I find the description on the V3-571G motherboard is : "ACER MAIN BD N14PGE 4GB QC USB3 0"

My questions are:

1) What does the QC represent?
2) Is this an HM77 chipset board?
3) Does this board support Turbo Boost for an i7-3632QM processor?

Thanks in advance.

    Hi,
    1. Don't know.
    2. Yes, it has HM77 chipset.
    3. Yes, it supports Turbo Boost version 2.0

    Thank you for info. 

    Maybe someone else will be able to answer the 1)

    As to aliexpress seller member info as being completely reliable, I've seen descriptions of this board as showing HM65 hub  chipset, AH55, and both Rev 1.0 and Rev 2.0, leaving one to wonder if there's multiple configurations of the board part number, unintentional misinformation, or typographic errors in the description.

    A study of the Intel chipset specification and datasheets show the HM6- and HM7- being roughly compatible, at least as far as what the V3 offers in USB ports and needs as far as SATA/etc capabilities.  The main distinction between HM6- and HM7- chipset is the transistor sizing (nm) and power requirements, the HM7- being smaller size die technology and lower power requirement.

    I'm not sure but QC could be for Quad Core:
    CPU.I7-3610QM.2.3G/1600/45W
    CPU.I7-3610QM.2.3G/1600/45W
    CPU.I7-3632QM.2.2G/1600/35W
    CPU.i7-3630QM 2.4G/1600/45W

    laurent_14laurent_14 , after studying the HM77 processor compatibility list, I believe you are correct.

    http://www.cpu-upgrade.com/mb-Intel_(chipsets)/HM77_Express.html

    I look down the list (HM77) until I find

    i7-3632QM - AW8063801152800

    and then under that I find these two entries:


    i7-3632QM, 2.2 GHz, L3 6 MB, HD 4000 GPU, Quad-core  
    i7-3632QM, 2.2 GHz, L3 6 MB, HD 4000 GPU, Quad-core, Turbo 3.2 GHz  


    .. so the last one is Quad Core, Turbo Boost...

    and here is a photo of a full house V3.. I don't know if there's a "last 4 digits model number", I could get no more info on this particular laptop.

    I am ordering the NB.M7D11.001 motherboard, Rev 2.0, which has the HM77 (SL8JC ) I/O hub chipset, the GT-730M  (N14P-GE) Nvidia graphics processor with 4GM graphics DRAM (8 chips total, 4 each side of board), and board revision Rev 2.0.

    I have located a set of FHD hinges, FHD display top plastic, FHD LCD from laptopscreens, and a 30-pin LCD cable.

    It would have been much easier if I could find the laptop pictured, but it appears to be non-existent in the USA... only foreign, and rare, even then.

    Yeah, I "just have a hankerin' " for this particular machine.

    Thanks again, all, for information... I am very appreciative for your help(s)

    Note on my last post, just above... the pictured laptop label shows only 2GB graphics ram... therefore, that would be the NB.M6A11.001 motherboard, and not the NB.M7D11.001 board I desire.  The difference is 2GB additional memory on the NB.M7D11.001. 

    A close look at the DRAM chips on these boards shows, in the chip number, either 2G or 4G.  That would be 2G x 1 bit or 4G x 1 bit, and there are eight (8) chips to make up the entire byte.  The 2G chip is typically Hynix H5TQ2G63BFR 2Gx1 bit.

    The best way to find out the specs of your computer is to do the following:
    1. To find out your laptops or for that matter any computers specs of its CPU, Caches, Mainboard, memory, SPD and Graphics, specs is to download CPU-Z at: https://www.cpuid.com/softwares/cpu-z-android.html
    2. To find out your BIOS specs and type, get the 'dxdia' in 'Run' and it will tell you the exact name and version of your BIOS
    3. As you can see in most adds you get 'NOKOTION NBM7D11001 NB.M7D11.001 For Acer aspire V3-571 V3-571G Laptop Motherboard Q5WV1 LA-7912P DDR3 GT730M graphics' and the V3-571G has the 'Q5WV1' and 'LA-7912P' as its common denominator.
    To find out your mainboard model, you have to open the case and take the keyboard bezel and touchpad bezel off and the model number is at the 'left top mid corner' of the mainboard and it reads something like this: 
    WVH LA-7912P (which is the Mainboard Model #)
    REV: 1.0 
    2012 – 03 - 22 (date of manufacture)
    4. For the exact prefixes of the mainboard, there are 3 stickers under the RAM modules where you will have e.g. 
    MB - NBRZP with 17 number after these letters 
    then CQPCBB: 220
    Q5WV1 L05 or something similar.   
    5. The chipset can be obtained with CPU-Z
    6. Turbo boost comes on automatically on these mainboards and they don't have a setting in the BIOS, that is how 'turbo boost' works, as the CPU only comes into boost when certain software application require them. 

    The most important is to have the right model number. This is all simple, hope its answered your questions, cheers
