Processor Upgrade info Needed for Dell OPTIPLEX(s)

Hello,
I'm looking for the best (maybe also the 2nd best to save money) processor that I can upgrade to for a DELL OPTIPLEX GX745, 745, & 755.
I hate Dells, but this is for my boss who wants to get these to 3.0ghz and isn't listening to me. Any help/links will be much appreciated! also, feel free to email me directly at bsmove2010@gmail.com

Thanks in advance!

  1. I have a 745 and I know that a E4xxx series will work since I replaced my Pentium D 945 3.4ghz with a E4300 1.8ghz which despite clock speed is faster.
    You can use 65nm Core2Duos which are the Allendales and Conroes.
    So a E6xxx series Conroe 65nm should work also.
    A good way to go would be the E6600 65nm Conroe.
    Dont worry about hitting 3ghz since the Core2Duo at 2.4 will beat the Pentium D 3.4 easily.
    The 755 supports higher end C2Ds and C2Quads so I think you can use 45nm Wolfdale duals and also some quads.
    Do a search on Toms search line for optiplex 745/755 upgrades.
    There are plenty of threads regarding cpu upgrades on those machines
    on here.
  2. here is some links
    this one is for figuring out which cpu fastest

    this one is info on Core 2 Duos

    this is 745 user guides

    this one is for 755s
    http://support.dell.com/support/edocs/systems/op755/en/index.htm

    also go on ebay and look up each model and see what came from Dell in those units

    From my research I found that E6600/Q6600 will fit 745s though I havent confirmed that yet :)
    I believe that almost any C2D/C2Q will fit 755s (E8xxx,Q9xxx etc)

    I like my 745 actually even though it is a Dell LOL
    It is quiet, draws low power and was CHEAP buying it used.
    The business class Dells (optiplex,vostro and precisions) usually
    are decent from my experience.
  3. Funny people dont want to use their personal email here but will put personally identifying websites in their profile.
  4. I was just talking in general.
    I have seen in other members info that they include personal sites.
    Not you, Mr. Paranoi LOL
    Though remember "just because your paranoid doesnt mean they are not
    out to get you" :)
  5. Take the blue pill!!!!! ...

    Oh ...
  6. Why Firefox?
    I use IE but I always thought that Firefox was the "hackers choice".
    Safer against viruses supposedly.

    Where is the OP since we are hijacking their thread.
    I put up some good info and links and would like to see what they think...

    Oh ...


    I agree with you
    take the blue pill definitely
    ignorance is bliss
    other people know what is better for me........
  8. ^ Good question!
    Maybe that explains Lady GaGa...

    is that done by exploiting the DNS redirection that Comcast uses to hijack invalid URLs?
  10. I always wondered where that crazy Lady came from ...

  11. Yea I know
    I was thinking about trying Opera.
    I gotta post a thread in applications about it.
    I just reinstalled my OS and I got to build another VM (Virtual Box) to do my browsing/downloading with.
  12. on Vitual Box I just save the state of OS when first installed to external and then if craps out I just restore to prior state.
    I just do it to be on safe side.
    With IE8 and winxp and win7 on host I have had very few cases of viruses.
    in the past 2 years I only got hit with Noobface (freakin' hate Facebook!).
    I use Nortons Security Suite 2010 and manually scan with MalwareBytes.
    Just get hit with alot of tracking cookies LOL
