1.2 ghz P4.

Why don't you do us a favor and give us the make of your mortherboard?

That's like me asking some one, "I have this ford, I'm too lazy to figure out what model it is and I'm too lazy to figure out the engine in it, but, what's the most horsepower I can get out of it?

Why not ask him to open the side of the case up, then look for markings, such as a name with the model right next to it?

I'm willing to bet that that cpu is a willamette. If that is the case (I'm 95% sure), then you're probably limited to no more than a 1.9 GHz cpu. I'm pretty sure that that is the highest they went before switching from socket 423 to to socket 478. Honestly, your best bet is to simply overclock the cpu...it's not even worth wasting the money for only about 300 or 400 MHz. Those original willamette were notoriously slow. In fact, the Tualatin P3 1.13-1.4 GHz cpus were better than those in everything except for a very few encoding operations.

tvdang7 - Sure no problem. That's what we're all here for. The people on this forum (most) are a great help.

I double-checked to make sure...they made the socket 423/Willamette cpus up to 1.8 GHz. Unfortunately, determining which socket/board you have will depend on other things b/c they re-released the 1.4 GHz+ cpus but as socket 478 cpus. I'm still willing to bet that your little cousin's is a 423 simply b/c they produced a crapload of those. The socket 478 ones that were produced in relatively larger amounts were the 2 GHz+ ones. The most famous one people loved to use was the 2.4 GHz one (in all it's flavors and revisions-bump to 533 FSB, bump to having HT, etc).

If you have socket 478 then you are in much luck as you will be able to upgrade to a much higher cpu. If you have the 423 then there really is no point in upgrading for 300 MHz. If you talk to your cousin, ask him to go to: Start>Settings>Control Panel>System and look for which one it is. It should say which one it is.

Use CPU-z to figure out what core it is. Most likely it is a willamette (Did they make 1.5 GHz Northwoods?).

Edit: Aparently there was a 1.5 GHz northwood, so make sure to download CPU-z and check.

It could be socket 478, or socket 423, but it's pretty much guranteed to be a williamette. If there was a 1.5ghz northwood I've never heard of one, but it's possible, especialy if this was an oem computer, like a compaq or HP.

If it's 423, you won't have much of an upgrade path, the fastest williamette wouldn't be worth it. As others have said, the williamette was slower than a P3 in most applications. so if you are limited to a williamette it wouldn't be worth upgrading if you are keeping the motherboard.

If it's 478 it's really hard to say since we have absolutly no details at all. It could be 400mhz FSB, 533mhz FSB, or 800mhz FSB. That gives a range of williamettes, northwoods, or even prescotts that could go on to a socket 478, but it's impossible to tell with no details. You didn't even tell us how old the computer was, what type of memory it uses, nothing, so it's almost impossible to tell you what you can upgrade too. SDRAM, RDRAM, DDR, far too many variables to have even the slightest idea of what the fastest chip that could go on it if it's a 478 board.

If it uses SDRAM, then it's probably a 400mhz FSB board that could support up to a 2.8ghz northwood, but be severely handicapped by the slow memory, if it's RDRAM it could be the 850 chipset or the 850e chipset, so it could support either 400mhz FSB up to a 2.8 northwood, or it could be 533mhz FSB for up to a 3.06ghz northwood. If it's DDR, it could be anything from 400mhz FSB to 800mhz FSB, so it could support anywhere from 2.8 northwoods, to 3.4 northwoods, and possibly prescott up to 3.4ghz as well. So you can see without more info, there is no good guess as to what the board can support..

You might as well be saying I have a car, it has 4 wheels, how fast can it go...

You'll really have to find out at least something about the computer, otherwise you'll most likely end up with something that doesn't work on the motherboard.

ok
He's using PC 133 SDRAM in a 100fsb motherboard- not a problem but not DDR mostlikley
he cannot have SDRAM and DDR so we gotta make a choice here, I'm using the 133 as the key

400 cpu bus 2.8 northwood
any way to get the motherboard make and model
how much ram?
how many slots?
how many pins or how long are the sticks?- amy markings on the ram?

actually the pc 100 sdram speed will work just as quick as DDR 200 so should not be a problem
perhaps with the pc133 he can run cas2 and 8ns cycle- but we're getting ahead of ourselves
Intel guys ---HELP

DDR-SDRam at 133 means it's pc2100 (DDR266).

I think northwoods are pretty expensive (not sure, though). If so, you might be better off replacing the mobo and cpu

then i would guess a 533 fsb P4 board? then he could get a 3.06 P4 right? might be able to pick up one of those used....although may need a BIOS flash to di it (im not too versed on ealry P4...so i could be wrong)

wow.........guys are u sure abou this?........he can go that high all the way to 3 ghz?.......from 1.5?.....once again thanks for the help...... he has 256 l2 cache if that helps..all this info is from him running cpu-z ....and his memory numbers are...2.5 3 3 6

ok and the motherboard mother is p4x266-8233 iono what the brand is

Going by this: link it appears to only support 400mhz FSB. I would play it safe and go for a 400mhz FSB 2.8ghz P4. If you try to put a 533mhz FSB cpu in the board, and it does not support it, it could damage the motherboard.

best quote ever btw...haha...cabbage. I would recommend upgrading your little cousins RAM and video rather than his processor...what does he use it for?

he says the mobo has elitegroup and pcnet on it... more help guys...help has been much appreciated

ok he has 5 pci slots and 3 ram slots...


ive done research...and.. ive condluded that he has a elitegroup P4VXAS
iono if he has atx or micro atx...but yea...http://www.ecsusa.com/products/socket478.html is where we can see the pics?....so any suggestions now?
