First benchmarked using latest Passmark:


Then did some tests with latest Aida64:

Memory Read: 2884 MHz - Triple DDR3-1311 - 9-9-9-24 CR1 - 11394 MB/s
Memory Write: 2500 MHz - Triple DDR3-1314 - 9-9-9-24 CR1 - 7739 MB/s
Memory Copy: 2500 MHz - Triple DDR3-1314 - 9-9-9-24 CR1 - 8489 MB/s
Memory Latency: 2900 MHz - Triple DDR3-1312 - 9-9-9-24 CR1 - 77.6 ns

CPU Queen: 2500 MHz - Triple DDR3-1314 - 9-9-9-24 CR1 - 64097
CPU PhotoWorxx: 2500 MHz - Triple DDR3-1314 - 9-9-9-24 - 60555
CPU ZLib: 2733 MHz - Triple DDR3-1300 - 9-9-9-24 - 485.2 MB/s
CPU AES: 2500 MHz - Triple DDR3-1314 - 9-9-9-24 - 659823
CPU Hash: 2733 MHz - Triple DDR3-1305 - 9-9-9-24 - 4347 MB/s
FPU VP8: 2876 MHz - Triple DDR3-1307 - 9-9-9-24 - 3462
FPU Julia: 2633 MHz - Triple DDR3-1314 - 9-9-9-24 - 24904
FPU Mandel: 2880 MHz - Triple DDR3-1309 - 9-9-9-24 - 11963
FPU SinJulia: 2633 MHz - Triple DDR3-1314 - 9-9-9-24 - 10778

What's interesting here is that both processor and memory speed keeps fluctuating.
I have not found a good explanation for this behavior - if you have an idea - let me know at neolisk@gmail.com.
