Question Does Asus OC AMD CPUs out of the box in the BIOS ?

[Sohaib]

Hi folks,

I built a system a couple weeks ago using a Ryzen 9800X3D on an Asus Strix x870E-E motherboard. Coming from a Ryzen 3900X its a HUGE improvement in FPS even when playing at 4K with a 7900 XTX GPU.

I saw some videos (gamersnexus & hardwareunboxed) to be exact about how asus loves to OC CPUs out of the box (looking at you 14900k). I don't like running my CPU out of spec, i mostly bought the board for it's great USB 3 Gen 2 support and the MSI MPG X870E Carbon was sold out which was my first priority.
I haven't used an Asus motherboard in over a decade so wondering if there is some setting in my UEFI which i must disable?

I did go through some of the settings in the BIOS but nothing specific caught my eye that could be a red flag.
I just enabled AMD EXPO and disabled the integrated GPU and that's how i am running my PC so far.

It depends on the board, but the majority of them have PBO/PBO2 (Precision Boost Overdrive) which is basically the factory overclock setting) disabled by default. You can check the advanced CPU tweaker settings and look for the PBO/2 setting. If it's on auto or enabled, then disable it if you have thermal problems with it enabled or simply do not wish to have it enabled. If it is already disabled, there is nothing else you need to do and no overclocking is going to occur unless you do so using the BIOS configuration settings or Ryzen master.

I checked BIOS and manually disabled PBO2, it was on Auto.
I ran CPU-Z benchmark and spitted out 828 single core and 8760 multicore result which is a bit higher then normal so i guess Asus board is doing some tweaking in the background by default. I ran 3 tests average and all gave me over 800 on single core.

My idle temps at desktop hovers in 40s to 50s with an Arctic Liquid Freezer II 240 AIO and thermal grizzly kryonaut paste spread thoroughly with spatula. I also used thermalright AMD secure frame.
But these are winters, my room ambient currently is 19C. I live in south east asia where summers are like 9 months long where outside temps can easily reach upto 48C and with 24/7 AC my room hardly reach 26-27C most, primary reason i don't want any overclock.
