Adjusted the BCLK setting on my 6600K but the PC still won't start.
I recently assembled my PC and immediately attempted an overclock. It stabilized at 4.6Ghz with a voltage of 1.415v and a temperature of 61°C at its peak. I experimented with adjusting the base clock, doubled the BCLK and halved the multiplier on my CPU, modified the RAM speed, and left everything else unchanged (voltage as previously noted). I did not alter any other settings. After restarting, it failed to boot. I cleared the CMOS, unplugged and plugged it back in, used a multimeter for testing.
My concern is whether running a high clock with low voltage could harm the motherboard or CPU. These are the only parts I'm worried about. The maximum Skylake voltage is 1.6v before the warranty expires, so I was within safe limits there. My initial thought was that the CPU might fail first, given the poor quality of the motherboard (MSI Z170 Krait with bad VDROOP and no features) and its LEDs lighting up when powered on. However, after some research, I believe a more probable cause is the motherboard overheating. It has three debug LEDs, and while the CPU LED stays on constantly, the indicators for RAM or VGA don’t light up when nothing is installed. When I install just one RAM stick regardless of slot or type, both the RAM and CPU LEDs flicker, but eventually only the CPU lights up. The VGA remains off even when I insert or remove cards. All capacitors and connectors show charge and conductivity, so the CPU should be receiving power. Could the high frequency have damaged the chipset? I’m not sure, that’s why I’m reaching out.
Thank you in advance.
CPUs differ in the BCLK they support. Some operate at higher frequencies, while others are more limited. Today, BCLK adjustments are mostly focused on locked CPUs using the newest UEFIs that support overclocking. For K series chips with unlocked multipliers, modifying BCLK isn't necessary unless you're adjusting DRAM speeds. Also, remember your Uncore speed setting during this process? And the 1.6v reading seems unusually high—did you find it in a specific source? I'm observing a maximum of 1.45, which still appears quite high.
