Lenovo Yoga 530 14ARR Drivers- and BIOS issues

2019-01-04, 12:54 PM

As a game developer I wanted to point out a couple of quite big problems with the Lenovo 530 Ryzen Mobile laptops, I hope this can gain some traction and eventually reach the developers of drivers- and BIOS'es at Lenovo.

 

 BIOS

            

  • Unable to allocate VRAM. 256MB up to 2GB should be available in the BIOS. This is a really big issue since 256MB renders some applications useless. I can't activate full hardware acceleration in Adobe Photoshop CC. Black Magic Da Vinci Resolved won't start due to limited VRAM. Texture streaming is having issues in Unreal Engine 4. I know that the GPU can dynamically allocate more VRAM if needed, however a lot of applications need 512MB (or more) of dedicated VRAM in order to run, please increase this, or preferably let us to choose how much we want to dedicate to the GPU.

 

  Radeon Drivers

                                   

  • Can't  add custom resolutions to internal screen (although it works on external screens) - I was able to do so with registry hacks, without any issues. With this being said, it should be supported by the Software itself.
  • AMD Hardware Codec doesn't work for encoding videos, making it hard to stream or encode videos over the GPU
  • Freesync doesn't work properly - I have a freesync monitor at home. A MSI Optix 27CQ. The Yoga 530 can't provide freesync to it although it is being promoted on AMDs site. And then there is a strange thing where the monitor can only use 120Hz in 1080p, but not 1440p. This could be a bandwidth issue. The computer can't however do 900p120Hz or 720p120Hz, although the monitor supports both these resolutions and refreshrates over hdmi.... my other computers can provide these resolutions and refreshrates, even with hdmi older graphics cards with 1.4b standard.

 

Power Management

                                        

  • Low 3D performance due to bad power management - Since the system is 15W it does suffer from being too powerful for what the cooling can provide, in terms of gaming, it is almost always preferable to run the CPU at a locked 1600MHz, giving the GPU more room to breath. You can gain up to 30% more performance in GPU heavy scenarios, However, this needs to be done by creating power profiles in the old "Power Settings" in Windows. This should be built into the power mangement itself (example, If a task requires CPU but little GPU run the CPU at 3200Mhz, and application using 600+MHz GPU, should decrease CPU to 1600MHz by default) or it could also be implemented as a "Gaming Mode" toggle provided by Lenovo Vantage.

 

For those of you who feel that you have the same kind of problems, please click on the "I have this problem as well" and give it some kodus. I really think that this needs to be adressed in future driver- and BIOS revisions.

Agree! I'm using Flex 6 with ryzen 2700u, which is the US version of Yoga 530. It will be really hepful if we can increase the vram size in bios. 256MB vram is too little to be usable. Even powerpoint will get freeze when I'm trying to playback some video inserted (which can be played smoothly on even an 2012 imac).

 

And of course, if the tdp can be increase to 20 or 25 when the laptop is plugged in.

Wholly agree, I also need these issues fixed. If it weren't for these issues this laptop would be perfect for me. I've already recommended this laptop to a friend and he bought it and faced the same issue with 256mb vram on adobe photoshop. Other applications issues will follow suite.

 

We need more options from insyde bios unlocked, VRAM ammount; TDP and disabling STAPM completely when using performance mode. 25W TDP while on AC adapter is really not unreasonable for it's active cooler + chassis passive cooling.

 

I don't face as many performance issues as I had at purchase with the newest bios, but now I have trouble with very slowed going to sleep after closing lid and waking up/startup time after reset. (8PCN50WW). 

 

Thank you for initiating this thread, I will be following closely.

I hope we have improvements to this issues soon.

I suggest you give this a try, I had some success in reducing throttling with this:

Agree with this. 256 Mb VRam was enough around 2009, but these days minimum the 1 Gb Vram start editing in PS.

 

I chosen this Yoga 530 14ARR with 16Gb of ram to I can share 2 Gb of ram or the Vega.

Is there now a way to inrease the vram? Or does somebody have another solution for this. Im pretty sure that when i bougt my laptop i had 1gb vram. But now i only have 256mb and i dont know why it set down. An answer would be really nice from you guys.

The issue remains... The latest BIOS introduced power management bugs (fortunately enough a support agent gave me an option to downgrade) To me, I basically went around the VRAM problem by using newer software. 256MB itself isn't a problem in itself since the GPU "should" dynamically allocate more DDR4 whenever needed. But yeah, that's in a perfect world... however, it usually falls short at the software developer side of things. Like Unreal Engine only looks at dedicated VRAM, and not "total available VRAM", same goes for older Photoshop- and Premiere- versions. I used CS6.... nowadays I use Krita and Da Vinci Resolve to satisfy those needs.

 

The support agent speculated that perhaps it could be impossible to enable VRAM allocation in BIOS since the setting might be on a hardware configuration level... Although it is just speculation, she could be right.... It seems like the VRAM limit has been increased in newer 3000-series ryzen yoga machines. So there's a possibility that we're stuck with this VRAM-issue on the 2000-series ryzen yoga machines.

 

My thoughts on the machine so far

+ Powerful ultrabook APU

+ Form factor is great - 14 inch + thin and light

+ Good construction, Keyboard, and chassi doesn't have much flex.

+ Small and light power supply.

+ Pen support

+ Hinges, mine are still good after 1½ year of use. and perfect for drawing.

- Abysmal battery life for the form factor (I generally get 3-3.5 hours use when unplugged)

- Inadequate cooling.... a dual fan solution would enable full performance far longer

- Screen is somewhat dim, hard to use in brightly lit environments.

- No power delivery over USB-C.

- Bug 1: HDMI 1.4b, generates a lot of incompatibility with 120Hz+ and 1440p+ monitors.

- Bug 2: Low dedicated VRAM, causes unnecessary software incompatibility

 

If the minuses were fixed it would be an AMAZING laptop.
