FSB in RAM
Short for Front-Side Bus, FSB is also known as the processor bus, memory bus, or system bus and connects the chipset. The FSB is what we have seen change from 66 MHz, 100 MHz, 133 MHz, 266 MHz, 400 MHz, 800 MHz, 1066, 1333 Mhz, 1600, 1800, 2000, 3000, and up to the 5000 Mhz range and intermediate speeds through the years.
By default, FSB speed and memory are usually set to a 1:1 ratio, meaning that increasing FSB speed by overclocking the CPU also increases memory speed by the same amount.
Your motherboard is rated at a max of 3200 MHz
Your CPU is rated at a max of 3200 MHx
Your RAM is rated at a max of 3600 MHz, but can only work at 3200 MHz because the motherboard sets the limit.
A 1:2 ratio is the equivalent of 20% increase in RAM FSB from 2400mhz to 2880 Mhz
I read you're trying to increase your 2400 MHz RAM speed to 3200 Mhz, so the ratio should be 1.33
The timing: Higher timing is supposed to transfer more data at a slower speed, while a lower timing transfers less data at a higher speed, so the ideal timing would depend on what you'll be using it for.
