You can download Ryzen DRAM calculator helps with overclocking your memory on the AMD Ryzen platform. It is a handy calculator that will help you make it easier to overclock the memory on Ryzen based systems.

v.1.4.0.1 (October 12th, 2018)

• Fixed Gear Down bug
• Some correction DRAM voltages for OEM
• Some correction Soc voltages for frequencies that are below 3333 MHz
• Program signature fixed

v1.4.0

• Initial support Threadripper gen 1 and gen 2
• Improved SOC voltage prediction for different processors and their generations
• Additional window that will tell what minimum DRAM voltage is needed by the system
• Additional windows that show a nanosecond delay for the current calculated profile. It will be especially useful for users who are reflashing SPD
• Improved prediction procODT + RTT + CAD_BUS for some memory (the block has endured many changes)
• Improved overclocking for Hynix CJR . Up to 3800 MHz inclusive. Big thanks @Reous for the help
• A switch has been added to define system tasks, BGS / BGSalt recommendations depend on it. Turning off BGS allows you to increase gaming performance by up to 5%
• The "Custom" profile will be based solely on the data that is placed in XMP. Its new name is "Debug". Mode designed from scratch, available for almost all chips (but still need some time for a more subtle configuration).I think this mode is needed for professionals who want to see all the changes relative to automatic overclocking or XMP profile. This will allow them to see some nuances that can not provide the profiles of "V1" and "V2".Also, this mode will be useful to owners of systems based on Intel processors.
• Some changes in procODT + RTT for systems in which 4 RAM SR modules
• Added support for Micron D-die
• Changes in the code that will help speed up the development of the calculator (future versions)
• Added some popup tips for key settings
• New picture in folder Configuring Ryzen Systems v5
• Other corrections/bug fixes
