I am writing this as a conclusion for those who search for this because there motherboard does the same thing. There appears to be a design flaw in this motherboard that causes a high pitched squeal when the memory is volted to 2.2v. In there bois, it is listed as being overvolted by .4v. The problem wasn’t the motherboard being too tight as I had thought. I wasted much time trying different settings on the board. I even had the board out of the case and holding it to verify it wasn’t shorting out on anything. After 2 RMA’d boards, I gave up. Bottom line, don’t use this board with 2.2V memory unless you are deaf to high frequency sounds. I bought the Abit AW9D-MAX 975X instead and have had no problems. Please leave a comment if this post helps or if you have had a similar issue.
