Optiplex dilemma

This question is answered

OK so I had an optiplex 745 who's motherboard fried up. It was a core2duo 1.8Ghz with 2gb ram and an HD 5550. Everything still works except the motherboard. I have decided to just get another optiplex casing with a motherboard and port everything into it. However, I have a choice as to which model I get. I can get either a optiplex 755, an optiplex 330, or another 745. Now I wanted a bit of advice and opinion regarding which of the three (or any other model that you know of that can support my hardware) I should get. I saw a lot of posts around the internet which said the 745s have problems with faulty capacitors, so I was wondering if the motherboard on the 755 or 330 was better than the 745. Personally, I just want one which can be the most durable and can get me atleast a couple of years in.

  • Not all chip sets support going from  130nm to 65nm or 45nm

    Bios should always be updated BEFORE trying a CPU.

  • Hi Stormrail,

    What form factor do you have now?

  • I believe I have the tower currently......

  • The 745 is still a pretty good machine and you still have some upgrades available for either RAM or the CPU. My Dad has one with a quad core processor running XP. So my suggestion would be simply to replace the motherboard and leave it at that. If you're running XP, the bumping the RAM up and going to Windows 7 would give you a nice boost.

    The 755s are slightly better but I'm not sure the effort would pay off.

  • Umm I am finding it a bit hard to get either the 745 or 755 so im considering the 330.....

    What would you say about it?

  • The 330 has a newer chipset and can run a faster FSB speed. But you should check the Intel site for CPU compatibility.

  • The 330 has a Smaller Power Supply and only 2 Ram Slots also I don't think it supports 1333mhz FSB PC2 8500.

    The 755 Tower is MUCH better Due to Better support for Quad Core, 1333mhz FSB and Bigger Power Supply.

  • Yeah I know about the support for core2quad in the 755, but I don't really want to get a core2quad further down the line, because if I have the money, I'll be getting an i3 or i5. I just want this one to get me a couple of years in so that I can save enough to get a completely new PC. I believe the most I am going to do is get an E8400 and 4 gigs of  ram into the optiplex that I get. For which the 330 is more than adequate. Also, the 330 I am having has the same 305W PSU like the 755.

    I found a post here which says that people have been able to put in a Q8400 into the 330. Now like i said i won't be getting a quad core, but since the Q8400 does have a 1333 FSB frequency, I think it's safe to assume that a core2 with 1333 FSB would work wouldn't it?

  • Yes I have already seen the specs, so obviously the 1333 FSB is not supported. What I am trying to say is that people have been able to put the Q8400 into their 330s, which has a 1333 FSB. SO I should be able to put in something like say an E8400 yes?
