[SOLVED] Maya 2018, slow rendering on Ryzen 5 1600

[Zvonkoo]

I am rendering a project in Maya 2018 student with Arnold(renderer, uses cpu not gpu), making frames in 1280x720 .jpeg and its going really slow, CPU utilization is not going over 43%, and pc freezes every few seconds, im frustrated, while on my friends i3-8100 it uses 100% of cpu and renders faster than me.

My specs:
Ryzen 5 1600
DDR4 G.SKILL TRIDENT Z RGB 2X8GB @ 3000 MHZ
MSI B350M GAMING PRO
ASUS HD 7950 3GB
240 GB SSD, 550/500

and my friends PC:
i3-8100
8GB 2133MHz DDR4
Some cheap MB
ASUS GTX 1050Ti 4GB
240GB SSD

Drivers up to date. Any help?

1. is your ram running @ 3000?
2. what cpu speed is it running?
3. try to activate opencl in rendering settings.

If it never goes above ~43% then it probably only sees one module/ccx in your place I would search in the settings if you can enable it to see both ccx search for numa settings,also you should try the maya forum to get some people that actually know the software.

Oh my RAM is not running @3000MHz, when i assembled my PC it was running @3000, but now, year later its @2133MHz, what should i do?

That could be the reason. I guess you have reset bios somehow? Just try XMP in bios. Same cpu/mb here.

I did, it set the RAM to 2933MHz, still using only 43%, flat 43% line...

It's a good thing you supplied that image. IMO, your CPU is overheating, or the PSU or motherboard is not supplying the CPU enough power.

CPU is at 43%, but it is also at 1.38Ghz. That appears to he a CPU throttling situation.

You need to figure out why it is dropping to idle.

Temps should have been the first question for any throttling issue.

this seems to be be bios bug (locked p2 state), update your bios

I provide you all this image with temps.

My PSU has effective power of 500W. My GPU is quite old, its AMD Radeon HD 7950 3GB with TDP of up to 225W, drivers up to date. My CPU has max TDP of 60W. I have 2 HDDs @7200RPM, one 240GB SSD and 16GB(2X8) DDR4 RAM. And my CPU is watercooled. I have changed thermal paste 6 months ago, pump is working fine.

Those are temps after a few frames, and i use Arnold(renderer) that uses CPU to render.
Those gaps are when render of frame ends and starts another frame.

Only thing that i didn't try is BIOS update, i will do it tomorrow morning since its really late here in Europe.

I have updated bios and i did activate XMP profile 2, now its using 100% of CPU, thank you all!!!!

Good eye kerberos, glad the drivers toko care of your problem Zvonkoo. I was also thinking Windows power plan settings as another possible solution. Power plans can throttle the CPU before upping the fan speeds if it is set to passive.

That's not exactly an overheating situation, but cpu gets throttled to control temp instead of using the fan more actively.
