Question About Motherboard - CPU Combination - Please
I need to know of a specific combination of a motherboard that WILL NOT support 64-bit mode (AMD64/Intel EM64T ) but will work with a 64-bit CPU (AMD64/Intel EM64T capable). In other words a motherboard model that will take, say an Athlon x64 or Intel Core 2 Duo, where the 64-bit capability will be wasted, but will run well in 32-bit mode. Many thanks. |

What I actually meant is when "the disability" to run 64-bi is not at the OS level only but also at the motherboard level. That is a chipset that will not support the 64-bit capability of a 64-bit CPU but will run well with it in 32-bit mode. And if so what actual motherboard model and CPU could be and example of such setup. Thank you. |

The chipset has nothing to do with it other than providing access to peripheral devices. So you can't disable the cpu's ability to run in 64 bit mode via a chipset. All we're talking about here is the instruction set the cpu uses. That's in the cpu, not in the MB, not in the chipset. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org http://mysettopbox.tv/knoppmyth.html Usenet alt.video.ptv.mythtv My server http://wesnewell.no-ip.com/cpu.php HD Tivo S3 compared http://wesnewell.no-ip.com/mythtivo.htm |

But doesn't the motherboard has to offer 64-bit wide buses in order to work with a 64-bit CPU? See this: "With appropriate 64-bit supporting hardware and software, platforms based on an Intel processor supporting Intel EM64T can enable use of extended virtual and physical memory. Intel EM64T provides flexibility for 32-bit now and future software that supports 64-bit computing." http://www.intel.com/technology/64bi...ions/index.htm The part "64-bit supporting hardware" surely refers to the motherboard. It implies that the 64-bit CPU will work like a 32-bit CPU when such hardware support is missing, and as a 64-bit CPU when it is present. |

Please tell me what the sentence "With appropriate 64-bit ***supporting*** hardware" refers to? It obviously doesn't refer to the CPU, it refers to some other hardware the CPU need in order to operate in 64-bit, that much is clear. What hardware do you think that is? |

Intel EM64T provides flexibility for 32-bit now and future software that supports 64-bit computing. The 64 bit hardware is the MB designed for that CPU. The software is the OS. It can be 64 bit or 32 bit or even 16 bit. Yes, you can run old msdos on it. Do you get it yet? The software you run determines if it's 32 bit, 64 bit, or even 16 bit. This isn't the old days where the cpu bit size was determined by the data bus, or the later days where they started using the register size to define the bit width. This is today, and with marketing practices they way they are today calling a 200MHz bus 400Mhz and even 800MHz in Intels case, what do you expect. But you can forget about the MB doing anything bit wise except interfacing to the CPU. The os(really the particular application) determines what mode you run in. yes it's possible to run a 32bit app under a 64bit OS. It's done in Linux all the time. I couldn't say for windows since I don't run windows. It obviously doesn't refer to the CPU, it refers to some other hardware the CPU need in order to operate in 64-bit, that much is clear.
