Being stuck at home, due to the current situation(...), I kept trying to fix the problems.
The power supply was changed to PowerBird 1300W and I disassembled the computer and now its laying in the table with only one card assembled (RAID controller), I'm using the board graphic card with two monitors and it work pretty good. I keep having the stopping problem during boot, the green LED keep lighting (meaning its in boot state and that's it) and nothing else happen. After many On/Off the systems start working again. any one ever had this problem?
Currently my system set to multiplayer = 49, VCore = automatic and LLC=3. I can run the IntelBurnTestV2 in reaching acceptable temperature (70)
I'm using CPUID HWMonitor for reading the CPU measurements .
I'm not sure all the testing/loading application are working correctly, I'm running the system with AVX ratio of 2 (I'm going to use this computer for also video encoding). When running HandBreak converting video (H265 12bit) the clock was stable in 4.7GHz, VCore about 1.4V, the temperature around 70 and the system power was 280W. The frequency dropping didn't appeared.
Using IntelBurnTestV2 show non-continues measurement on the CPUID HWMonitor, at first the clock is in its highest setting with temperature about 70 degrees and voltage nearly 1.4V but after a few seconds its start declining.
The clock drop to 3.8GHz and the temperature drop to 50. Is it thermal throttling? How to stop it? after all I don't mind 70 degrees on the CPU.
Running the FurMark CPU burner seems it stress the system to the maximum. The clock was stable in 4.9GHz, VCore about 1.4V, the temperature was around 80 and the system power was 320W. The frequency dropping appeared after a few minutes but it seems affecting different cores, some cores just popped down momentarily to a lower frequency but than returned back to normal speed and other cores lower theirs frequency.
-Is there a way to control VCore better? currently, on automatic every thing work fine but VCore reach 1.5V under heavy load and cause a lot of heat.
-What to do next? I'm running out of ideas how to stabilize the system with lower voltage.
-Is the testing application are really important in the real world? I try running DIVX Converter (without HW acceleration) and it reach 100% CPU for more than an hour and the temperature was less than 60 at 4.9GHz, with the same settings the testing application fails. This real world application is what I'm interested, I'll be happy if I could trust the system run flawlessly all the time.
-What is the name of the parameter controlling the clock multiplier according to the load? I used to work with 1.2GHz upon low load and pop up to 4.5 in full load, I cant remember where it was set...
