4670k OC'ing

[sandals100]

So I was FINALLY able to get my shitty ass 4670k over the 4.1ghz I have been sitting at for months now. I was sucessfully able to OC to 4.25ghz with 1.305volts. To get this OC I had to change the BLCK frequency to 101.16MHZ, the problem is I have no clue what the hell it is, the second I try and increase it even the slightest bit more I have a BSOD. Could someone please properly explain to me what this is and what other components (other than the ram) is affected.

You should probably leave BLCK alone and just use the multiplier. As for BSOD, you may have just hit the limits for what your CPU can do.

Could you explain why I shouldn't touch it? Thank you!

Well, the main reason is that just using the multiplier is much easier. The BLCK changes the CPU's base clock, it can also change the speed of PCIe as well, but I think that was only on Sandy Bridge. 

 

Using the multiplier often yields higher clocks. The only time using the BLCK is 'better' is for locked CPUs as it's really the only way to increase the clockspeed on a non K CPU.
