i have a pavillion DV6-2155dx and want to upgrade the processor from a I-3 to an I-5 or above.

Amazon.

you can find some around 130$ USED

its kind of hit or miss.

Sometimes you end up getting one with slightly bad condition and would not know if it will work or not until you install it.

And from my experience..opening HP laptops is a b*tch.

you can guess the rest.

I ended up buying quanity of 4 just incase I get a bad one.

Check for the latest bios revision and what cpu support changes have been made F1CA REvision, Now supports core stepping K0 cpus.

1- model and serial #

2-Cpuz free software Helps id your motherboard , bios version ,memory,cpu,chipset,ect.........

3-Manufacturer's Websites some times you have to do some digging but eventually you learn something intel, amd,nvidia,ati,mac,ect,ect...........

4-Wiki is another great site for info on anything also

5-Always check for bios udates at manufacture website in support section for your product.

6- system info in windows is also very useful on pc info and errors.

7-Always check multiple sources!!!!

BIOS vF.1CA for DV6-2155dx or newer installed in your notebook.
Fix/Enhancement:
Adds BIOS support for the Intel Core i5-520M, Core i5-540M, and Core i7-620M K-0 Stepping Processors.

Intel has released a new K0 stepping for some of its older dual-core Core i3 and Core i5 processors, as TPU reported. The new stepping will apply a few tweaks and updates within the CPU architecture. Perhaps they OC better as well. These chips will be available on October 16, 2010.

Compared with C2,change for KO is as follows:
* New S-spec and MM numbers for the converting products
* Extended CPUID will change from 0×00020652 to 0×00020655
* Host RevID will change from 0×12 to 0×18
* K0 stepping package is pin compatible with C2 stepping package
* Adds Processor Context ID (PCID) support
What is the difference in term of performance between C2 and K0?
Thanks in advance for any suggestions
