We've replaced the Crucial PC2700 with Corsair TWINX PC3200, and redid the overclocking. As a result, we were able to improve our sycronous overclocking results to 12.5x190, which may not seem like much, but the memory timings are 5-2-2-2, which should result in much better overall system performance. By moving to a CAS latency of 2.5, our syncronous overclocked result was 12.5x192.
