hola amigo a213m gracias por la aplicación y mas por su interfaz, comentarte que tuve un problema al tratar de modificar el SPD, debo aclarar
que no uso arduino, para conectar uso el gigabyte madre "GA Z77- D3H",
las memorias que trato de modificar tienen RSWP activado, en la interfaz aparece en gris el botón "CLEAR RSWP", y no puedo hacer click!!
Leí todos los comentarios del hilo y no encontré ninguna información que me ayudara.
También aclaro que pude modificar memorias ram que tienen RSWP deshabilitado y fue todo un acierto.
entonces me pregunto se puede deshabilitar RSWP y asi modificar el SPD solo con arduino?
perdon por mi ingles, espero se entienda mi pregunta...
espero su aporte, muchas gracias.

hello friend a213m thanks for the application and more for its interface, tell you that I had a problem trying to modify the SPD, I must clarify I don't use arduino, to connect I use the mother gigabyte "GA Z77-D3H", The memories that I try to modify have RSWP activated, the "CLEAR RSWP" button appears in gray on the interface, and I cannot click it!! I read all the comments in the thread and couldn't find any information that would help me. I also clarify that I was able to modify ram memories that have RSWP disabled and it was a success. so I wonder can you disable RSWP and thus modify the SPD only with arduino? Sorry for my English, I hope you understand my question... I look forward to your contribution, thank you very much.

I'm sorry, I already changed the language, thanks for the correction

Yes, RSWP functions are only available with Arduino based controllers.

ok thanks for clarifying that doubt.

Wow this awesome! Great work man.

SMBus hotfix: 20230314

• Fixed: Inaccessible SMBus on some systems that don't have device 0 on PCI bus where SMBus controller resides

Just like the last hotfix, this release is marked as pre-release because it contains an updated dll only. To use, extract the archive into directory where you have v.20230205 located, overwriting the old file.

An amazing program, almost the only one of its kind. If you allow me to give you advice, add amd smbus support, it is not write protected, this will cover a huge number of laptops, for example lenovo legions, this will greatly popularize your program. If you need any technical data let me know.

Hi, what AMD platform would you like to see supported? I added AM4 & Threadripper along few other AMD based systems a while back (https://forums.evga.com/FindPost/3557968), but to add new AM5 I need hardware or someone who has such system and is willing to run tests for me.

Hi, as far as I know, at the end of 2021, a huge number of laptops with such a device came out AMD SMBus
INF file oem10.inf INF Section AMDSMBus64
Hardware ID PCI\VEN_1022&DEV_790B&SUBSYS_384217AA&REV_51
Placement information PCI bus 0, device 20, function 0
PCI Device AMD K19.5 FCH - SMBus Controller
 
 
And almost all of them were equipped with memory with incorrect secondary timings, which can be corrected. One of my laptops has exactly the same problem.
 
mainboard chipset Northbridge: 16301022h
Southbridge 790E1022h
SMBUS base address #0 0B00h
base address #1 0000h
SPD on SMBUS at 50h and 52h
 
It will be very cool if you can add support!

I need to see your SMBus controller PCI registers dump.
 
Load CPU-Z with default settings, save report as text file (Tools > Save Report as TXT). Locate "SMBus Controller" section under "PCI Devices" category and post that info.
 
It should look similar to this:
 

 
Paste your info as text, preferably enclosed in [code] or [pre] tags for better readability.
