question on replacing cpu

Well, I've seen many "how the noob broke the computer" threads, but this is a new one to me, and I could use some help from you guys.

It all started with my brother trying to clean his computer. He decided that he could probably clean the heatsink a lot better if he took it out. Should be easy enough, just pop the latch and the heatsink should come right off. Well, the thermal paste must have been on there pretty well, the thing needed a bit of encouragement to pop off. According to my mom she could hear something crack or pop from across the room. Turns out the processor stuck to the heatsink, breaking off four pins on the processor.

Long story short, he found and ordered a new processor that was supposed to fit, and it didn't. Finally he ended up asking me for help, but unfortunately, I dont' know much about processors, so now I'm asking you.

From what I could read off the old processor, its a 478 pin 3Ghz pentium 4 sL6wk malay with 512K cache, and 800 Mhz fsb. From looking around, this processor seems to have been discontinued, so he'll probably need a newer chip, the question is what will work?

Would any other 478 pin 3 Ghz chip with 800Mhz fsb fit, or is it not interchangable since this is a Dell mobo?

If there's any info I didn't post, feel free to ask, and I'll get it. Thanks in advance for any and all help!
 
that is a 800MHz FSB northwood core cpu, looking around in retail seems a little hard to find...

both prescott and northwood cores come in a S478 package, and he needs to make sure he didnt get a prescott core cpu because the motherboard in the dell may not support it ....

as long as he got a S478 cpu it should go in (because it goes in doesnt mean its compatiable because what i mentioned above with the prescott core cpu) , it can go only go in one way, he has to look at the pin outs to see which way it goes in, also it should drop right in and should require any force to go into the socket....

but you said he broke off several pins, they still may be in the socket and need to be removed... he may need to take some tweasers to get the pins out (if he cant get them out with tweasers he can try a magnet to try and pull them out, but using a magnet near sensitive computer parts is risky imo)
 
i didn't know that they made 478 cpus with 800mhz bus? try finding one at ebay, you can get lots of older cpus there.
 
heck yeah 478 pin cpus are 800 mhz.

Northwoods can be had plentifully on ebay, they have 800 mhz northwoods in your speed range.

I would be surprised if a prescott cpu didn't work in that dell board anyway. Prescotts can be bought in the 478 socket grid pattern too and since Dell uses Intel motherboards, almost certainly a prescott could be used as well.

I still suggest a northwood, because clock for clock they are faster and cooler.
 
<--- S478, 3.2GHz Prescott, 800MHz FSB chiming in :). They do in fact exist, and aren't that difficult to find honestly.

yes, S478 prescotts are easy to find, but this is a S478 800MHz FSB Northwood that is not so easy to find(at least in retail)
 
any board that supports 800fsb should support prescott chips, but you might need a BIOS update...

easy way: get a northwood off ebay
hard way: find a bios flash from dell, see if a prescott will work, buy a prescott retail.

I go to school here at Embry-Riddle (see sig ;)), so right on Clyde Morris Blvd... only a couple of miles from I-4. Where'd you go to school at?

good ole 600 South
 
Thanks for all the responses! Well, after hearing all this, I feel the easiest and cheapest way will be the ebay route. He may have to get a downgrade to 2.8 or 2.6 Ghz, as I don't see many at 3 on ebay right now.

Now I have a second question, is the old CPU salvageable, meaning, can it be sent back to Intel and have the pins resoldered? I just feel that it's a waste to have a processor just sitting here if it can be fixed.

Thanks for answering my questions!
 
nope.

you can try to put it back in teh board and see if itll post (sometimes itll work, he might have just broken ground pins), but intel will not fix physical damage, and only warrants CPU's you bought retail, in the retail package... and the OEM wont touch it.
