Hp dv7 6135dx cpu upgrade

[KDMMods]

Ive been looking into this for a few months now.  I've been doing some reseach but i just want to make sure everything will work.  I currently have the I5 2410m and id like to go with the best cpu for this socket which is the I7 2820qm.  My one friend said HP has a Bios lock on the cpu.  I feel like that isn't true.  I found one for $60.  Is that a good deal?  Thanks!

Your best processor is

Intel Dual Core i7-2620M 2.70-GHz (turbo up to 3.40-GHz) processor (1333- MHz FSB, 4-MB L3 cache, 35 W) 631252-001

There are different motherboards for dual and quad core cpus with your 6490 chipset. 

See the Manual page 27-28

$60 is a good price for the Quad, but will not work with your motherboard. 

The i7 dual core would provide about a 20% bump in processor power:

No processor BIOS lock. Good luck and post back if you need any more info or help. An SSD would be an easier upgrade and likely as effective or slightly more so, although more expensive if you are doing the labor on the CPU.

To replicate your work, I looked at:  https://support.hp.com/us-en/document/c02845403

which states that the original processor is: 2nd generation Intel Core i5-2410M Processor 2.30 GHz with Turbo Boost Technology up to 2.90 GHz

Specifications for that processor: https://ark.intel.com/products/52224/Intel-Core-i5-2410M-Processor-3M-Cache-up-to-2_90-GHz

Product Collection:  Legacy Intel® Core™ Processors 
Code Name:  Products formerly Sandy Bridge 
Vertical Segment:  Mobile 
Processor Number:  i5-2410M 
Launch Date:  Q1'11 

Performance
# of Cores  2 
# of Threads  4 
Processor Base Frequency  2.30 GHz 
Max Turbo Frequency  2.90 GHz 
TDP  35 W

Graphics Specifications: Processor Graphics ‡  Intel® HD Graphics 3000

Package Specifications - Sockets Supported  FCBGA1023, PPGA988

-----------------

I think that the most-important required attributes are:

* "Core", not "Core2",

*  integrated graphics processing,

* "mobile", not "desktop",

* maximum TDP of 35W,

* same pin-outs, to fit the supported sockets,

* dual-core, with hyper-threading.

But, given that you currently have 4-way processing, how often will your software simultaneously exploit all 4 threads, and exploit 100% of each thread? Will you be "wasting" money, by needlessly upgrading the processor?

Thanks alot.  I didnt know there were two different mobos for dual and quad core cpus.  Not sure if its worth the 20% increase.  I can always do it some other time.  Thanks again!
