755 G5's in stock and not a single one works. out of the box have blue screen and performance issues with my companies image and with the OEM image (install it is shipped with). All three display repeatedly in the event viewer "WHEA-Logger eventid: 19 Cache Hierarchy Error".
I have done a considerable amount of troubleshooting and research regarding this. The best I can find is on gamer forums where voltage issues or BIOS versions cause this. I have not been able to clear this out and wondering if anyone else has had a similar issue.
A corrected hardware error has occurred.
Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Cache Hierarchy Error
Processor APIC ID: 4

You're not alone.
I have a Elitebook 735G5 with Ryzen 7 pro 2700u with same problem.
Actually the problem happened since HP release BIOS update 01.03.01.
BIOS version from 01.03.01 to the latest 01.06.01 all have same bug, they didn't fix this.
If you don't want to see this error information, you can downgrade BIOS to 01.00.03.
01.00.04 has a nvme ssd running on pcie 3.0 x1 bug.
Once again, I hope HP fix this bug ASAP!

Thanks for the input Putins. Rolling back BIOS is not an option due to some of the issues newer versions address.
I will keep opening cases with HP, maybe they will fix it one day. I have had to go with a different build for laptops since this caused so many issues for us.

McChingus, as I looking into the changlog of BIOS updates, didn't find anything really impact daily use if you choose rolling back to old version, and I don't have wierd issues with 01.00.03 BIOS
So I think it's a option at leaset for people who doesn't want to see the error event crazy increasing (about 3 error events per minute)
