cant overclock rx 570

[Anjaney07]

So i tried overclocking my rx 570 from 1244mhz to 1400mhz core and 1750-1850mhz memory any further that i was getting gray screen i didnt changed voltage just increased the power limit to max 

i used msi afterburner

And which part is the part you "cant overclock rx570"? seems like you overclocked but not achieved the best results. Increase voltage and overclock your gpu core first. If you find your absolute maximum gpu core speeds then start overclocking memory.

I can't get any performance increases

To note, the highest core frequency I was able to get on my gigabyte rx 570 was 1380 mhz core and 1900 mhz vram. You can try incrementally increasing the voltage and trying again but take extreme caution when it comes to fiddling with voltages. Also, monitor how warm your GPU is getting.

 

What I usually do is increment the core frequency by 50 mhz at a time and run a stress test for a good 10-15 minutes with Furmark to ensure it is stable. Once it reaches a point where it does crash, I back it down by 50 mhz and run a stress test for a good hour while also monitoring the temperature. If it crashes, I'll back it down by another 50 mhz and try again. You'll probably also want to make your fan curve more aggressive, once it's stable and temps are reasonable, you can try overclocking the vram. Do not overclock the vram and core at the same time, it just creates a confusing mess figuring out what caused the crash. Get your core overclocked and stable before you start playing with the vram frequency (overclocking the vram usually doesn't result in as much of a gain anyways) 

 

I don't mess with voltages.

start by monitoring what is getting maxed out. CPU, GPU, RAM, VRAM, VRAM bandwidth, CPU temps, GPU temps.

What did you expect from an overclock 

Set the power limit to max and then see how far you can get 

An overclock won't get you more then 5% performance gain at best

I was able to get close to a 10% frame rate increase, based on heaven benchmark but it took me a long time using trial and error methods to find a stable frequency for the core and vram...

Depends on the silicon quality and the pcb quality 

It varies per user and 5% is about the average from what I have seen

That sounds about right...like I mentioned, it took a lot of trial and error to get it that high and probably in the end wasn't worth the time.

Power limit increase can only give you so much.

You'll need to play with the GPU Core voltage if you want to push more.

 

1244 MHz to 1400 MHz is pretty decent overclock, but not sure how much more you can get out by increasing the voltage.

Maybe up to ~1500  or 1600 MHz?

This is GPU overclocking, not CPU overclocking...don't expect to reach 1800 MHz, 2000 MHz or something...from 1244 MHz.

 

What did you use to test your overclock that showed no performance gain?

I tested pubg and 3d mark time spy

How much should I increase the voltage slider at a time

Are you running the tests in Windowed Mode or Borderless?

It should be on Full Screen.

 

Usually 25mV or 50mV is a good number -- 0.025V or 0.050V.
