cpu multiplier of pentium e5500

[John Sebastian]

hi
please let me know what is cpu multiplier because my pentium e5500 have a 14x multiplier and set to the max 14,i am overclocked at 3.5ghz and i left the multiplier to 14,my question is what happen if i decrease the multiplier?sorry i am noob about overclocking,does the higher multiplier much better?

2800MHz / 200 actual FSB = 14. Which is the multiplier you reported.

my question is what happen if i decrease the multiplier?

It MIGHT allow you up the FSB even more. 3.5GHz / 14 = 250. This means your FSB is 250MHz actual, 1GHz effective. What motherboard you have plays a big part of what FSB you can hit. If you have a G31 or G41 then you might have already maxed it out. If you have a P35 or P45, then you can probably take it a lot higher. Those boards should be able to hit 400MHz. Your CPU won't support a clock speed of 5.6GHz, so you'd need to drop the multiplier down to 9 or so. Everyone's system is different so you'd need to play around with yours.

so if i wanna go higher clock like 4ghz,i will need to decrease the multiplier to work?

Not quite what I said. 4GHz is 400MHz FSB x 10 CPU multiplier. I'm not sure and kinda doubt your CPU will handle that. And because you haven't listed a motherboard there is no clue at all if your board can do that. You don't have to lower the multiplier. 286 x 14 will also give you 4GHz. As will 333 X 12. What works best depends on the parts you have.

my motherboard is gigabyte ga g41mt es2l,

G41. As above the odds of you hitting 400MHz with that board are slim. You can try 333 x 12. I don't remember how good the 5xxx series was at OCing but I don't remember 4GHz being common.

so the reason why increasing and decreasing the multiplier is to calculate if it is working?
i am sorry, i have so many questions.i am very noob when it comes to overclocking

Not sure what you mean by calculate. The reason why you might change the multiplier is to help you reach your desired frequency. Above I listed 3 ways to hit 4GHz. Lets pretend you have a board that isn't capbable of hitting 400MHz FSB, but you have a monster CPU that can handle it. In this case 333 x 12 is the way you want to go. But lets pretend that you have a great P45 board. 400MHz is no sweet for these boards. By setting it to 400MHz you can drop the CPU down to 10, and should see better power/temp numbers then if you had used 333 x 12. This might help you understand it better.
