In the article that you specified, the 66MHz etc. is referring to the older, slower RAM, not DDR.
Here's what HP says about the DDR for the 733uk:
DDR memory, or Double Data Rate memory, is a memory technology that doubles data throughput to the
processor. This type of memory dramatically improves the memory system's ability to service high
multimedia requirements, such as 3-D graphics.
Key features include:
double the amount of data by using the rising as well as falling edge of the clock signal for data
transfers.
significantly reduced power consumption: 2.5 V instead of 3.3 V.
memory bus runs at the same frequency as the CPU front side bus.
184 pin connection.
DDR 333
throughput of 333 Mb per second.
backward compatible with DDR 200 and DDR 266 devices.
The foregoing is copied directly from an HP site that I have access to, so ignore the slower speed
reference on the page you were looking at, OK?
