My rig now so much stable and power efficiency just skyrocketed. I’m so grateful to both of you guys for sharing this and I’m so happy that I found this thread. The first card has core clock -400, others have 0: I’m still experimenting with diferen modes and values. Actually his cards would be as much or even more happy on 885.įor my 3070s I set -400 for core clock in OS and then set 690 in nvidia-smi and it is closely the same as set 0 core clock and 1080 in nvidi-smi (that value changes in increments of 15 that’s why it is not exactly 400).īut looks like using this trick helps to save couple of watts and couple of celsius. That is why j2h4u has his cards happy on 900 (he has -200 core on screenshot). Nvidia RTX 3060 Ti 8GB 1425/8100 62.01 MH/s 120 W 43☌ / 65%Īlso it seems that value you set via nvidia-smi is dependent on value of core clock set in OS. Try to set 1420 (+/-15) and it will be happy. I have a laptop with an RTX 2070 and voltage cannot be controlled with Afterburner on it.3060ti is unhappy because its sweet spot is much higher.
If you have done that and the voltage controls are still disabled, it is because the GPU doesn't support voltage control, or Afterburner doesn't support that function on that GPU. If you have a card that crashes when overclocked too much, it takes a lot longer to find the right clock speed because it may run OK for a few minutes or even hours before problems occur.įor the MSI Afterburner question, you have to enable voltage control in the settings. It's actually nice when you have a card that just has a slower hashrate when overclocked too much-that makes it very easy to tune to the optimal clock speed. When the memory is overclocked too much, the card will either crash, return some percentage of bad data, or slow down due to errors. I have two GPUs that are the exact same make and model, for example, and one can be overclocked +1400 while the other one will only tolerate +750. The manufacturing processes used to make memory and chips are designed to make them work at a certain clock speed, and if they work at a much higher speed, it is just luck. Well, they’re both useless, to be fair, as the actual frequency your card will run at is neither of the two numbers: it’s a third number that isn’t quoted anywhere, and depends on your case and pow. The highest clock speed it can work at differs on each card because the hardware is not exactly the same. Answer (1 of 4): Base clock is guaranteed clock within TDP limits, boost clock is kind of useless. The memory on a given card will only work well at a maximum given clock speed.
