Very good results, but a motherboard with Vdimm up to 3.1V is required to see the sweet spot of these modules.
Reduced latencies give you a nice gain in overclocking, but not that much, it's better to run these modules with the tightest timings you can get. This shows that this memory is designed for low latencies. Faster than DDR500 with tight timings is very fast compared to 3.0-4-4-8, which is the default specification.
For easier comparison with other modules, we set a maximum voltage of 3.1V and tested until we found the highest clock frequency and fastest timings for this memory. The Benchmarks Everest Read, Everest Write and Quake 3 were run. We then calculated the performance increase in percent compared to some standard DDR400 memory running at JEDEC DDR400A (2.5-3-3-8). The average percentage of the three benchmarks is listed in following table:
|9.2||The Crucial Ballistix Tracer are really great performance memory modules. Great latencies at speeds of over DDR500, where other memory barely run 2.5-3-3-7, together with a great price, help the memory get our Editor's Choice Award. The only drawback is that you need a motherboard which can supply a high memory voltage, which not all boards offer. But there are voltmods for most of them.|
