Hi there.

I have a little problem. Although this is the first 4770K / 4790K CPU, I got it stable under water cooling at 5 GHz, but anything higher clock is very unstable, particularly at low input voltage. I can increase VCore up to the stop does nothing.

Example: XTU @ 5 GHz - 4790K:

LLC level changes doing nothing, just increase the input voltage, maximum everything is about 5 GHz only superpi stable.

Does anyone here have an idea what I could try?
