Intel changes stepping of 800 MHz FSB Xeon
Intel changed stepping of Xeon processors with 800 MHz FSB from D-0 to E-0. Changes are made to 2.8/3.0/3.3/3.4/3.6 GHz models and imply the following:
- New 0F41h CPUID (instead of older 0F34h)
- Energy consumption and performance optimizations:
- Enabled NB (Execution Disable) bit
- Thermomonitor 2(TM2) thermal sensor
- Extended Halt state
E-0 stepping is pin-compatible with D-0. No BIOS or other updates are required.
