MSI DEBUG LED

[Kok0ro]

Hey guys i'm new to this forum but been always a fan of the show on youtube so i decided to join in.

The problem is: I have a MSI Z170A gaming pro carbon Mobo and it has some debugging leds on board. CPU - DRAM - VGA meaning that when they turn on that specific component is preventing the pc to post.

Knowing that i have the VGA led on BUT when i overclock the CPU... wth? right?! i have a 6400 i5 non k overclocked to 4.13ghz already and a msi gtx 1060 gaming X oc'd to 2.1ghz and it runs just fine like that. But the non k overclock could go much hihger i have seen ppl using clocks like 4.7 with just 1.35 volts. So, if i overclock further it just doesnt boot and turns on the VGA led...  My cooling solution it's the AIO enermax Liqtech II 240 so i think the problem its not there, could some1 help me understanding this? Thanks in advance!

This is due to your BCLK being too high, and the pcie bus which also relies on the BCLK frequency is refusing too work at that high of a frequency which causes the gpu to not work.

 

Really nothing you can do about it.

but bclk doesnt influence pcie anymore in skylake
