What CPU can I put in my Dell C600 laptop

I was given a Dell C600 with a p3 750(ewww) that I'd like to swap the CPU for something faster, I'm pretty sure its a socket 478 so I'm hoping I can go like 1.5 - 2.0 gHz centrino which I've seen going for cheap on ebay. I know I should open it up first and get some numbers off the mobo, but I also know how much knowledge is stored in this forum and I have no place I can really leave it taken apart, so does anyone know what I can put in that baby? There are no mobo or chipset numbers in the bios, the only identifying info in the bios is version A22, Phoenix 1985-1988 and Dell 1990-2002.

  1. Off the top of my head PIII 1GHz processor for sure, but judging from THIS post on the subject . it looks like there is 2 revisions of the motherboard which may make it so it can take an 800 MHz or 1 GHz Pentium 3 CPU only.

    Might be best to sell it on Ebay and get one of the many $499 notebooks that are out at BestBuy or even DELL with coupons right now.


  2. Dell told me it can take a 1 ghz but only cause thats all they tested and it could probably take a lot more. I'm pretty sure I saw a post in this forum which I can't find now that said 2ghz centrino. Maybe I'll try to find out what chipset is in there.
  3. It would be awesome if it could, but that's quite a jump, since even the 610's still took PIII's. It wasn't until the 640's that the processors the size you are talking about got implemented.

    I would check the chipset they used in each system and see if it is compatible with the Pentium 4-M. You can find Pentium 4-M's on Ebay for dirt. I found a 1.8 GHz for $48 shipped BuyItNow.
  4. DOH! wtf am I talking abouit, celeron, not centrino lol. I saw a 2 ghz celeron the other day for 50 buckis or so I think.
  5. Also consider that that system has a 133Mhz fsb, and the processors we are talking about are 400 Mhz. I know that in most cases the chip will automatically clock down, but we are starting to rack up a lot of reasons this will probably not work.

  6. are you sure it's a skt478, usually p3 its socket 370 not 478 so if it's not 478 you can't upgrado to nothing unless its socket 370
  7. Yes, it is Package Type: 478 pin PPGA

    CPU question on DELL support forum.

    The C600/Inspiron 4000 has three different mainboards - one cuts off at 750, the other at 850, and the last can go to 1 GHz.

    Looks like a few people have put Linux on these machines, you might want to check out Linspire, looks like XP and is pretty easy. Mandrake is supposedly the easiest. There is even a guy putting OSX on his HERE which might get you some major "novelty" points.

    All in all I would say that after researching this a little upgrading is pretty much out of the question. There are many people that give up frustrated posting on the internet. If the MAX you can get is P3 1 GHz, it might just be better to sell it on Ebay to some DELL nut for $200, add the money you were going to use to upgrade (maybe another $100) and then sell some plasma or something and get a new computer for $499 at BestBuy or Dell.
