And another:

CPU vendor : AuthenticAMD
CPU model : AMD Phenom(tm) II X4 955 Processor
CPU stepping : 2
TSC flags : tsc rdtscp constant_tsc nonstop_tsc
Using mfence_rdtsc because you don't have an Intel CPU
Will test the "mfence;rdtsc" clock.
Now test passed : margin 208 with 8769512 samples
Load3 test passed: margin 339 with 4880373 samples
Load test passed : margin 193 with 7189144 samples
Store test passed: margin 192 with 7149930 samples
