How far is too far when overclocking your GPU?

I've never overclocked my GPU before so I'm rather weary of what settings to put it at. I have an Msi R9 270 Gaming Edition graphics card (OC out of the box) with an FX-6300 and a 450w XFX pro core edition power supply. From what I've seen people are using the temperatures as a guideline to when you're overclocking too far. I downloaded MSI's Afterburner program and you'll see from the attachment what I set the settings to. Would it be safe to bump it up further? And how would I tell when I should be stopping?

The Kombuster app was running in the background hence the spikes.

It's not just temperature you have to look at. Too much voltage will really shorten its lifespan. I'd say set a reasonable goal (20% increase of core + memory over stock maybe) and work to that. Temperature is just the easiest way to see if the OC works (and stability of course).

Check what the max voltage the card can safely operate at and overclock as much as that voltage will allow. For temps simply adjust fan speed so it stays under about 80-85C.

Frankly, when you no longer have stability, or when your temps get to high. Run a stability test after overclocking.

Use the Kombuter burn in to test to see if youre getting "artifacts." This is when the graphics start to screw up, before freezing the card and you have to reboot. Keep increasing the numbers until you start to see artifacting - then back off a bit on the increases. This is likely your stable spot. Best test is running a full video game afterwards.
Without being able to control the core voltage of the card, you won't have to worry about temperature. Also, not allowing for voltage increase won't give you much head room for overclocking.

Most of the time people push the card as far as they can before the card becomes unstable and crashes out. You are going to get different results even if you have the same card. If you push your card to far it will become unstable and crash, that means you need to turn your settings down until you can get a stable OC. You do want to keep an eye on the temperature though, if you run to hot your card will down clock so you don’t do any major damage to your GPU. Having said that the lower you can keep the temps the better.
