Overclocking GPU

[Efanel]

Hi,

 

So I'm thinking about overclocking my GPU, and I would like some advise on how you do it.

 

I'm thinking about using the MSI Afterburner since my GPU is MSI, not sure if this matters or not

 

I read an article on PC Gamer that tells me to increase  my memory until I start seeing memory stress signals, then setting it back to default, then do the same with the GPU clock, then set it again back to default, then do it with both the memory and GPU clock, and, if stress signals appear, lower them.

 

How do you suggest to do it? Shouldn't I be able to mess with voltages too? Or is that a bit more on the expert side of OC?

 

Thanks

exactly that you OC each part separately so you limit what the causes the instability. Increase clock until it isn't stable then increase voltage. There will be a point where voltage doesn't impact stability. Be sure to watch for temps and keep them on the safe side.

so only increase voltage after finding the max clock/memory combo at stock voltage? to get some more boost?

some people say to max the voltage it allows then increase click till it crashes but I dislike this method.

 

Yes that is how you do it. Small steps keeping an eye on temps. I used a benchmark which gave a score so I could see how much it was going up.

 

I had a point where it wouldn't crash but was hurting scores.

First increase the power limit. Then increase the GPU clock speed and find the maximum that it can run at without crashing. Then try boosting the memory.

 

Some say that voltage increasing does not help on Maxwell and Pascal cards. However my Classified 980Ti does need some additional voltage (+25mV) to be able to hold it's highest overclock (1443 MHz), otherwise it would decrese to around 1400. And that is at 140% power limit (with additional voltage, my power usage remains at approximately 95-98% in games).

first what gpu if its nvida 900,1000 you can crank the voltage slider to max power limit to max and temp should automatically go to max also . download 3dmark on steam and heaven and/or valley benchmark from the their site . start with core till you crash or lockup back off a bit and do the other and then run benchmarks for awhile then play games . you crash back one off  crash some more back the other off repeat till total stable OC  . also  download gpu-z to see if your hitting card limits ect also shows the clocks in real time

I'm using MSI afterburner, and I used Heaven and 3dMark, I set the core to +150 and memory to +200, I feel like if I put a little bit more on the core, I'll see some artifacts in the form of random baby blue lines like if there was a blue scratch on the screen, these only last like for one frame so I'm not sure, also, when OCing memory at +300, on 3dMark I saw some large black blocks sometimes, but also these only lasted for one frame so I am not sure of what I saw, are these the artifacts I should be looking for when testing for the max overclock?

 

Do you think I should be able to overclock more? Im using a 970

 

Also, what are good stress tests to check for stability after I overclock?
