DDR-RAM Latest news System

Read memory device info (DRAM ICs) of a module? Now it works!

For all those who deal intensively with RAM, the information about the installed memory components aka DRAM ICs of a module is of great importance, as is well known. Now that the second generation of DDR5 ICs will soon reach the market, a simple distinction according to the DRAM manufacturer – Micron, Samsung or Hynix – will no longer be sufficient to draw truly reliable conclusions. Now our friend Martin Malik has made it possible on our request with HWInfo to read out also the DRAM stepping resp. the die revision.

Teardowns of RAM coolers or proprietary motherboard software are no longer necessary (at least most of the time). Below you can find a few examples of how the latest HWinfo beta can already read and decode the information from the SPD of DDR5 modules. Here you can see Hynix 16 Gbit M-Die, Samsung 16 Gbit B-Die and Micron 16 Gbit A-Die. However, a prerequisite for this readout is also that the manufacturer has also stored the corresponding information in the SPD. Unfortunately, there are also modules where the information is simply missing and accordingly only N/A can be output. The only thing that helps here is a teardown or an appeal to the RAM manufacturers to always fill out the list of ingredients of their RAM bars completely and conscientiously.

The download for the latest public beta 7.27 build 4855, which already includes the feature, can be found here:
