Cool. How many pins on the connector? 560? vs 288 on a DDR5 DIMM? I can't find any pictures/vids of the connector. Would love to see how the stacked config looks/connects.

  I took a look at the standard, and it's a 7x44 connector for each channel of memory. That gives 308 connection points, which is slightly more than 288 on a DIMM. Dual-channel modules (as shown in the article) simply double the number of pins to a 14x44 connector (616 pins)

Thanks, I thought it's talking about data compression. So clueless to not understand what the article talks about, as I was expecting things like hardware accelerated RAM.

  CPU packages are starting to have issues with too much or too little pressure from the heatsink mounting to cause pin contact issues too. AMD Threadripper has a $30 torque wrench that is suggested to secure the package.

  LPDDR module support is SO great, I've never expected this to come. Great work by industries.
