Safe overclock?

[Chapapa07]

I overclocked my gpu core (xfx r7 265 core edition) from 925 mhz to 1050 (msi afterburner limit) and set the power limit to 20%, then I went to another room for watching a tv program while my pc was loading the witcher 3 (eurogamer console settings) to the title screen, after 2 minutes I went back and there was black screen and a sound loop/buzzing, I pressed the reset bottom twice of my case and after 5 seconds my pc turn itself off and it turn itself up.

Well, since I didn't watch if the gpu got too hot and considering that this overclock wasn't on the high side, I was unsure if this OC was the culprit, so I decided to apply the same overclock and try to play again....., I played for 50 minutes with no problem whatsoever, later I played gta v (eurogamer console settings) for 1 hour with no instabilities, then ran 3dmark vantage in performace preset, saw a 10% increased, checked if the OC was applied, it was.

What do you guys think? was the overclock the culprit? or, it was a coincidence the game crashed my system after I applied the OC?

Sounds like you fried something. Does it smell good?

 

[Chapapa07]

It smells awesome

 

[Toothless]

I had something fry in one of my PSUs. Smelled like waffles.

If it happens again cut the power by holding the power button or unplugging the cord, don't use the reset button. When I go over board with my HD7750 oc I have to do that.

It's reads like it could have been due to hw accel bug. Do you have profiles setup ion AB amd have AB set to use 2D/3D profiles?

While an overclock might seem stable some games can trigger instability rather quickly.

You can scale back to 1000 or 1025 and test with witcher3.

 

[GorbazTheDragon]

If it crashes it probably is still fine, it was just instability that caused the driver to crash and take the rest of the system with it. I can crash my laptop GPU by applying a -40MHz offset to the lowest power state (~100MHz). Unless you are still getting instability at normal clocks you should be fine.

 

[Bo$$]

it's simple. your overclock is not stable, adding voltage doesn't assure stability. overclocking that card probably isn't worth the trouble if you aren't prepared to stress test your new clocks

 

[Chapapa07]

I guess it was a coincidence, been playing for hours (the witcher 3 and gta v) with no issues at all, I'm even thinking to increase the OC lol.

 

[Schmuckley]

What PSU are you using? sounds like triggerage of ocp to me.

It maybe slight instability as you could need more voltage than your giving it for some situations. I have had overclocks stable in all but one application before that didn't showcase itself except in a few finite situations.

My advice, increase the power limit a bit more and see if it stays stable in everything you throw at it.

The power limit its at its maximum (20), and the first time I got the crash it was loading the witcher 3 to the title screen, I doubt that is more demanding that actual gameplay.

 

[vega22]

i think the r7 range were more power limited than cooling when pushed.

 

[Schmuckley]

Could be a driver issue..Try 13.9
or..blech..Omega

This. Black screen with a repetitive sound loop similar to a buzzing noise typically indicates either drivers, or the PSU isn't supplying power to the GPU correctly.

Judging by the fact it's an old OCZ Fatal1ty unit, I'd hasten a guess that your PSU is toast

Well you would be surprised what can trigger an OC fail but if your at the max keep it so and just see what happens since its not happening again. I have seen HD 7850's (Which is the R7 265) get up to 1200 but its been different variations so you should be fine.

 

[Schmuckley]

I would say try editing the BIOS and/or..Get a bigger PSU.
I had to get a bigger PSU when I couldn't OC my Deneb and a 5850 at the same time.
r7 265-70 is about on par with a 5870.
5870 textures are richer, though.

Yeah I will wait and see, I didn't increase the core clock because 1050 its the limit in Afterburner but I increased the memory to from 1400 to 1500, got a blue screen within 2 minutes of gameplay in TW3, not going to overclock the memory again.

 

[Schmuckley]

fwiw I had a 7870 and it OC'd to over 1200 core quite easily.It was not mine and I'm jelly of the owner.

 

[Chapapa07]

Final stable overclock is 1085 mhz, even at 1100 what I got was crashes to the desktop in TW3 and ERR_GFX_D3D_INIT in gta v.

Does it crash at stock?

Dont edit the bios if you don't know what you are doing.

Which most new overclockers fall under.

 

[Bo$$]

No

okay, so clearly the card cannot handle those clocks, not all cards are created equal, just because your friends card reached higher clocks won't mean yours will match it.

It is likely that your card is not a very good chip, hence won't go to the clocks you want it to. Don't blame PSU or drivers, you've reached the limit of the card, back of the clocks and find a 100% stable point.
