CPU and motherboard question

Tom Dunne

I have a socket 478 Celeron system (I know, I know). When purchasing, there was an option to chose the 2.8Ghz P4, the 3.0Ghz P4 and the 3.2Ghz P4. The chipset is made by ATI, as far as I can tell.

Given the economies of scale and all that, is it safe to assume that this system has the one motherboard that can take all the above CPU's, or am I completely barking mad on this one?

If I was to plug in a 3.2Ghz socket 478 P4, would it fry my 2.8Ghz Celeron system? If not, what is the worst that can happen?

Thanks,

TD.

This thread has my limited brain completly baffled. What exactly are you asking?

Chipset made by ATI......I don't think thats right.

Are you asking if you put a P4 into your motherboard that you where using for your celeron cpu what will happend. I assume the sockets are the same for both so it should work fine. Although there are several variables in getting the best out of your cpu like the FSB and ram etc.

I am basically asking can one socket 478 motherboard support all those different chips?

What I am also asking is if I take out my Celeron Socket 478 and replace it with the P4 3.2Ghz, socket 478, will it damage my motherboard in anyway?

As for the ATI, yes I know it sounds crazy, but I am using CPUZ (I think that's what it is called) and that's what it is reporting. I'll post the details up later when I get home.

Assuming that (as the mobo claimed) it can take a P4 2.8+GHz CPU then yup all you need to do is remove your Celeron and pop in the new one....

However make sures it is rated to these CPU speeds.... "ATI" don't do mobo's AFAIK altho maybe for OEM's

"ABIT" however do mobos... take a closer look at CPU-Z or try another util - SiSoft Sandra for example.

G'luck.

Allrighty, here's the output from cpuz:

Chipset

Northbridge ATI ID5833 rev. 2
Southbridge ATI ID434C rev. 0

I should point out it is a HP pavilion laptop. The processor is quite accessible, it looks like I just have to open 4 screws, remove a flap, so I might give it a go when I get my hands on the 3.2Ghz P4 tomorrow.

Right, Google was only showing me one hit that was in German, so I played around with my search. Eventually I found the following thread on a notebook forum:

Bottom line is he bought a 3.2Ghz HP notebook with the ATI 5833 chipset. Bingo.

Doom 3 here I come.

astrofool

not if you're using the integrated ATI graphics

Ahhhh ... it all becomes clear ... Notebooks are a whole 'nother kettle of chips.

As such I will retract my statement that is as easy as popping in a new CPU as I have no idea..... any notebook experts out there on CPU upgrades.....

If its a Laptop, you'll need to get your hands on a P4-m (mobile) CPU. Use CPU-Z to determine the chipset and then you'll know exactly what CPU's can be used.

How do I find out what CPU's can be used with my chipset? The ATI site has next to nothing on chipsets (it's an ATI chipset, see above for output from CPUZ).

After 30 mins and several new pairs of underwear, I am the proud new owner of a 3.2Ghz P4 laptop. It was actually quite easy in the end.

The only thing that caught me was the little lock thingy on the actual socket itself - I was trying to press the chip into the socket, only when I turned the padlock with a screwdriver did the chip fall into place.

And I have to say Doom 3 looks and plays a hell of a lot better (no pun intended)!

Is it a mobile processor or a desktop one ya put in?

It is a normal desktop processor.

I had no choice, really, they were giving them out for free at work.

I know it's going to hammer the battery, but that really doesn't bother me too much.

Dempsey

The battery will be hammered but will there be enough heat disapation. Mobile CPUs run cooler too.

Free at work? Can I have one

I reckon there will be enough heat dissipation. The heatsink is a crazy L-shaped jobby, with two fans (yes, two). It sits in the top-left of the laptop, with two vents. Scared the hell out of me, actually.

Yeah, my work laptop is a Pentium-M, it's the job. I get about 3 hours out of it on batteries. I wonder if I could to some sort of transplant....

Of course you can, not a bother. Form a queue.

Dempsey

Im in the queue, waiting

Tell how much harder the P4 is on the batteries than the P4-m when ya get some hours up on it
