Hello, my question is quite simple. I know Intel turbo boost will normally overclock your multiplier when u need it. but can it overclock ur Blck to? can u turn on something or ajust it manually so when your turbo boost start that ovc your bclk to? thanks.

If this is with Sandy Bridge, Ivy Bridge, or Haswell, then you can overclock the BCLK, but it's not recommended at all unless you require it to get over a hurdle. For example, let's say you can achieve 4.9 GHz with 100 x 49, but 100 x 50 just doesn't work no matter what you do. This is where BCLK overclocking comes in. Change the BCLK to 102 for 102 x 49 and you get 4998 MHz. Change it to 102.1 MHz for 102.1 x 49 and you get 5002.9 MHz. ;)

I'm not sure what you're asking, so I will have to leave this for someone who does.

AFAIK, turbo boost just increases the multiplier on demand up to the stablished limit. If you raise your BLCK without disabling turbo boost, your system will become pretty unstable.

Set a locked multiplier without turbo boost, and then raise a little the BLCK, till it becomes unstable.

By the way, as all the people in here already notticed you, it is NOT recommended to overclock using BLCK instead of multiplier.

No, I'm saying that it's not recommended to overclock the BCLK at all. Period. That is, unless it's absolutely necessary. Fortunately, it doesn't need to be much more than a 1-3 MHz increase. Again, for example, if you wanted to go from 4.9 GHz (100 x 49) to 5.0 GHz (100 x 50), but you just can't do it no matter what you try. This is where overclocking the BCLK comes into play. All you need to do is set it to 102.1 x 49, and you get 5002.9 MHz. However, I would only do this on higher-end motherboards myself...

In the end, what I think he needs to know is a way to make a game he plays to run faster, as he asked for this in several posts. He states that the game is badly coded, what makes me think that is affected un some way by the BLCK (it reminds me of old 286 games that went crazy fast on my 66mhz 486DX2).
So, maybe all he needs is to raise a little BLCK, without raising the system clock at all, I mean, to compensate the speed by lowering the multiplyer.

I'm just guessing...

I guess he wants to know if its possible to configure the turboboost so that it does not only raise the multi when active, but also the bclk, which is afaik impossible.
post #9 of 9

Yeah, you're right Athon. It's impossible. The BCLK is like the FSB, but it's also the PCI-E Frequency.

 

If he's having gaming performance, then it could be one of many things. It could be some component in his rig holding him back, or it could be that he has an extremely low quality PSU that's delivering very unstable power, or it could be an overheating issue... it's hard to diagnose between multiple threads that are all trying to achieve the same goal.
