Is it true that MBs with DDR3 like GIGABYTE EP43C-DS3 have problems with Bios?
No, but where did you read that?
Just heard from a friend, nothing to get worried about, I guess.
If it was true, then all sytems using a Core i7 or Xeon 5500 series CPU would have BIOS issues since they all require DDR3 memory.
