Overclocking R9 280x Sapphire Dual-X

[DiX0Pi]

So I got an r9 280x and I use the program AMD Radeon Settings (Right Click Desktop) and I'm wondering what the max OC would be until it gets unstable? Also is there a better software for overclocking? Thanks!

MSI Afterburner is a commonly used program and good for overclocking. I've also used ASUS GPUTweak and it worked well.

I was able to get a 25% core increase on my Sapphire 280 (not-X) a couple years back. Your mileage may vary, your best bet is to increase your core clock slowly while running stress tests in between to determine the max stable clock. I think the average user ends up stable between 1100-1200.

Usually I use something like Unigine to stress test when I'm dialing up clocks (because it's fairly quick to use and moderately difficult on the GPU). If I'm not trying to take my time I might start with a 100Mhz bump and do a quick 30 sec test for stability. Then assuming it's stable (most would be at this freq) I might add another 25Mhz and do a test for a minute or two. Then maybe another 25Mhz. At this point I'd probably drop to 5-10Mhz increments and lengthen my tests.

As soon as you see artifacts you can either add a little voltage (but be very careful and do some research on how much is safe for your core) or back off your clock, depending on how much you care to push the GPU. After you find a good stable point you can then add in a couple other benchmarks like 3dMark or boot up a game or two. If you're happy with the core clock you can then do a similar methodology for the memory clock.

Alright, I will try it, but I don't like to mess with the voltage because I'm still kinda new to overclocking and all that
