Your motherboard is an ASUS Z170-P, and the CPU is an E3 1220V5 that works in modified BIOS. You've tested several BIOS versions, but the CPU always runs at 100MHz BLCK. What should you do next?

Could you clarify if you need assistance with something specific?

Based on previous experiences, single-digit improvements are advised. A 120Mhz frequency appears too high. Please revert to the updated BIOS and verify that the changes are functioning properly in CPUZ.

Are you attempting to boost your CPU speed with the BLCK setting? As mentioned, it's generally safer to raise BLCK in 1Mhz steps. You might be encountering problems because your motherboard, chipset, or BIOS doesn't fully support Xeon CPUs—so a custom BIOS might be causing further complications.

Would you like me to display the images for the bios settings and cpuz?

Skylake BCLK OC offers more flexibility as the BCLK is now independent from PCIe speed and other parameters, effectively eliminating any concerns about increasing it. The PCIe frequency remains dependent on your SSD's specifications. While newer BIOS versions have improved support, some earlier ones still allow BCLK OC on non-K CPUs. You can find relevant ASUS BIOS updates here; however, there appears to be no official support for the Z170P model, so you may need to flash a Z170A. This process is straightforward with a CH341A tool and any compatible object for removing the BIOS chip. The risk is minimal due to the simple nature of the reflashing. Personally, I use a P5QD Turbo BIOS on my P5Q for optimal FSB OC performance without any issues. The chip notch must face the back, and for software, I rely on AsProgrammer—simply locate the chip text, flash it, and back up your current BIOS by reading and saving the chip data.

I also attempted to boost it by 1mhz, but it didn<|pad|>, so it didn’t work.

It starts with the standard BCLK frequency. I suspect the EUFI firmware isn't configured correctly due to a setting conflict. Since you don’t own an ASUS Z-series board, check if there was a "BCLK locked on" option in the advanced CPU settings. Disable that and other similar features. Overclocking to 120MHz is unlikely unless you have a very high-end board with an IGPU or specific hardware. If you’re using an SSD, skip XMP/mvMega settings. Try 101MHz BCLK as recommended, starting at 1MHz until it stops. Reset the EUFI firmware afterward. Turn off any automatic overclocking commands from Asus, as they might interfere with BCLK stability. Avoid power limits unless necessary. I’m new to Skylake non-K chips or server processors on Z170, but the CPU could still be unsuitable for BCLK overclocking as previously mentioned.

I attempted to push it to 1 MHz, but it didn’t succeed. The CPU kept showing 99.7–99.9 MHz BLCK.
