  1. Hi everyone:

    I was wanting to upgrade my processor from a celeron 2.60 GHz to a 2.8 GHz intel P4 or a dual core AMD processor. I heard that a celeron wasn't the bet for games, so that's why I wanted to upgrade. Here are my specs:

    eMachines T2682
    Intel 845GV motherboard
    PNY Verto GeForce FX5500 128 MB ddr dual vga PCI
    Intel Celeron 2.60 GHz
    Western digital 80 GB HDD
    768 MB RAM
    Windows XP home edition SP1
    3 cooling fans, 1 mobo, 1 processor, 1 graphics card.

    First of all, how do I put in the new processor without frying my computer, and secondly, how do I install the drivers without making my PC go permanently blank? Thanks for help in adavance.

    U would need a new mobo first of all for an AMD processor or even a dual-core Intel.
    As for ur processor question, why not buy it from a store near ur place and give ur PC to them to let them install the stuff? I would do that unless what I wanted wasn't available there. For drivers, go into safe mode and uninstall the old drivers. Then boot up XP normally and install the new ones. Also, I would recommend that u upgrade to SP2.

    well the reinstalling bit is easy.. if it doesn't boot, then pop in your winXp cd and Repair windows... and then you can proceed installing the relevant drivers..

    If you plan to keep your mobo, then you'll need to find a P4/AMD chip that has the same socket type and is compatible to that mobo.. unfortunatly i'm no expert at mobo/cpu combos so i'll leave the floor open...

    You have given us the name your motherboard's chipset, but not the motherboard's model number.

    Is your board the D845GVSR or the D845GVFN?

    I just checked, and they both have pretty much the same CPU support list. Looks like the Pentium4 2.80A GHz 533 MHz 1 MB L2 cache model is your best bet. As for how to install it, here is a well written "how to" guide for you:

    celerons aren't good for anything, not just games. they're budget processors for web browsing or word processing, etc.

    what's your upgrade budget?

    depending on what you were planning to spend on a P4, you may be better off with a a CPU/mobo upgrade, not just the processor alone. you're still on a socket-478 platform which doesn't leave much breathing room for upgrades. like rage mentioned earlier, you will need a new mobo for a dual core anything whether it's intel or AMD.

    Today I'll talk to eMachines because they can tell me of a compatible processor that I would like. Also,I have no WinXP cd, so I'll just borrow one from a friend.(I fixed a virus problem on his comp, he has a Winxp cd). Also, I was thinking of a budget of about $100-$150. I dont care about upgrading speed or if I want it dual-core or whatever. I can go with a Intel P4 2.60 GHz or an AMD Athlon 64 2.60 GHz. Also, Mobo upgrade is impossible for me. It's just too much trouble. Do you guys think an Intel P4 with HTT 2.60 GHz will work with my current motherboard? Thanks for all the replies guys :)

    well if a motherboard upgrade is "out of the question", then it would be impossible to upgrade to anything but a socket-478 P4. (if you browse through this forum you will find out that defective motherboards are a very common problem on emachines, so you may have to replace it sooner than you think ;))

    you can buy a socket-478 prescott at around 2.6. it won't support hyper-threading, but that's no big deal. in most cases hyperthreading does not significantly improve performance, and sometimes it can even decrease performance. either way, it cannot compare to a real dual core CPU.

    an athlon64 (socket-939 or AM2) is better than anything you can upgrade to on that motherboard. an athlon64 at 2.6GHz would run circles around a P4 at 2.6GHz, clock speed alone is not an acurate measure of processor performance.

    also, I have to correct an earlier statement I made...
    Rage and I were both wrong, it appears that you can indeed buy dual-core CPUs for socket-478, here is an example

    I doubt your motherboard supports prescott core cpus, so look to be sure you're getting a northwood p4.
    I don't think a core duo will work on a desktop 478 board, but I could be wrong.
  9. KingCody

    KingCody TS Evangelist Posts: 992   +8

    when I found those CPUs online, I also remember reading that some desktop motheboards could use them, but i didn't save the link.

    either way I'm sure the emachines board won't work with it, i was just saying that socket 478 dual core processors do exist.

    so essentially we were not wong, because he would need a new board, but not because if the socket type.

    thanks for clarifying that up :)

    if you can help it- avoid emachines. They're of extremely poor quality. We have had many, many complaints here on techspot regarding emachines.

    I spoke to eMachines and they said that a compatible processor would be a Socket 478 and has an FSB speed of 400 MHz. Can you guys give me recommendations? I need a good AMD dual-core or an Intel p4. Thanks guys!

    Those mobile CPUs aren´t electrically compatible with most of the socket 478 mobos. The 845GV chipset doesn´t support them.

    Regarding the CPU, I highly doubt that your mobo supports prescott CPU´s.
    You have to look out for Northwood CPU´s.

    If you can, give us your mobo model, and how much can you spend, and we´ll help you.

    Good luck!

    I'd stick with the old standard P4-2.4 Northwood core, 400mhz FSB. It's a decent CPU and will be a bit quicker than your current Celeron:

    You also need to buy some thermal compound for re-attaching the fan/heatsink. Be sure to get Artic Silver 5 for this for best results. You should also consider a new fan/heatsink as the stock Celeron one may not provide adequate cooling. You should be able to get the fan + a tube of artic silver for under $40 USD at NewEgg for top of the line.. $15-$25 USD for budget.

