原來如此
感謝
我也查到了關於這個的解答

Major Difference between E6300 Step L2 and B2 :
L2 : SL9TA , CPUIDString 06F2h , Vcore 1.225V-1.325V , Tdiode N/A
B2 : SL9SA , CPUIDString 06F6h , Vcore 0.850V-1.3525V , Tdiode enabled

Important Note*:
1.Allendale-based CPUs won't reach as high frequencies at overclocking as Conroe-based CPUs do.
2.L2 Step is Allendale Core but B2 Step is Conroe Core

還有這個

i had ES allendale E6300 and E6400 a long while ago. They clocked well, not much difference from any other native conroe E6300/E6400

They wernt xtremely good clockers, they are just E4300 w/ a 1066mhz fsb.

E4300 is a better value, higher mult.

remember, a E6300 B2 step was a conroe with only 2MB l2 cache enabled. Now that yields have improved, we have smaller die sizes. this helps lower prices since cache takes up so much wafer space.

想請問Allendale Core是不是被鎖倍頻呢?
從上文看起來好像是
好像Conroe Core的核心才是原生的

----------------------------我是分隔線------------------------------
那SL9TA可調的核心電壓範圍比較小
為什麼要這麼做呢?

SL9SA的電壓範圍在0.850V-1.3525V
電壓降的越低對散熱功耗不是比較有幫助嗎?
能調的電壓範圍越廣是否代表製程較為先進呢?


SL9SA

Core Stepping:B2

Supported Features: Dual Core
Enhanced Halt State (C1E)
Enhanced Intel Speedstep® Technology
Execute Disable Bit 1
Intel® EM64T 2
Intel® Thermal Monitor 2
Intel® Virtualization Technology

Notes:
These parts are PECI enabled.
These parts have Tdiode enabled.
These parts have Extended Halt (C1E) power of 22W.



SL9TA

Core Stepping:L2

Supported Features: Dual Core
Enhanced Halt State (C1E)
Enhanced Intel Speedstep® Technology
Execute Disable Bit 1
Intel® EM64T 2
Intel® Thermal Monitor 2
Intel® Virtualization Technology

Notes:
These parts are PECI enabled.
These parts have Extended Halt (C1E) power of 12W.


兩者之間還有一個差別
就是These parts have Tdiode enabled.
有大大知道這是什麼嗎?Tdiode enabled: Yes
