![]() ![]() ![]() This could be the case when it lowers the clock below 1411 mhz, even though you are not drawing 175 Watt (power limit) yet. It is possible that the card is reaching some internal temp or voltage limit, but NOT your power limit. ![]() Trying these, (or all three) will likely have you running at 1411 mhz more (or most) of the time. Set a higher power limit (up to 110% for nvidia cards, not sure how AMD cards handle this). Core Clocks Boost: 1740MHz Power Consumption 240W Power Connectors 8-pin. Set a higher voltage (not without risk, although it should be limited by the GPU BIOS within safe margins) Reduce temperatures (run your fan faster on a custom fan curve using MSI afterburner) So if you want to hit a higher (boost) clock you have to: There is an algorithm inside the card that will boost the core clock of the card, until you reach one of the set limits (at least on Nvidia GPU Boost, I assume AMD works similarly). īasically there are 3 things that govern the clock speed: It should hit the base clock 100% of the time, but not the boost clock. So it doesnt advertise that it will hit that boost clock 100% of the time. If I look on the Sapphire website, it says the boost clock is UP TO 1411 Mhz. I looked gpu-z and saw that my power board limit is 175W, so this is suppose to be normal? why they put something like this to prevent you from getting max value out of your GPU?Īnd another note that some games even when they put 100% load on GPU they don't draw the max power(175W) so i get stable 1411 clock !!Īlso does increasing power limit in afterburner solve this problem? if it does, does it also increase temps? I noticed whenever i hit more then 170W power consumption(or close to less then 60fps in games) the core clock would come down fluctuating between 1411 and around 1380 and i can't get a stable 1411 clock so i know i'm loosing frames Temps are around 75 at max load but there is one problem Having said that, the Radeon RX 570 deserves special mention, as we managed to get a 12 per cent performance boost in Fire Strike after overclocking, which is quite impressive for a card of its class.My last card was rx470 nitro+ and yesterday i bought a used rx 580 4gb nitro+ and everything looks fine The proportionate increase was similar in Fire Strike Extreme as well, so there’s still a tiny bit of performance to squeeze out of these cards with overclocking. Ultimately, we achieved between 5 and 6 per cent increase in Fire Strike for the GeForce GTX 1060 and Radeon RX 580 respectively. What’s more, the Radeon RX 570 took quite well to overclocking as well, so AMD clearly has made some much-appreciated tweaks in its second-generation Polaris architecture. The Radeon RX 580 overclocked surprisingly well, and this was a nice change considering the lackluster results we had with the Radeon RX 480. We used MSI’s Afterburner utility to overclock the cards, and here’s a table summarizing the clock speeds we managed to achieve. It also posted a total system power consumption figure of 300 watts, higher than the Radeon RX 480 as well.Īs it turns out, these results are actually testament to how efficient NVIDIA’s Pascal architecture is as it managed to run cooler and consume less power while offering similar performance. The Radeon RX 580 ran 5☌ hotter than the GeForce GTX 1060, which is probably unsurprising given its much higher power draw and TDP (the NVIDIA card has just a 120 watt TDP compared to the Radeon RX 580’s 155 watts). Since both the cards we’re reviewing today use the same MSI cooler, their temperature figures should be quite comparable.
