So my i5 4670k that I got last week has started exhibiting some weird behaviour, causing me a ton of lag.
It's downclocking to around 800Mhz frequently, which causes lag doing almost anything. Moving windows around, even scrolling can end up lagging while the chip does it. In game it clocks up to full speed, but again, randomly downclocks occasionally to 800Mhz to around 1.6Ghz.
I've reset my BIOS to stock settings, but the issue persists. Temperatures are low (sub 50 degrees at load on stock, sub 70 overclocked) and there aren't any PSU issues (EVGA 650W).
Any ideas what's going on here and how I might fix it?
