![]() ![]() ![]() ![]() 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. The highest clock speed it can work at differs on each card because the hardware is not exactly the same. The memory on a given card will only work well at a maximum given clock speed. ![]()
