Thanks for the tips.
Had worked out that you can't update the individual prpclient.ini files via updating the master_prpclient.ini file while it's running. Had tried changing the stopasapoption parameter to 6 in the 4 individual prpclient.ini files but it didn't work for some reason and downloaded new tasks. I must have done something wrong or it was just that machine mucking up again, it's turned off now as I memtested the memory and it's faulty.
New memory should arrive this week, a new brand for me, Kingston and the model is HyperX Savage. Hope it's Savage enough to cope with BOINC better than the faulty G.Skill. The exact model Kingston is on motherboard's memory QVL, so hopefully it will be able to run at its rated speed. Funny thing is the keyboard on the dual socket box has just started playing up, @/2, w, s and x keys have stopped working. It's a Keytronic Lifetime model, but obviously its lifetime is more limited than mine.
Noticed you've added the team to your dingo7 machine. With that and my 16 instances now returning the correct tasks we've passed Aggie The Pew team for 2nd spot.
I vaguely remember that Aggie the Pew was the name of a Primegrid contributor's pet rat, haha.
