crash without oc , default bios/mem/clock

i will try afterburner but is there any on linux?

Any idea how to  test gpus? I have few 390x but one of them mining ok but crash sometimes 1-2 times per day sometimes not...  dual mining... temps about 85 degree (no matter solo per mobo or with riser and 5 gpu rig)

i cant send warranty because it looks fine... not sure how to check or proov its smth wrong with that card..

Hey,

Claymore, great miner I have one small issue... sometimes (not sure why and when) 1 card show error with info about stopping watchdog gpu 5 (and trying to reboot.bash or restart miner) but this is weird because there is only 1 card (no matter solo or multigpu) , PSU checked, temp 85-88 degree , fan 90%... i wish to RMA warranty this gpu but ... its working sometimes 40hours non reboot... sometimes it reboots 5 times a day.... any idea how to fix it? or maybe how to stress test if its broken?

p.s. 4 gb ram is ok for 6 gpu? linux

Tom
