    Hi all

    Please some advise. I have the Y700-15ACZ (FX-8800P, M385X 4GB). While gaming, the GPU clocks go down to 300MHZ from time to time (about every 2-3 seconds). I don't see why - the TDP remains the same according to HWInfo and the temps are quite ok.

    I even used MSI Afterburner and downclocked the GPU to 0.5GHZ/1GHZ (core/memory) which is a lot lower and it still happens (and TDP/temps are much lower too).

    Any clue?

    I've tried several drivers from Lenovo and from AMD and nothing helps. The performance is actually quite ok, except these jumps in clocks..

    Thanks

    Hmm... could it be because it is working in a dual gpu setup?

    Thought about it, but I don't think so.. the iGPU load is quite low and so are the clocks. Doesn't seem to be impacted too much by running games

    Anyway, it seems like downgrading the bios helped a bit
