Optiplex 745 Processor upgrade

Hey Guys,

I have a Dell Optiplex 745 with an E6400 @2.13ghz. I was wandering if it would be possible to install an E8400 @3.0ghz? Would my mother board be able to take this?

Thanks in advance.

I strongly suspect it can.

Both are socket 775 processors and will fit the motherboard.

I'd guess you could go as strong as a quad 6600, but there is always a chance you'd need a BIOS update.

Google tells me that there is a BIOS as late as 2.6.4 from March 2010.

Really, I wouldn't expect a significant difference going from E6400 to E8400, but I don't know what you're paying for it nor what you expect.

Thanks for your fast reply.

I just want slightly better performance in excel and powerpoint mainly. I've found one for 12 used so its not too heavy an investment.

I heard that DELL restrict what processors can be used in an attempt to stop people upgrading their rigs.

OEMs do that. You'll find a lot of OEM machines that can only take one or two different processors, because the BIOS is locked down that way. I had an old HP that would only take one (and only one) model of Athlon X2. Trying to find one to replace the old one when it went south was a real pain.

After a bit of research on google, it appears that there are split opinions on whether it would work or not :/ Would it be possible to overclock my current e6400 to around 3.0ghz? Or is that another way DELL has screwed me over

Most OEM BIOSes don't have the settings to change that would allow you to overclock the rig. You could look, but I doubt that the FSB speed is controllable from BIOS. That would mean OCing is a no go.

The mobo supports up to C2Q Q6700 and 8GB DDR2-800 and no NO overclocking on a dell unless its BSEL and since that board supports up to 1066mhz bus and the C2Q is then your stuck at the 2.4ghz
