DDR2-667 Test Mode
Now we will see how the DDR2 SDRAM modules behave at 667MHz frequency. OCZ PC2 4200 Enhanced Bandwidth Platinum memory couldn?t work at this frequency with its default timings, so we had to manually select 5-5-5-12 timings for it.
Synthetic tests come first:
| Corsair CM2X512-5300C4PRO | GEIL PC2-5300 | OCZ PC2 4200 EB Platinum | OCZ PC2 4300 | PQI25400 |
ScienceMark 2.0 |
Memory Bandwidth, MB/s | 5470 | 5432 | 5415 | 5349 | 5413 |
Memory Latency, cycles | 283 | 293 | 294 | 294 | 293 |
Memory Latency, ns | 80.75 | 83.6 | 83.89 | 83.89 | 83.6 |
SiSoft Sandra 2005 |
RAM Int Buffered Bandwidth, MB/s | 6009 | 5992 | 6036 | 5859 | 5994 |
RAM Float Buffered Bandwidth, MB/s | 5992 | 6006 | 6020 | 5854 | 5998 |
RAM Int Unbuffered Bandwidth, MB/s | 5196 | 5103 | 5109 | 4650 | 5102 |
RAM Float Unbuffered Bandwidth, MB/s | 5195 | 5108 | 5105 | 4651 | 5104 |
The Corsair CM2X512-5300C4PRO memory seems to be overall the best in this test, although the OCZ PC2 4200 Enhanced Bandwidth Platinum has the best result in the memory bandwidth test of SiSoft Sandra 2005 with enabled memory prefetch and buffering.
And here are the results in real applications:
Corsair?s CM2X512-5300C4PRO modules provide the highest performance at 667MHz frequency. The sticks from GeIL and PQI have good results against the competitors, too.
