A simple, quad channel DDR3 based clock for the lab.
Big wooden, steel-frame table with wheels. On top of it, an old ASRock Z97 motherboard with an i7-4790K. Four old GTX 1080 cards side by side in the slots, held by a wire. A dark mechanical keyboard, power supply, and two more graphics cards lying around the motherboard. A tiny mobile display shows the time – from about 24 hours ago, because I spent the rest of the time typing alt text on my iPhone without glasses.

0.5mm pitch is okay for a milled PCB, but together with the large thermal pad, soldering is going to be quite challenging without a stencil. Örgs. Maybe I will mill a slot and solder it from the bottom then lol.

Apparently, it was a bad idea to put a dot in the Apple support forum’s username when it was still allowed.
Screenshot of a „403 Forbidden - Apple“ page when I try to access the support forum. My user name is „.DS_Store“. Only used it one or two times, so no loss, but it‘s still half there and still not usable.
