I just bought my pc 1 week ago and checked my Event Viewer. I kept seeing this warning:

A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Bus/Interconnect Error
Processor APIC ID: 0

The details view of this entry contains further information

Should I be concerned? I'd appreciate if you could help me on this.

Specs:

Ryzen 5 5600

B550M K

Team Group Elite + 2 x 8GB

Radeon RX 6600

Did you try at least testmem software to figure our how ram working?
Whea - it is hardware error, mostly linked to CPU and mainboard, in my practice when my r5 1600 start to die, this error it appear in logs after system hangs, it can play games for it's final hour, but will hang in windows. Last hang happen when I plug network cable, after that - only work in bios settings, mainboard from that build still alive.
My friend have same error on r5600 with b450 board which died, same, it can hang in system on video streaming for example but not in games or on hard load.
You have b550, high voltages for CPU's on boost fixed somewhat on that boards, on older mainboards you need to UV any CPU. I don't think it's CPU itself in your case. Good luck.

I did run memtest86 and all rams passed. I will try and UV the CPU. Prolly disable PBO and CPB and see what happens.

Also check for your video card CPU seats/contacts - clean and sit well in places, power cables plug in fully.

So what worked for me is I UV'd my ram settings in bios. Set the system memory Multiplier  from 32 to 31.33 and FCLK Frequency to half of it which is 1567MHz. Reboot and did not see the errors no more. So my question now is my memory faulty then?

In some cases memory can pass tests in overclock mode but can give some glitches in Some applications/games, but not serious errors like whea. That strange. It's your default memory clock 3200 ? what voltages? XMP seems not used if you able to change frequency. (Last thing I overclock it's core2duo 4500, previous it's celeron 333) So I didn't use overclock for a long time. Try disable xmp, check default SPD for you memory (hwinfo/cpu-z) and set it, when test.
You can also UV the CPU after you figure out about memory, if it's 1.45 on boost you can try to set offset -0.100, all my cpu's can handle even more, sure your CPU can handle it too.
