Solve : CPU FSB help?

Answer»

I have read on the NET that the Computers Front/side BUSS is just the speed of the Motherboard and how fast the Data GETS from say the RAM to the CPU and Data gets to the CPU and to the PCI slots.

I get this.

And the CPU speed is just how many instructions the CPU can do in a Cycle  and my CPU is 3GHz  so that mean my CPU is doing 3 Billion Instructions per sec I get this.

So when people say they Overclock there CPU  what they mean is hey overclock the Motherboard Speed right???

And if you have a CPU that runs at a speed of 3GHz and your Motherboard runs at a speed of 533 MGz then this means your Motherboard is slower then the CPU.

So when your CPU came up with the Instruction it just prossesed  it has to sit  and weight till the Motherboard comes to get the Data and pass it on.

So the is why people Overclock the Motherboard Right? Quote from: nymph4 on March 31, 2008, 01:32:16 PM

Honestly, why do you still delete your previous threads? Like I've told you before it is extremely annoying and selfish.
It is annoying because if you hadn't deleted your previous thread on basically the same topic, I could have quoted my self SAYING that a processor can do more than 1 instruction per clock cycle instead of having to write it again. And it is selfish because now other users can't benefit from your questions.

Actually I don't really feel like answering your questions anymore.
UPDATE:
Issue sorted and no hard feelings (for my part at least). Quote from: Deerpark on March 31, 2008, 02:52:16 PM

PROCESSORS do more than 1 instruction per clock cycle.

No.
Let me clarify a few things.
It is correct that the internal speed of processors is a lot higher than what you can send/RECEIVE from the RAM.
(I believe the FSB on the fastest motherboards today is 1600 MHz.)
But simply knowing the clock rate of the FSB doesn't really tell you much about how much data can pass between the hardware components. Because the motherboard may have SEVERAL channels it can send and receive on at the same time. So in one clock tick it may be sending data on multiple channels at once.

And the processor often perform more than one instruction on a piece of data before returning it to the RAM. It may take several clock ticks to get the finished result.
The processors actually have its own memory called the cache that it uses to store data while it is being processed. The cache is a lot faster than main memory.

So you can get a performance gain by increasing the internal clock rate of the processor. But increasing the FSB also boosts performance.
