XGD Hardware ovrSR Errors Logged but System Functioning Well due to In Some Scans Gradient + ECC Compensation will Exceed Slew-Rate Limit and DSP Firmware will Detect and Report a Warning.
Symptom
XGD Hardware ovrSR Errors Logged but System Functioning Well See Long Description We see these errors being logged during scanning and also during Gradient Hammer diagnostic but there is no apparent effect on system operation. The system seems to be running well. What do these errors mean and should we troubleshoot the system because of them?
