Below is a little tweak I am using to get around 15% extra from my GPU, I couldn't find anything online about clocking this specific model of the R9 280X so I hope this helps. Obviously each card varies but this works for mine and requires minimal changes. I am running at 29c at idle and max temperature of 70c under heavy load (using Heaven benchmark). Playing FIFA 15 and Titanfall on ultra settings and max AA I rarely hit temps over 60c.

Definitively more potential here without the need of further cooling (yet), I will tweak further over the next couple of days and post my findings.

Look fella, I have mildly overclocked in the past and class myself as a casual overclocker... If you think I am heading in the wrong direction please elaborate. The above clock has been stable under two hours of heaven and fine under a few hours of gaming on ultra setting.

Core Voltage is a little bit too high. You can play it around 1130++ not 1200.

Try this,

VDDC - 1135
Core clock - 1100
Mem clock - 1500

Note: 1200 VDDC is a little too high for your Core clock.

The stock Core voltage is 1144mv.
Stock core clock 1050
stock memory clcok 1500

OK so bump your core clock to 1100 and mem clock to 1550 without changing the core voltage. After this, stress test your GPU.

I have been fiddling further throughout the day and I managed a very similar stable benchmark as my original post on the following;

core voltage 1150
Core clock 1110
Mem clock 1600.

How much swing do I have with the 280x before I risk shortening the lifespan of the components? I take it the card isn't the greatest OC card. As I said I have researched, but finding results ect are very few and far between... Just basic guides saying to tweek the variables until you encounter problems and then drop back to the last stable clock.


I stress tested core and mem before I started changing voltages and got to a stable 1100, 1560.

Yes because your GPU is highly overclockable so small boost to performance is easy, however if you will boost your coreclock higher than 1200 and your mem clock higher than 1600 in this case you will have a long time on tuning it to its exact voltage.

Your advice is much appreciated fella.

Most r9 280x don't get above 1150mhz on the core, as that's the usual limit on the cards. So this is a pretty good overclock for what it's worth. 1.2v is fine on the r9 280x because it's just a rebranded 7970, all the 7000 series can take up to about 1.25v, sure it does take down the lifespan but so does any over-volt.

Although like iamlegend has said why leave it at 1.2v if you can get the same clocks with less heat and damage, the 280x don't reach much more past that,
and next time put a question in your forum post or people like me just won't answer or just put an answer not worth reading.
