Asus NitroPath is interesting. they're using a new type of contact in their DIMM slots which loops downward, eliminating the small stubs at the top of the contacts, reducing the antenna effect when slots aren't populated, and keeping the contacts more contained within the shielded slot connectors.
they've published eye diagrams to show the practical impact on signal integrity. pretty neat!
@gsuberland I'm honestly surprised that wasn't common practice already.
@azonenberg it'd be cool if they'd have published S-params to go with the eye diagrams, so we could get a feel for how this behaves in other scenarios too.
@gsuberland Assuming this isn't an Asus internal connector... Wonder if they worked with Samtec or somebody to design and manufacture it?
@azonenberg I would be amazed if they were doing this fully in-house. definitely seems like they'd be contracting it out to Samtec, TE, or Amphenol.
They didn't do it them self, they have a one year exclusivity deal. They do also provide a chart for one other condition.
@ekg @azonenberg yeah that's the video where I spotted this feature (mentioned in the alt text)
@gsuberland @azonenberg I am pretty sure he mentioned the manufacturer. I can't find your source in your alt text, or the rest of your post.
@ekg @azonenberg end of the alt in the second image
must've missed him mentioning which vendor they used for connectors. I'll have to scan through.
@gsuberland doesn't show up in my client. And I can't get the Web interface in Firefox to show the alt text at all.
Don't mean to imply that you have done anything wrong, but I can't see what you are seeing. Probably down to technical limitations on my side.
@ekg how bizarre
