1950x questions

[samlalon]

Hi everyone,

 

I recently bought a 1950x along with a MSI x399 pro carbon ac and a 512Gb Samsung 960 Pro. After testing and making sure it was stable, I tried a light OC. Now it is 3.7Ghz @ 1.25v and it is completely stable.

 

These are my questions:

 

Percentage of CPU usage: It doesn't matter if the CPU is OC or stock, but I never see the percentage below 15%, even at idle. In fact, according to the Windows Task manager, there are always 4 cores at 100% usage at all times. The rest of the cores are 1-3% (I insist, this happens at idle). Thus windows calculates the average use among all cores and says "15%" (at idle). Is this normal?

 

Voltages: Before OC, with everything at stock, I could see the CPU voltages fluctuating from... let's say 1.20 to 1.40. Moving very fast, and most of the time closer to 1.40 than 1.20. I once read that AMD recommended (when doing OC) no more than 1.35v to be safe. Is this high fluctuation normal? Now I have the CPU with this light OC I mentioned before, and the voltage is manually set at 1.25v which I supposed it was safe, wasn't it?

 

Temperatures: I thing this issue is due to my case and fans config, but I would like to know whether it is normal. My case is a Fractal Design Define R5 and the CPU fan is a Noctua NH-U14S TR4-SP3. I also have 2 fans pushing air into the case (2x Noctua NF-P14S Redux 1200) and 2 fans pulling it out (the ones that came with the case). The noise level is awesome, it is really low. And this is the reason why CPU temperature is always about 47º-50º at idle. When I play games (Battlefield 1) temperature keeps around 65º. I don't play much, I didn't buy the computer for that. I am normally editing photos, and temps are around 55º.

OK, these temperatures are high because I set the fans at very low revs. However when I set all fans at maximum revs, I hardly reach 38º at idle. Never less. However in this situation, the noise level is... terrible. My question is: is it safe for the CPU to be always around 48-50º?

Percentage of CPU usage is 100% not normal. You're right in how Windows calculates it, but there's zero reason for 4 cores to be pegged at idle.

 

your load temps of 65C are pretty normal, but idle ones aren't. That implies that the load you're seeing at idle is accurate, and something actually is pegging your cpu at idle.

 

What process is actually causing the % load?

Check what process in task manager is making your CPU cores ramp up

You don't want to go over 1.35-1.375V for daily use with Ryzen, really though I wouldn't bother OCing at all most likely. Your CPU is going to be fine at that temperature.

You bought a 1950X for photo editing? Does it run like batch operations really quickly?

What programs are you using to overclock? What are you using to monitor CPU temperatures and voltages? Do you have Ryzen Master running?
