where to find the core i3 2357?

the story is, my friend bought a Core i7 laptop! a cpu that he doesn't need! but also love the 18" laptops, so convinced him to switch to a lower cpu without sacrificing the gaming performance and more battery life instead of selling it and buy another one!

anyway this sweet little cpu that only consumes 17 watts isn't for sale anywhere! I've checked on ebay and other retailers! if someone would lead me where to get these I'd be appreciated! I'm sure there's someone to sell, this is the internet after all

thank you!

 

That would be a low voltage processor that is soldered onto the laptop's mainboard. Your only option is a 35 watt i5 dual core.

 

It is going to be interesting to see how this turns out with the OPs friend.......

Trying to change out or upgrade current generation CPUs, even when they fit the mobo (which in this case it DOES NOT) is a hellishly expensive undertaking.

The i3 in question is an OEM only part; you need to have a bulk-purchase/manufacturing agreement with Intel to get them. Usually, the min order quantity is 1000. Any BGP processors you might find on the market have likely been diverted from authorized manufacturers (surplus or rejected/marginal/bad) or have been stripped from salvage.

To make use of one, you'll have to develop some serious soldering skills and hope to hell that none of the prepositioned solder balls were knocked off by rough manual handling. BGA packages really aren't intended to be touched by human hands; they are designed for machine handling from the shipping/storage tray through process equipment to automated soldering.

And be prepared to fully void any remaining warranty of the target machine.

A 17 watt TDP bears little relationship to the actual power consumption or potential battery life. The 'T' in TDP stands for thermal; TDP is intended to be used as a design/budget point for the implementation of cooling solutions (heat sinks, etc), not as a guideline for power consumption.

 

Sometimes you can find those BGA soldered CPU's in PGA form (only on Ebay). Last generation Arrandale was more difficult to find. I know Commander_Wolf had a PGA SU9600, and they weren't that expensive on Ebay.

 

Actually the best place to get CPUs like this is b2b sites like Alibaba.com.
This seller has a MOQ of 3: Core i3-2357 products, buy Core i3-2357 products from alibaba.com Also they have 3 different versions, one of which may have pins.
Although they also have a warning about companies that sell fake cpus with the pins soldered on, sometimes Intel is simply wrong about what is available in PGA form - so there could be a version with intel pins.

However, this is a really dumb idea simply for the fact that you lied to your friend - 1.3ghz? He'll DEFINITELY see a drop in gaming performance. No question.
Just grab a 2310m for him, it will be cheaper anyway. And, all the other components in that 18.4 laptop will probably screw the possibility of battery life past a certain point.

Wow @ newposter I love how the less you know about something the more you like to lecture on it.
What is a BGP CPU? Ball Grid Pin??? seriously.

You don't sound more intelligent just by trying to correct other people or set people straight.
Surplus/rejected/marginal/bad. Wow, that makes lots of sense. Do you REALLY think, if someone was trying to scam you they would go through the trouble of shipping you a bad CPU?

There would be absolutely nothing bad about a BGA ball falling off, seeing as how many BGAs come without balls when they are sold, and anyone who has use for a BGA obviously has BGA soldering equipment! Seriously, dumb.

Yes, there is very little relationship between the lower voltage and frequency at which these CPUs run, the TDP, and the wattage they consume. Right.
If incandescent lightbulbs ratings were their TDP rather than the actual consumption, but an estimated 99% of the wattage they consumed was heat output, would you just not even consider replacing a 100w with a 60w if the 100w blew your fuse every time, because the 99% is an estimate and its only the consumption that blew the fuse?

....Seriously!

 

Read Intels docs on BGA handing.........

 

Serious soldering skills? It is reflow soldered. The same thing people do when they bake their GPU. Also pre-positioned solder balls? What are you talking about? The loose balls are put into place just before soldering. You can place them and the chip by hand if you feel like. It makes no difference.

 

Yea, exactly ^
Don't tell him, he thinks the green part of CPUs are just tiny compressed PCBs with 12 layers and millions flat SMT transistors.

Ideally you start with the BGA unattached and use a stencil to position the balls perfectly.

It would actually be REALLY easy to add pins if you had the right kind of stencil... and pins. No idea where you'd get those tho lol.

You could just stick a dead CPU to the new one, then try to heat the dead one more and see if they came off on the new one.
