Marking on MOBO is evidently wrong. Acording to

Marking on MOBO is evidently wrong. Acording to Gigabyte website it is GA-8IPE1000 Pro-G dual ROM.
I had problem with sound and I tried to solve it by flashing BIOS- it didn`t help:(
Then I changed ALC650 and there was sound:)
So, main problem with MOBO was burned Firewire chip and bad ALC650.
