It has 1 MB cache size, package type = LGA 775, processor number = 524 Features: (as shown in the dropdown combo box when cpu speed =3.06, processor number = 524) http://processorfinder.intel.com/List.aspx?ProcFam=483&sSpec=&OrdCode= Enhanced Halt State (CIE) Enhanced Intel Speedstep Technology Execute Disable Bit Hyper-Threading Technology Intel EM64T Intel Thermal Monitor 2 Intel Virtualization Technology I wonder if I could benefit from these features when running AMD64 version. On i386 install, I just enabled SMP and the OS happilly reported 2 logical cpus, however, I'm not sure how I will build a particular application to benefit from this hyperthreading thing. There are certain knobs when configuring a particular application that says --enable-pthreads. Does it have something to do with this HT thing? Is it a bad idea to always "pkg_add" rather than "make install"?? Also, I'm concerned with EM64T. Let's say I installed the AMD64 version, those software I will be building via ports will pick up this EM64T thing, right?? No additional knobs? So they run faster? AMD64 is on tier 1 right? Are there any caveats? Will my mplayer, xawtv, and snd_hda patch work flawlessly just like it use to in i386? Howabout this hardware based Virtualization? 'You got any experience on making this work? I mean, running completely different operating system at once, like that of Xen, Virtuozzo, VMware etc. I will consult Intel's docs soon, in the meantime, any idea what are these? Enhanced Halt State (CIE) - Is this supported? Enhanced Intel Speedstep Technology - I think this has something to do with overclocking.. still need to check on their site. Execute Disable Bit - According to the wiki, it has something to do with countering buffer overflow attacks right? is this supported? Intel Thermal Monitor 2 - still have to check if mbmon will work on this one. That's all folks. Thanks! -mark
