I have the same continual reset issue, machine online since the boards release date & untill now its been ok.
Bios 1504, memory has been changed & single alternate module population has been tried.
Reseated cpu, changed heatsinks (as below & intel stock), different thermal pastes AS5 & MX2 & 3, switched off temperature monitoring within power management, temperatures are cpu 29, nb & chipset 45/47. Complete rebuild in case of short circuit with chassis. All within parameters. Any ideas?
