bad FPs need help

Mr.Fahrenheit
Go to solution Solved by RyzenDoctor,

It was on slow mode. On MSI motherboards it’ll boot with 800mhz, expect sub ambient temps to reach the normal range of temperatures. If the temp is deemed higher than what’s expected on liquid nitrogen it throws a throttling signal at the CPU which prevents it from going beyond 800mhz

Interesting..l wonder if your multiplier in the bios is set to 8 hence the 800mhz.

 

CPU speeds are determined by Base Clock X a factor. Most new motherboards run at a base clock of 100mhz, and the cpu is running at multiples of that.

 

your pc is starting off at 800mhz and not ramping up. You seem to have thermal headroom. I’d try resetting the bios settings on the motherboard to default and see if that’ll fix it.

 

otherwise try to manually increase the multiplier to where your CPU should be.

While Booting PC up it should say how 2 enter BIOS iw will be F8 or DEL button, just spam those while booting up.

Reboot your machine. As it is restarting it should tell you how to enter BIOS.

 

usually it’s by pressing Delete or F2.

 

Here is your motherboards manual

http://download.msi.com/archive/mnu_exe/E7977v1.0.zip

 

once inside you can do 1 of three things:

1- look at your overclocking page: ideally your core ratio should be set to Auto and the base clock should be on auto and showing 100mhz. If they’re not on auto, change them to auto

2- under Bios exit you have the option to restore defaults

3- you can update the bios from here using the file linked by @KnoT

Do take A picture with your cell phone from the overclocking bios page as it’ll be interesting to see it

Yeah there is something wrong with your OC. By looking at it you should be running at 4.3ghz on all cores (43*100) but you’re stuck at 800mhz. Just reset to defaults.

I couldn’t find where to do that. I’m sorry if this is a little frustrating

When you’re trying to quit the bios (usually F10) it’ll be on the list of things you can do.

 

another thing that I found online is this 

http://www.tomshardware.com/answers/id-3520459/7600k-stuck-800mhz.html

 

if resetting the bios doesn’t work it may be due to a sensor failing on your motherboard that is signaling the CPU to throttle.

 

try using Throttlestop from the link below

My guess is you’re experiencing a BD_Prochot issue.

 

there is a switch called “slow_1” on your motherboard. Make sure it is switched to the left “normal” position. For its location refer to your motherboard manual page 41.

 

this controls a sensor for liquid nitrogen cooling. When turned on it expects the motherboard to be cooler than ambient. If it’s not, it sends a freak out signal through something called BD_Prochot to the CPU forcing it to throttle.

 

if it’s set to normal, then the sensor being controlled by it may be malfunctioning .

Oh and if I wasn’t clear Turn off your PC first before messing with that.

Here is its location on the motherboard

I would reset the bios to default. I believe there is an X to the top right corner of the bios. 

 

Turn off off the machine, unhook cables, and take a peak at the motherboard. Take a picture of the switches at the bottom. If you can easily identify slow_1 check if it’s clicked to the left.
