Possible build for Precision 3551? #6

Recently I obtained Precision 3551 and started my own Hackintosh build. Then I found a serious problem related to the iGPU - UHD 630. For some reason, there seemed no limit for its frequency. As a consequence, graphics card can even boost to 6 GHz under high usage, according to Intel Power Gadget.

And all of a sudden I discovered that Latitude 5411/5511 share the same BIOS firmware with Precision 3551. I've looked through specs of each and indeed they do share a lot of hardware. While I tried to reproduce your successful result, however, I can't load your EFI. It failed to boot.

So I'm somewhat curious about the iGPU performance on your build. Likewise, is it possible to employ your build on Precision 3551?

Sorry for my late reply. Not working on my build recently. So... Sorry.

I forgot to take a photo when it couldn't boot. I'll try that out soon. But for the graphics issue I'm encountering, I still got my screenshot. Here:

To my knowledge, it's impossible for UHD 630 (more specifically 0x9bc4) to clock over 1.15 GHz. However, it can easily get to 3 or even 6 GHz, especially awake from sleep.

I have no clue on this.
