OCZ’s PC2-9200 Flex II 4GB kit put to the test
High capacity 4GB kits on higher density chips are still relatively new to the market. The chips used for these products are likely to play catch-up in overclocking, since 2GB kits have been around for a long time and some have ample overclocking headroom.
Keeping in mind that 4GB performance kits are only starting to emerge, the OCZ DDR2 PC2-9200 Flex II 4GB kit offers excellent out of the box performance at 1150MHz, and yet still has headroom to clear 1200MHz and reach a maximum frequency of 1236MHz. That said, not many 2GB kits are able to clear 1200MHz comfortably either.
If you’re interested in high freqency and low latency, 2GB kits are still the way to go. It would take some time before 4GB kits can have comparable overclocking traits of their 2GB brothers. However, if you’re not looking for waist-compressing tight latencies, the OCZ Flex II 4GB kit might just be the one for you. It has capacity (all 4GB of it), and it has the speed (1236MHz) to boot. Even if you were to use the factory spec-ed Vdimm of 2.10V, you can still clear 1200MHz, something that few 4GB kits can do.
