Issue with XT not achieving maximum clock speeds?
Issue with XT not achieving maximum clock speeds?
I use Radeon software to optimize my card for mining, but the memory speed remains around 10-12 MHz even when I set it higher, and the core clock is about 3 MHz instead of what I expect. Also, the voltage stays at 662 mV despite being adjusted to 765, which could be affecting performance. The CCP clock is at 1250 MHz, MCLK at 2100 MHz with fast timing active.
The memory frequency is completely fine, and my 6900xt shows the same pattern too. This seems to come from AMD’s firmware. The voltage issue likely stems from a driver problem that prevents it from reporting the actual voltage, causing your voltage setting to be ignored.
In Radeon software, performance can exceed 2-3% due to intricate calculations involved in core/VRAM optimization. For instance, with a core speed of 2600MHz, it often fluctuates between 2450MHz and 2600MHz based on the game being played.
I should mention that if the component seems to work at the intended frequency but isn't precisely on it, one shouldn't be too concerned unless the difference is around 2-3%. However, this also depends on understanding the clock inputs, which we don't receive from a video card.
If it's not hitting the desired frequency range, there must be another factor limiting its performance.
In any scenario, I've noticed some individuals getting anxious when their part is set to a target frequency of 2,000 MHz but reports show around 1,995 MHz.
Yes, it's not necessary to worry if you're near a locked frequency. However, the Radeon software often interprets your MHz setting as a suggestion. In some games that demand more performance, it approaches 2600MHz, while in others it stays below 2500MHz. I haven't explored MPT yet because none of my runs drop below the FPS I'm comfortable with, and I'm still handling this card carefully.
