In addition to introducing a few new models, Q3 will see Intel updating its dual-core processor line-up with the move to the E-0 stepping. The 'victims' of the stepping change will be the Xeon 3110, Core 2 Duo E8400 and E8500. The E-0's changes include:

- New SSpec and MM numbers
- CPUID will change from 0x10676 to 0x1067A
- Power Status Indicator (PSI) is supported
- PECI implementation change
- New instructions added - XSAVE/XRSTOR
- New ISA extension for save/restoring context of x87, SSE, and future processor state
- New feature added - ACNT2
- Improved mechanism for determining processor utilization. To be used for more efficient P-state determination.
- Package change to Halide free package

The E-0 processors will not require any BIOS updates but, in able to use the Power state Indicator (PSI) the board will need new circuits.

Novas boards? tá bem..
Isto agora para utlizar todas as features tem que se trocar de placa mãe. Já parece os phenom com o AM2, mas ai até era um socket mais avançado.. ( AM2+)
 
sao novas revisoes dos stepings do E8400 e E8500 (passa para steping E-0) nao sao necessárias boards novas , nem seker é necessário um simples update á bios

Intel Core 2 Duo E8400/E8500 and Xeon E3110 Moving to E-0 Stepping Next Month

After moving all 45nm Xeon DP quad core processors from the C-O to the E-0 stepping, Intel announced today that three more 45nm processors will also be upgraded to E-0. The two desktop Core 2 Duo E8400 and E8500 plus the server Xeon E3110 CPUs will all be updated to the E-0 stepping next month. Changes that will come with the E-0 stepping include:

  • - CPUID will change from 0x10676 to 0x1067A
    - Power Status Indicator (PSI) is supported
    - PECI implementation change
    - New instructions added - XSAVE/XRSTOR
    - New ISA extension for save/restoring context of x87, SSE, and future processor state
    - New feature added - ACNT2
    - Improved mechanism for determining processor utilization. To be used for more efficient P-state determination.
    - Package change to Halide free package
The E-0 processors will not require any BIOS updates. They'll be easily recognisable by the new sSpec numbers: SLB9J for E8400, SLB9K for E8500 and SLB9C for E3110.

Se aquecerem menos e fizerem Ainda mais OC do que o steping actual já era excelente , depois ter ou não ter PSI (Power state Indicator ) no meu caso e secundario :D

X2 é mais uma opção para desligar na bios para não "atrapalhar" no OC :002:

X3... É uma feature complicada, pois quem sabe para que serve e como tirar partido dela, não a utiliza por causa do OC e quem podia tirar partido dela, a maior parte das vezes nem sabe que existe ou como a utilizar.
E andam a ASUS e a Gigabyte às turras por causa disto! :p
