It’s the cockroach of the CPU world: hard to kill, still running in dusty server rooms, and secretly powering industrial controllers that will outlive us all.
Do you have a Sandy Bridge system still pulling daily duty? Tell me your story in the comments below.
| Erratum | Description | Workaround | |---------|-------------|-------------| | | Under heavy AVX + VT-x load, the machine may hang. | Disable AVX in BIOS or upgrade microcode. | | BDM80 | The RDRAND instruction may return all zeros for first ~100ns after wake from deep sleep. | Ignore first read (mostly patched in Linux kernel 3.16+). | | HSE137 | P-state transitions can cause a 1-2μs jitter in HPET timers. | Use TSC instead of HPET for high-frequency trading. |
grep -E "model|stepping" /proc/cpuinfo | head -3 Look for: model : 42 , stepping : 7
Stepping 7 is rock solid for general use. Only AVX-heavy virtualization required caution. How to Check If You Own One Linux:
