core 2 duo with 2mb cache (allendale) is it disabled

[kocoman]

What program can check if your CPU supports eist and VT? I think allendale cores has 2M, EIST and VT removed.
All CPU-Z image captures doesn't show speed step (EIST), and virtualization technology (VT). flags. What program can accurately check it (Bypassing the bios)? Thanks

its something i've been curious about and cant find the answer to.

E6300 and E6400 Allendales are exactly like Conroes except that they have half of the L2 cache disabled. They are exactly the same die; half of the L2 cache is disabled via fusing.

According to this post from the http://techreport.com/forums/viewto...p=588980#588980
(I don't know if he enabled VT in the bios? or linux ignores it?)

Does anyone have a /etc/cpuinfo of a E6600 E6700 or xtreme edition? I find that the flag vmx "Vanderpool/Virtualization Technology" is missing from the 6300 post in the first page. Can anyone confirm? Thanks

They do NOT have half the cache disabled, they are manufactured with 2mb of cache, they do still have VT and EIST.

Ok seriously e6300 is NOT comparable a celeron.

Making CD's, digital photos and even tv viewing with a tv tuner are not even intensive to the CPU.

Without benchmarks, give 5 computers with each conroe/allendale and you won't be able to tell which is faster at making CD's, digital photos and even tv viewing with a tv tuner.

The Conroe is unlike the P4 in that its least powerful part is not crippled to the extent that the Celeron was.

I think an Allendale chip is a very decent performer given all the benchmarks I've read.

Just my opinion, but Celerons were absolute shite. The E6300 on the other hand is not.

Quite glad they haven't severely crippled this chip, yet.

Unless Intel is misleading us, I think this link proves that all of the Conroe/Allendale chips have both VT and EIST:
