Dear Friends

I am in dilemma to understand the concept
am having cellron 2.66 processor gigabyte motherboard.
when am trying to install rhel5 64 bit os it through error it wont
support long addressing.by this we can tell that its wont support 64bit operating.

if i replace cellron 2.66 precessor with dual core processor which 64bit compatible will it work.

32bit and 64 bit differentiate only in processor or also in motherboard architecture.

Thanks & Regards

yes that will work IF your board supports the new cpu. Do your research before buying. Why do you have to have 64 bit? There are performance improvements on most applications, but in my opinion not worth spending the money to upgrade if you don't have to have it...

Is there a 64 bit dual core processor that plugs into the same socket type as your Celeron? (I don't know socket details for Intel CPU's so I don't have a guess whether that is likely).

What about the power draw of the new CPU you are considering? Even if the power supply can handle it, there are capacitors and possibly other components on the motherboard that won't work correctly above some CPU power draw. If the new CPU draws more power than the old one, make sure that is supported.

I have read statements that some motherboard components are not compatible with 64 bit OS's, even on a motherboard that can use a 64 bit CPU for a 32 bit OS. I never found those statements convincing. I never found any supporting details and I generally don't believe them.

I have seen slightly more convincing claims that certain BIOS versions won't support 64 bit OSs. Even that has been lacking details and unconvincing, so my best guess is that it isn't correct. But I am not at all sure.

Are you looking to upgrade ram up to or beyond 4GB as part of the switch (or even the reason for the switch) to 64 bit?

32 bit PAE kernels support 4GB to 12GB about as well as 64 bit kernels do. Your motherboard or BIOS might be limited to three point something GB. In that case, neither a 64 bit kernel nor a 32 bit PAE kernel could support more than that three point something GB.

Dear
bret381, jonsfine thanks for your suggestions i would like to use RHEL 64 bit OS thats why i want to know about that i got the information from you.

Thanks again to you

BTW, why RHEL?

Your question seems to imply a very restricted budget. Otherwise getting a new motherboard would make a lot more sense. Is paying for support from Red Hat the best use of your limited budget?

Maybe it is. I don't know your situation.

But if you either didn't understand that RHEL requires paid support or didn't understand that you have a choice, then you should know that Centos is just like RHEL but free and without paid support (free support available here at LQ).

I have heard about various free trial copies of RHEL. (I don't know specific terms or details).

If you have one of those and your intention is to use the free trial to find out if it works well and upon discovering that pay for support, then that is a sensible use of the free trial.

But if you intend to just use the free trial without paying, without support and without updates. Don't make that mistake. Use Centos instead. Compared to running RHEL with updates, Centos has every benefit of RHEL and has the very big advantage of free updates.
