AMD RX 570 OC
AMD RX 570 OC
Hello everyone,
I recently acquired an RX 570 and tried pushing it to 1500mhz@1150mV and 2250mhz@935mV. The performance was great until after an hour of playing PUBG, where I encountered a green screen. Since then, it has stabilized at 1440@1140 and 2200@915 during long sessions. I’m considering going higher but prefer keeping things quiet. The temperatures were around 85°C initially, now they’re around 75°C max. However, as someone new to overclocking, especially with AMD cards, I’m curious if this could lead to issues later. I read somewhere that the worst case is a black screen or crash, but is that really the only outcome? What are the general risks of overclocking in this situation? My build specs are listed here: https://www.userbenchmark.com/UserRun/19005301
Stopped once picture issues appeared and OC lowered slightly, tried to stay calm. Personally, I didn’t notice much gain from memory changes or heat adjustments. Perhaps testing game behavior with memory modifications would help.
You're near the maximum safe level. Are you relying on WattMan?
Yes, the GPU will shut down itself and revert to default settings if your overclocking is unstable.
It's starting to feel like you're hitting the limit. Pushing a bit more might not make a difference.
Hey guys,
i'm using wattman and it's been really good so far. I also tried MSI afterburner before with my gtx 770.
But when i used afterburner with this ADM card, it affected my fan control. Sometimes the GPU fans weren't running at all, so i uninstalled it and it worked better.
like you mentioned
@Karadjgne
i managed to push it a bit more, but didn't see any real performance gains.
I also have some questions about overclocking the memory.
I use 3Dmark Firestrike to test OC settings. Does a higher Firestrike score always translate to better in-game performance? I've heard many people say overclocking memory isn't worth it, but I actually got a big boost from increasing it from the default 1750mhz@900mV to max 2250mhz@935mV.
It definitely improved my FPS for Firestrike.
Someone told me i get faster timings only by overclocking the memory and i don't want that for gaming - whatever that means, lol.
It's a personal thing and specific to the games played. If you can't tell the difference in game, then while you have a better benchmark, it doesn't mean a thing. A benchmark is a tool, it's used for 2 reasons. 1) to tell you that there's been an improvement in the running of the card and 2) pto compare your card to others who have done the same.
But your changes are working on a nanosecond scale, your monitor will have limits, the cpu will impose fps limits, resolution will impose visible detail limits, your eyesight has limits. And your perception is only so tactile. So if you can't see the changes, then there's no difference.
Think about a 60Hz monitor. Best possible visible viewing is 60fps. If the fps output from the gpu is 80 minimum, then all the OC in the world to get that to 120 minimum won't mean a thing, because you only get 60. If that OC allows for a bump in detail levels while remaining at 80, then bonus, that's tangible results, but if that 80 is already at ultra, then the power to push 120 won't do anything for you at all visibly.
And that can change with a different game and different settings.
Here’s your message rewritten with similar structure and length:
I wanted to thank you once more for the answers.
I quickly achieved a greenscreen effect by enabling "memory timing level 2" even without any load, but I think 2250@935 is quite high for this setting.
Then I lowered it again to 2200@915 and it worked perfectly.
At the same time, I slightly reduced the GPU voltage and decreased the clockspeed from 1440@1150 to 1400@1130.
Last week, I played for about two hours at a stable 120fps in temperatures between 71-74 degrees.
Even after adjusting the overclocking, I saw an FPS boost of 7 to 15 when switching to timing level 2 – really helpful!
I’m planning to push it a bit higher again to see how much I can get with memory timing level 2, but I still only reached 60fps on the monitor, so overclocking it further doesn’t seem necessary. Thanks for your advice.
@Karadjgne
My intention was to upgrade to a new monitor when moving to the 2080ti.
The memory receives the same voltage as the core is asking for. The memory voltage adjustment only restricts the card's voltage to prevent it from dropping too low and causing instability.
With those timings (2200 from 1750), I wasn't surprised that memory timing level 2 failed. In the end, you're near the limit of your memory frequency, so any timing tweaks would mean sacrificing speed. You'd need to experiment to find what actually boosts performance the most.
Did you also try level 1?
I didn't run it under identical settings
At memory I set the timing level to 1, assuming it was better; I adjusted everything else down a bit to ensure it would run, and still saw a good improvement.
Before switching to level 2, each time I increased the OC I ran Firestrike tests to check for performance drops.
But since I didn't test memory timing level 1 with the same settings, you're correct—I should probably do that today.
