Can damage be done by overclocking even if my temperatures are stable and my computer doesnt crash during stress tests?

I have a potato of a computer, (for running the games I play) and I'm a little new to the overclocking world. I read in another forum that there can be damage to the gpu even if temperatures are low. Could anyone support or deny this claim?

I have a Radeon r7 m265 (store clock @ 825 Mhz)

I've been able to OC to 1020 Mhz (safely?) with gpu temp at 68C and no crashes during Unigine Valley Benchmarks (I haven't touched voltage). But I have a gut feeling that this OC is ridiculous. Is my gut right? And I've only found one other guy who overclocked the same card to only 960 Mhz. (I'll stick to 960 for now, out of fear, or at least until one of you kind folk help me)

I haven't touched memory clock yet (store clock @1000 Mhz) The vrm temperatures are not shown, so I don't really know how far I should go.

Any feedback will be greatly appreciated!
Thanks in advance =)

It's called electro-migration, it's where literally the tiny voltages in the cpu leak from one point to another. This happens anyways with time to every cpu, IC chip, ram etc. OC just accelerates the possibility. Considering a cpu can easily last 20years+ with normal usage, even cutting that in half still gives plenty of room. I have a Pentium II 350MHz on an Asus p2B mobo that still works, even oc'd to 400MHz (hasn't changed since Christmas of '97), so unless you are severely pushing or exceeding rated voltage/current limits, OC damage is not something that's generally going to affect your pc usable lifetime.

I suppose you are capable of damaging anything even at stock speeds... Just like people twist an ankle walking down a hall... Personally I wouldn't OC any further based on a risk/reward consideration... How much performance are you going to get for your risk...

Good Point. I'd rather not blow anything up.

I just checked my 660ti, it's currently clocked at 210MHz higher than reference, and memory is 816MHz higher. And that's with a 114% power level. I'd say there's room for your OC to be fine. What I would do is download MSI Kombuster and run the full gamut of tests, blender, donut, Julia etc as that'll stress the gpu out in more specific areas. If it'll pass all those with no issues, then try something like Firestrike which'll really punish the card. If that'll pass without topping out the heat or blackscreens, I'd say the OC is good for clock speeds, but I would drop it some in favor of bringing up memory as well.
