I had someone bring over their computer some small shop built for him because it was shutting down. Turns out it was the Tiger power supply fan stopped working. But when I opened it up I noticed they had installed 8 gig of OEM Crucial CT25664BA1339 ram (4-2gigs) in a triple MSI X58M motherboard. His daughters use the computer and I don't think they need 8 gigs but wondered if 6 gigs in tri-channel would be better then the 8 gigs now working in dual-channel? Thanks for any help.
