it changes every thing on the motherboard not just the cpu (so higher temps, more changes = more likely to crash)

 

also stress things that aren't really meant to be OC

Everything  can break from being out of sync.

pretty much and gpu clocks will nopt be stable anymore

Please follow your topics guys, it's very important! CoC F.A.Q  Please use the corresponding PC part picker link for your country USA, UK, Canada, Australia, Spain, Italy, New Zealand and Germany

also if you find anyone with this handle in games its most likely me so say hi

well i was thinking of just overclocking my current cpu by 200mhz to make it 3ghz but i just didn't want anything bad happening so i wanted to make sure it was safe or not

1 extra bclk mhz wont do that much so just keep it resonable

I wouldn't try that. Your system will quickly become unstable.

RAM, CPU, and PCIe timings will all change.

so 200mhz extra is fine?

Ocing on the BLK as people have said will increase everything. PCI-E are meant to run at 100hz nothing more or less. If you start to mess around with that (due to BLK) you may do some damage/make them unstable.

Well I got 109 from my Z77 platform with a G860.

 

Issue is you risk data corruption etc as it throws a lot of the platform out of whack.

ok i just thought that if it was safe enough i might as well do a light overclock

most pcie lanes have been fixed at 100mhz for about 6 or more years now.

I experimented with BCLK overclocking twice trying to aim for a +100 MHz increase on the CPU, both times something went horribly wrong.

 

Attempt #1: Bumped up BCLK from 100 to 103.5 MHz for a 100MHz CPU overclock, dropped RAM frequency from 1866 to 1600 MHz. Neglected to undo my previous CPU undervolt (-60 mV core, -160 mV cache), and my system refused to POST.

Attempt #2: Limited BCLK increase to 103 MHz, lowered RAM frequency to 1600 MHz, and used stock CPU voltages. System posted, but my second display refused to extend my desktop and duplicated the first display instead. Windows Aero refused to function properly, and everything was glitchy overall.

 

Overall, it seems the costs of instability from BCLK overclocking far outweigh the limited benefits.
