desktop CPU vs laptop CPU

[kujoe2002]

So I'm looking to upgrade my DELL. It uses the 1156LGA platform. I read that the laptop versions of CPU's are set to use less power and stay cooler. I'm not too concerned about power and battery life. I'm more concerned about the laptop overheating and catching fire. Can I use the standard 1156 quad core cpu or should I stick with the mobile version?

What model Dell laptop do you have?

Laptops only take the laptop CPUs, the exception being a few from Sager and others that actually put Desktop components in a laptop enclosure.

*Edit: Also, your laptops cooling solution is only rated for whatever TDP the max CPU configuration offered on the system is. So for example, if you could put a 45w Core i7 laptop CPU in there at the most, then 45w is the max TDP CPU your system can deal with.

*Edit2: If this is the same Dell XPS L501x laptop from your other thread, then you have an Intel i5 480M CPU. This is a BGA-1288 mobile socket CPU. This is not LGA1156.

I have a DELL XPS L501X. The specs are here:

*Edit2: If this is the same Dell XPS L501x laptop from your other thread, then you have an Intel i5 480M CPU. This is a BGA-1288 mobile socket CPU. This is not LGA1156.

As I said above, it's a BGA-1288 socket CPU.

As I said above, it's a BGA-1288 socket CPU.

Odd. I got this data from System Internals for Windows (SIW) and from

VMX, EST Platform Name Socket 1156 LGA Revision K0

I thought that was what I needed. Well if DO upgrade my CPU, what chipset CAN I use? Newegg doesn't show the BGA-1288 as an option. Also can I use a quad core for the mobo I have? I was hoping to install a true quad core running at at least 2.66GhZ. doesn't have to be an i7. But as long as it's a true quad core (4 physical cores).

Thoughts?

Here is what you can do, get a hammer and a chisel, maybe some vise grips to really shove the pins into the MB, then add a huge heatsink, this may require making a hole in the laptop casing...




Seriously, laptop CPU's are different than desktops, however, they may spit out desktop looking specs even with the mobile processor...your best bet would to be to contact Dell directly....

I have a dual core in my laptop running @2.8gig, if I go to a quad core the speed is reduced to no more than 1.6/1.8 gig to accomodate the extra heat of a quad....

The best upgrade for you lappy if you have not done it yet is to install an SSD, leaps and bounds on the performance....

laterzzzz.....

lol.... well the HDD I'd like to install is a minimum size of 512GB because the laptop can only fit one unlike the desktop. I'm definitely going to max out the RAM to 8G. The HDD I will probably install is:

Western Digital Scorpio Black WD7500BPKT 750GB 7200 RPM for 100$

But I'm not sure what the most powerful CPU I can get for my laptop that will be. It seems like based on what I read that I may already have the best core.

bummer on the single drive bay, many lappy's come with two drive bays now...

unfortunately, this means that a SSD of that size would be prohibitively expensive,,,

still best bang for buck as far as performance gains...

I was looking at the 10K RPM HDD's but they are just as expensive as SSD. So I went with a 750GB WD.
