    After installing the new ("overclocked") vbios began to overheat the PCH.

    Installing a copper heatsink on the PCH does not help, the temperature rises to 90 degrees Celsius.

    Dell's support service can not help and refuses to replace the motherboard.

    Added declocked vbios. Its installation solve the problem fully.
    (Yes i'm flash it :))
    Tested on 6820HK system

    Same here. Leads to heavy throttling in ME Andromeda when temp hits 80°... No freezes but massive FPS drop until PCH cools off a bit. CPU stuck at 800MHz.

    Had no problem whatsoever before. :( Wish I could go back to previous VBIOS.

    This happens on the BIOS version below 1.0.8. At 1.0.9. and above, there are microfreezes
    P.S. I lowered the CPU temperature to 65 degrees, but this does not help ...

    Right, I'm with 1.0.8.
    1.0.12 gives me BSODs...
    How did you manage ? Did you lower settings ? I play @1440p, on ultra and it's great except for fps drops when temps get too high.

    I hit 65W (and almost 80°) with CPU (OC@4GHz) and 205W for GPU (but it stays at 72-73°, so not too bad). I saw that CPU usage is pretty intense in ME Andromeda (I'm above 85-90% the whole time).

    ME:A is the first game I have a problem with. I played 50 hours MGS V @ max settings 1440p and it runs like a charm, with great temps.

    so you are saying just by placing a fujipoly thermal pad on top of the PCH reduced the temperature significantly? u dont need some kind of metal heatsink on top of the thermal pad? also, when u move the laptop around, will the thermal pad fall off?

    What bios are you running? I've got an aw 17 and my PCH temps hover at 93-94 while playing ow and I'm getting no throttling at all.
