Upgrade processor Toshiba L650-11F

Hi, I would like to change the processor in my laptop. In this moment I have i5 430m, I would like to mount I7 720qm, or i7 740qm.
Temperature will look like? Wants to use thermally conductive paste Arctic Silver 5, and clean my laptop, because it was not cleaned.
Which processor will be better for me 720 or 740qm ?

I'm sorry for the language, I don't speak english good, I use translator

Please answers.

Thank you, greetings

 

very little difference between those two.

 

Neither would be good. You are far better off with an i5-560m if you must upgrade as this will give equal or superior performance to the i7-720qm without the power and heat concerns. I would even consider the i5-580m or i7-640m as these give very good performance for their power consumption and heat.

If you must get a quadcore i7, I recommend the i7-920xm but I warn that your Laptop doesn't have the cooling required.

 

No, I don't need a 920xm. I know my cooling its too weak. But I want quad core, now many applications use quad core and quad core its easy for buy in my country (Poland)

 

I understand where you are coming from but there is a weird quirk of the Nehalem (specifically Clarksfield chips) you have to know
I'll put it this way:
Lets assume the CPU can do 1 operation per mhz.
The i7-720qm can do 1600 operations at peak speed per core
with 4 cores it can do 6400 operations

The i5-560m can do 3200 operations per core at peak
with 2 cores it can do 6400 operations

You can see that the i5-560m can operate at the same output theoretically. In practice it is very easy to code an application to run at 95% efficiency across 2 cores while it is difficult to make an application run at even 80% efficiency across 4 cores.
Therefore, the i5-560m is more likely to utilize its full potential output with little optimization while the i7-720qm is lucky to have 80% of its output in well optimized applications.
Therefore, because the i7-740qm is slightly faster than the i7-720qm, you can consider the 740qm to equal the 560m. So why would you consider the i5?
The i5-560m also brings a few advantages, better single/dual thread performance, it runs cooler, less power consumption (about half in fact) is readily available on ebay (even OEM models) and we know for sure it will be compatible with your laptop (because you already have a 430m)

And the best part about the i5? it has an unlocked TDP/TDC (the i7 doesnt) which allows you to force the chip to have unlimited turboboost with Throttlestop.

I understand that the i7 may be easier for you to obtain but I strongly suggest you consider the i5-560m since it gives you the same performance with less chance of problems. We actually have one member posting already about an upgrade gone wrong since he upgraded from the i5 to a quadcore i7. Trust me I have owned an i7-720qm and that chip has really bad performance for the amount of power it uses and heat output.

Some boards may whitelist 45W quad core CPU's so I'd be wary about installing any i7 quad core chip unless a similar model has an i7 option. Also if you don't have discreet video, the 1st generation Clarksfield i7's don't have integrated graphics on the chip so it may not work at all.

 

I think these are your biggest concerns to take into consideration. That being said, if you don't have discrete graphics, your better upgrade option out of what you're considering would be the 430M..

Remember that BGA is not an option, since BGA is used for soldering the chip to the socket. The 430M comes in PGA and BGA packages.

 

I'll give the rest of the laptop specifications:
I5 430m
8 gb ram 1066, but this RAM max speed 1333 MHz. I think it reduces the CPU, because i5 support max 1033 MHz
Ati 5650 1gb Oc 565/975
HDD - nevermind

okay, think about my choice between i5 and i7.
But I have another question, if I really buy i7 quad is my bios supports i7 processor ?
I have InsydeH20 3.5 REV 1.20 Bios. Where do I check this?

That is a fact when I don't use multicore aplications, games i5 its best choice, but when I will use multicore i7 wins.
I mostly used a laptop to play, yes of course my GPU its a weak but I optimal play in medium detail.

The thing is, the i7-720 & 740qm had clockspeeds that are too low. This means that they will only match the i5-560m in multicore applications while giving you none of the high clockspeeds for dual and single thread apps (e.g. games).
Its not until you get the i7-820 or 840 thats when you get a performance lead over the i5s in multithread applications. Even then, these chips are horrible because their TDP of 45W is so limiting that they will virtually never turboboost unless you have a really good cooling system (I'm talking Alienware level). Therefore you get really crap dual and single thread performance.
That is why I said that if you had to get a quadcore, go for the 920xm, it will give you the high clockspeed of the i5s plus good multithread performance AND is fully unlocked but the heat and power requirements are massive.

Your BIOS will probably support the chip but your cooling system might not, you might notice spontaneous shutdown after 30 minutes, overheating or stuff like that. Check out some of the other threads, we've had people upgrading their Toshiba machines with i7s ad having problems.

 

You can have a look here. But just tread softly; BIOS mods are not something you want to take lightly.

 

Could you give some about such problems, or forum Description in which he is? I can not find anything that would fit.

 

I have new idea, because I read this topic http://forum.notebookreview.com/har...ully-update-hardware-but-help-me-plzzzzz.html and I doubt I have enough cooling. I'm not going mount additional heat sinf, and fan. Returning to the idea, I thought about installing i5 580, or i7 640- both i5 and i7 have TDP 35 W that is, as much as my 430m.

Which of these two is better?

 

Definitely either will be better than the i5-430m. The i7 can boost to 3.46ghz on a single core but only 3.33ghz on all cores which is the same as the i5. Technically, the i7 is slightly better at single threads due to the extra 133mhz but II would choose the i7-640m only if it is within $20 price difference. Otherwise, the 580m is the best bet. Don't forget to check out ThrottleStop.

 

Okay, I decided to change i5 to i7 720qm. I use good thermal paste (Arctic Silver 5), and I have hope it will be all good.
