R9 270x Overclock | Uningine Valley Fails, but temps are fine

[RedSky_Eagle]

So I am attempting to overclock my r9 270x, but it would seem overclocking is a bit tricky here. You can't raise the voltage, only the power limit, but when the power limit is raised, Valley fails regardless of clock speeds. In my last test, I ran 1225 MHz (GPU) with 1450 MHz (Memory) and it crashes, Ark does also, however my temps are fine. Is there a resolution to this or am I forced to stay at 1200 MHz and 1425 MHz even though my temps are maxed out at 60 C under heavy load?

For added information, I've used MSI Afterburner and TriXX to overclock. My setup is:

FX-6300 6-core 3.5 GHz OC'd to 4.5GHz
r9 270x as stated above
16 GB DDR3 1600 MHz/1833 MHz
ASUS M5A9 MOBO

Temps are not the only thing you are watching for when overclocking hardware.

Instability is another thing. Which is what you are experiencing. Your card might just not be able to hand it.

If temps were the only thing holding back hardware from being overclocked we would all be running full water cooling! 😛

Edit: BTW solid overclock on your CPU.

Just a new update, playing Ark, it crashed on me again. This was at 1200 MHz and 1425 MHz. I don't see how my card can't hand a +60 MHz | +25 MHz clock. Something doesn't seem right to me. If thats as high as I can go, I will most likely just leave it at stock, seeing as a +50 or less will not be worth the trouble.

Thanks! CPU runs steady at 51 C also, so I could go to 4.7 probably, but I don't want to shorten its life any more than necessary and with my current graphics card, its sort of the bottleneck in most games anyways. Doubtful that 4.7 would get me anywhere considering. Ill be switching to intel | Nvidia within the next few years anyways.

I have had cards in the past that I couldn't overclock in the slightest. I even had a 7970ghz that I had to underclock to get it stable before I RMA'd it.

Having a locked voltage is probably the biggest problem as well.

You won the CPU silicon lottery but may have lost the GPU one 😛

Btw, voltage is really the only dangerous part. If you can hit a higher core clock on the same manually set voltage as your 4.5ghz over clock.. There shouldn't be any added danger.

Ah. I see. Well that sucks, but its alright. Maybe Ill upgrade to 290 or 300 series in the near future. Thanks for all your help, I think I may try for 4.7!

There are some solid deals on the rx 480 and gtx 1060 cards atm. Plus when the 490 and 1080 ti come out the deals will only get better 😛
