CULV cpu upgrade question?

So, I have samsung x360 using the Intel SU9400 cpu which a 1.4ghz cpu. I was wondering if i was possible to upgrade to the cpu that the MBA and a Lenovo U110 use. I googled it and its called the SL line. Im thinking maybe the SL 1.8ghz cpu. I saw the first model of the MBA line used the SL with the x3100 intel gpu that is how I got the ideas. Thank you.

 

It will take hours to do and you'll loose battery life. The process would be really hard. This is the processor that is 45nm and runs at 1.8GHz, not sure if it is in the MBA though. 7W increase in power usage over a SU9400.

 

Why not just wait and see if a 1.8ghz SU9x-000 model comes out? Then again how much less battery life would the 7w power increase be?

 

Aren't the SU CPUs soldered onto the motherboard?

 

I was told some aren't. I heard Sony doesn't do it so I though maybe samsung doesn't either? Plus the SL is more speed with out too much extra power. I get 9 hours out of my x360 with the larger battery, what will I get with this new cpu 6 or 7 hours?

 

What about this I hear intel makes a better 4700hd gpu, that is faster, and more efficient, anyway to do that to my gpu out of curiosty?

 

It's not more efficient, it's just overclocked.

 

So what about if I go for the Sl 1.6ghz cpu? Is my cpu realy soldered on?

 

I would say 85% it is soldered on. Do you have a source for purchasing an Intel SL series CPU? Please post any links.

 

Try ebay? I know for the Sony devices, I have seen an ebay service where you purchase the cpe. Then you give them your laptop and cpu you want installed that WORKS on the devices and for a fee they install it on your machine. Shame they don't make a 2.0ghz SU line cpu, cause I would have it in my device right now.

 

What do you use your notebook for? A 1GHz CPU is sufficient for most people's usages, especially to those with a CULV.

 

So, I read th that the intel SU7300, which I read the SU7300 and SU7600 used in the older LG X100 is faster but has just a bit more heat? It due to something called cache(which i thought was an interent thing), and faster FSB. Is this true?

 

bump please?

 

culv uses a bga socket, so it's soldered on to the mobo. you can't upgrade

 

one can't un-solder it?

 

i have one app that doesn't run on a 1.2ghz c2d fast enough for being useful. it's a special app costing 1000$, called ableton live, for live music performances.

other than that, the 1.2ghz c2d performs very fast.

if you don't need a fast CPU, consider buying an ssd instead. gives you much more speed gain, helps everywhere, even saves battery. and is much simpler to change than the cpu.

so, again, do you really NEED a faster cpu, are you cpu limited?

just as an idea..

 

I have the 1.4ghz. I do a bit of video editing on premier elements and music on Sony Acid.

 

video editing could gain from a faster cpu, sony acid, well, only if you're at 100% cpu during usage, getting sound-glitches or what ever (most likely not..).

but the video editing could at it's best cases (there, where the cpu is limiting, f.e. at the final saving with the re-encoding) 28% faster (most likely not as it's often memory limited, too). while editing, again, if it doesn't really stutter, no gain.


if one of the program stutters or lags really hard, and you see your disk activity glowing or flickering while it stutters, it's NOT the cpu bottlenecking (you should then not see a 100% cpu usage pike in the taskmanager).

then, again, consider an ssd, or just a faster hdd.

if you think your system is slow, but it's not at 100% cpu usage while you experience the slowness, don't consider a cpu upgrade, it won't give you any gain.

and saving a big movie project that takes one hour right now would still take 45minutes after the cpu replacement, so you still wait for ages => even while there is gain, it's no wow-effect gain at all.

 

You've absolutely no chance of desoldering/soldering a BGA component without some serious equipment. Any attempt to do it by hand is very likely to destroy both component, board, or both

 

So, lets say it was a soldered BGA component, could one upgrade to the SL line cpu from the SU cpu?

 

It's practically impossible to upgrade a soldered BGA component.

 

You can do it if you have access to about $25,000 worth of equipment.

 

Opps I meant to put out a theoretical question saying: lets say it wasn't a soldered BGA component, could one upgrade to the SL line cpu from the SU cpu?

 

Where are you purchasing the replacement CPU from?

 

All SU, SL, and SP chips are soldered onto the same FCBGA6 "socket".

 

I was just wondering, since the OP brought it up.

 

First, you would need to check the availability of parts. Even if you found the CPU, it would probably be BGA like above said, and you would need to solder it yourself. There was a case I read about where someone upgraded the soldered on RAM by removing and soldering on 4-8 higher capacity RAM chips from the same company.

 

Well I did see an ebay service, for Sony computers that suppose to reputable that upgrade what ever you can on your machine and I think it said they do cpu upgrades for the TT. However, you have to provide the parts you want upgrade and they do the upgrade for a small fee.

 

If the chips were BGA, that's hardcore!! Huge respect is due.

FWIW I consider myself a skilled soldering iron user, who has no problem doing SMD (surface mount) stuff by hand, but not only would I be totally incapable of doing a BGA, I wouldn't even know where to start. If anyone is unsure why, have a good look at how a BGA component is actually soldered and it should become clear!
