Few questions regarding CPU and FSB...

Hey all, I've had a browse around the forum for some answers and although a lot of topics have been helpful, I've not found exactly what I'm looking for. Therefore I decided to start a topic in the hopes that some of you more knowledgable people will be able to provide me with a few answers!

Firstly, I've decided to upgrade my current CPU (Pentium 4 3.00Ghz) to a Core 2 Duo. From various tools I've been able to deduce that my current socket is a Socket 775 LGA, which is compatible with Core 2 Duos.

What I'm unsure about however, is FSB speeds.

This is what CPU-Z shows up on my system currently:



The Core 2 Duos that I've looked at, run with a FSB speed of 800Mhz. Mine seems to be running at 798Mhz. Is this a problem?

Secondly, what's the 90nm that is mentioned?
The specs for the Core 2 Duo I'm looking at have that particular CPU down as 65nm. Is this something I should worry about, or won't it cause a problem?


Ideally, I'd like to just upgrade my BIOS, pop the new CPU in and have it working perfectly without having to do any playing around. Any and all advice is greatly appreciated!

Thanks. :bounce:

  1. The FSB sometimes fluctuates slightly so no problem their. And concerning the NM it stands for nano meter which is a measurement used to measure the core .etc. The smaller the nm the more energy efficient and so on the chip is so that is no problem their ever. I will however encourage you to see what chips are supported by your motherboard befor purchasing also make sure you update your bios to the newest to achieve optimum stability and compatibility .etc
  2. Thanks for the reply.

    I'm glad the FSB and NM measurement shouldn't cause any problems.

    Having run EVEREST and determined that my MB chipset is an Intel Lakeport-G i945G, I had a look at this Wikipedia page:

    http://en.wikipedia.org/wiki/List_of_Intel_chipsets

    From the looks of things there, the 945G doesn't support Core 2 Duos.
    However, taking a look on Intel's website shows differently:

    http://www.intel.com/products/desktop/chipsets/945g/945g-overview.htm

    It states that the 945G chipset supports Core 2 technology. I sincerely hope that's the case, but I would just like to make sure.
    Any advice appreciated!
  3. Compty, it's going to vary from motherboard to motherboard.

    There are motherboards with the 945G chipset that do support Core 2s, and some that don't. You need to make sure that your particular motherboard, not just the chipset, supports the Core 2 chips.

    Can you tell us exactly what motherboard make and model you have?
  4. Hmm well having opened my box up, it seems my motherboard is a Connolly E187242 F2, which a few google searches tells me is a proprietary Dell board. There isn't much information about it unfortunately, so I'm going to assume the worst and say that it doesn't support Core 2's.
    If anyone can tell me any different, I'd be very grateful.


    Now, I don't know much about motherboards but if I was to get a replacement, would something like this suffice?

    Along with the Core 2 Duo I can't really afford a very expensive one. My main concern would be fitting it in my case. As there isn't a lot of information available about my current motherboard, how do I know what size it is?

    Thanks

Wikipedia is a wholly unofficial self proclaimed intenet encyclopedia, endorsed by no one but its users, and editable by anyone, regardless of their credentials, expertise, the accuracy of their information or their intentions. As such, the enrty you read regarding chipset compatability could have been written by Hector Ruiz, chairman of AMDs board of directors.....Intels competition. Conversely, any comments regarding AMD on wikipedia could have been wrtten by Pau Ottelini, CEO of Intel.....AMDs competiton.

    As such, the vercity of any informaytion on wikipedia is always questionable and not to be trusted.

    In short, trust the manufacturers support info, not crapipedias

    You will be an idiot until proven wrong.

    Do you ever scroll to the bottom of Wikipedia entries? Ever notice something called references and bibliography? I really dislike someone bashing something because they are uninformed. Also not anyone can write anything in Wikipedia.

    For example I tested this theory stating that skunks are opportunists and if given the chance will eat fecal material from other lifeforms. This entry was quickly noted and deleted within a couple hours. I may be late in catching your fallible mistake, but that's okay I will forgive you.

    And to stay on topic this board does not support core 2 duo the best you can probably get is a Pentium D which is not necessarily a dual core more logical like the Pentium 4 Hyperthread. But still your best bet for CPU upgrade.
  7. Is this a Dell machine?
    If so what is the model number?
