Freezing on screen after GPU overclocking
Freezing on screen after GPU overclocking
I've tested my Sapphire Radeon R9 290 Tri-X with +30mv, 1190 core clock, and 1450 memory clock. It ran smoothly in Uningine Valley without any artifacts or crashes. However, after about 20 to 30 minutes, the system would freeze. With a 600 watt Corsair power supply, I'm wondering if it lacks sufficient wattage for higher overclocking with increased MVA. I don't recall freezing during overclocking without extra MVA, so it might be the cause.

I own a Sapphire Radeon R9 290 Tri-X and after increasing the overclock settings to +30mv, 1190 core clock, and around 1450 memory clock, I didn’t encounter any artifacts or crashes while running Uningine Valley. However, after about 20 to 30 minutes—possibly even less—I noticed my computer would freeze. With a 600 watt Corsair power supply, I’m wondering if it lacks sufficient wattage for such an overclock. I don’t think I felt any freezing during the overclock itself, so it might be the card’s performance that’s limited, not the power supply.

I used my Sapphire Radeon R9 290 Tri-X with an overclock setting of +30mv, a core clock of 1190 and a memory clock around 1450.

With a 600 watt Corsair power supply, I’m wondering if it can handle the increased voltage without overheating. I don’t think I felt any freezing during the overclock without adding more voltage, so maybe the problem lies elsewhere. I’m not sure if the power supply is sufficient for such a high overclock. Also, why did you choose +30mv? Could you share your card’s stock speeds so I can evaluate the overclock level?

I don’t think I felt any freezing during the overclock without adding more voltage, so it might be the draw issue rather than the power supply itself. It seems like the card isn’t doing well with the current settings. Tone back the overclock or turn it off completely—you should be fine. No need for a new power supply. By the way... why did you add +30mv? Could you share your card’s stock speeds so I can check how much overclocking is possible?

I don’t recall any freezing during the initial overclocks without adding more memory speed, so it seems the problem might lie elsewhere.
I believe your GPU isn’t handling the increased mv well, possibly due to subpar overclocking skills or a weak silicon. You could try lowering the overclock slightly or shutting it down completely. A new power supply isn’t necessary.
By the way... why did you add +30mv? Could you share your card’s stock speeds so I can evaluate how much overclocking is possible? My current speeds are 1000 cores and 1300 MB/s.
I usually adjust by adding 20 to the core clock each time, then run a 10-minute stress test in Unigine Heaven, Valley, or Superposition. If artifacts appear, I reduce the clock by 15 MHz and increase memory by 50. I keep raising the clock until it hits its maximum, but I rarely go beyond 25mv.

However, after about 20 to 30 minutes—possibly even less—I started seeing the system slow down. With a 600 watt Corsair power supply, I’m wondering if it lacks sufficient wattage for such an overclock. I don’t recall any freezing during those sessions, so I think the problem might lie elsewhere. But I’m not entirely confident.
I suspect the issue could be related to the card’s overclocking capability rather than the power supply. It might help to lower the overclock slightly or disable it completely. No need for a new power supply. By the way... why did you choose +30mv? Could you share your card’s stock speeds so I can evaluate the overclock level?
My usual approach is:
- Increase core clock by 20 each time, then run a 10-minute stress test.
- If stable, add another 20 and repeat.
- When artifacts appear, reduce clock by 15 MHz and raise memory by 50.
- Continue adjusting until full limits are reached (usually not exceeding 25mv).
- Keep iterating to find the optimal setting.
Thanks for your help! Testing thoroughly is key, good luck!
Reset the OC to stock values. Adjust the sliders/numbers slightly on boost clock, testing each change before increasing further. Continue this process until the GPU shows instability, then reduce one setting. Repeat the same steps for memory. Once both stabilize, increase a small amount of voltage/power and attempt to maintain clock speeds, then memory. Keep repeating until no stability is achieved with any adjustments, then lower one setting again.
