Hello! Did I assemble the diagram correctly?

 

Yes, everything looks OK.

Great job! Thanks to god a213m.
I followed your instructions to create a board with all the stuff connected. However, the RW tool can detect my Arduino, but they cannot find the DIMM. Sometimes, the EEPROM is found, but it immediately disconnects. I have checked all the connections and confirmed that they are correct.

Did you build it on a breadboard? Make sure all connections are solid. Sounds like poor connections, especially since EEPROM detection is inconsistent.

SMBus hotfix: 20231214

• Fixed: False RAM type detection

This fixes some RAM being falsely detected as DDR5 due to some RGB controllers being improperly recognized as PMICs.
To use, extract the archive contents into directory where you have SPD-RW 20231210 located, overwriting the old dll file.

problem solved. The RSWP function was enabled by turning on the "SMBus RSWP support" in the settings.
However, a question arises: How does the RSWP clear function work? Can I simply short +9V and SA0 to activate the function?

Second SMBus hotfix in a row: 20231217

SMBus hotfix #2

• Fixed: Errors 0x00000005 (Access is denied) and 0x000001B1 (A device which does not exist was specified), when running multiple instances of SPD-RW

Requires: 20231210 + 20231214
 
With this fix you should be able to run multiple instances of SPD-RW SMBus sessions with no issues.

Major discovery.
 
If your DDR5 is RSWP protected, you can use SPD-RW to clear DDR5 write protection via SMBus on some Asus motherboards.
 

 
To do that, you'll need to install one memory stick into slot A1. Then locate MR_TEST2 header and short its pins with a jumper.
On my Z790 Hero board it is located between ATX power connector and PD_12V_PWR connector:
 

 
Then launch SPD-RW as admin, enable SMBus RSWP support in settings, connect to your SMBus and click Clear RSWP:
 

 
Result:

Hello, does it works?)

Major discovery.
If your DDR5 is RSWP protected

Hello! What about partial protection? Thaiphoon burner killed SPD of my RAM, i have Crucial PRO 64GB Kit, second stick is okay. I just pressed Read, then black screen, this screenshot was taken before. Can i rewrite SPD with your adapter?
