Samsung DDR2-667: Conservative RAM Sans Overclocking

Samsung brought up the rear in our tests. Overclocking is out of the question in principle - this RAM barely broke the 800 mark in our overclocking tests (it posted a speed of 812 or 406 MHz). In standard mode, these modules amble along only in the relatively slow CL4.0 mode. But the vendor's target market is clear and unmistakable: Their modules are built for the OEM sector, and leave enthusiasts out of the picture.
