ScribeWare :
I would like to upgrade the CPU in my Dell Inspiron 17R N7110 laptop. Here is what I know at this time: The chipset is an Intel HM67 Express. That chipset supports both 4-core and 2-core Sandy Bridge CPU's which includes i3-2330M (the current CPU), i7-2640M (2-core), i7-2670QM (4-core), and i7-2960XM (4-core) as well as many other Sandy Bridge CPU's (see Intel's website for the HM67 chipset to see the complete list). You will need at least a 130W power supply and I have a 150W. My Inspiron N7110 has a G2 socket also known as rPGA988B or FCPGA988. The current i3-2330M CPU uses a (G2) PPGA988 and the i7-2960XM uses a (G2) FCPGA988. The FCPGA988 is pin-compatible with the PPGA988 (see Wikipedia for the G2 socket). The i3-2330M is 35 Watt and the i7-2960XM is 55 Watt. The power supply will easily support the difference. Here is what I don't know: Although the package size is identical for the i3-2330M and the i7-2960XM (37.5mm x 37.5mm) the embedded chip appears to be about 25% longer for the i7-2960XM than for the i3-2330M so that there could be a problem covering it with the existing heat sink. I have not yet torn it apart so I am not sure that the heat sink would work. Second, while I have the current BIOS revision (A13), I am not sure whether or not the BIOS would support the i7-2960XM. Any assistance you could provide would be greatly appreciated.
First of all, I am new here, so hello!
I do not know about the i7-2960XM and your particular machine... but I can say that the i7-2860QM works perfectly on my n7110 (I am typing this out on it now).
Before I upgraded from the previous i5-2450M, I went to the Parts-people... I am not paid by them, and get no kickback from them (I wish)... anyways, I used their free tool to search for compatible parts using the service tag from the sticker on my n7110. The i7-2860QM turned out to be the highest spec quad-core for my computer, so I ordered it off ebay and it is working fine!
Incidentally, I had the same question you had regarding the heatsink, so I called the Partspeople and their technician confirmed that if one sticks to the list of compatible upgrade options based on the service tag number, then there will be no problem whatsoever with using the original heatsink! I did however use grizzly kryonaut thermal paste to give it an edge.
I can say that upping from a dual-core to a quad-core is a HUGE increase in raw power/performance... I am so glad I finally did it!
If you do upgrade to the i7-2960XM, please let us know how it performs for you! Maybe I'll consider it a future upgrade for my machine if it works for you.
I hope this helps!

P.S. I know it is off topic from CPUs, but as an FYI, I also upgraded to 16GB RAM (even though Dell claims 8GB is the maximum). My system says that 15.6GB are accessible to my system, I can live with that!
