Intel Core Duo datasheets - for REAL propellerheads !!!

I don't even pretend to understand much more than the page numbers

But I did notice, on page 7, that VT (intel virtualization) is on the spec list.

it's also an option in the bios of my 9400

I tougth Vt was out of the question fore core duo, as were ht, and emt64

The rumor is that Yohan really is Merom, but some functionality (like 64-bit) has been disabled. Apparently, they decided to leave VT enabled.

yea I am kinda frustrated by that why? why? why? 3rd generation centrino is not 64bit enabled, virtualization huh...

i would love it to have the 64 bit extension

For what i heard emt64 is just a 64 bit adaptation but is a real 32 instruction set, what i understand is that it allows 64 bit addresing by merging two 32 bit addresses

Yeah, EM64T is mostly worthless on a laptop. Unless you think you need more than 4GB.

naah that is not what i want! I wanted it to have to be able to play FarCry in 64bit version, or maybe like running XP 64bit edition

I also believe that they will start making 64bit Games, which would differ from their 32bit versions in performance/graphics

but of course 64bit computer arhitecture wasn't build gaming in mind....but surely it can benefit from it, and it will

Hmm, I can't get to it for some reason. Can anyone tell me what it says about the operating temperatures for the T2500?

d@mn - I'm trying to find the doc - I'm derned sure I saved it... I'll get back asap...

ok - got it now. It did open from the link (took a while though).

I'm not 100% what the different values are detailing. On page 70 (table 6.1) they refer to a note that says "at 100 degrees celcius". A further comment says: "The TDP specification should be used to design the processor thermal solution. The TDP is not the maximum theoretical power the processor can generate."

Sorry I can't give more details. The PDF is 2.9MB - I could try and email is to someone ...?

at 100c is just refrence to what the operating peramaters would be like at 100c... for instance the current gain of a transistor increases with temperature and so does bakward leakage current(which is bad) which doubles every 10c... or at least that was what it did on the prescott... they usually use room temp or some other temp as a refrence point as the values would be different at different temps

and yes since the beginning of time processors have been consuming slightly more power than what they say... I can't remember exactly but not 100% of the cpu's power consumption is transformed into heat enegery thus the actuall wattage is slightly higher than the TDP... it's not really that much more as heat dominates most of the power usage...

there's only 3 bsel pins on the cpu... so in otherwords 400,533,667... that's it... no 800mhz fsb so pinmodding will be impossible even on 800mhz desktop systems!!!!

but they did add some more vid pins... voltages now go from NEAR 0 to over 2v... can you imagine running your chip at NEAR 0 voltage... well other than the part about the chip not being stable AT ALL... it seems interisting... i'm still waiting on nhc to update so I can see just how low the chip can go...

and I thought the VT was disabled on all but the fastest processor... I guess it's worth another looksee... also I diden't see anything about 64bit but half that document is hard to read... I can understand it partially cause I like to read whitepapers...

also intel increased the maximum temp before emergency shutdown from 93c to 126c... I'm not exactly sure why if the chip supposidly runs so cool...

Thanks for the info ozzo. Does that mean that anything up to 70* or so would be considered a safe/acceptable operating temp for the Duos?
post #14 of 15
Nice info. Has anyone heard if the Core Duo has PAE (Physical Address Extension)? I would assume that it does since Mac OS 10.4.3 requires it and the Mac-Intels use the Core Duo, but I haven't been able to find it in any documentation.

70c I guess is ok but it should be a little lower than that...

and maybe apple changed some stuff... I think bolth sides gave in a little bit to make it work...
