Does BCLK do anything positive besides the negative of higher temps

[Turtle Rig]

What is the point of raising the QPI Link ?  Benchmarks show same results.  Raising BCLK I heard stresses your whole system and makes things run hotter.  So wtf is the point of BCLK ?  No performance improvement then just tinkering with the Multi ratio.  I once put it to 135 or 140 and it was using 120 watts extra power on idle.. and about 200watts more then a 100 BCLK.  Any insight would be great.

50x multiplier + 1.03 BCLK gives you a 150mhz boost. How did you manage to have 140 BCLK stable?

Well

Well my multi is 38x or I took it down to 37x don't remember,,,, I bet it was not stable and things get really hot,, your vrm and everything.  I mean wtf is it for ?

Most likely the base strap was 133, then OCed from there.

 

Baseclock is just what the CPU would run at without a multiplier. You can overclock baseclock in the same way you overclock the multiplier, and get higher frequencies.

I didn't even strap it, I just took it from like 120 to 145 and all I remember was my wattage usage went from avg 120 to 240watts then I took it back down to 119 and all was well. sighs

Base clock is just that.... the base clock. Most of the other frequencies around the board are based on that. 

 

PCIe frequency, CPU frequency, memory frequency, etc. Increasing BCLK without decreasing other things (like PCIe frequency and memory frequency) will likely cause instability extremely quickly. 

 

Increasing BCLK is how we overclocked before the multipliers were available. 

 

It's also how you overclock non-unlocked chips.

I understand..,,,,, Best to leave it at stock why put pressure on the entire system like that for no reason at all.

If you have an unlocked chip, sure, I agree with you.

 

But if you want to buy a cheaper locked chip and take your chance overclocking that way, then you used to be able to do that. Now, I believe, locked chips also lock the base clock to like +-5% or something. At least that's what I read on the forums here. 

 

For example. I have a couple of LGA 775 boards. One of them contains a Intel extreme edition chip that costed $1000 new. It is obviously unlocked so I can change the multiplier. I bought it for $100. My other LGA 775 system contains a chip that was MUCH cheaper new. I bought it for $10. I cannot change the multiplier, but using the base clock I have overclocked it to the same speed as the extreme edition chip.

PCIe frequency

Are you sure PCIe still linked to base clock? Or am I mistaken.

It depends on the chipset/board. High end boards typically unlink them. Low end boards typically have them linked.
