Hi Guys,
I had tried to find an answer to this via Google and elsewhere, but no luck so far. I have my i5 4670k Oc'd to 4.2Ghz @ 1.16 vcore. I have RAM set up via XMP and only other thing I changed was Uncore Frequency from 3.4 Gig to 3.6. The system is stable, have tested with OCCT for 2 hours, Aida for 4 hours, Prime95 for 10 hours and have encoded video via Handbrake overnight. Temperatures seldom rise above 60 degrees.
What I am finding, is that even when idle, the CPU clock can peak at ... wait for it ... 300 million Hz. The Northbridge clock has peaked at over 300 million. Now, the temperatures are fine so I'm thinking it's a momentary spike. I just don't know what's causing it.
At first, I thought it may be OCCT reading wrong but it shows the same in Aida.
Any ideas on how to resolve?
Here's a link to some Dropbox screenshots...

** Edit to add ... the system does this even with BIOS defaults, i.e. stock. **
