Sapphire Nitro + RX 570 Overclocking!!

[JaSoN_cRuZe]

My config has Nitro+ RX 570,

I have currently OC'ed my card to 1500Mhz Core and 2000Mhz Memory,
using MSI AB @ +100mv.

Fire strike high graphics score is 15349 using above settings.

My question is can it go beyond 1500Mhz in Core by unlocking the voltage further, i can use trixx to get a max of +200mv?

Can my GPU handle the load and is it feasible to go beyond.

I have hynix memory, increasing the memory clock( >2000Mhz) causes stutters during gaming so it is left untouched, providing more volts will allow memory OC even further or it only helps on Core clock??

Every card is different so it all depends upon luck. it might or might not go beyond but you can find the maximum clock. Overclocking is hit and trial so i would suggest that, if your current overclock is stable and you are not having any issues (i.e temps, artifacts etc.) then make it base point and go by adding +25 mhz to core and memory. Run benchmarks and if stable add 25 more, if unstable try adding +5mv and repeat this process until you start running into shutdowns, artifacts, freezes etc. the last stable clock will be the maximum.

Actually @1500Mhz in between games i tend to have black screen with no audio, also @1500Mhz while bench-marking i can see fluctuations in FPS hitting minimum of 2 fps in ACO, figured out it was the GPUOC that's causing it, so finally reduced core to 1450Mhz and left the memory @2000Mhz also reducing the volts in MSI AB to +10mv.

Now its more smooth and i'm getting 15500+ in firestrike.
The factory setting was 1340 and 1750 for core and memory clocks respectively.
i think this is the max i can push.

So now i'm not experiencing black screen or bad fps drops and actually increased performance..
Also verified using ACO in game benchmark went from 6600+ to 6750+ using custom settings.
Thanks

Well this is great if everything is fine. May be you can push a lil further to 1475 on core. Try reducing voltage more and check if system is stable. It will reduce your load temps as well

This was the scenario after overclocking anyways thanks, i think this is the most stable.

Hi i have same GPU and i set it to 1450 and 2000 as you and 12 mv core , but when i was playing tomb raider it gave me black screen crash - no signal , i raised up to 35mv , but my question is whats the power limit you used? +50%
And some people recommend to tick force constant voltage in msi afterburner , but i dont want to use it really.

Dial down the core clock, not all chips OC the same, i have also suffered similar black screens when i had Core to 1480+ so i'd stick with 1450 for perfect stability and use your +mv wisely, i'm just using +30 mv max and never set constant GPU voltage.

Yes set the power limit to max it won't hurt the GPU.

Also try using TRIXX with these settings and see if you get a black screen because TRIXX handled OC stability better than MSI but MSI has better features hands down.

Yes thanks, actually already did 1450 and 2000mhz with +0.25mv and +50% power (with no forcing constant voltage) currenly run stable on ROTR , i tried to test with ugine but after install i am loading the shortcut on desktop and basicly small black windows shows, disappear and then nothing opens so my testing will be with gaming . I am using afterburner only , without installing ati settings ( i dont want Wttman conflicts), but one day when i buy freesync monitor i guess i will need the settings of radeon so i can activate it.

If it works fine then go ahead, i could get my GPU squeeze to 1500Mhz +100mv in AB but after long hours gaming it crashes with black screen so went to 1450 with +30mv but remember you can go past +100mv to +200mv max using TRIXX for additional OC headroom.
Heaven Bench never fails for me @1500Mhz Core so don't depend completely on it. Real time gaming will show you real results just give it time.

Yes, but why i would go over 1450 mhz lets say to 1500 or 1550mhz , +50/100 mhz = 3, 4 fps boost of the price of a lot of heat and up to +200mv , i believe that this not really worth , 1450 is fine i guess. and i did not measured the wattage but overall gpu oc wattage will be i guess 300w when normally card eat 190.
