Good evening,

I'd like to try and overclock my GPU for the first time and I think I have the basic grasp on where to start. Please correct me if I'm wrong and I would be extremely grateful for any advice offered.

My system:
i5 4670K
Asus Z87-K
Corsair CX600W
XFX R9 270X - 2GB

Stock Speeds: 1050 / 1400
I have MSI Afterburner and FurMark.

I started with 1100 / 1500 and achieved temperatures of around 73 - 75*. I then went to 1150 / 1530 and the temperatures stayed the same. The system was stable. I have now reverted back to factory for the time being.

Should I be adding anything to the power limit?
What is the best use of the fan settings? At the moment I have it on auto, is this correct?
What do you think a safe overclock would be?

Any guidance would be appreciated.

Thank you.

AMD Afterburner? Do you mean MSI Afterburner, or AMD overdrive? I'm not familiar with AMD Afterburner. When you test for stability you should use more than just furmark. (unigine heaven, different games, etc) I would recommend you raise the power target/limit to 120% (max allowed I believe) and create a custom fan curve to keep temps down. Those aren't bad temperatures at all for these gpus but they aren't great. I dont care about the noise so my card is usually very cool but kinda loud. Experiment and see what suits you. Once you've let those programs run/ played games for a decent amount of time (30 mins for games/furmark at least) keep raising your core clock until you're satisfied or you're not stable. If not stable see if...

If not stable see if increasing the voltage by a bit helps. If it does, leave it or continue. Do the same for your memory frequency. For a 270X I think 1150 stable is a very good OC, though if you can push it, why not? Safe overclock is probably what you have now. Somewhere around 1120-1200 GPU and 1400-1550 RAM but if you can do it, go for more.

Thanks for the great response. I'll give you an update. I'm currently sitting on 1180 / 1460, with a temp of 70-75*. I could overclock the Core Clock further I believe and I might give that a try tomorrow. The memory clock doesn't like going higher then 480 so I figured I'd bump that down to play it safe. Fan wise I've tried to curve it. When it gets to 70* I have it up to 80%. It's loud but stable.

At the moment my PC is on the carpet under my desk. I'm going to see about cleaning it out and finding a piece of wood to sit it on. May help.

Just played Dragon Age Inquisition for a solid hour. I've noticed a nice performance boost. I may hold off on upgrading my card for a while longer.

Thanks again.

460? do you mean 1460? 1180 is a great place and if it's stable there then I would just leave that there, unless you want to bump the voltage and see if you can get an even 1200. That's a good overclock for any GCN card. Don't forget to download and run unigine heaven benchmark too when you check for stability.

1460 I meant, yes. I've just installed 3x Aerocool DS Edition 120mm Case Fans. 2x on the side and 1x on the top. They're so incredible quiet, I hope they help with the cooling. I wasn't entirely sure how to do that. I plugged in a PSU peripheral cable and piggy backed the leads. I hope that's the right way of doing it. This has been a pretty big learning experience for me.

Oddly the PSU cable had 3 pins and 1 empty and the fan cable had 4 pins that slotted into it, but it worked anyway.
