Fixed...? Gigabyte GPU Constant white power LED

[iavoe]

I've bought a 2nd hand RTX 2070 to replace my GTX 1070, everything was working prefectly but I've got a briiiiight white power LED on the RTX 2070.

 

The card is a Gigabyte Windforce RTX 2070 8g, but not important as the problem may apply to all Gigabyte/Aorus cards.

I'm listing all attempts I've tried and failed so you may get away with these steps:

 

At1: use an eraser to clean up potential dust build ups on PCIE pins (gentally) - fail

At2: download Gigabyte lighting software to find the LED switch - fail

At3: download Gigabyte AORUS ENginE, AORUS eXTrEMe and find the LED switch - fail

At4: download Nvidia LED Visualize - fail

At5: re flash a BIOS - fail but bios may be updated

At6: re install Nvidia driver - skipped as I don't think thats related

At7: unplug and plug power pins on graphics card - tried 6 times, all failed

At8: move the GPU to a different slot - fail but RGB text has lighten up

 

At9: plug PCIE power cable to a different slot on power supply (having a seasonic M12II, fully modular) - succeeded, for a day, led light up again at night

At10: the next day, problem disappeared again... Tried to wiggle the power cable around while system is on - no issue

At11: checked HWiNFO, there's the screenshot when LED are off:

At12: checked people discusses about M12II EVO, no undervolt issues, but it doesn't not support C6, C7 power states, which shouldn't cause my problem

 

AT13: changed power supply cable back to original slot, still can't reproduce the issue, I'll try a not full plugged in HDMI cable later

how does that even fixed my problem? Weird huh?

im assuming it's the LED at the PCIE power connector to tell you it's connected correctly or not

 

though... idk how that would make it go away

My thought as well.

Only thing I could think of is the modular socket on the PSU side is faulty.

Moving it to another socket, that's NOT faulty, and everything works.

Maybe that slot was used for a long time to power my gtx 970, 1070 and now 2070. So it somehow glitched

uhhh the light it's back, I'll try fix it tomorrow...

1: open HWMonitor and look for voltages, it might be wrong - done for the LED off situation

2: windows10 pcie power plan - it is full power for PCIE slots

3: switch a power cable, it might be old - tried to wiggle this cable around but LED won't light up

 

This is really strange because I never had an issue with power on my GTX 1070, and it really doesn't look like the power supply is not right

Check later: RTX 2070 instantaneous boot voltage/wattage and R5 2600 1.37v OC wattage

I've switched the powercable on powersupply back, I'm still unable to recreate the problem, I guess it was only a glitch...

I've switched powersupply-end cable slot back, and I still didn't reproduce the issue, the ladt try could be about the hdmi cable was not fully plugged in
