Overclocking CPU bus

[Fpv fanboy]

Hi I'm just new to Overclocking, built my PC couple weeks ago. When I noticed the CPU bus frequency in hardware monitor, I stopped wondering what if I crank that up? I found the setting BCLK frequency in Asus BIOS and put it to 110.0000. Sure enough I got a couple hundred higher in cinebench. So now I'm left wondering what I did and was it bad? Will I toast my motherboard? Can someone explain to me the risks and so forth?

 

BTW system info,

AMD ryzen 7 5800x

AMD Radeon Rx 6800xt

Asus ROG crosshair dark hero

16gb 3600mhz Ram 

Samsung Evo 980 pro 

Asus ROG Thor 1000w psu

You raised the base frequency. That made your CPU faster because the CPU multiplies the base frequency to get up to its max frequency. Your RAM also runs off of base clock, so you overclocked your RAM a bit as well ( to 3960 to be exact) . The risk there would be your RAM not being stable at that new frequency. It's generally not "bad" unless you overdo it. If you want to overclock your CPU only, rather do it directly if yor MB supports it (I believe Ryzen master works for that but your safest option is using the BIOS)

Thanks for the reply, I'm still wondering what exactly happened that my score went up. May the overclocked Ram have resulted in the higher score? And does changing the base frequency only affect the CPU and Ram? Am I better of to adjust Ram and cpu frequency separately?

Lil update three years later lol. Your score went up because as I said previously, your CPU multiplies the base clock (the one you increased by 10%) with a certain multiplier to get its frequency. That means by raising the base clock by 10%, you're effectively raising your CPU clock by 10% since your CPU still multiplies that value by the same amount. You likely got the gains through the 10% of extra CPU frequency. But at this point, you've probably figured this out on your own, so is there even any point in writing this?
