NI PCIe-8431/16 bit-fails on some computers

Sir's

In our production testing of gyro modules with RS422 I/O we have been using PCIe-8431/16 for many years (12-14 test stations). Earlier this year we installed a new computer in one test-station and we started to detect a lot of communication-errors (CRC calculated from received data different from CRC received as part of data-packet).  It took us a while with testing and searching to determine that the computer itself is generating the issue, a problem we only have detected on two new computers.  Any explanations, solutions or similar experience?  

 

Problem computer: Dell Precision 3660, win10, Core i7-13700 24 cores, 32Gb ram, NI-Serial r19.0

 

Example of OK computer: HP Z240, win10, Core i7-7700 8 cores, 32Gb ram, Ni-Serial r19.0
