Hi

I've noticed that a lot of people using 1155 platform and i5 and i7 cpus only go higher on multiplier. Seldom people push fsb and if they do maximum i've seen here is 105mhz...

To my understanding if you make the fsb wider (100mhz +) then more data can go through faster. Just like wider road. Multiplier is just increasing speed limit so more cars can go through.

Please enlighten me on this.

Thanks

Eric

The 100MHz is NOT FSB clock, it is BCLK. B=BOARD (I think). Basically, (nearly??) every clock on the board is derived from this one clock. Pushing that means you push all clocks accordingly which is just a recipe for instability IMHO.

The memory bus can be overclocked independently from the CPU BTW....
 
Basically, it's the clock generator which all the pieces of hardware run off so they all run in sync. I think it also controls things like the SATA clock and things like that which do NOT like running higher than spec and does not give you any kind of gains. This is similar to some mobos that you have to fix the PCI speed to 100MHz to avoid instability.

The X79 boards have a multiplier which acts to multiply the blck value for the CPU only, so the CPU 'sees' a higher BLCK and hence increases it's frequency.

Back in the FSB days what your saying is kinda true but today it is not.

It's irrelevant anyway, you can't raise the blck much (if at all).
