yeah. not only it heats up a lot, but DDR4 also has to be retrained each time the temperature changes by more than 20°C or so, which causes a large amount of issues, especially on embedded systems

this disease runs deep and not just in consumer hardware. broadcom has carrier-grade switches called Trident, Tomahawk and Maverick, and, ugh

Branding is ridiculous.
The best part is that all of these RAM brands are nearly-identical reference PCB designs built around ICs from one of about three companies. About the only difference is whether there's a heatsink, and what color they anodized it if so.

what's worse is that DDR4 training code is so much of a secret that even Intel could only get it into coreboot as a blob, even when every other part of the firmware is OSS
on Tegra, this blob runs on the main Linux as a normal part of the kernel, which is extra hilarious

Holy crap. I bumped into this a few months ago and had no idea the rabbit hole was this deep.
