Blue screens when overclocked

  1. Hello,

    I've recently purchased two machines with overclocked i7 4930Ks. Both machines will blue screen when running performance heavy software in overclocked mode. If I reset the bios to default settings (switch the overclock off), it runs like a dream (on both machines). Not a single blue screen in two weeks of heavy use.

    The blue screen errors are 'PFN LIST CORRUPT' and 'MEMORY MANAGEMENT'

    They seem to point towards memory problems, but it seems a coincidence that both machines are having the same issues, which makes me think it's unlikely to be faulty RAM. I'm wondering if it might be a power issue, but I'm no expert, and I was hoping someone might be able to point me in the right direction.

    So what is the make and model of the power supplies?

    Did you test the memory?
