5900x question

[dragoncurt]

Hi, all. So I am coming from the 3700x to the 5900x using the x370 gaming k7 and since using the new CPU I check some R20 scores so I know where it should be and I am getting a low (ish) number. Around 8000. It seems though that other good reviewers on YT are anywhere around 8300 and 8700. I don't know if it's a chip issue or motherboard thing. I am trying to learn how to use the PBO in the bios but seems like core 4 is crashing all the time when using CoreCycler even at negative -30 and -0

Would anyone be able to guide me on how I can do a overclock using PBO as I don't want to do an all core manual OC if it affects single core.  I do think it can do 4.4GHz or 4.5GHz at 1.35v

Thanks
Please do forgive me if I do lack the knowledge of some of the overclock settings.

The Gigabyte X370 Gaming K7 uses 6x 40A power stages for the CPU.

There is a possibility that the VRMs are not powerful enough to run a 5900X with PBO enabled.

 

I would recommend that you use something like HWInfo and monitor the CPU / Infinity Fabric / Memory frequency, and the CPU and VRM temperatures.

Monitor / log your findings with PBO disabled, and then again with PBO enabled.

 

Also, what frequency is your Memory / DRAM running at?

DRAM and IF frequency are 1:1 up until ~1900 MHz (e.g. DDR4-3800).

If you are running your memory at say... DDR4-2666 or DDR4-3000, you will notice some performance loss.
