sandy bridge chips don't like bclk you have to use the multiplier for most of the overclocking.

150?!

the most your gonna get is a 7% blck increase so max is usally 107 bro...

sb likes multi overclocking... i barely touch the blck, and if i do it's to lower it so i can clock higher

The new sandy bridge cpus dont overclock like the older cpus. You might be able to up it to 105 but its all in the multiplier.
post #5 of 12
Yeah, you're better off leaving BCLK at 100. Only reason to adjust it is super fine tuning, and even then its usually good around 95-105. Highest I can get is 105.3MHz.

Even if you could overclock via the BCLK, why would you want to on your unlocked 2600K? Defeats the whole purpose getting a CPU with an unlocked multiplier.

Increasing the BCLK simultaneously increases PCI-E BUS, memory, and pretty much everything else. Nasty impact on the IMC, especially. Intel warns overclocking via the BCLK can severely cripple the processor.

not always... sometimes it's the only way to set a divider for higher clocked ram

Not entirely true. I honestly really hate Intel for doing this. I'd rather go back to say the way the 1090T is, or the 955BE. Where you CAN up your reference clock, but you don't HAVE to. The way Intel has done it, we have no choice, since BCLK really can't be adjusted.
