R9 270x at 270x overclock works well, temperatures remain stable.
R9 270x at 270x overclock works well, temperatures remain stable.
I'm trying to push my R9 270X overclocking, but it seems challenging. You can't increase the voltage, only the power limit, but raising the power limit causes Valley issues no matter the clock speed. In my previous test, I used 1225 MHz for the GPU and 1450 MHz for memory, which caused crashes—my GPU also did, though my temperatures stayed normal. Is there a solution or should I settle for 1200 MHz and 1425 MHz even though my temps hit 60°C under heavy load?
I've experienced cards before that I simply couldn't overclock. Even my 7970ghz had to be underclocked for stability before returning it for repair. A locked voltage seems to be the main issue as well.
You might have won the CPU silicon but lost the GPU.

In any case, voltage is clearly the most critical factor. If you manage to achieve a higher core clock at the same manual voltage as your 4.5ghz overclock, there shouldn't be any additional risks.
For further details, I've applied MSI Afterburner and TriXX overclocking tools. The configuration includes:
FX-6300 with 6 cores at 3.5 GHz, boosted to 4.5GHz
r9 270x as mentioned earlier
16 GB DDR3 memory running at 1600 MHz/1833 MHz
ASUS M5A9 MOBO case
Temps aren't the sole factor you should monitor during overclocking. Instability is another concern, which is what you're encountering. Your card might simply not be capable of handling it.
If temperatures were the only barrier, we'd all be using full water cooling! 😛
Edit: Also solid overclocking on your CPU.
Faktion :
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've experienced cards before that I simply couldn't overclock. Even my 7970 reached its limits, requiring an underclock to achieve stability before returning it for repair.
A locked voltage seems to be the main issue as well.
You might have won the CPU lottery but lost the GPU one

By the way, voltage is clearly the most critical factor. If you manage to boost a higher core clock at the same manual voltage as your 4.5ghz overclock, there shouldn't be any extra risks.
I've experienced cards before that couldn't be overclocked at all. Even a 7970ghz needed underclocking to stay stable before returning it for repair. A locked voltage seems to be the main issue as well.
You might have won the CPU silicon but lost the GPU in the lottery.
By the way, voltage is clearly the most dangerous factor. If you manage to reach a higher core clock at the same manual voltage as your 4.5ghz overclock, there shouldn't be any extra risks.
Ah, I understand. It's not great, but it's okay. Perhaps I'll upgrade to a 290 or 300 series soon. Thanks for all your advice—I might aim for 4.7!
