born1974 Posted December 29, 2005 Posted December 29, 2005 Hello, my question is overclocking... I have an Abit Is7 MoBo sockett 487. A Prescott 3.0E cpu 2 - 512 Mb Kingston 400Mz. Mem sticks running dually (slot1 and slot 3) The only thing iv'e done so far to overclock is raise cpu to run at 3.6Ghz. My Fsb is set to 800Mhz or Hz not sure. My ratio is set to by speed. and my cpu,vga,pci is set to fixed to keep it at 66/33Mhz or Hz not sure witch on is right but the number should tell you. Question, even though everyting but the cpu clock is normal, by raising my cpu speed does my Fsb increase to or does it stay at 800Mhz. because if it does raise than i'm probably running at 950 or so witch would effect my memory too? yes or no? if it does is that what the cpu memory ratio is for? the setting are 1:1 , 3:2 ,5:4 and maybe one other option. I have a water cooled cpu and at 3.6Ghz. my temp only reaches 49 to 53 deg. celcius even after running full boar for 2 hrs. straight. so i think that good there. I just don't want to kill my memory if it overclocks with the cpu. and also i have no idea how to get to the multiplier. Thanx to thoes who respond. good day.

Now what does the 200 number mean, witch is now 240?does that mean 240 x 4 = 960 Fsb? thanx for the reply. and if i'm running at 960 Fsb. should change my memory speed to 5:4 ratio tyo get it back close to 800?Thanx again.

To see if its stable , download a program called "prime95" google that On intel cpus, the fsb is quad pumped, so look at this, 200x15=3000 mhz |200 mhz ram 240x15=3600 mhz |240 mhz ram as for the fsb question, if you lower your fsb you'll be setting a ratio, keep it at 800 for a 1:1 ratio, or set it to 533 for a 5:4 ratio, or set it to 400 for a 1:2 ratio Quote Share this post Link to post Share on other sites More sharing options...
