballistix and Patriots call for 2.2V, and supposedly might cause problems on motherboards rated at default 1.8 - 1.9 V. You might have to boot with another stick rated at 1.8V, change the timings/voltage, and only then install the 2.2V rated ones.
HZ's work great, at least on nForce chipset based motherboards.
