Amiga Test Kit v1.6 says my A1200MB rev 2B has timing issues

[klx300r]

system is stable though some times after many hours of use system hangs but after a full reboot works ok..wondering if its ram related or MB needs timing fixes...so far checked 2 ram cards and both gave same results below though one ram card had errors:

'CIAA TOD expect 16 ticks: 10149055: FAIL''CIAA TOD IRQ Failure'

Chances are that your A1200 motherboard has a faulty CIA chip... more specifically, the CIA-A chip, U7.

"What the hell am I gonna do, now that my 8520s are blown..."

so how to confirm if system working ok other than as noted above...
