tattude69if the leds are similar to the classifiedThose 5 LED's are voltage indicator lights that can help you diagnose voltage problems with your video card. With the gpu fans facing towards you and the power connectors facing up, the LEDs are, from left to right:GPU - This indicates if voltage to the video card's GPU is goodMEM - This indicates if voltage to the video card's memory is goodPLL - This indicates if the voltage for auxillary components such as fans, LEDs, etc. is good3.3V - This indicates if the voltage supplied from the motherboard via PCIe slot is good12V - This indicates if the voltage from the 12v input from the power supply is good
Bali2010Yes one of these leds is lightning up when my gpu is frozen. Also the fans turned to 100%. And i dont know what does it mean.
TiN_EEIf I remember right:D3905 indicates MCU firmware status. Normal operation should be never on.D3909 shows memory VRM status. Might be issue with memory power/VRM.
Bali2010Because if i play Black Desert Online, after 20 minutes this led lighted up, fan goes to 100%, and got a black screen...
