Optiplex 755 MT, modded E5450 CPU?

Jump to solution

Is it true that this processor will work in socket type LGA775, an Optiplex 755?  Please see screengrabs.  I couldn't copy & paste.

@JOcean,

There is no reference in that post to a modified E5450, modified for fit.  I already know that a Q9650 will fit.  Issue is price range.  I don't have the budget for a newer computer either.  But figured a quad would take care of a couple of slow issues.  Also, an Intel Core 2 Quad 2.5GHz is faster than a 3.0GHz Intel Core 2 Duo, isn't it?

Speedstep's berating post was not a good memory.  It should've been deleted along with the whole thread.  It also referenced a QX9650, which I did not reference.

My apologies...I saw the 9650 reference and assumed that it was a similar request...my bad. Another instance of my jumping to conclusions...I have sprained many a virtual ankle doing just that in my career.

Thanks.  Wasn't expecting an apology, so that was nice of you.  I've concluded too quick on a couple of occasions myself.  Best for me not to stay up too late doing this. >

You are correct, the Quad is faster because of the cores and architecture. For example the Core 2 Quad Q6600 2.4 GHz has 24% better performance than the Core 2 Duo E8400 3.0 GHz.

This site lends a bit more information and is a great source for comparing GPUs and CPUs.

As far as working on your motherboard, according to the following chart it would appear the answer is no to a modded CPU.

Hey @bradthetechnut,

Found this thread regarding a successful case of modded Xeon E5450 install on a motherboard with the Socket 775. This guy even overclock it to 3.6Ghz! Fast enough, right? I believe it should be ok that CPU upgrade for an Optiplex 755 MT in this way.

Another thread here shows an Optiplex 755 user replace CPU with a X3363, and rated faster than both the Core 2 Quad Q9650 and the Xeon E5450. Worth to read.

Thanks to you too for the info!

With modded CPU's being sold on eBay, I wanted to check with Dell Community first.

I changed the original subject line for other readers.
