I found a rather advanced BIOS implementation when I booted up the XMG NEO 17. A lot of the features you would find in an enthusiast ATX motherboard as present here, including things like voltage adjustments and clock speed changes. Part of the available options are hidden at first boot, but a few clicks once in your OS can open them right up for you, and enable memory speed and timing changes. I'm not exactly sure why its this way, but it is what it is.
There is more to a BIOS than simply settings you can change; a big part of a consumer-facing BIOS with such options is how robust the BIOS is at recovering from settings that simply do not work. I did test this a lot with the memory setting changes, and there were several times that my settings caused the XMG NEO 17 to not boot; and each and every time the NEO 17 recovered itself and booted with default settings. I can't stress enough how nice this is to see in a laptop, and it truly leaves me excited about the NEO 17, as suddenly I have a new platform to test and play with SODIMMs.
The BIOS does also feature undervolting; a common feature that many users have asked for or attempt on their own, in order to help deal with temperatures or fan noise, and to further optimize system performance. There are several user-adjustable voltages that can be adjusted along with options for CPU multiplier adjustments, in case you'd prefer a bit less performance but far less temperature. Which ever way you'd like to run the NEO 17, its BIOS is ready and waiting for you. I have spent a lot of time in this BIOS, and am very pleased with what I found.
