8700k clock speed boost. 100.5Mhz bus rate at 100Mhz setting in BIOS.
8700k clock speed boost. 100.5Mhz bus rate at 100Mhz setting in BIOS.
I have an 8700k paired with an MSI Godlike gaming MB.
Setting BIOS to x50 with a base of 100Mhz.
XMP enabled using G.skill 3200Mhz 32GB RAM.
Noctua Nh-d14 cooler is installed.
When I boot into Windows it's set to 100.5, which is making the CPU more voltage-hungry.
It's stable with the current configuration at 1.320 CPU voltage, but it generates a fair amount of heat.
However, after using the Windows-based OC program to adjust it to 100Mhz, it became stable at least at 1.290 voltage. Still, I can't consistently lock it at 100Mhz, and I've tried uninstalling every OC program and updating the BIOS on my motherboard.
All attempts have failed, and every time I open Windows it's set to 100.5.
I also tried disabling XMP, but it doesn't stay at 100Mhz for any reason.
Boards simply adjust that. The 100 MHz is the target frequency. My Z77 operates at 100.08 MHz BCLK, unless I shift it to 99.8 or 100.16 MHz, and I've heard of several MSI boards that run slightly below standard 100 MHz.
Your board varies by 0.5%, which falls comfortably within the "spread spectrum" range introduced earlier (like in Pentium 4), designed to reduce electromagnetic emissions from today's computers.
Adjust it to 99.5Mhz, keep in mind there are always some fluctuations.

That's correct, the motherboard fluctuations are typical based on what I've seen in reviews. For instance, my model has a rating of 99.99.
