Is it OK to install an Intel® - Core™2 Duo E7500 Processor E7500 into a Dell XPS 410? It has a socket LGA 775 and 1066 MHz bus.

Edit (from comment): I currently have an Intel Core 2 4300 installed in my Dell XPS 410. If I install an Intel® - Core™2 Duo E7500 Processor E7500 will it be supported? The upgrade will cost me $125; is this even a worth while investment?

It MIGHT work, but it will be unsupported.

Generally, for a board to support 45nm Penryn CPUs, it has to have BIOS support. Many things are possible.

-it just won't work -it will work at 65nm Conroe voltages (could be bad) -it will work and just not say the CPU name -it will work perfectly (asssuming Dell has a BIOS for it)

I believe this is a 1333fsb CPU...if you put it into a board with a 1066FSB only, it will operate at a lower speed.

I would seek out a Core 2 6xxx series. If you already have one of those, this upgrade is a big waste of cash.

"I believe this is a 1333fsb CPU". no, it's a 1066fsb CPU: processorfinder.intel.com/details.aspx?sSpec=SLB9Z –  Molly7244 Jan 16 '10 at 18:35

No, the E7500 (Wolfdale) is a 45 nm CPU. They're not supported in the XPS 410.

Edit: an intensive search with various search engines did not yield any proof for a successful transplant of a E7500 (or any other 45 nm CPU for that matter) into an XPS 410.

Ok, one of you will have to specify a source, so we can know who's right :) –  Gnoupi Jan 16 '10 at 14:54
    
ever so vigilant, Gnoupi! :) the same question has been asked and answered in Dell's technical support forum. of course, if John T. has access to more reliable sources (not some SWAG :), unbeknownst to me, i will gladly delete my post to avoid any confusion here. –  Molly7244 Jan 16 '10 at 16:30
    
Different nanometer ratings don't directly break compatibility. You can use a 45nm core2duo or 65nm core2duo in motherboards with core2duo support. They are the same socket. –  John T Jan 16 '10 at 22:44
    
Nowhere on that page does it say those are the CPUs supported by the latest BIOS. He could have copied and pasted it from here: techspot.com/vb/topic94207.html . The latest BIOS is also DXP061-020503, not DXP061-020501. –  John T Jan 16 '10 at 22:57
    
you see ANY 45nm processor in this list? no ... and a recommendation to spend $125 (US, that is) based on assumption is quite irresponsible. post some proof that this particular CPU is supported in this particular computer and i will stand corrected. until then, my No stands fast. –  Molly7244 Jan 16 '10 at 23:45

If you have a decent CPU then you have a 775 socket, but you need the drivers and the BIOS updates for it to work. If you don't need to upgrade your CPU you should not. It is a lot of work. You are better off to upgrade other parts of your PC, like more memory.

Socket compatibility != actual compatibility. –  MDMarra Jan 28 '10 at 14:52
