I have my x2 setup, and at first i didnt want to OC so i stuck with 2gigs DDR400. Memory clock is 200mhz and my clock is 200mhz (400mhz FSB). If i start upping the FSB, wont my memory be pushed too much? Even if i mess with the HT ratio and move it to 4x or adjust other things my HTT rises above 1000
At 200mhz system clock speed with a multi of 10 and DDR400 Im running at 2ghz with the memory being syncronous at 200mhz right? If i up the FSB the memory clock goes up too ... meaning itd run over its 200mhz ratings?
250 FSB
10x multi
DDR400
Mem Ratio: 5/6 (DDR333 settings)
CPU Speed: 2500mhz
HTT: 1500
Divider: 12
Mem clock: 208
Arent those figures correct? I think i forgot to incorporate the 5x to 4x thing didnt i ... where does that fall into the algorithm? heres a php page i made ... which i need to fix i guess
