The effective memory clock to default memory clock calculator uses the memory type and effective memory clock to calculate the normal memory clock. The normal memory clock is the speed at which the chips on the GPU are running at which doesn’t take into account how many times the data can be sent per clock cycle.
To get the normal memory clock from the effective memory clock, you will need the effective memory clock and the memory type. The memory type will have a number of times it can send data per clock cycle. The equation is: Normal Memory Clock = Effective Memory Clock / number of times that type of memory can send per clock cycle. For GDDR5, the number of times it can send data per clock cycle is 4.

The Nvidia GeForce RTX 3060 has a memory clock effective of 15 Gbps and a memory type of GDDR6. GDDR6 can send 8 times per clock cycle. The equation is therefore, Memory Clock = 15 / 8 = 1.875 GHz or 1.875 Gbps. You can then times by 1000 to get it in MHz or Mbps. So the answer is 1875 MHz or 1875 Mbps for the normal memory clock speed.
Use the table below to see the number of times each memory type can send per clock cycle.
