DRAM Calculator for Ryzen

DRAM Calculator for Ryzen is a utility used as an aid in overclocking RAM on computers equipped with Ryzen processors from AMD. The program itself changes no operating parameters of the installed RAM sticks. The interface is in English, but there are tooltips in Russian. Supported by operating systems Windows 7 and higher.

  5. Wait for the system to complete the installation process.
  6. That’s it!

Main features of DRAM Calculator

  • Modes are provided that allow you to test Easy, Defo and Custom Mod.
  • Current timings are quickly calculated and recommendations for settings are provided.
  • Availability of built-in presets for various types of memory (Mikron, Samsung and others).
  • Provides information regarding latency measurements in chart format (the graph displays latency time).

Using DRAM Calculator

To calculate timings, the user needs to fill in 18 fields:
  1. “Processor”. Selecting the Ryzen processor generation. Here are the processors that are supported by the DRAM Calculator for Ryzen (the list will expand over time).
  2. “Memory Type”. Selecting the type of memory (manufacturer and the memory chips he used to build the RAM module). The same as in the previous case.
  3. “DRAM PCB revision”. Revision of the memory PCB or, more simply, the design of the printed circuit board. The PCB revision is determined by the way the memory chips are located on the RAM module and other design features.
  4. “Memory Rank”. There are only 2 options here – single- or dual-rank memory.
  5. “Frequency (MT/s)”. Peak (maximum) operating frequency of memory. You should look in the technical documentation for the RAM module.
  6. “BCLK (100-104.8)”. Base frequency of the motherboard. You should look in the technical documentation for the motherboard.
  7. “DIMM Modules”. Number of RAM modules installed in the motherboard (1, 2 or 4). Here we are talking about the actual number of RAM sticks, and not about the number of connectors on the motherboard for their installation.
  8. “Motherboard”. Motherboard topology type. Also described in the documentation for the board.
  9. Starting from “tCL (CAS) ns” and ending with “tFAW ns” – 10 fields in which you need to enter the current RAM timings. Timing values can be determined using special utilities.
After filling out all the required fields, all you have to do is click on one of the buttons:
  • “Calculate SAFE”. The program will display timings, voltage values and other parameters, the setting of which is safe for RAM operation.
  • “Calculate FAST”. Values of timings and other parameters for overclocking RAM to the highest possible performance. Such timings should be set with caution, because… they can cause the RAM modules to overheat. It doesn’t hurt to organize additional ventilation for them (even if the module design has a cooling radiator).
The last step is to set the timing values obtained in the program in the BIOS. This is a completely different topic. Here we can add that entering incorrect values will result in the computer refusing to start (it will simply turn off immediately after turning on). Fortunately, BIOS settings can always be reset manually, which will also reset the timings to factory defaults.

DRAM Calculator

v1.7.3

  • Some correction for Micron E-die and Hynix CJR/DJR presets
  • Bug fixes

v1.7.2

  • Support OC assist for Micron E-die (A2) and CJR/DJR (A0 and A2)
  • Some correction for OC assist (Samsung B-die)
  • Additional presets for Hynix CJR / DJR (now A0 and A2)
  • Error fix: “Parse data”
  • Minor fix: voltage for Samsung B-die
  • Minor fix: some timings for Micron E-die
  • Minor fix: tWRRD for 4 DIMM configuration
  • Other bug fixes

v1.7.1

  • Reworking of all presets for Samsung b-die, Micron e-die and Hynix CJR (DJR). Improved support for configurations with 4 or 8 RAM modules.
  • R-XMP and Calculate EXTREME buttons removed.
  • Added new Help and my reviews section, which provides links to my materials in addition to reference information.
  • DRAM PCB Revision – select PCB RAM for more accurate calculation of timings. In most cases it is recommended to use “A0” for better compatibility.
  • The “Compare timings (ON/OFF)” button has received updated functionality. It can read not only the timings, but also show the state of the timings in color. Your personal assistant for creating individual presets.
  • Added “New version?” button, which allows you to visit the product homepage and read the materials regarding DRAM Calculator for Ryzen, check for updates or ask any question.
  • Error fixes and some graphical adjustments.
  • Timings read support for all Ryzen family processors (including future Zen 3 processors).

v1.7.0

I believe that there should be a utility that provides the user with all important memory benchmarking tools, so this release was aimed exactly at that.

Updating the memory presets is planned in version 1.7.1.

  • Added functionality to read current memory timings for Zen 2 (AM4).
  • Added a memory bandwidth test (Read and Write).
  • Added an Inter-Core Latency test (AM4).
  • Improved the accuracy of Random and Custom latency test.
  • Some changes in the suggested CAD_BUS settings. This could offer a significant improvement in stability for configurations with two or more RAM modules.
  • VDDG setting is now divided into two independent settings: VDDG IOD and VDDG CCD voltage (as in AGESA 1004B bioses).
  • “Compare timings” now works for Zen 2 (AM4).
  • Added support for 3000 series Threadripper CPUs (Castle Peak).
  • Minor user experience GUI changes.
  • Added support for Hynix DJR (a new CJR revision that has backward compatibility with classic CJR).
  • Minor bugfixes
