Higher Clock vs Higher Bclk

Does having one higher then the other but keeping the same overall frequency make a difference?

A higher Bclk will be faster. But could limit your overclock.

Will it be any hotter?

The heat is more determined by the voltage you put into it but usually from my experience a higher Bclk will need more voltage to maintain stability.

I see, thank you

Just thought of something else, you said a higher blck would be faster but does that mean

a 17*210 (3.57 Ghz)

would be faster then

a 21*195 (3.9 Ghz)

Sorry to intervene, but i believe that it depends on the application. A higher Bclk would be better if the application was bandwidth hungry, but since most CPUs today are fed quite well by the bus a higher clock speed would usually be faster for most applications and games.

Correct me if i am wrong.

Now if both overclocks were the same speed of 3.57 with 1 14*255 and the other 10*357 the 357 would be the faster overclock all around.

^ Agree here. Increasing the bus speed and lowering the multiplier is an old left over trick from days gone by when bus speeds were a lot slower than they are today. With the quad pumped bus's today, the bus is not the bottleneck it used to be.

What does 'blck' standfor? Obviously it is the clock multiplier, but I have never come across that term.

base clock I think
March 19, 2010 10:11:40 AM

It means Base Clock, and the higher you go, the more voltage comes to play in maintaining stability... For instance, when overclocking my I7920, after 4.2 ghz, i need to start up my voltage a tad bit... A higher bus speed is always faster that a higher multiplier for the same overclock, like everyone has already mentioned... Good job guys...

Actually bclk is just a reference. You can up your memory, qpi, uncore and cpu by upping the multipliers without upping the bclk and end up with the same results.
The problem is that unless you have an extreme edition cpu you can't raise the cpu multi so to get the cpu speed you have to raise the bclk on the non EE cpu's.

You just can't make a blanket statement that at a given cpu speed a higher bclk will perform better than a lower one. I depends on how fast everything else is running.

Bclk is not the same as fsb and the same rules don't apply.
