I have an Intel E6750. This is my first Intel since since a 286 back in 1987 so I have a few questions about how the clocks work.
My motherboard (aBit IP35) BIOS allows you to set the following
External Clock
Multiplier - 6, 7 or 8
DRAM Speed - In the form of a ratio
The spec of the processor is
CPU Speed = 2.66GHz
Bus Speed = 1333MHz
Bus/Core Ratio = 8
This is what I understand
If I set the following
External Clock = 333
Multiplier = 8
DRAM = 1:1.2
Then CPU Speed = 8 x 333 = 2.664GHz
and RAM Speed = 333 x 1.2 x 2 = 799.2MHz
But what determines the Bus Speed - I assume it is 1333MHz - but is it fixed at that or is it some ratio of the External Clock.
My question stems from overclocking
For example if I set the following
External Clock = 350
Multiplier = 8
DRAM = 1:1.2
Then CPU Speed = 2.8GHz and RAM Speed = 840MHz
But what would the FSB be - still 1333Mhz or perhaps 1400MHz?
Cheers,
Nigel
