#Asus rx 480 gpu tweak mining undervolt manual#
I haven't experienced those sorts of problems on Polaris cards using dynamic frequency and manual voltage though. This article was definitely using/relying on auto frequency, and there's definitely some weird stuff going on with the AVFS thinking it can go.higher frequency than default with.less voltage just because it got tricked into thinking it could apply more power.but it wasn't. Then you look at the frequency charts and undervolting by 25mV with a max power limit gained them 125MHz core. Still odd that a 1V clamp wasn't being treated properly without the power limit increase. : Ok, it looks like in that review, the Balanced/Auto setting was already applying ~1.025V anyway, so if you call 25mV an "undervolt". I did skim back over the article, but don't have enough time to fully analyze the issues they had (it would seem they're still allowing something to behave "automatically"). AMD has such voltage for majority of their chip because majority of their chip need that much voltage for stable operation. it's like putting their majority of chip at disadvantage just because of this small percentage chip that cannot operate at much lower voltage. but because of this tiny percentage cannot operate at much lower voltage AMD decided to increase the voltage for the majority of their chip which else are doing just fine with much lower voltage.
only very very small percentage of chip unable to do it. i see this wrong assumption by majority of people that almost all AMD chip can be undervolt successfully. i still remember when people raging about XFX RX480 (i don't remember which one) able to hit 1475mhz on jayz videos (hand picked by XFX of course) and they said this specific model probably guaranteed to hit at least 1450mhz, but there are people with the same exact model can't even get passed 1400mhz. take this for example: how many RX480 able to hit 1500Mhz and use that clock on 24/7 basis? then compare it to RX580.
