Thermal Throttling with low temps on 5930k X99

[SplendidSPL]

If been having a problem where my 5930k is stuck at 1.2GHZ, this is at 35c-45c across the cores.
MSI/Intel Extreme Tuning is telling me that I'm thermal throttling. I downloaded ThrottleStop and was getting these as the limit reasons:
BD PROCHOT
MAX TURBO
CORE P1
I honestly don't know what these mean.

I have tried disabling cores, turning off turbo boost and speedstep. I've tried manually upping the voltage and ratio which are stuck at .8 and 12 respectfully.
The problem is not visible in the bios where it shows it clocked at the full 3.5ghz it's only seen once booted into the OS.
It is persistent across Windows 7 and 10, also across bios updates a20 and a60
I've taken the cooler off cleaned it reapplied thermal paste and still no luck with the issue.
The warning light on the motherboard isn't even on.


Specs :
CPU - i7-5930k
MOBO - MSI X99A Xpower AC eatx --- a20 bios and a60 bios all at default
Cooler - Noctua nh-d15
RAM - 32GB DDR4
VGA - Gigabyte G1 GTX 980ti X2 in SLI
OS - Windows 7 Ult 64bit and Windows 10 Pro 64bit

You haven't hit the physically switch on your motherboard labelled "slow mode", have you? It's intended use is for extreme overclocking and allowing you to boot in at low clock speeds in the event of an error. EVGA have something similar labelled "MCU".

Take a look on your board, there should be a physical switch (alongside OC Genie and CeaseFire switches). I'd load optimized defaults in your BIOS before you do that too.

The LED indicating that SLOW BOOT is on, is on. However it is in the default off switched position. I originally had the OC at about 4.6ghz.
Can seem to turn it off...

I'm not sure what exactly can trigger it, but your problem doesn't appear to be unique.

Probably a stupid question, but have you toggled it on then off to see if whether that changes anything?

Looks like there's reports of the issue with a few different MSI boards............... You may have to take it up with them directly.

I'll see if anybody else has heard of this issue and potential fixes.

The switch is stuck. This may sound a little crazy but I stuck a ball of electrical tape holding the switch down. And it's fixed!
So... I'm guessing the switch itself is bad? I wonder if there is a way to disable slow boot in bios? Stupid board, paid 300 for it and it still fails in the stupidest ways.

Thank you for your help I hadn't thought of checking to see if it had stuck on... I miss the obvious stuff.

Like I said, you've had the same issue countless others have with some of the X99 MSI boards - no idea if it can be disabled in the BIOs, although I suspect not (as that would defeat it's intended purpose entirely). Glad you got it fixe.d
