[Guide] Lenovo Z50-70/Z40-70/G50-70/G40-70 using Clover UEFI

Wonderful, when I get home I will try it!

So, I tried your latest OC folder, and HDMI audio output does not work, neither the internal speakers of the laptop and the GPU memory increased from 1536 MB to 2048 MB. The sound worked with your Clover EFI though.

That first one has a voodoohda kext. Try it instead of AppleALC

@tatomi92 i make for you OC with voodoo (I personally prefer AppleALC because of the higher output volume)

                <key>framebuffer-unifiedmem</key>
                <data>AAAAgA==</data>

this increases the video memory to 2GB

Okay, so I tried it and it just hangs at the end of the Apple logo loading screen. :/

You're right. It was the same with me. The problem was in the configuration - which was for AppleALC. Also, every time the entire OC is changed, NVRAM should be deleted - this is what you have to do when boot menu show.

Now i tested.

As seen above OC is 0.5.7 - built from source.

I'm still not sure when it all joy together if there is a conflict in the OC.

He can do that, too. If he wants. Let him experiment alone.

I don't like VoodooHDA- due to the output volume reduced by 10% - I also prefer CodecCommander how it works.


By the way, my WiFi card is DW1820A

have no adjustment

<key>pci-aspm-default</key>
<integer>0</integer>

I have extra BIOS menu unlocked - and I changed ASPM to L0s for PCI Express Root Port 4

When the WiFi card DW1820A is set up like this when the PC goes to sleep mode - the WiFi card shuts down with the Bluetooth. And then it turns on again when I exit sleep mode. It works almost like a true hibernation.
There is also a bug in sleep mode with a DVD drive with Clover but that it has been resolved in OC.

There is a fix for the VoidooHDA there is a boost level in the plist. I set mine to 3 instead of one so I can hear the volume on the tiny laptop speakers. The key is you need an older Release of Voodoo the latest doesn’t boost even after setting it to 3. Search the Lenovo M93p Tiny thread I have a copy of it in the EFI downloads.

Okay, this one is works for me but this case no HDMI output, actually it is showing but grayed out.
