PQI's DDR2-667 Is Fast, With No Overclocking Headroom

Previous Next
8:29 AM - 02/27/2006 by The editorial team

The PQI modules are double-sided, and they also managed to achieve CL3.0 timings at standard input voltage levels. This combination delivers very fast RAM for normal use. But they mustered only a weak showing in our overclocking tests: they topped out at a relatively modest speed of 888 (444 MHz). Other vendors manage to post much better results. That said, buyers can trust the label printed on these modules and enjoy fast CL3.0 timings.
