Ethereum update: 4 RX 480s crash continuously with Glacier 1000W PSU. Am I missing something big?
Hi friends! I have
Phenom II X4 965,
Rosewill Glacier 1000W PSU,
3 MSI ARMOR RX 480 4GB,
1 XFX RX 480 8GB,
Recently I’ve been mining with these three MSI cards and everything has been smooth, using latest drivers set to Compute, and no bios mod for any cards. I just set a fancurve on Afterburner and mine ETH on Nicehash. After installing a new card (XFX) newest drivers for it and everything, Nicehash can mine for a few minutes only if I apply an undervolt of -25 mV to each card. However, it always crashes, and no matter what overclocking app I use, it wont let me mess with the core clocks or memory timings. More severe undervolts (-50mV per card) will also cause it to crash quite soon. Usually the screen goes black, I hear a ‘click’ sound from somewhere and the system stops running. Are there any drivers that limit power usage, would flashing the bios help (i’m nervous as they are not my cards) and is there a reason that a 1000W PSU would ever not be able to support all these cards?
Thank you so much for reading. Cheers
