Forget about the $650 liquid-cooled 1.15 GHz memory you may have just ordered for your rig. Turns out that the OCZ PC2-9200 FlexXLC devices aren't cutting edge anymore, just two weeks after their announcement. Bragging rights for the memory with the highest clock speed are moving over to Kingston's HyperX PC9600 modules, which are clocked at 1.2 GHz. The company also offers a PC-9200 version (1.15 GHz).
A 2 GB kit (2 x 1 GB) is offered at $525 MSRP. Initial 1 GB devices go for $263 and 512 MB versions $139. The 9200 models are marginally cheaper at $518, $259 and $137, respectively.
