Yes my memory right now is at 280mhz "it shows that in the bios and Sandra" because I have the host/dram ratio at 2.0 , however when I set it at 2.66 in the bios it shows it at 373mhz in the bios the reason I won't check it at that ratio in Sandra is because I only have pc 2100 and 373 is to far out of spec for pc2100 however I did check it once in Sandra at 134 fsb and ratio at 2.66 { 3:4} and it showed it at 356mhz and my memory scores in Sandra memory were 2684/2568 , when I changed it to 2.0 {1:1} the scores in Sandra memory were in the 1900's, this leads me to believe it does have the 3:4 ratio at above 133fsb, until I get some pc2700 or higher I can't test it out at 140 fsb at 2.66 {3:4}, your thoughts please.
