OCZ did an excellent job on the PC2-9200, it ran at up to 1250MHz without even water cooling! These are simply insane speeds that far exceed any spec that you would have believed even half a year ago. The natural comparison of the Flex XLC would be Corsair's high performance Dominator series. If OCZ was going for a "bigger is better" approach, then they certainly came out on top. The giant OCZ XLC heatspreaders "out-dominate" the Corsair Dominator's impressive looks, and the PC2-9200 out-overclock the XMS2's too.
