Hello

Single bit errors are memory errors. They may be related to the memory on the PERC that is used as cache or system memory. The slot that is reporting the correctable errors should be mentioned in the error. If it is reported against the PERC then the controller should be replaced. If it is reported against a system module then you should move the module around to determine if it is a slot, module, or memory controller issue.

Data corruption can occur if the PERC battery is not functional. Data corruption can also occur with faulty memory. Single-bit  errors are correctable, but it is a sign of problems. The warning is letting you know that a module is showing signs of failure. If a multi-bit or uncorrectable error occurs the system will halt. This could cause data loss/corruption.

False errors can be reported during an improper shutdown. If there were issues during the restart then I suggest choosing the option to continue, let the system updates complete, and then perform another restart to see if the issues persist.

Thanks

Update the latest BIOS firmware and check. Probably it will fix your issue.
