Rayzen 1800X speed problem

[ysfm17]

Sorry for the long post just wanted to describe the problem with all details .

Recently the CPU " all cores " always stuck with 3.70 GHZ, the Bios settings all are auto, and I tried manually to change the CPU speed 2.20 GHZ, 3.30 GHZ, 4.00 GHZ to see what will happen.

The speed can go up, the 4.00 GHZ was done with no problems, but it wont go below 3.70 GHZ. Auto Or manually , even if the bios shows for example the speed 3.30 GHZ, when I check AMD Master, HWiNFO64 and CPUID CPU-Z, all shows that the speed " all Cores " 3.70 GHZ.

Using Gigabyte EasyTune I can select the Default setting which set the speed 3.60 GHZ " all cores " but when I reset the computer the speed again goes to 3.70 GHZ.

I also noticed that sometimes if I reset the Computer it will shutdown but will not start up, there is power but it wont start. screen, Keyboard and mouse all are black, so I have to shut down manually and start it up to work. This happen sometimes also when exiting the Bios.

When shutdown it will start up with no problems, but sometimes only the screen stays black. I have to unplug & plug the cable, if this wont work, I use the keyboard to restart to shutdown the computer and start again.

other than that there are no issues using the computer when working or playing.

The motherboard shows code " 33 " , so what does this mean?

Motherboard : gigabyte x370 gaming k7
CPU: Ryzen 1800X
GPU: Gigabyte Radeon RX460 WINDFORCE OC 4G
RAM: G.Skill Trident Z 32 GB

Cold boot issue common on Ryzen. The reset button will sort this (depending on computer case as some do not have one).

I think this is being addressed via bios updates in the future.

Do you use the latest K7 bios? What are your temps? Reset your settings before and after BIOS update everything and leave all in default. Do not load already saved profiles when you OC and you have changed BIOS. Start fresh.

Then lets us know how many cores boost and their speeds. (just use HWINFO and a run CPUZ to see that)

I had this issue with the CH6 only when I was setting LLC Level 2. When everything was Auto, 7 out of the 8 cores were boosting to 4.1Ghz with bios 1701.
Other bios versions clocked less cores. (9920 and before just 2).

Didn't have that sort of boot issue on my K7 using the F4 BIOS. The latest BIOs goes further and fixes more things. Unfortunately my board is still in RMA so haven't had a chance to test the new BIOS .

As for the speed issue, are you using the Ryzen power plan? I noticed when I applied that all the cores were at minimum stuck on the all core boost speed. Go to the advanced power settings, go to processor power management, and in the minimum processor state, drop it down to 5% or so (which is what the balanced plan is at). This will allow the CPU to drop to proper idle speeds.

Is that 4 x 8GB memory or 2 x 16GB?
