GTX 950 with overclocked performance experiences a very uncommon graphical anomaly.
GTX 950 with overclocked performance experiences a very uncommon graphical anomaly.
Hi,
I've spent a lot of time optimizing my GTX 950 for maximum performance in Assassins Creed Origins while maintaining a consistent 30FPS. I gradually increased the overclock values for Memory and Core bit by bit, monitoring them through benchmarks and reaching my limits without changing the voltage. I don’t want to risk shortening my GPU’s lifespan.
I’ve been playing ACO for about two hours now and have occasionally encountered glitches in the sky area of the map—brief flashes of black with white lines. These happen very quickly, rarely affecting FPS, and no other issues have arisen.
My current MSI specs are +120 Mem Clock, +120 Core Clock, and a 10% increase to my power limit. The voltage is set at +0 and locked.
Should I be concerned about these rare glitches? They seem minimal and aren’t impacting my gameplay much. I’m only worried about the GPU’s health, as long as temperatures stay between 65 and 70 degrees during full load. I don’t want them to worsen and cause damage. Should I revert to default settings or continue overclocking?
Everything appears normal from a safety perspective, but I'm not surprised you're encountering instability without raising the voltage slightly. Is this the 1408MHz base or boost frequency? Most 950 models come with core clocks in the 1100MHz range, and even the top models typically have around 1200MHz base. The SSC cards are boosted to 1340MHz. The best OC I've seen reports stable performance on a 950 at a bit above 1300MHz base or about 1500MHz boost, though it did require a small voltage increase to achieve stability there. *EDIT* I found it.
The occasional issue merely shows your OC isn't fully stable... but since you're not experiencing crashes or any disruptions, and it's not affecting your enjoyment, everything seems okay.
Voltage and temperatures might lead to a shorter lifespan or possible damage to the card, though a slightly unstable OC shouldn't cause harm.

The occasional glitch just means your OC isn't fully stable... but since you're not experiencing crashes and it's not affecting your experience, everything seems okay. Voltage and temperatures are the main concerns—they could shorten the card's lifespan or cause damage. A slightly unstable OC won't harm anything. Perfectly clear on that. Thanks for clearing things up, I can finally relax.

The occasional hiccup is merely showing your OC isn't fully stable... but since you're not experiencing crashes or any issues, and it's not affecting your experience, then it's all good. Voltage and temperatures could be factors that might shorten the card's life or cause damage if unstable. A slightly shaky OC won't harm anything. Are all the sensors functioning properly? If you're okay with checking, please let me know.

1.2V is not a significant jump, and it wouldn't be too much to adjust if needed for stability. It shouldn't noticeably affect the lifespan—definitely won't shorten it beyond what's expected.
Thanks for the update, I think my Shipped settings were around 1150mhz and I increased it to about 1320mhz without changing the voltage. Since I'm still getting familiar with all this, I guess I don't fully understand what I'm saying. I just read a guide and spent some time adjusting it in Benchmark, trying not to overdo it. I don't want to spend money on a new card right now if I mess up this one. Haha
I had a brief experiment with the voltage yesterday, adjusting it to +15MV and trying to reach +200 Core clock MHZ, but it wasn't stable. I didn’t understand what I was doing, so I decided to leave the voltage unchanged. Lol.
Edit. I’m having trouble getting the memory MHz close to those values in that review. I believe I’ve reached my core limit according to this feedback and haven’t adjusted the voltage much, so maybe I should increase it a bit and try again. Thanks again for the lp!
