Screenshot Shows 256GB of RAM in a Threadripper System

While AMD's Threadripper platform technically supports 256GB of RAM spread across 8 slots, there are some practical issues that make building such a system difficult. Most TR4 motherboards officially support 128GB of DDR4, and unregistered 32GB DIMMs aren't widely available yet. But ComputerBase.de found a screenshot of a Threadripper system that appears to be running 256GB of consumer-grade RAM. The system in question seems to use SL Link J4BGUS2G8QHBC memory modules, and ComputerBase.de notes that they have twice the number of memory chips a typical 16GB stick has. But the ASUS ROG Zenith Extreme motherboard apparently has no issue running the high capacity sticks. The sticks are running at a relatively modest 2666Mhz with CL20 timings, but that's supposedly faster that what Threadripper is rated for at such high capacities anyway. While the 32GB sticks Samsung listed last year are still nowhere to be seen, these sticks apparently use Samsung memory ICs.
