980 Ti overclock - What's the limit for a 65.5% ASIC?
980 Ti overclock - What's the limit for a 65.5% ASIC?
I tried to exceed the original specifications by increasing the base and memory overclocks by 200 MHz. After doing this, the Nvidia driver stopped working and later recovered. The event ID was 4101. I kept letting the computer fold without further crashes, but I'm unsure if one crash was directly linked to the overclock increase. I haven't played any games since then.
It seems like the current setup is primarily driven by GPU performance. The base clock isn't as crucial as the boost clock, which Precision X will display when GPUs operate under specific conditions. At 1406, your maximum boost clock is reached with the overclocking (OC) applied.
For best results, begin by tuning your core clock first and achieving a consistent OC before addressing memory. This approach prevents overloading both components, ensuring stability. Monitor temperatures closely, as GPUs tend to throttle slightly with rising heat. Adjust core clocks gradually in steps of +20-25Mhz until you reach optimal performance.
Also, based on GPU-Z:
GPU Core Clock: 1253 MHz
GPU Memory Clock: 1652.4 MHz
Let me know if you need more details.
I increased the core by +200 right away... that's a lot, right? If it's already at 1253, pushing it over 1550mhz is possible. On my 970 I'm getting around 1554mhz, which is the maximum and at 74% ASIC performance. I think it's best to increase in steps of about 50mhz. I believe you could reach around 1500mhz. For memory, I can handle an extra +500 without issues, but overclocking memory doesn't help much. And yes, if it crashes even once, it's likely to happen again, especially during games.
You need to monitor overclocking closely on the CPU and GPU for folding. Occasionally it might lead to your work units being rejected due to excessive errors.
the core is 1253 after overclocking? that's not that high, you likely increased the memory clock too much.
I increased the core and memory clock speeds by +150 MHz. The Precision X reported GPU clocks at 1406 Mhz, then decreased to 1392 and finally 1372. Is this typical behavior or does it suggest thermal throttling or instability? The GPU temperature target is set to the default of 83°C.
It seems like you're just noticing the usual performance boost from your GPU. The base clock isn't as crucial as the boost clock, which is what Precision X will report when your GPUs are operating under certain conditions. At 1406, you reach the peak boost clock with your overclocking settings.
Here are some tips: begin by tuning your core clock first and achieving a consistent overclock before moving on to memory. This approach prevents you from compromising stability by adjusting both at once. Once you have a stable core, you can proceed with memory tuning. Keep an eye on temperatures since GPUs tend to throttle slightly as temperatures rise. You should increase your core clocks in small steps of +20-25Mhz until you find the optimal balance. For memory, you can raise it in +50Mhz increments and see what the maximum performance is.
My original kingpins were set at 1443Mhz core/7092Mhz memory, while with my current overclock I'm running 1500Mhz core/8000Memory.
