No kidding? A "Slow Mode' switch......
Any idea why in the world it's there to begin with and, why in the world is it set to this a Degault from the factory? |

You are working with a sophisticated board that has a few options/features that are unusual compared to other boards. I've seen this "issue" with other OC Formula users, and I have a different version, but it has the same option that is most likely causing the problem. Page 7 of the X99 OC Formula manual shows the mother board layout, which I have included below. Item 14 is the Slow Mode switch, which locks the CPU into its lowest speed, 1.2GHz. I believe you will find the Slow Mode switch set to On, as it normally is from the factory.  I've always wondered how the Slow Mode switch worked. You may have discovered its secret by running IXTU. Or a side affect of the switch causes Thermal Throttling to be set to 100% when it is set to On. Be sure to shutdown and shut off power to the PC before you set Slow Mode to Off. It seems you may be able to toggle that particular switch with the board powered up, but I'm not 100% sure that is true. Don't forget to reset anything you changed in the UEFI when you tried to OC, in case you entered any wild values to see if they would be applied. Once Slow Mode is Off, they will be applied. If you are still having any issues, let us know. |

Clarification I don't rely on the fans installed in/on the case to get the needed airflow over the VRM sink. All things considered, once you mount the rad things get cramped and tight up in that corner. "That corner' being where the VRM sink resides. SpotCools allow me to put airflow where it's needed w/o disturbing the flow of air the rad depends. |

And seeings you're using water cooling, can I assume you're making up for the lack of cooling airflow over the VRM sink by positioning an aftermarket 3rd party fan blowing over the VRM sink to cool it?
When water cooling I personally do not rely on case fans. Instead I here use Antec SpotCools directly over the VRM sinks. |

Going by what you describe and my experiences I'd look to see if one of the heatsinks on the MB came loose? Beginning with the one over the VRM section !
Do you feel the temp is high or low when you get near the sink covering the VRMs? How about from the backside of the board? This might be a better indicator than from the top side. --- Pics I can locate appear the sinks are screwed on from the backside. Might check that they're snug/firm/tight. |

I am not new to OCing and this is a new one for me. I am building a video editing machine for a friend.
I am using the Asrock X99 OC Formula board, with an i7-5930K. Cooling it with the Swiftech H220-X Before I have even get to over clocking I installed Intel's extreme tuning utility. When I run it thermal throttling is at 100% and the CPU clock stays at 1.2GHz no matter what I do. The core temps are all around 23-27 degrees C. I've restored the default setting in the BIOS, the BIOS is version 1.2 the most recent. I don't see any power management settings, the junction temp cut off is set to 105. The manual actually shows under Voltage Configuration a Power Saving Mode, but I don't see it in the BIOS. Changing the Vcore, CPU multiplier etc has no impact. I've tried everything I know that might cause the CPU to throttle at a low temp to get the CPU to stop thermal throttling. I am at a loss how to fix this. Any help would be greatly appreciated.
