can i upgrade from i5 to i7?

i want to buy a hp Pavilion 14-n223tx TouchSmart but i need it in i7 and the original core is i5 so i was wondering if this laptop model can be upgraded to i7 and the best i7 model to use.

 

You can only buy what is available - if you modify an i5 based system to use an i7, that is a frankenbuild.

It may work perfectly, not at all or not stable or reliably because of heat, BIOS, chipset or other manufacturer limitations, compromises and design decisions.

You can wish for things to be as you want. But act on what is real and attainable now.


Good luck.

 

in your case, you cant it's an ULV cpu and most likely soldiered on the motherboard .. anyway the ulv i7 are not that fast comparing to their i5 homologues..

 

i5-4200U is a BGA soldered CPU, there is no upgrading it. Unless HP has a CTO version of that specific model (which it doesn't look like) and doesn't offer an upgraded version, there is no upgraded it. And as sasuke256 has pointed out, the difference between the dual core i5 and i7's even Haswell chips, it isn't that much faster.

 

Personally, I wouldn't even bother even if it was possible... (as sasuke256, Tsunade_Hime, and tilleroftheearth mention).

Anyway, if you're looking for a CPU upgrade, sell your laptop and get something with a full-voltage, quad-core i7. That would be the only meaningful CPU upgrade. However, depending on what you're doing, you'd likely see much more benefit from just upgrading from a mechanical hard drive to a solid-state drive instead of a CPU upgrade.

 

no. as #4 said its a bga, unless you can resolder it.

 

AND the firmware supports it.

 

I bought a Sony VPCEH laptop from ebay with a fairly good price (I think... ), with i3-2350m, 4gb, 500gb hd and blu-ray. I upgraded it to 6gb, 128gb SSD and Windows 8, I am quite satisfied with its performance, as I am not a very demanding game playing user, the application I use is Office, watching video and at most lol.

Until recently I came across some forum talking about the i7 CPU upgrade of IBM ThinkPad, I started to wonder if my Sony laptop can do the CPU upgrade. I then started to do some research over the internet, but then I found there are so little information about this and so few people do mentioned about Sony CPU upgrade. I sent an email to Sony but the reply is not recommended at all and no info provided from Sony officially.

After doing some research, as my Sony comes with HM65 Chipset with G2 Socket, and also taking the price of i7 into consideration, I dare to have a conviction that i7 2820QM (I am not dare to try higher model at this moment... ) should work with my Sony laptop. There are 2 unknowns that I most concern: The TDP of i7 2820QM is 45W and for i3 2350m is 35W, so there is a heat issue concern. Another one is about the Bios, even everything fits but the Bios may have a chance not recognizing the CPU.

I tried several bid of i7 2820QM on ebay but not successful, and I found at this moment, the trend of the price of i7 2820QM is around US$150-$200, which is comparatively expensive as it is almost about the price of my whole Sony laptop. After a while, I came up a chance to find a listing on Craiglist an i7 2630QM CPU asking CAD$80 (US$70). The performance of i7 2820QM is far more better than i7 2630QM with higher clock speed and internal Cache etc. but the price of i7 2630QM is very attractive, it is more than 50% off from i7 2820QM, After some negotiation, I got the very good deal of it CAD$60 (US$50) and the time comes to give it a try.

I carefully dis-assemble the laptop, remove the old i3 CPU and then put in the i7 CPU, re-applying the thermal paste and pad, clean up everything, re-assemble the laptop, it takes about 15 mins. Everything is in its place, before I press the start button, I did a prayer and then.... bloom....it WORKS! Thanks God!

The performance is AMAZING! The Windows almost started immediately, I run the Speecy to monitor the heat problem, it is about 45-52'C when idle, watching HD video not much difference, when playing lol, it comes up to 72'C. Up to right now the heat issue seems like to have no problem.
I tried some applications, the speed is noticeably improved, this is my 2nd day of the upgrade, everything works fine, so excited and so amazed, I upgraded an laptop from i3 to i7!!! Can''t wait to share to all of the Sony fans!

 

When in doubt, one of the fastest ways to check if the upgrade is possible is to see what hardware the manufacturer put in "high performance" models in the same lineup.

My mom has a Sony Vaio that just turned 4 and had slowed to a snail's pace. Slow HDD aside, I discovered that Sony cheaped out and used an 800MHz FSB C2D (T6600) chip even though the Vaio was running a PM45 chipset, which meant it could take 1066MHz FSB CPUs. I wasn't sure which of the 1066 C2D CPUs were supported, so through the magic of Google I dug up the service manual for her laptop series, and saw that both the T9600 and T9900 were offered on the high end models. Then I cross checked the BIOS and turns out all the models in that particular lineup ran the same BIOS. So I bought a T9600 off Amazon and popped it in. Machine botted without a hitch, and everything felt snappier (though still relatively slow).

 

Excited! I just upgraded from i7 2620qm to i7 2820qm, as I have just got another good deal of it, it is SUPER fast, and thank Sony, it recognize the new CPU right away and handle the heat very well, the laptop keep in a good range from 45 - 55.
