DDR5 Mode Register Read

HRuck — Sun, 04 Feb 2024 18:04:25 GMT

Hello,

I am searching for a solution to do a DDR5 Mode Register Read on intel plattforms (Embedded processors preferred, but Server would also be a starting point). I have no idea about software, so i asked Chat GPT and it mentioned that this would be possible with IPP and Python. This lead me to this site and maybe somebody can give me some hint how to do this.

So if you would have a "out of the box" solution, this would be nice, but I do not expect this and would be happy just if I could get a hint where to start.

Maybe some server vendors have a solution, maybe some open source is available to do this.

So any hint and help is highly appreciated!

Thanks a lot!

for Servers I could add and clarify my needs:

e. g. trying to get the information out of the DRAM what the DRAM internal ECC mechanism documente (so not the Controller external ECC) is stored in the Mode Registers, so a MRR (Mode Register Read) is required.

Same if you want to get the training/configuration result out of the DRAM for Vref(CA/DQ) and DFE equalizer settings. Both are trained during power up and the result is stored in the Mode Register and can be retrieved with a MRR.

For Post package repair there are MRW (ModeRegister Write) and Mode Register Read needed.

All of these are functions that require to send Mode Register Write/Read and this is want I want to achieve..

Thanks for any information.

Hello,

I do have the request for both Server (thats the reason why it was moved to this part) and Embedded.

I see much more chances to start with a server, so please do not close this, but leave it open to find a solution on server.

I wanted to do one step after the other, but after your comment i will ask the same question on the embedded side. Thanks for the link.

Please check if you find any hint for server based Systems.

thanks a lot!

am confused .. on top of this page there is mentioned this is a forum for server products.

So it seems, that for any server related platform this is the correct forum.

So why redirecting this request to an embedded forum?
