We'd need to know what the difference between "forget/forgot/have forgotten a name" actually is.
It seems there isn't really an unequivocal answer:

Hm. That does seem very confusing. Let's wait what CK says.

I assume all of these past tense translations are probably OK.

While I wouldn't link these following English sentences directly to "I forget his name", they can often be used interchangeably.

eng
I forgot his name.
eng
I've forgotten his name.

Woud this also mean "I tend to forget his name"?
