Understanding and using XMP

ROG Strix Z370-e / i7 8700k

Hi new member here. I am no expert in overclocking etc.
I recently bought this PC (all brand new parts) few weeks ago. For being stupid (stupid coz I just updated BIOS just for the update) , I decided to update my BIOS to 5605 from 0419. I also enabled XMP profile. MCE disabled.
Right now I have fluctuating CPU temps that I have never encountered on the previous BIOS build.
Though it is stable like I can boot to Windows..do my normal stuff (browse etc.) It's just I have fears regarding these temps. Should I be worried? Should I downgrade to previous BIOS? I also experienced 85c in normal 3D sketchup renders....

If anyone can try to help and point me on any particular setting to adjust on this latest update I would greatly appreciate it.
Furthermore, I haven't done OC this one or any delidding or any expert stuff. Thanks once again!

If not tuning manually, auto scaling rules can differ from build to build. You can either revert back to the older BIOS or tune associated voltages manually. With XMP profile enabled, look at tuning the System Agent and VCCIO voltages. How much voltage is needed depends on the memory frequency, memory and the CPU sample.

Hi and thank you Praz, (assuming the same Praz from the ancient OCZ days ?)
Just shifted to my new set up. Appreciate the post, very helpful.

Hi everyone, i have a little doubt, what should i do with the MCE? should let it in auto or deactivated, because if i only want to set my rams.......i don't know i'm a little dizzy.

Depends if you're going to overclock the CPU. If you are, select yes.

Hello,

I wanted to check the images, open them in bigger, but it wrote an error, that I do not have permissions.

Can you please allow me, so I can open them?

Thank you.

Well he had to be logged in to post his message. I've been getting this same error for months now.

Question on this XMP topic: if XMP is the first thing i've set AFTER clearing CMOS, tested ram for stability then rebooted, would there be any issues if i left XMP on and just altered all the other specs to OC the CPU and RAM?

Well, I am logged in and they do not work That is the reason, why I wrote here.

No problem at all.

Okay, thanks! I'll keep continuing to push the OC.
