OCZ has outdone themselves with the PC2-9200 Flex II 4GB kit. From a great retail presentation to an excellent accessory selection, to great cooling and performance. While the issue of the sheer size of these modules heatspreaders is of concern due to blocking the remaining memory sockets on most if not all motherboard layouts, it should only be a serious problem for those users with a motherboard layout that places the dual channel memory sockets directly next to each other rather than staggered.
While the kit can indeed run over 1100 MHz at CL5 with just 1.8V and over 1200 MHz with 2.4V, this also seems to show that the kit has been binned nearly to its limit with just 61MHz of overclocking headroom.