    If you're planning on going AMD, plan on replacing the entire PC.. which is still doable if you have the budget. Figure on about $550-$700 USD if you have that much to spend.

    KingCody TS Evangelist Posts: 992   +8

    he would not have to replace the entire PC, he would just need a new mobo. (and maybe a better PSU). that cost would much less than $550-$700, more like $100 and above.

    but if you read the above posts you would know that he is not willing to upgrade the mobo, so something in the socket-478 lineup is all he can upgrade to.

    sw123, i have noticed you keep mentioning AMD. You have to understand that you have an intel motherboard that takes only Pentium 4 cpu's. You cannot put an AMD cpu in an intel socket 478 motherboard. You would have to buy a new motherboard to use an AMD cpu.

    As already stated you need a P4 2.6 socket 478 Northwood with FSB at 400. If i recall correctly they also have the P4 socket 478 northwood at FSB 533 or some other FSB, so make sure you get the one with FSB of 400 only.
    But as also mentioned the heatsink\fan you have on the celeron likely wont be good enough for the P4 2.6 cpu, so you will have to get a new heatsink\fan and some thermal paste along with your new Intel P4 2.6 FSB 400 cpu.

    I suggest you get a friend to help you with this.

    Thanks Nork...I could really use that CPU. Just tell me how to install it without frying the computer!(like if you align the pins wrong)

    I researched a little and found out that the mobo can take Prescott CPUs as well. So what would be the best processor for his PC that would be a great balance between speed and price. He games on it quite occasionally and we've just got a 6800GS for this PC to replace his 9200SE. Thanks in advance.

    P.S. - Intel only guys. He doesn't want to get AMD for some reason so we're stuck with Intel here.

    sw123, sorry i am stuck for time right now, have to run, but i will do that later today if thats ok. I have a good quide for installing cpus. Actually you really cant align the pins wrong as the cpu will ONLY go in one way anyway, so its pretty easy with a socket 478!
    But i will help you out for sure.
    Same with Rage_3K_Moiz but someone else will likely do the same (or better) job as i can do, lol. But if not i will check it out for you as well.
    Sorry, gotta run.

    Ok so just power down computer, unplug the computer, take out old CPU, ground myself by touching the case, take out the old processor, fit the processor by rotating it until it fits in then close the lever and plug PC in and power up and test it? Seems easy :) Thanks guys!

    sw123, im back.
    Here are some tutorials on installing a cpu.
    Have a look and then we can answer any questions. Also i will give you my own brief tutorial.,GGLR:2005-37,GGLR:en&q=how+to+install+cpu

    The first is the main google page and the last three are taken from that page i googled.

    First, unhook the cpu fan from the motherboard. Then carefully take your heatsink\fan off, lift levers, take off carefully. Put fan and heatsink aside.
    The cpu will be under the heatsink\fan you took off. Look for a lever on the side of the cpu and lif it up so it points straight up in the air. Then use your fingers or a thin screwdriver to lift the cpu out, it should come easy. Note where the small mark is on the corner of the cpu so you can put new one in the same. Put cpu aside.
    Take new cpu and put thermal grease on it. I use a part of an old playing card to do this job but you can use a credit card or anything like that. Just cover the steel-looking part of the cpu, see the cpu you took out. Just a very thin layer on the metal part is all you need. Now the new cpu will have a mark on the corner. Put the cpu in the same way as the old one with the mark on the corner in the same place. It will ONLY fit it one way anyway, so you cant go wrong. Once the cpu is in place, flat, just like the old cpu was, then you can move the lever down and the cpu will be in place. Then put the new heatsink\fan on top and secure with levers on it, then plug the new fan onto the motherboard and you are all set.

    Now before you do this you should check your bios to make sure you have the right bios for your new cpu or it wont work. When booting up you can see the bios info, usually on bottom of the screen. You can use the "pause\break" key on your keyboard to halt the bootup to write down the bios info. Then go to your motherboard mfgr website and see what bios you now have installed. See if that is ok for your new cpu. If not, then you need to install a new bios BEFORE you install the new cpu. We can help with that as well. I dont recall if we already have your motherboard info or not.

    But, with my small tutorial and the pics you see in the websites i posted above, you should be able to do this yourself pretty easy. It seems scary, but its actually very easy!

    sw123, i was getting the pics and such and writing a tutorial for you at the same time you were posting and you posted ahead of me.
    Its not quite that easy but it is pretty easy.
    But first you need to check your bios!
    We can help if you give us the make and model and version number off your motherboard (mobo).
    And if you give us the info on your bootup as to what bios you have already installed. It may be you need to install a new bios or you may have the newest bios already, we need to know that info first.

    Also, once the new cpu is installed you may have to set the multiplier in the bios, but we will get to that once you give us the info on your mobo and bios.

    Thanks vnf4ultra, it looks good. Appears I have an older version of the mobo and the newer one(v8.1a) supports Prescott core CPUs. Would upgrading the BIOS to the new version somehow "Enable" support for Prescott core CPU? Check out the link below. V8.1a
