Very good results, but a motherboard with enough VDIMM is required.
Reduced latencies did not give much overclocking headroom. This shows, that this memory is designed for low latencies. Faster than DDR500 with tight timings is very fast, compared to 2.5-3-3-7. In the factory, the SPD Timings were set to the correct values of 2-2-2-5 (we changed Tras to 7).


SuperPi - 252MHz @ 2-2-2-7 - 2520MHz

Benchmarks



For easier comparison with other modules, we set a maximum voltage of 3.1V und 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:


Conclusion

  • Two 512 MB modules are sold for $160 to $200, which results in a very good price/performance ratio.
  • Tight latencies
  • Very good performance
  • Nice design, beautiful heatspreaders
  • Great overclockability
  • Wants lot of voltage
  • Overclocking not increased with reduced latencies
9.1The TwinMOS Twister BH-5 are THE performance memory. Great latencies at speeds of over DDR500, where other memories barely run 2.5-3-3-7, together with a great price, help the memory get our Editor's Choice Award. 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.
