The memory timings used are also important for this test :

Memory ClockTimings
266 MHzT-RAS : 5T-RCD : 2T-RP : 2CAS Latency : 2.0
333 MHzT-RAS : 5T-RCD : 2T-RP : 2CAS Latency : 2.0 (Buffalo Tech only 2.5)
400 MHzT-RAS : 6T-RCD : 3 (2 only possible with Corsair memory)T-RP : 3 (2 only possible with Corsair memory) CAS Latency : 2.0 (only possible with Corsair memory)
444 MHzT-RAS : 7At 444 MHz, the Corsair module can also handle an RAS timing of six clock cycles. In practice, this does not run stably and very little gain in performance can be expected, therefore we measured with seven clock cycles.T-RCD : 3T-RP : 3CAS Latency : 2.5
