R9 390 Won't overclock higher

[Xplod2064]

Hello all

 

I have been trying to overclock my MSI R9 390 from 1060MHz, I have managed to get it to 1120MHz stable but it artifacts if I go higher?

Thermals are all fine under 75C easily, Mainly high 60s to low 70s under load and it has a EVGA G2 750W Supernova giving it power which I have allocated max power to

 

Any suggestions? BTW I have not touched voltage which could help it but not 100% on the voltage part of O/C.

WHICH MSI R9-390 do you have -- can you give us the model number?

What software / program are you using for your overclocking?

 

Keep in mind, you could have two settings: Power Limit, and Voltage.

They are two different things.

 

As you mentioned, power (e.g. PSU) should not be a problem.

 

What is the stock voltage for your particular R9-390?

 

How are the temperatures for the VRMs?

GPU-Z (I think MSI Afterburner as well) should give you these temperature readings, along with GPU temperature.

 

I've checked a few R9-390 reviews, AND our very own GPU overclocking database; most 390's sit in the 1125 ~ 1160 MHz range.

You should be able to push the overclock a tiny bit more with more voltage, but don't anticipate 1200 MHz or something.

I had MSI 290x that wouldn't go higher than 1120mhz without adding too much voltage.

Ill have to look for the model number but this is it https://www.msi.com/Graphics-card/R9-390-GAMING-8G.html#hero-overview

I am using AMD Wattman Or MSI afterburner either one works.

Stock voltage is in the screenshot which is factory default.

VRM's are about 1-2C higher than the GPU itself, But ill check that again and let you know.

Ah, okay.

State 7 is already at 1.275V -- which is pretty standard.

 

You can try pushing it up +25mV (bringing it to 1.300V) and see if that helps.

Afterwards, increase your voltage in 10mV increments, while keeping an eye on all your temperatures.

 

I'm not sure what is the maximum voltage limit Wattman will allow (I use Sapphire TriXX for my R9-Fury's), but MSI Afterburner's limit is ~100mV.

+100mV already puts you at 1.375V -- which is quite high...would not recommend going higher.
