Hello there, i have here 2 GTX970 cards, a Palit and a Asus. both with same error - no picture and on laboratory power supply at 12V - it draws only round 600mA instead of 900-1000mA for a working card.

all Voltages present, bios chip also changed. Cards wer detected as secondary card in DeviceManager in Windows but when installing drivers - card was not anymore detected in windows. in Mats as secondary card - we cant test this card, dram access erros in endless loop.

what can her happended?

You can check mats by connecting the second card. Look for information.
