Zotac GTX 1080 8GB card starts normally without error in the device manager, under load Furmark artifacts and freezes the computer and show error 43 in device manager. Mats in the automatic test shows two damaged banks, then only one. Sometimes it does not start after 30 seconds, the monitor wakes up. What you think, damaged memory or core??
