Here's one:

CPU vendor : AuthenticAMD
CPU model : Quad-Core AMD Opteron(tm) Processor 8356
CPU stepping : 3
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 252 with 7198256 samples
Load3 test passed: margin 536 with 1833844 samples
Load test passed : margin 219 with 3097882 samples
Store test passed: margin 250 with 3553454 samples
