They still kinda do. It's not the bus, but there is one clock called BCLK (base clock) now and almost everything is derived from it. It's not adjustable on cheaper boards, but with a good board you can absolutely do the same adjustment :)
- seabrookmx 8y agoYeah I have an older box running an i7-920 which is overclocked from 2.6 to 3.6ghz with the base clock. Sandy Bridge and newer get extremely unstable when you toy with the base clock more than a few MHz though. You're basically stuck shelling out an extra few bucks for a "K" chip if you want to overclock on Intel now.
- floatboth 8y agoSkylake and newer have fixed this, they decoupled PCIe and stuff from BCLK. On Skylake you can actually do non-K (I ran a 6400 at up to 4.7GHz): https://overclocking.guide/category/intel-oc-guides/skylake-non-k-oc/ https://overclocking.guide/category/intel-oc-guides/skylake-... Of course on Kaby and later they closed the loophole...
