Overclocking a R9 380 4gb in MSI Afterburner?

[KearneyMC]

I'm wanting to get some extra power out of my card and I would like to know what clock speed and power settings would be good and it would run stable?

All GPUs aren't created equally, yours might not overclock that much while others will OC a lot.

 

Just try increasing it by 100mhz and use Heaven or a game to test OC, then increase by another 50, until it isn't stable and crashes.

 

 

I could go on, but watch this video: Both Nvidia cards, but it's the same concept.

You should increase the core clock first by about +10MHz, after each over-clock stress test with unigine heaven.

If the benchmark was stable and displayed no graphical glitches then over clock by +10MHz again and stress test.

When you reach an unstable OC or experience glitching etc you can dial back the clock speed to teh last stable OC or increase the voltage by +0.05mV.

Once you are happy with teh clock speed and/or cant go further, repeat with the memory clock. 

Once you've done that stress test with other benchmarks such as Furmark and 3dmark, watch your temps.

NEVER use Furmark. It kills cards. It killed mine ._.

Rip

what card?

It worked for my HD7950 with one fan and dusty heatsink.

R9 280 (7950) - bricked the power delivery.

Damn you get a replacement?

As someone else said, do not use Furmark it's the Prime 95 for GPUs.

 

 

Go with Heaven/Valley or 3D Mark. Sometimes a OC with pass with benchmarks but fail in games, so that's a good test as well.

Working on it

[Ansau]

Put Power limit to +20% and start with 1050MHz in core and 1500MHz in memory (this should be stable unless you have a utterly bad chip).

1) Raise core frecuency by 10MHz.

2) Boot Heaven Benchmark and do 2-3 runs of the benchmark.

 

Repeat 1 and 2 until you reach the max core frecuency with stock voltages (you should reach 1080-1120MHz at core). Now boot an intensive graphic game (BF4, Witcher 3, FC4...) and play for half an hour. If it crashes down 5 or 10MHz.

 

Do the same with memory, you can push 1600MHz and low by 20MHz if it's not stable. Memory is easier to OC as crashes happen quite fast with a green screen and you need to reboot.

 

If you still want to push it more go to preferences and click unlock voltage control and voltage monitoring. From my experience with my r9 285, +5MHz needs around +10mV, but this can vary. Note that while overvoltaging temperatures will go up quite easily.

 

*Note: There's an oddity with Tonga overclock. Tonga has middle stage frecuencies when iddling that are also affected when you push core frequency with AB. While you can be perfectly fine at full speed, these frecuencies might be too high for the voltage assignated and they can prompt crashes or artifacts. It also happens with certain programs (paint, web browsing... in my case).

This can be avoided with bios mod or some software that puts the gpu at full speed. It's also the cause of instant crash when booting GTA V.
