I'm currently running my RX 480 at 1000 mV set in Wattman, 983 mV as measured by GPU-Z. first gpu i have bought since 7770 was released so not used to playing around with the settings in this way. You can undervolt until you start seeing artifacts/crashes, at which point increase the voltage back to the last stable voltage. i have run a few benchmarks 3dmark unigine etc. I haven't experienced any crashing or freezes as of yet. So if it seems stable, and provides you with cooler working temps leave it where it is if your happy with it Adiec I see no problem doing it. Not all graphics cards are the same, or the Gpu chips fitted to them, just like overclocking the card in Gpu speed and the memory speed also some cards do slightly better.īut it also works in reverse some cards you can get away with reducing the supplied core voltage to the gpu chip, while other Gpu chips may complain about a lack of voltage ect also crashing and freezing ect. If it has not crashed while playing a game or the system has frozen or suddenly exited out of a game you were playing and the performance of the card seems the same then I see nothing to worry about. I guess the real question is how does the 480 card play games since you lowered the core voltage of the Gpu ect in order to reduce the temperatures it was reaching. glad to know someone is running lower than i am currently and that i have a bit more room to play with. I'm currently running my RX 480 at 1000 mV set in Wattman, 983 mV as measured by GPU-Z.Īh ok thanks for that info. You can undervolt until you start seeing artifacts/crashes, at which point increase the voltage back to the last stable voltage. Will it be safe to continue to run it as it is at 1012mv rather than the stock 1163mv? would there be any risk to me trying to take the voltage lower ? Attempting to undervolt an RX 480 (and AMD cards in general) is a great idea. In fact, in some cases it can improve performance, in cases where you were previously hitting a temp/power limit. You can monitor the clocks under load to be sure that performance isn't being affected. Just increase the fan curve in MSI afterburner, undervolting isn't a great idea imo, sucks away performance.
