PQI's certainly been making a name for themselves since coming onto the scene here recently, haven't they? Maybe this speed boost is just what the doctor ordered for DDR2...

"PQI’s TurboMemory memory modules officially capable of overclocking to 900MHz are to be available in 256MB and 512MB versions as well as 512MB and 2GB dual-channel optimized kits. The company guarantees successful overclocking with CL5 5-5-15 timings and 2.0V voltage, a significant increase over 1.8V default setting."
