Which is the right SMBIOS?

Ryzen 3 3200G, AMD Radeon R7 200 Series (Bonarie XTX), 16gb ram, A320M-K, Realtek ALC887, Realtek RTL8186/8111 PCI-E

Followed OpenCore official guide

I succefully installled Catalina on my machine but it's very laggy and I think according to the guide that the problem is that I choose the wrong SMBIOS, that is actually the iMac 18,1.

Please tell me the right SMBIOS cause I can't find nothing searching online and on the guide is not told.
