The DRAM Calculator is a handy tool that will help you make it easier to overclock the memory on Ryzen based systems. It suggests memory timing sets optimized for your memory kit, for example B-die.

The end result is that by using the Ryzen DRAM calculator you can achieve higher memory overclocks with better stability. Ryzen DRAM calculator is designed to work with all Zen and Zen 2 architecture processors, first, second and third generation Ryzen.

What's New:

  • NEW. Memory status. Information about the available memory.
  • NEW. CAD_BUS received very flexible settings. Thanks to these flexible settings, it is possible to disable GDM (1T mode) without losing stability for Zen 2. DR also got the opportunity to disable GDM at low frequencies (up to 3200 MHz inclusive). Compatibility with previous generations is required to be tested.
  • Updated function to determine the maximum available memory for testing (Memtest mode). At the moment, the test should not go into drives or a swap file.
  • tRDWR has been changed in most profiles, this is a bonus to the chance to get a stable system.
  • Most presets received small changes, in particular Micron e-die .
  • Improved support for 4 modules.
  • Bug fixes.
  • The maximum frequency for 1:1 mode is now 3800 MHz, and for 2:1 mode - 4200.
  • Updated presets for Samsung b-die, Hynix CJR and Micron e-die.
  • Added backward compatibility of Zen 2 with previous generations of motherboards.
  • Added PMU Training recommendations for all Ryzen platforms. Better training - a more stable system.
  • Added autosave of the main tab settings when closing the program and automatically loading them when the program is started.
  • Improved tWRRD prediction for Dual Rank.
  • Color notification of voltage limits and FCLK. Black is the norm, red is the limit.
  • Timing detection for Zen and Zen+ generations. For the generation Zen 2 at the moment there is no possibility to add a definition of timings due to NDA. Unfortunately.
  • Fixed a lack of presets for X399.
  • Fixed a rare error in which it was impossible to calculate the timings.
  • Added a button to access the Internet overclocking statistics generation Zen 2.
  • For users of Intel systems in the "Additional Calculators" section, it is possible to calculate tREFI and RTL IO-L.
  • Added 2 new latency tests for MEMbench.
  • Custom latency is a memory access test that the processor cannot predict (using a specific offset).
  • Random latency - the average time is measured for random memory accesses in a buffer of a certain size. Partially affects the result of TLB.
  • Both tests are release candidates, but I do not deny that there will be calibrations.
  • Custom latency and Random latency are included in the Easy and Default packages. Please note that during testing, the program will open / close the prompt itself (you do not need to deal with it).
  • Added information about the processor's L3 cache size. Also, the size of the test blocks for latency tests is controlled relative to it.
  • Added button Clear standby. It is used to clean cached memory by the operating system. Didn't the test run? - Click Clear standby.
  • Max RAM button better determines the amount of free memory available for testing. Useful for checking memory for errors.
  • There are exceptions for many functions.
  • Fault tolerance of the program increased.
  • Graphics updated
