    Hi!

    I'm looking to upgrade my Dell Precision M6700. I have a 980M 8GB GPU on the way, and I'm looking for a decent CPU to go with it. I was wondering if anyone has experience with a combination of 980M 8GB + i7-3940XM (or similar) on the M6700 with any success? I guess what I need to know is:

    - Will 980M + 3940XM work?
    - What's the optimal CPU for 980M on the M6700 (if not the 3940XM)?
    - Would it be worth getting a 330W power brick (does the M6700 even support this)?

    I don't plan on any pointless overclocking. From what I've read I won't need any heatsink modifications, just 1.5mm and 2mm thermalpads for VRMs, etc. Doesn't look like I'll need BIOS rewriting or whatnot (I hope) - the GPU I ordered was pulled from a Dell machine.

    Yeah, 3940XM would be great in it. In fact, that was a factory-installed option. Should work flawlessly. https://www.notebookcheck.net/Revie...00-Notebook-Nvidia-Quadro-K5000M.89984.0.html

    There is not a more powerful CPU that would work. Check with Dell Spare Parts (quick phone call) to see if the 3940XM needs a different heat sink. Alienware notebooks used a 3-pipe heat sink with the 3920XM and 3940XM.

    Not sure if 980M will work or not. It never worked well with the Alienware notebooks of the same generation. Maybe someone has already tried it and knows how to respond to that. If not, a 780M should work and still be a decent upgrade. But, 980M (if it will work) would be much better.

    Edit: appears it will work... http://forum.notebookreview.com/thr...980m-upgrade-windows-10.789235/#post-10478671

    Quadro K5000 vs GTX 780M vs GTX 980M

    Getting a 330W AC adapter would be a good idea. It should fit, have the same physical connection, but you would have to try one to see if the ID pin signal is accepted by the Precision motherboard. Probably so, but you need to verify that.

    Brilliant, thanks! I checked the heatsink - I have the CRYV5 65W heatsink, even though the processor was an i5-3340

    Flag to hear this, I was going to have an Extreme edition CPU coupled with the 980M. I just hope it won't need BIOS mods or such!

    You're welcome. The BIOS won't be unlocked, but you'll be able to do as much as before. Should be the same BIOS as any other CPU in the M6700. You should be able to overclock it fine with XTU or ThrottleStop. Installing the Extreme CPU may expose an extra overclocking menu if Dell allowed support for that in the BIOS.

    @Mr. Fox Any resources for unlocking the BIOS / getting hte BIOS to see the GPU properly by any chance?

    @Grant B Gibson If you've absolutely nothing useful to say, please don't bother commenting at all.

    3840qm would be best for the m6700, push it to the TDP max and try to maintain, there will never be an unlocked menu unless someone can hack the TPM module.

    4930mx caused a lot of VRM overheating in the m6800 and I would assume it would be likewise in the m6700 unless some major changes were made. Otherwise I would recommend the 3840qm, similar speed but less heat to contend with.

    980m is the best GPU you can upgrade to as well

    My useful tidbit of info is that overclocking is never pointless.

    Unless thermal throttling immediately kicks in...
