Does it make any difference how I get to the oc speed I want. Is overclocking the cpu vs increasing the bckl any different ? I seem to remember that it's better to get the overclock by raising the cpu speed.

Yaa, it makes a difference when you get oc speed you want. Over clock by raising the cpu speed.

Hey D.  My rule of thumb is to get the OC via the CPU multiplier (assuming your CPU is unlocked of course) and then use BCLK only if it's necessary to fine tune it.  Once you start upping the BCLK you're putting stress on other components and subsystems as well.

I want to say no to different results because one is just raising the multiple based on the BCLK and the other is changing a BCLK with a lower multi. Same numbers, different way of doing it. However changing the BLK does affect some subsystems which is why you can't do 150 or 200. Soooo.. IDK.

Interesting read,.. depends on the motherboard for how much BCLK is already pre-overclocked, adjusted past spec 100.0,.. when using Auto, XMP and MCE settings.  https://www.gamersne...bclk-comparison
