Replacing cpu with cpu from other comp
(Click here to view the original thread with full colors/images)
Posted by: darkknight1223
I have an old comp from like 3 years ago and it's getting kinda slow. I have upgraded the ram, but the cpu speed is only about 400MHz. A while back one of my computers got all messed up and I couldn't use it any more. The only real problem with it was the motherboard, so it is unlikly that the cpu was damaged. Is it possible to replace my old computer's cpu with the crashed computer's 1.1Ghz cpu? My old computer was one of those mini-computers with an undersized motherboard. Do all cpus come in the same size? Also, can I use the built in heat sink from my 3 year old comp with my 1.1ghz. cpu? I dont know if this is relevant, but both computer were manufactured by gateway. Help would be greatly appreaciated.
-thanks

U will need to check the specs of the mother board which u want to put the 1.1 gig processor to see if it will accept the higher speed chip. I would not reccomed putting the old heat sink on the newer chip, it probably let it get to hot and it will fry.

How do I know if the motherboard will accept the processor?

you need to figure out what the brand and model number of the motherboard is, and then find the specs of the board on the net using google or any search engine.

How can tell the maximum speed for its cpu?

look up the motherboard online. the max cpu will be listed.
however, i think we can save you the trouble. a 400 is a p2. a 1100 is p4. they wont go on the same motherboard. that power supply would have a lot of trouble handling the load anyway. and the heat sink on a p2 is probably passive. the 1100 needs one with a fan.

What I posted before was what I found online from gateway.com. I couldn't find my motherboard anywhere else. Redwench, are you saying that the 1100 wont go on the P2 because of the powersupply and the heatsink or are you saying that they aren't compatible. By the way, the 1100 was previously on a P3 with a 90w PS. This is the name of my motherboard: "MBD PII /BX TB2 W/AUD"

near the crossover from one generation to the next, you can find compatabilities on some motherboards, but its rare. youve got a 3 generation span, that definitely will not work.
that power supply and heatsink wont work either unless you have no load, but thats not the point. the motherboard and chip are incompatible.
if that 1.1 actually works, get a motherboard for it, it will be under $50, and should make a decent second computer for a couple years.
Posted by: darkknight1223
My 1100 was made for a Pentium3. Should I buy a P3 motherboard? A Pentium3 would only cost 50?
Posted by: redwench
you had better get the model number off that chip. an 1100 might work on a p3 board, but its not a p3. then head over to intel's site and pick out a chipset, then go motherboard shopping.

I'll sum it up for you.
>Your old motherboard will not work.
>Your old heatsink will not work.
>Your old powersupply might work.
>If you buy a motherboard, make sure it's compatible with you're processor.
>To check if the motherboard you wish to purchase is compatible, check the motherboards box or look the motherboard up on the manufacturers website.
>You must take in to consideration that you're old powersupply probably won't be able to handle the load.
>You must also take in to consideration that you're old powersupply might be the wrong form factor.
>There are two form factors, AT and ATX. AT has two small power plugs, ATX has a single large one.
>Check to see which form factor the motherboard you want to buy is, and make sure you're powersupply is the same, otherwise it will not work unless you buy a new powersupply.
Baisically, to play it on the safe side, what you're looking at is a new motherboard and powersupply. The motherboard should run under 100$, if not under 50$, and the pwoersupply shoudl run you under 100$ as well. Make sure you get a 350w + powersupply, and that it's the right form factor.
ph34 teh typos. To lazy to proofread, sue me.

P3 1100's do exist, I've built one of those a long time ago. 
Posted by: redwench
they do? good god. my long term memory just aint what it used to be.

OK thanks for all the help everyone. Ill go searching for a new motherboard and ps.
