Interesting things i've learned about ryzen

[mockedarche]

I have the r7 1700 and the b350 pro4 some of this might be because of this particular set up. First Cpu usage is always extremely low when watching youtube videos and I don't been its a super strong cpu but it always seems to pass it off onto the gpu or not show how hard its working. As this thread continues to go on ill post pictures and stuff but as of right now its just something I've noticed. Cpu usage doesn't like to go higher than 60% in Linux I'm really not sure about this one but nothing seemed to use the cpu it seemed to rather want to take longer while using less. THE BIGGEST THING I'VE LEARNED IS that if I set my cpu to 3.x25 it will always turn on power steps and allow itself to turn down to 1.4 ghz so I can't have any overclock that ends in 3.x25 (NOTE I haven't tried 3.x50 or 3.x 75) there isn't an option just went from 3.4ghz to 3.425ghz and now its jumping around. Anyone else with a ryzen process feel free to post anything i'd love to learn more about my cpu.

1) Do you have any power saving options still enabled in the bios and 2) are you looking at single core utilization or the whole CPU utilization?

It's pretty normal that videos get encoded on the GPU rather than the CPU.

 

Are you mainly using linux? Does the CPU usage go past 60% during benchmark? I'm not a really linux-user myself but I'm pretty sure that ryzen needs on of the latest kernels in order to run smoothly.

 

How did you do your overclock? Can you post your settings? As far as I know the ryzen's own energy-saving-profiles get disabled once you dial in an overclock. On Windows you can allow downclock by adjusting the energy settings.

@tjcaterThat's the part that's confusing one I simply don't see ANY thing for power options. Two it would be weird for it to only trigger at 3.x25.

@crosstigerYes it is but on my familys computer there is an i5 and it in chrome uses the cpu to a much higher ( Comparably) extent especially in chrome and firefox were its less optimized compared to edge or something that is really optimized. I jumped off the Linux train got bored of it I was on 4.10 kernel xfces task manager didn't show the ghz it was at so I don't know but I had it at 3.5ghz so it wouldn't have mattered. 3.425ghz at 1.08750v (its an asrock board so that's literally all that I can change there isn't a pstate change or power settings anywhere) It's just odd as heck that its perfectly stuck at 3.4ghz but then anything that's not a solid 100mhz turns it on.

I would also like to note that this board and cpu combo are weird if I set it to 1.05v and 3.225ghz it COMPLETELY ignores my voltage and will even spike to 1.3v infact I'm going to test to make sure it wont do it with this overclock.

Edit - yeah its not changing the voltage higher than I set

The 15.5 multiplier plagues ASRock AM4 boards, even Taichi.

TBH, i wouldnt push the R7 far on the mobo you got, maximally within the CPU cooling limits of wraith spire.

I have a lot of stability issues with these as well on my 1600 actually postponed the rest of my building log because of it...

@dave_kI haven't heard of this care to explain??? I have gone to 3.7ghz just fine and to be honest this cpu is a little too beastly for anything i'd do so that or 3.8 with a new cooler would be enough. Still extremely interested I have had some issues with this board one of the sata ports casues weird stutters and well half my ram slots seem dead

The VRMs arent strong enough to handle R7 with reasonable temps without a proper airflow (120mm speedy fan over the VRM)

Also, there were some reports if you increase core ratio over 38 it will lock into 15.5

@dave_khttp://www.asrock.com/mb/AMD/AB350 Pro4/ this board? also I have a fan that's actually kind of blowing air over the vrms that being said the difference between 3.7ghz and that maybe 3.9ghz I could get doesn't bother me very much.

I think the main thing that would bug me is if I truly do keep this mobo for zen 2

It depends on voltage. I would stay within the Wraith Spire limit, especially if u want to keep the mobo.

@dave_kWhere did you hear some of this I haven't heard anything (my ear hasn't been tuned to it though)

The VRMs succ for 8 core

That isn't really surprising. On the family computer the i5 probably uses its integrated gpu cores (igpu) to render the video. I think Taskmanager shows the igpu load as generic cpu load. Using something like MSI Afterburner will show you a clearer picture of the overall usage of each core and igpu.
