I've got some years experience with BOINC but quite new to primeGrid.
Recently I'm getting a serial of invalid results with my 2019 iMac (i9-9900k, RX pro 580), but similar errors does not happen to my two other PCs (i7 CPUs with Windows).
For GPU jobs:
- AP 27: OK.
- GFN 15, 16, 17, 18: seems all OK
- GFN 19, 20, 22, Extreme: consistently invalid.
For CPU jobs:
- 321, ESP, MEGA, PPS, SGS: seems all OK
- CUL, WOO, PSP, SOB: chances of error/invalid results.
For the time being I suspended receiving tasks for these risky projects on the iMac.
Could anyone give me some guide on troubleshooting?
