MSI 990XA-GD55 low FSB

post #1 of 2
Thread Starter 
I just purchased a brand spanking new 8120 and I'm loving it right now. I've been steadily OC'ing it and have gotten it to 4.5 Only with the multiplier. I wanted to do it with my FSB but it will only go up to 225, after that it stops posting. I keep everything close to stock as i pump it up but if i go up to 226 and keep everything low it doesnt post. I thought that was fine and didnt worry about it till i saw people hitting 250+ in their bios. is it my board thats bad or am i doing something. I also cant up my voltage on my cpu past 1.4v which puts me at the 4.5 with a core temp of 50 running prime95.

when you raise the FBS it incresses all your settings the ram speed your NB frequancy and your HT link frequancy as well as cpu speed so when you set FBS at to 250 you have to set your multipyer your ram speed and NB frequancy as well as your HT link frequancy with in a range your cpu can run at as well as voltage settings this guilde will help with over clocking with FBS
