Re: Ideapad 330 Ryzen 5 2500u underperforming

Ok thanks I understand. Now I'm waiting for an official (lenovo) or an unofficial solution for the bios update of my 330 15 ARR, I follow very often this post on reddit :

Finally got my 330-15ARR work like it should. 300+ FPS in minecraft underground. 160+ above.

At the same scene (im using same MultiMC instance) sh!tdows (W10) puts twice as less FPS. (~162 cave/70 above)

Modded (stoneblock) isn't even playable on W10 with 1 (ONE) FPS and doesnt even load most of the time.

In linux it never falls lower than 70+ FPS

 

Current setup: {FPS in glxgears with vblank 0}

I know that glxgears is not a valid benchmark. I just put it for reference.
  • Got Xubuntu 18.04.1
  • Modified EFI grub cfg to boot (nomodeset)
  • booted live {1-2k}
  • Installed [using internet on usb stick with some MT7601U]
  • Booted changing to nomodeset+idle=nomwait in grub preload {1-2k}
  • updated
  • Installed lastest kernel [4.19.6 atm]
  • Modified EFI grub cfg of installed os to boot (idle=nomwait)
  • reboot {6-7k}
  • Installed DKMS module for wifi drivers
  • reboot {6-7k}
  • Added oibaf's ppa and updated
  • reboot {9-10k}
  • (at this moment system experienced some inconsistent bootup)
  • updated firmware bins for raven ridge (and whole lotta of amdgpu's fw)
  • reboot

using system now, boots every time {9-10k}

Now I'm going to compile kernel to make touchpad work 

No way, im too lazy. And it should be presumably fixed in next couple of releases anyway.

So, poor performance seems to be a driver problem after all.

Awesome! My post about performance in xubuntu with mainline kernel and setup steps just got deleted. Good job lenovo!

 

In summary I can say this:

I am benchmarking my 330-15ARR using minecraft (MultiMC 062) due to java's multiplatform nature.

I am using same instance of Vanilla 1.13.2 And 1.0.28 stoneblock

Ram allocation and settings are persistent across platforms.

So far I got this results: (FPS in cave/FPS above ground AVG/Stoneblock FPS)

  • Windows 10 Lenovo-Bloatware edition 50/25/NONE
  • Windows 10 clean 1809 from ms site 90/40/NONE
  • Windows 10 clean with forced Adrnalin 18.10.1 160/75/1(one)
  • Xubuntu with Oibaf's mesa PPA 310/160/75+

This looks like all the problems lays in POOR driver support both from lenovo and AMD under proprietary-joke-of-an-os.

PS: For me it is just what I wanted from this laptop to replace my dead vostro (i5+740m). Won't even bother booting w10 again.

Hmm.. Looks like this guy just found the way to disable STAPM:

Very promising indeed.

There is no custom bios available for Lenovo Ideapad 330-15arr. There is throttling in basic tasks such as browsing and even unlocking the screen is hell slow after 10-12 minutes of use. Very bad laptop returning now. My previous hp laptop with Intel HD works fine with such tasks.

 

Do not talk about gaming, gaming is really not the thing for lenovo. I know Vega 8 is very good it can run almost all AAA titles but lenovo is worst. Amd is good, I have desktop of amd 2200g with Vega 8 its graphics performance is far greater than lenovo laptop. I only get 20% of score on my lenovo laptop compared to my desktop with same integrated graphics chip.

So I fixed this problem for myself when u/MinecraftAddict131 on reddit pointed where we need to change that values. Now my Lenovo 330-15ARR works, like it supposed to work. 30W STAPM Limit
