I have a pretty old system: i5 3570k, 16GB DDR3 at 1333Mhz (ugh), Intel DZ77BH-55K mobo, Cooler Master Hyper 212 EVO Cooler. I'd like to upgrade in the next few years, but I rarely have time to game anymore so it's a low priority and consequently I'm pretty rusty on my tech knowledge. I did read several overclocking guides before I posted and unsuccessfully tried some similar BIOS settings used on similar rigs.After last week's Windows 10 update, I started getting micro freezes in low spec games like Overwatch (which I have set to the lowest settings outside of the 1440p resolution and 144Hz refresh rate). I upped the overclock in UEFI /BIOS to 4.30Ghz but noticed no difference. Every few minutes players would hang in the air for a few seconds and I'd be in a slightly different spot (or dead) from where I was before the lag.Looking at Task Manager, the game is nearly maxing my CPU at low setting, and when it freezes, it's hitting 100% CPU use. CPU-Z shows that I'm only running at stock 3.40GHz but Intel Virtual Bios is telling me that I'm at 4.30GHz.Is my overclock not registering in Windows anymore? Are there tweaks I could make in the BIOS settings that would give me some CPU overhead that I had on games that I've played fine for years? I could tell that performance took a hit after the Spectre and Meltdown patches, but something just feels off now.
