Hello , will it have any benefit to change the Command Rate from 2T to 1T ? There must be an tiny acceleration to commands coming from the cpu to the gpu, that´s my thought. Is there anything conclusive to say yes this will be accelerate the calculations by cuda or isn´t that ? For example are there benchmark results ? or anything i can compare that ? Greetings from germany |

Hello: The CMD Command rate or rate (which may be T1 or T2) is the time it takes between when the signal is given to select the memory chip to be used (can be any of the chips within each memory bank) and the beginning of a read cycle of the memory chip. T1 means that this time it only takes 1 clock cycle and 2T takes 2 clock cycles. This only affects when you first access a memory chip, then no (while maintaining access to the memory chip). If memory supports it is generally faster to use 1T to 2T. Greetings. |
