I've built a few X299 systems, now, and I thought I'd share some observations about the motherboards that are available. To my mind, the best way to break down X299 motherboards is by the way that they handle routing of PCI-e lanes. Having 44 (or with Cascade Lake-X, 48) CPU lanes is the big...

This guide is applicable, at a minimum, to the Precision 7540 with i5 or i7 processors (I haven't looked at whether the Xeon can be used). The advantage of a Precision 7540 is that it can be ordered with an AMD WX 3200 discrete GPU (very few PC laptops combine an Intel CPU with a compatible AMD...

Recently I got a Supermicro AOC-SLG3-2M2 dual M.2 card. You can use two x4 M.2 NVMe drives in this card, and it's inexpensive, but the PCI-e slot has to support bifurcation. Well, how to do this depends on your chipset. The newest ones can handle it automatically. It's not so simple on most X99...

On my S41 only the power button can cause a wake. Is there a DSDT patch or some other method I can use to cause the built-in PS/2 keyboard in my laptop to wake the system from sleep? My PS2K device does not have a _PRW method. All it has is _HID and _CID, plus a _DSM (that I added) and a _CRS...

Hey everyone, This is an issue that I think will mostly affect people with laptops, because they are sometimes single channel machines, but I'm posting here to request some assistance investigating this problem. It seems that if your RAM is only connected to the B channel of the processor's...

Update 6/6/17: this machine is on 10.12.5 now, which required the addition of Lilu and IntelGraphicsFixup. Due to the problems with Skylake and Kaby Lake integrated graphics, it's still the best current hardware, I think. That's all about to change, soon! --- Hey everyone, got a new laptop...

I've been working on a Samsung RV520, so far I followed the usual process for a Clover install of Yosemite. This is from the thread on battery DSDT patching: I'm using AppleHDA patched for ALC269, of uncertain provenance. All in all, running pretty good for a machine with a few years...

I'm getting weird audio with my new Probook 4540s. See the attached video - it sounds like it's sort of stuttering. The machine is running 10.8.5 with the supplemental update. I searched this forum and found that some other people had similar issues. Based on those threads, I tried two...
