Core 2 duo a 64 bit processor?
-
Hi there, I just bought a dell xps m1710 laptop with the core 2 duo T2600 cpu inside. I just tried to install xp professional 64 bit but I can't as I get a message saying my system doesn't support it. Is core 2 duo not 64 bit? Also will I only ever be able to run Vista x86 not Vista x64 (now available on MSDN). Also does anyone know if there would be any difference if I had the core 2 duo with the Merom core T7400 rather than my Yonah T2600 both at 2.16GHz in terms of installing a 64bit OS. I accidentally bought the wrong model and am regretting the 2mb cache core rather than the 4mb L2 cache on the T7400 anyone know just how much difference this really makes? Am a .Net developer by trade so if it makes a big difference on compile or execute with VS 2005 that would be meaningful. Thanks.

No, it is not 64 bit. Funnily enough I also assumed that it was 64 bit when I ordered two machines at work. You can actually run it under 64 bit emulation mode, probably you will find the appropriate switch in BIOS settings.
Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it. -Brian Kernighan

Just checked my brothers computer and his Core 2 Duo 2.13GHz has 64-bit extensions, so you should be able to run a x64 operating system on it, if it has these extensions.

Yonah T2600 is Core Duo, that's based on Pentium M, and it doesn't support 64-bit. Merom is the new Core 2 Duo, it's based on the new intel Core microarchitecture, and it supports 64-bit. If you have Yonah, you can't install 64-bit OS, you need Merom.

They are a huge difference, much more than just the size of cache. Return it if you can, and get the new Core 2 Duo.

Mine is 2.16GHz also is his a laptop, is it the T2600 chip? What do you mean by "has extentions" are there different version of the chip that you have to buy or is this something you must change in the bios?
He has a desktop model Core 2 Duo E6400, that model has EMT64, which are extensions of the address bus and the addition of 64-bit instructions to the processor core. Don't know about the T6200, but that one is different, because it's a mobile processor. Don't know if they added EMT64 to those also.
