- The Modules


OCZ modules are well known in the overclocking community. Their module is one of the highest quality and overclockable modules currently available. OCZ ships the modules in a Dual Channel style kit package. This kit has undergone testings to ensure these modules work perfectly together and at their rated speed on Intel I875 and I865 motherboards. While nForce and nForce2 motherboards are supported, the picky nature of the NF2 does cause some stability errors with the OCZ memory. While the Athlon 64 3200+ doesn't run in Dual Channel mode, it works 100% on the AMD64 platform we had on hand, so no problems on that front.



OCZ uses a copper heat spreader with their initials raised so you will know what modules are in your system. While testing, we found that the heat spreader did get noticeably hotter than the other modules in our tests. In fact, it ran the hottest, however, the units stayed fully stable - it would appear that the copper is able to absorb more heat than the cheaper alloy heat spreaders on the other modules.



OCZ has been known to do a selection of memory modules, depending on who makes the best chips available. The 256MB modules we used were single sided so only one side was populated; a total of 8 Hynix DDR chips have been used. OCZ uses a thermal pad that adheres to the modules for better contact with the TSOP-II chips.


- Overclocking


OCZ have been known for pushing the boundaries of DDR SDRAM, and this kit is no exception.


With a voltage setting of 2.9v (the maximum OCZ rates the modules at) and an unlocked Intel Pentium 4, we were free to push the FSB to the maximum limits that the modules were able to go. OCZ scored a massive 282MHz FSB.
