Hi guys, I have a MacPro 2008 2.8 and am having weird noises from the Ram. I have 2x1GB on the top A riser and 2x4GB on the Bottom riser (not apple). Whilst watching youtube or any sort of streaming video the ram makes noises similar to a cricket. I first thought it was the hard drive seeking but I took that out (1TB WD Caviar Black) and the sound was still there. I then thought it was the GPU. Then I took out my aftermarket RAM and bingo, sound was gone. So does you RAM or RAM in general make any sort of noises? If anyone has any info I would appreciate it before I call up where I brought it and talk about getting a replacement. Thanks guys.
