Gpu Overclocking issues

GPU: Sapphire r9 290 Tri-x OC edition
So i recently started overclocking my Gpu, using MSI afterburner. I began with overclocking the clock speed, and had everything running fine being able to hit 1090mhz. Than I began overclocking the Memory clock, and things began to go wrong. The stock speed of memory was at 1300Mhz, i turned it up by 10-20s and finally hit about 1475, where the screen went blank once i booted up Unigine Valley to test it out. I looked at guides and they said to reboot once you crash or black screen, but when i booted up the screen would go black again after i had signed in (windows 10) This kept happening, so I restored my computer to a later date, and everything worked fine. But now Im scared to overclock my gpu again, since i don't want it to black screen and keep black screening after reboot. Any tips or reason to why this happened? (I feel like MSI afterburner kept the settings the same after the reboot, thats my theory) and if MSI the problem, are there other better programs that wont keep the settings once i reboot? -- Sorry for the long story, and thank you for your time--

when you buy an OC version of a GPU, they are usually already pushed as far as they can safely go. The gains are not worth the life span shortening, anyway, in my opinion. Did you increase the power limit when you were attempting your OC?

Yes i increased the power limit the the max it would go (50%) I followed what others did in their tutorial videos.
 


It's likely that is just the limit of the card, its harder to OC the memory on the GPU than the normal clock in my experiences.

Ah ok, after the restore, I began using the AMD Crimson driver to overclock instead, getting 1087mhz, and 1350mhz memory without increasing power limit at all, you said the life span can be decreased, how much do you think this would decrease it? The max temps Ive seen it was at 80c max, with the Vrm at 87c max
 


A GPU is rated for the 90s easily, but around 80 i worry. There is no way to say for certain, but if played an hour of video games a day with the GPU hanging around 80-85C, i would imagine losing up to a year or more of potential lifespan..

Heat is what breaks components. GPU is cold, turn on PC and play a game for an hour, it gets very hot and metal starts to expand (slightly..), then it shrinks when it cools down. Repeat many times, and it starts to brittle, and eventually break.

Keeping temps low is key to longevity in any computer component.

I think a custom cooling profile should drop it to 75s, since im using the auto adjust fan, i don't think im using the triple fan to its potential. Since the gpu runs very quietly and only hits about 30-50% fan speed i believe.
