It would be useful to list all brands (please specify MODEL) with and without memory temp problems with eth hashrate drops:
With drops:
Founders Edition (?)
Gigabyte EAGLE
MSI (?)
Without drops:
EVGA
Asus RTX 3080 TUF Gaming (user: BitBlitzer)
Palit Gamerock (user: 666mrga999)
I also acquired Gainward 3080 Phoenix and it drops after couple of hours, add it to drop list
