the msi x99s overclocking is currently failing
My motherboard is an MSI X99S Sli Krait edition. I'm using an Intel 5820K and overclocking it with the XMP profile on my G-Skill F4-3000C15Q-16GB RAM to achieve its intended clock speed of 3000MHz. This overclock raises the CPU from 3.3GHz to 3.6GHz. The processor is capable of speeds above 4.0GHz. Initially, it performed well at 3.6GHz and 3000MHz, but during stress tests at those speeds it only reached 60C. Recently, at 3.3GHz and 2166MHz, it only reaches 45C. It crashes before launching Windows or even entering BIOS, restarting briefly after boot and displaying the message "the overclocking has failed." I have options to reset BIOS settings to defaults or manually adjust them. What causes this issue and how can I resolve it?
With your memory speed at 3000, the bclk should be adjusted to 125 instead of 100. Start with the default settings, then activate the XMP profile for the memory to operate at 3000. If it fails to start, the issue is likely with the memory timings. Next, configure an XMP profile set to 2666 and attempt again. At 2666, the bclk will revert to 100, which should resolve the problem. It seems the issue isn't with your CPU but the memory itself.

Your memory speed is quite high, which affects the bclk setting. Try adjusting everything to the standard values first, then activate the XMP profile for the memory to operate at 3000... if it fails, your memory timings are likely the issue. If you find an XMP profile that runs at 2666, apply that instead. At 2666, the bclk will revert to 100 and should function properly.
I suspect the problem isn't with your CPU but with the memory itself. I was using the 3000mhz XMP profile, which caused it to stop working. It seems the bclk value changed during adjustment—sometimes it shifts from 100 to something else without a clear reason. I experimented with different bclk values, but they didn't correlate with CPU speed changes. For instance, changing it to 150 made the CPU speed jump to 3.7ghz, and vice versa.
I stopped using XMP because only the 3000mhz profile was available. Now I'm running the memory at 2400mhz due to motherboard settings that jump from 2666 to 3200. I realized I needed to change the CPU reference clock to enable overclocking alone. Setting it to 42 gave a stable 4.2ghz, which is great, though I'm disappointed I had to pay extra for this RAM.
It seems there might be no compatible CPU/motherboard pair for the XMP profile. You mentioned 125 bclk instead of 150—maybe trying 3000mhz/125 could work. I'll test that now.
