L520 Cpu Upgrade

Hello, i have a Lenovo thinkpad L520 and i'm looking forward to upgrade the cpu (Pentium B960, Intel HM65 mobo). I have some questions regarding this:

 

  • Is the Intel core i7 2630QM the top processor that i can go with, or could i try something like i7 2760QM, i7 2860QM or any other similar quad core processor with same TDP 45W, same socket, same stepping? (I suppose 3rd generation cpu's are not compatible, right?)

 

  • Is the Turbo Boost feature on these cpu's going to be fully functional?

 

 

BIOS Version: 1.23 (8GET46WW)

 

 

Links: Intel Core i7 2760QM

            Intel Core i7 2860QM

            Intel Pentium B960

Re: L520 Cpu Upgrade

Hello.

 

Thanks for the reply.

 

I had already checked the detailed specifications page before i made the initial post. I know that i can upgrade to i7 2630QM.

 

My question is, can i upgrade to something better than that such as i7 2860QM or i7 2760QM?

 

Also i wanted to know, wheather the Turbo Boost feature will be working or will be blocked by BIOS, after the upgrade.

 

I can understand If there is no way for you to know this, but if you do, please let me know. Otherwise i will just stick with the i7 2630QM.

 

Thanks!

Hi Scha,

 

Thank you for the reply!

 

I am sorry to inform you that your system will support i7 2860QM or i7 2760QM. As I informed you that you can stick to i7 2630QM & this your turbo feature will work with this, you can enable this feature from BIOS and after that you have to install Intel turbo boost application.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: L520 Cpu Upgrade

I, too, am thinking of upgrading my cpu on my L520. It is an i3 2350M. If I go to either of the i7s listed (2620M or 2630QM), will I have to update the cooling fan, too? Thank you for your answer.

Re: L520 Cpu Upgrade

Sorry it took so long to reply ... somehow my profile was changed so that everything was in German, a language I do not speak. I've changed my profile back to English and now I know which button to click ...

 

The L520 is a 5015W1M. I purchased the laptop used, and I notice that the laptop presently has an i3-2350M. All the spec sites indicate that the original CPU was the i3-2310M, so it appears that the lapop may already have a minor upgrade. I presently have 6 GB RAM. I'd like to put an even more powerful CPU in the laptop (for video editing purposes) and the link above gives the following as possibilities ... i5-2520M, i5-2540M, i7-2620M, and the i7-2630QM. All are available on ebay for less than $100.

 

Are there other possibilities AND will I need a new CPU cooler fan? Additionally, how value would I get if I update to 8 GB RAM?

There's only one fan model for the L520, I'm not sure though how efficient the cooler will be with a quad CPU, but since Lenovo offered a quad option for this model I guess it will be ok (or with a marginal cooling difference)

 

The biggest performance jump will be adding an SSD. Since you plan to upgrade the CPU I would add more RAM as well (8GB is very affordable these days)

I'm surprised you were told so. While Windows may go bluescreen when swapping the CPU a quad is fully supported (see hemanth link on post #2)
