With this, SMRAPID had the same error again, showing 800, but it did not disable RAPID, though, after a while, my pc crashed with that 'you've messed up your oc' kind of a screen. I had RAPID active by:ġ- Loading optimal default BIOS settings. I assume it is related to gtoph's sugestion, though I don't know how to do it. Once I overclocked the CPU running Asus AI Suit 4-Way Optimization, the 'problem' came back, with System Info, BIOS and SMagician showing 800 or 801, and obviously, RAPID won't run. I noticed that on default values, System Info, BIOS and Samsung Magician, all showed 3.5Ghz, hence, I could run RAPID. I'm running a 4770k on a Maximus VI Formula and for what I understand, the BIOS update worked because it resets the BIOS's parameters. I was trying this today, since 840 Pro's are now supported, and I noticed I have this exact problem.
