to AK12A interesuje mnie agp pisze ze na x4 przy 3.3v

tak jest sprawna wymieniłem jej kondy dziś troche segregowałem i znalazłem ja

Supports separately powered 3.3V (5V tolerant) interface to system memory, AGP, and PCI bus

wychodzi na to ze płyta ma na agp 3.3v

zmierzę miernikiem będzie wiarygodniej chciałbym schemat ideowy portu AGP
