AMD 754 Desktop CPU in a Laptop?

Hey guys,

I'm bored of waiting for my craptop to boot these days and wondered if instead of having to fork out for a mobile processor like the Turion ML-37 I could stick a desktop cpu in there instead?

Its currently a Sempron 3100+ 1.8ghz, but was thinking of putting the Athlon 3200/3400 from a PC which are ten a penny. Being an Athlon rather than Sempron and probably a clean install will give it enough oompf to last me another 6 months.

Being a standard 754 pin config I cant see why it wont fit, and I dont care about battery life.....

Well you could, but it might get too hot and it might not be compatible with the mobo. They are both good chips, and neither eat much power, but is it even possible to source a new 754 3200/3400?

Also, a faster cpu won't make it boot much faster, you may not notice at all. A faster HDD and more ram in conjunction with a new cpu would help more.

If you disable your windoze splash screen by running msconfig and then checking the /noguiboot option in the boot.ini tab that'll help more.

You can also try things like removing programs from start-up that you really don't need. Things like quicktime, apple update, automatic updating services for drivers, ntune/bios monitors from the mobo manufacturer etc turn it all off and you'll load up faster.

often the laptop versions of chips will run at considerably lower voltages than the desktop ones, so bear that in mind.

and what pete said, a clean machine will make a lot more difference than 200mhz.

Assuming your laptop has a socket 754, you should be able to swap it in. The problem I see would be if the chip you want to put in there puts out a significant amount more of heat than the one that the laptop, it can possibly just consistently overheat because a lot of laptops are designed to operate with specific power dissipation and heat levels. It could just overheat and throttle down your CPU so it doesn't melt, or it could overheat everything and ruin your mobo and RAM.

Thanks for the balanced replies.

I've generally found Laptop cpu's tend to run hotter than their desktop counterparts so I'm not massivley concerned on temperature problems.

My main concern was voltages etc etc, but I think I'll just stick one in and give it a go. The 3200/400 can be picked up on ebay for a few quid being such an "old" cpu....

The laptop has 1GB (2x512) of dual channel ram so I think it's OK there.

Once again, thanks for the replies, If it fries I'll let you guys know lol!

Quite the opposite.

Look inside any desktop, and you'll find a heatsink big enough to beat someone to death with, along with an 80mm or so fan.

Laptops just don't have anything like the cooling capacity of a desktop, so stuff runs right on the edge of safety, as they can pretty much rely on the laptop to last 4-5 years, never get an upgrade and be replaced as soon as it dies.

I'm not saying it definitely won't work, but it might make bad things happen.

:above: all of this is 100% of fact
