G'day all I have a stick of DDR333, although it wont work at 333. I have to either underclock it to 266, or overclock it to 350. Weird I know...I have had a lot of grief with it. (SiS648) I was looking at getting some DDR400 or 433 to remove some of the bottleneck with my 533FSB....would it be better for gaming to ----> A) Stick with the 512 DDR350 B) Get 256MB of DDR433 I have my Front side bus speed at 140 which means my CPU is at 2.5ghz. Thanks.
