Re: Dell Dimension 8400 CPU upgrade

Those processors support both 64/32 bit systems? Good to know.  I have a few questions if you don't mind my asking.

Is the motherboard limited to 32 bit?  I was always told I couldn't upgrade the processor to 64 bit because the motherboard wouldn't support that.  It'd be great if I could, I happen to love my old 8400.  

@JIMPYS  My second question is about Window 7 & running it in the 8400--how is it working for you?  From the Win 7 adviser I wasn't certain if it would be worth it to upgrade.  Are you happy with the performance and able to use most of it's features?  The adviser said that due to the MB I would have problems with "AERO" and "XP" mode  so it would be really good to hear about it from someone with a Dimension 8400 that is running that OS.

Basically I'd like to do what munro284 was asking about--try the fastest cpu I can get for this computer.  It already has max ram, higher watt PSU & graphics card added over the years so there are a few odd years of life to it yet..   I am at BIOS A09 {and what ever the last upgrade to that was} so I should be good.  I'm curious where you have found the 670 CPUS because the only processor I have been able to find was the one I already have {P4 3.4ghz which is a 550 I think}.

@ shesagordieyou have the 660 installed did it cause your fan to run louder like Munro284?   672 might make the fan run louder?  or does it just need a different fan?  Just wondering if the fan running louder is a symptom of something else.  Thanks in advance :).
