I want to test my second Yamaha 744 with my i865 machine, where other Yamaha 744 worked, i got strange error boot that legacy audio is disable.. I tried to load setup utility, but i get message that there not Yamaha chip card inserted (Cant find Yamaha DS-XG). When started it realmode without driver utility can be executed.. (but i dont know if it is big deal). That second card, worked fine with VIA 880 Ultra (with exactly same driver, i just copied it not change anything in ini or setup utility) only disadvantages was some crackling in some games and worse compatibility - but i though (and thing) that was "just compatibility think", i double checked if its right in slot..
After that i tried my first Yamaha 744, first already worked with this machine, with exactly same settings and its working fine, in exactly same slot.
- If didnt killed my second Yamaha 744 (in process i assume that i didnt).
a) My second card is half dead, i had 3rd card some same Polish source, which not worked even with Via 880 ultra, i dont have it now at this location, i thought that i could be problem with slot contact, but my testbench sucks - cards is 1-2mm higher than it should be.
b) There is some difference between cards, maybe some firmware etc. I looked at chips there is slight difference in not working has (Yamaha744B-R), working one has (744-V). True is that second card was cheap, it is a bit paranoic, but i would be totrally surprised if someone would try to sell some half that RMA cards, because seller had lots of them.
I looked into datasheet:
only difference i found is this:
YMF744B-V : 0.5mm pin pitch
YMF744B-R : 0.4mm pin pitch
Working one, its looks more deluxe, has digital output, it was advertised as Aopen one:
NonWorking one - regarding of A logo is Abit or Aopen too:
