Test Setup

Performance & Overclocking

The first thing done, when testing meory is simply running it at the rated speed. The ReaperX is meant to manage a very impressive CL4-4-3-12. Such a rating would already be interesting for a 2 GB kit, but we are talking about two 2 GB modules here. OCZ intends for these to run at 2.1V. This is also the setting we benched at out of the box. During our testing we noticed, that the memory easily manages the rated speed at default voltage of 1.8V on the MSI P35. The divider between CPU and memory was kept at 1:1, as the processor can handle at least 500 MHz with a multiplier of 6. The MSI board is also capable of such speed.

We suddenly hit a wall at around 920 MHz for the memory. No amout of voltage at this point seemed to change the result in our favor. Even raising the divider in combination with a lower FSB and looser timings did not yield any better speeds. Seems like our kit won't manage more than this - which is still quite impressive at 4-4-3-12.

Reducing the timings to 3-3-3 also meant reducing the FSB to 333 MHz. There are very few 2 GB kits out there that can manage CL3 at 800 MHz, so that this 4 GB kit can boot and function at 667 MHz is quite impressive. At such tight timings the memory did not manage to get far, no matter how much voltage was applied.

You will usually see CL5 benchmarks as well, but considering the memory clearly won't budge beyond ~920 MHz, which it can do at CL4 already, there is no reason to run any more benchmarks. It does however manage this speed at default voltage, which is good for boards which only offer FSB overclocking.





The voltage scaling graph shows the limit of the memory, which we reach at ~2.1V already. And the fact that the memory does not yield any better results at CL5, this line has been left out. Please note that each individual module overclocks different, the results here can only be seen as an indicator of performance.
