So i decided to test out overclocking my R9 280x. I overclocked it using AMD overdrive and i started out pretty slowly. Upping the GPU clock by 5mhz and the memory by 10mhz at a time. Unfortunately it wasn't until about 100mhz overclock that i could actually tell the difference. I got about an avg increase of 5-7fps and and the minimum fps increased by about 8fps, but then it crashed lol. I just restarted and set it back to defaults and everything is fine. So my question is, is there a safer way to overclock without crashing? Or should i just not bother.

P.S i adjusted the fan speed accordingly so overheating wasn't the issue.

at some point you will hit a limit and it won't work beyond that, you've found it, you could up the voltages a little, but that increases risk, and you sound risk adverse.

however the way that the 2XX's are OC'd might be different I think you are talking about a power and temp limit rather than a direct OC as it will naturally ramp it's speed up to meet a power and temp profile. Read some of the reviews on OCing a 280X and you'll see what I mean (I hope). http://www.hardocp.com/article/2013/10/14/asus_r9_280x_directcu_ii_top_overclocking_review/#.U4h3s_mg0mo

Nope you overclock until it crashes and after it crashes you back off until it runs stable

As far as needing to overclock unless you are around 30fps in a game I would not bother overclocking. If you are getting good fps already no reason to add the extra noise and heat

^ +1 to that, unless you want to start messing with voltages i would back off by about 5 to 10 mhz and then work on the other clock speeds.
also dont just stress test it with 1 program, use a variety of games / stress testers because who knows what will be considered as stable and what wont, you may be able to run furmark but a demanding game may overflow your gpu etc

Thanks. Yea for a good amount of games i'm maxing them out 60fps.

Memory is sensitive on your GPU. The stock speeds the cards come with are going to be pretty close to what it will do without causing problems. Unless you happen to get very lucky and just get a card with some very high binned memory chips, small increases in memory speed can cause instability much quicker than playing with core speeds.

Overclock by raising the core speed first, once you achieve the maximum core speed you can and remain stable, then you work with the memory in very small amounts.

Thanks for the advice. I was overclocking them both at the same time and the memory clock was quite high. Maybe i'll lay back on that.

jitpublisher, Is dead on the money, many cards are already at their memory threshold as far as speed is concerned, and the GPU temperature is not reporting what the memory temperature is actually reaching, and a crash is a warning to back off, or suffer the consequences.
