BCLK Fluctuating on Asus X99 Deluxe II
BCLK Fluctuating on Asus X99 Deluxe II
Hello everyone! My current setup (Asus X99 Deluxe II / Intel 6850K) has been overclocked to 4.4 ghz @ 1.325 volts. The multiplier is at 44 and the BCLK is at 100. I keep it running nonstop for about 24 hours, but the cooling system (Kraken X61) keeps the temperatures under control, never exceeding 61°C on the hottest core, which is usually around 53°C. Over the past three weeks, the machine has run continuously without any interruptions, though the clock speed varies between 3500 and 4600 MHz. The multiplier remains stable, but the BCLK isn’t consistently at 100 as it should be in the BIOS settings. It swings between 97.xx and 102.xx. I’m hoping to keep it steady around 4400 MHz. Anyone have any ideas on what might be causing this, or how to bring it back to a more consistent speed? Thanks ahead for your support!
Turn off Intel speed stepping in your motherboard's BIOS. If it's new, you might need to choose advanced bios settings to disable it. This feature helps save power when your system is idle. In Windows 10 and later, go to power plan settings for the board, pick High performance, apply and click OK. Restart and check if Bclk fluctuations stop. The CPU should run at a steady 4.4 GHz.
