[hardspell] Core 2 Duo will upgrade to E0 stepping

post #1 of 25

After 45nm Xeon DP core quad CPU upgraded to E0 stepping, Intel currently announced that two of the 45nm desktop Core 2 Duo CPU and one dual core Xeon CPU will also upgrade to E0 stepping. They are Core 2 Duo E8400/E8500 and Xeon E3110. New stepping CPUID will be changed to 0x1067A from 0x10676 and the changes mainly on power consumption, including:


Support PSI
Support PECI
Support XSAVE/XRSTOR
Support ACNT2 functions


The new ACNT2 functions do not need to refresh BIOS to realize. Their S-Spec will change to E8400 SLB9J, E8500 SLB9K and E3110, SLB9C.


They will ship out at the end of next month.

Nice find! Hopefully i'll get the first batch of these with my new build!

Any news on increased overclocking potential? Or is it all compatibility?

I hope this fixes the DTS issues of the C0 steppings.

is there an increase in perfomance/overclocking with the new stepping?

Typically a new stepping is mostly improvement in the manufacturing process making it cheaper and the silicon slightly better (I.E. lower operating temperatures). Sometime they include a small amount of instructional improvement or errata fixes (which seems to be the case). It is unlikely you will see any performance increase.

Probably not. My guess is that it is just the mentioned features and fix any newly discovered errata.
