Got my second October 4VRM Jupiter in and on first bootup worked fine for a few hours. I updated to 1.0 to test and I noticed when I turned off SPI Auto.
I've tried the hit it with SPI 3.3 and max voltage. Let it run a few hours like that. I have had them drop when OC to high but this I can't seem to rescue.
There is it at max voltage on that one. I've swapped back to .99.1 , .99.2 and 1.0 and can't seem to get it to jump back up.
I've tried running 231 and 221 but sadly nothing helped kick that one up even.

Any other suggestions so I can put this Jupiter to a happy #

Take a screen shot of all your current die settings and save to paint, you may need to zoom out on browser to do this. Then hit reset to default. This may work, then just set everything back.
The other way would be to create more heat. Remove heatsink fan or my preferred method is to place a large durable zip lock bag over the heatsink and fan.
