.... go back, and read the definition of "double data rate"? You're doing well, if you have 3800 RAM synced 1:1 with 1900 FCLK.I don't know what to do for coupled mode.
Before it was set for Auto, then I changed it to 1800, half of 3600
now 1900 set it up for half of 3800
Which is half of it.
I am not sure what do I need to match it ?
CPU Clock ?
I would like to answer you, however I do not understand what you are asking ?I am curious what VSoC you are running for that level of FCLK? You will want to be sure it is not too high if left on auto.
Understood.VSoC is the voltage for the memory controller, IF, etc, on the IO die for your CPU. Sometimes you will need higher VSoC than default for higher IF clocks, such as 1900MHz and higher.
From the post above, it looks like it is 1.1 Volts. That is fine.
