The memory timings used are also important for this test :

Memory Clock Timings
266 MHz T-RAS : 5T-RCD : 2T-RP : 2CAS Latency : 2.0
333 MHz T-RAS : 5T-RCD : 2T-RP : 2CAS Latency : 2.0 (Buffalo Tech only 2.5)
400 MHz T-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 MHz T-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
