Can I use these CPUs?

FuriousGamer · Aug 16, 2014

I have an Asus K55A laptop and I am looking to upgrade my CPU and have been searching about for CPUs on Amazon Because I don't trust Ebay. Is it possible for me to use these CPU in my laptop-
Intel Core i7-620M

And where can I buy CPUs other than Amazon and Ebay?

You cannot upgrade your laptop CPU as its soldered to the CPU socket.

Another "expert"...

Laptop CPUs can be changed, by desoldering them. You can't do it yourself, but computer repair shop / service can.

These are supported CPUs:

Intel® Core™ i7 3610QM
Intel® Core™ i5 3210M
Intel® Core™ i3 3110M

And probably other CPUs with rPGA 988B socket (Socket G2; FCPGA988).

And BTW, rPGA means that this CPU is not soldered (it has pins).

Thank you for the reply and do you know anywhere I can buy the CPUs?

Slobodan-888 · Aug 16, 2014

I think that you can only buy them second hand. So like eBay, Amazon, and other similar sites. It is best to find them in your local ads / sites (in your country), in case someone sells you a non working CPU:

I tried Ebay and I think the guy has scammed me that's why I would like to use different sites.

Yes only idiots like you would try to desolder it and damage the whole unit and cry here. Remember that your laptop was set up for that particular cpu and removing it can lead to problems.

Are you calling me or him an idiot?

rounakr94 · Aug 16, 2014

Is it worth mentioning! Since your laptop runs on a battery its not worth to change the cpu. If it was a desktop the that would be a different case.

You don't seem to know what you are talking about, So will just stick to the other guys replies.

Don't upgrade the cpu on a laptop

Laptops are known for being poorly up-gradable. Upgrade to an ssd and if possible get more ram. If you get a fast processor it will most likely overheat because the cooler is made for the specific one. Also, depending on the cpu, it may not fit in your laptop because of proprietary connections. If it somehow works, drivers will be a HUGE issue and your warranty will be long gone and it will probably kill it. On an alienware you can go through quite some difficulty and upgrade the gpu, but NOT THE CPU. Don't do it. If so, update me on the dead laptop

Intel said it should be fine as long is has a lower than the maximum voltage.

Pcbuilder123 · Aug 16, 2014

Best case you will need to update the bios, get a soldering iron and change it out and redownload the os and reinstall it. Why do you want to do this, by the way? You could much rather build a desktop or get a decent laptop instead

^Let him do what he wants, he is just one of those arrogant kids we come across everyday. But remember if anything bad happens we wont take any responsibilities.

Pcbuilder123 · Aug 17, 2014

Alright, sounds like a plan. Update us, though

The other CPU I originally ordered has been dispatched. when it arrives I will switch it and update you. Oh and another thing I am not arrogant just you are saying things that I know are wrong that's all.

Slobodan-888 · Aug 18, 2014

I would recommend not doing it yourself, but taking it to the computer repair shot. Even taking laptop apart alone is tricky.

For example, my low-end laptop is such a low quality construction, that after 3 disassemblys, it completely fallen apart (it is now mostly held by super-glue). Even screen hinges, that are made of (low quality) metal, broke.

rounakr94 · Aug 18, 2014

We'll see

Slobodan-888 · Aug 18, 2014

You really want him to fail, don't you?

FuriousGamer · Aug 18, 2014

rounakr94 :

Lol

Slobodan-888 :

Yeah he seems to be wishing for it.

I just got an update from royal mail. It is guaranteed to be delivered tomorrow, If I get out of bed in time.

Haha dude de-soldering a laptop CPU and installing a new one is SO much more complicated that you can even begin to understand. First off let's pretend you have the $1,500 soldering set-up that would allow you enough control to do this. Second lets pretend you are good enough with it to not overheat the solder joint (that is almost microscopic btw) while removing and re installing the CPU, instantly destroying the CPU and socket. 3 lets pretend you can repeat this process over 1000 times for all of the contacts on the CPU... Ok so if all of this isn't enough to scare you off let's address the facts that your laptops power delivery and cooling system was designed for that exact cpu in the system. Adding something that sucks more power and runs hotter will ruin your laptop. PS any shop who actually do this job properly will charge over $300 and that is worth more than the laptop.

There is no soldering involved with my laptop.

You don't know what youre talking about.

First, this cpu is in rPGA package. rPGA = reduced pitch pin grid array, meaning it is not soldered. It has pins just like desktop CPU, only the distance between pins is smaller.

Second, soldering/desoldering BGA (ball grid array) package components is done with hot air rework station, which can be bought for as much as 50 quid.

Third, soldering is not done by soldering individual balls at a time (which are not microscopic btw), but by heating up the top (or bottom, from the other side of the motherboard) of the CPU with hot air, until balls melt and solder the CPU too its footprint.

cmi86 · Aug 18, 2014

OK say that is true, what are you going to do about the extra voltage needed to supply that cpu that your motherboard isn't designed to supply ? Also what are you going to do with all the extra heat generated that the CPU cooler was never designed to dissipate. Go ahead man do what you want, ain't like I haven't been doing this for 10+ years. Just remember, we did tell you so.

Can I use these CPUs?
