Two guides to go by:

http://www.kitguru.net/components/graphic-cards/zardon/sapphire-r9-280x-vapor-x-oc-and-r9-290-vapor-x-oc-review/30/

Both overclocks are higher than what you need though. All good results though

Use software supplied with GPU from Sapphire or the best use MSIAfterBurner as it gives more stable overclocking. To overclock the GPU, don't straight forward increase the voltage (you would need to unlock the voltage control in the settings menu). Increase the Power Limit on the main page from 100 to 104 or 106%. Ensure that Link checkbox is selected. You may want to leave the temp target to 90 or so.

Run the stress on stock settings for the first time.

Now start increasing the Core Clock and Memory Clock by small values like +10/+15 and run stress test like 3D Mark Fire Strike or Sky Diver or Heaven/Valley benchmarks from Unigine. Keep an eye on the screen. You should not see any objects/artifacts or driver crash/failure. you can also use FurMark for stress testing.

With every successful stress testing, keep on increasing the value in Core/Memory Clocks and stress test till such time drivers start to crash or artifacts start to appear on the screen. Use the last successful Core/Memory clock values for overclocking.

Good Luck.

Will it harm my gpu if it crashes or artifiacts appear on the screen.Like i mean i dont want to bust my graphic card

EasyLover · Sep 15, 2014

No, it will not if you reset the values to last known worked values or completely reset the values. Point is the patience involved in the overclocking process. Don'tr jump start with something like +100 on core clock for example.

EasyLover :

Ok.So which one should i start with,the power limit memory clock and core clock?

EasyLover · Sep 15, 2014

Yes, first increase the power limit. Then increase the core clock. Then increase the memory clock (Increase in memory clock is generally higher than increase in core clock). Apply the settings. Run the stress test.

Whenever i start the stress test my UPS starts making beep sounds.Why is that?

EasyLover · Sep 15, 2014

Hmmm! Your PSU seems to be not coping well with the overclocking.

KarthikNS · Sep 15, 2014

EasyLover :

The max i could overclock is 50 mhz for each core and memory cause after that the drivers are crashing

EasyLover · Sep 15, 2014

Every chipset is different and has different overclocking potential. Good if you are able to overclock it to further 50MHz. Please remember there are number of variables at play like drivers, airflow inside the case, air cooling vs water cooling etc.

If you want to overclock it further then, you can increase voltage but if you are not comfortable then I would not recommend doing it unless you read about on how to do it.

The FX-8350 is a power hungry chip, and the 280x is pretty power hungry too. That cooler master power supply is practically garbage, and you shouldn't be overclocking at all with it. You are taking too big a risk for so little a gain IMO. Replace your PSU with a high quality one, and you should see much better overclocking results.

EasyLover · Sep 15, 2014

Sorry for late reply. Your PSU is not in first three tiers of the list. Better change this PSU to tier 1 or tier 2 A/B class PSUs. Don't overclock your components till you change your PSU.

Ok i wont overclock but even on stock setting why am i seeing artifacts in Watch Dogs?

EasyLover · Sep 16, 2014

Watch Dogs at what resolution and at which game settings: Low, Medium, High or Ultra?

KarthikNS · Sep 16, 2014

EasyLover :

Watch Dogs at 1080p (high settings)

EasyLover · Sep 16, 2014

Well that is strange! Did you check other games? Watch Dogs is a very demanding game not only on GPU but on CPU as well. But your system other than PSU seems to be well equipped to handle it.

EasyLover :

Umm i really dont know if its an artifact or a small glitch.Its not big black dots on the screen.I think its the rough edges on the game because im playing with AntiAliasing turned off.I think i will provide a screen shot to make you understand better.

Edit:http://i58.tinypic.com/zva64j.jpg here is the link to the screenshot.I'm talking about the black marks on the train tracks.

EasyLover · Sep 17, 2014

This is not an artifact but part of game play/rendering in watch dogs.

KarthikNS · Sep 17, 2014

EasyLover :

Oh ok ,so there is no problem in my card right?
Edit:http://tinypic.com/view.php?pic=4syzgo&s=8#.VBlovPmSwi4 What about this pic.The black marks in front of the headlights,is that anti alisaing or an artifact?

No, not at all.

EasyLover · Sep 17, 2014

This is worth looking for sure. Pl trun on AA settings and play at 4x. Check if you are experiencing the same game play or otherwise please.

http://tinypic.com/view.php?pic=14ad7qt&s=8#.VBl_kPmSwi4 Anti Aliasing is set at MSAA 4X but i still see this problem.
It's happening only in Watch Dogs though,other games like assassins creed 4,saints row 4 etc.have no problems at all
