On the main page, the Ryzen DRAM calculator recommends a tRFC value of 288 for my RAM. However, my UEFI also asks for values for tRFC2 and tRFC4. Those values are not given on the main page. I found an online article that says tRFC2 should be (tRFC / 1.346), and tRFC4 should be (tRFC2 / 1.625). That yields values of 214 and 132 for tRFC2 and tRFC4.
However... On the "Additional Calculator" page or the DRAM calculator, there is a calculator for the tRFC, tRFC2, and tRFC4 values. When I plug in the values required, obtained from the main page, that calculator gives values of 390, 290, 178 for tRFC, tRFC2, and tRFC4.
Can someone explain the three tRFC functions - and which set of values I should use???
