What actually happens when you've got other than 1 : 1 FSB ratio? As I understand it, that would produce some empty clocks in the system and reduce the overall preformance. So, is it better to put the FSB 1 : 1 at highest possible speed, or to force max FSB speed but with a multiplier as my memmory just can't take any higher? I've tried with 5 : 4 and the moment Windows logged on I got and error msg!
I was trying to figure that 1 out too. with 1:1 i could only hit 3.3 ghz stable (crappy memory) and with 5:4 i can hit 3.6 ghz. With the 3.6 ghz i noticed a performance boost in games so go for the 5:4. I also want to know excactly what the difference is....so any1?
The faster your memory is running, the more memory bandwidth you have. For example: CPU Multi x HTT = Clockspeed 9 x 250 = 2250MHz 10 x 225 = 2250MHz --------- 9 x 250 is faster (if both are not running some kind of divider). It is not easy to explain quickly, so I will use an example: If you have found through experimentation that your memory can run up to 220MHz stable, and your CPU Multiplier is 10, then you can use a divider to pass 2200MHz with your memory still maxed out. By using the 166MHz divider, you can now reach up to 2640MHz with your memory still maxed out at 220MHz. The best overclockers will make good use of higher memory clocks as well as high clock frequencies to increase performance. Edit: My examples are for AMD CPUs, but the general principle is the same for Intel.
1:1 on my sytsem is better then my 4:3. I can only run 4:3 under 4ghz. Over 4ghz my cheap memory is to slow and i must switch to 1:1.
