    swapping out chipsets from a mobo

    So,

    Someone is telling me they got an ASUS intel chipset mobo, then had someone customize it so that it took on an AMD 8 core. Is that even possible? I thought the CPU chipset was formed INTO the motherboard and not like an interchangeable part? Something doesn't jive.

    This is the mobo they say they got is this:

    But he said they took out the intel chipset and replaced it to use this CPU:

    MOBO: GA-Z68X-UD3H-B3
    CPU: i7-2700K @3.5 ghz
    RAM: G.SKILL Ripjaws X 32GB (4 x 8GB)
    CPU COOLING:Corsair Hydro H80i
    VIDEO: MSI TF 2GD5/OC GeForce GTX 760 OC N760 in SLI
    HDD: Intel 320-160GB SSD
    HDD: Samsung 840 250GB SSD
    MEDIA: Plextor Dual DVD
    PSU: CORSAIR HX750W
    CASE: Antec Twelve Hundred V3 Full Tower
    OS: WIN 7
    10 x64 Home Premium
    Monitor: AOC ,32" curved 1440p

    No. This is not happening, for many reasons, but not the least of which is the fact that the two companies don't use compatible technologies between CPU and chipset, and don't use similar pin counts.

    You would have to replace the CPU socket and the chipset, which requires reconnecting roughly 2011 traces to a new cpu socket, which only has 942 pins. Not to mention that intel uses a PCH "unified" 1-chip solution, while AMD is still using Northbridge/Southbridge 2-chip solutions for chipsets.

    Admittedly, these days a chipset is nothing more than a way for peripherals to talk to the CPU since the memory controller and the primary PCIe controller were moved on-die. So running from the chipset is SATA, NIC, USB, and sound. But the chipset is just as unique as the CPU, and is designed to work in concert with a specific CPU series. You can't plug an AMD CPU into an Intel Chipset or vice versa. Hell, you can't even plug an old AMD CPU into a new AMD chipset. Won't work.

    I'm calling bunk on this. The idea of not just changing a pin-compatible chipset (say like when Intel did minor revisions to a given chipset, allowing motherboard manufacturers to re-use existing designs), but replacing it with a competitors chipset(s) and CPU socket without destroying the board is not possible.



    Quick stats on the two CPU's and chipsets involved here.
    Code:
    CPU
    ------------------------------
    BRAND		Intel	AMD
    SOCKET  	LGA2011	AM3+
    SocKET TYPE	LGA	PGA
    PIN COUNT	2011	942
    PIN LOCATION	SOCKET	CPU
    
    
    CHIPSET:
    ------------------------------
    BRAND		Intel	AMD
    CHIPSET		X79	990FX 
    TYPE		PCH	NORTH/SOUTH BRIDGE DESIGN
    SocKET TYPE	mBGA	FCBGA
    PIN COUNT	676	692
    SOUTHBRIDGE	-	SB950
    SB SOCKET	-	*
    SB PIN CT.	- 	*
    
    * I was unable to easily track down the pin count and packaging style of the SB950 portion of AMD's chipset.

    This is the equivalent to someone telling you they bought an orange and then stuffed a pineapple into it.
    There is the theory of the moebius. A twist in the fabric of space where time becomes a loop.
