observed this earlier, just curious image: the connector isn't flat. I think because applying pressure to all contacts at once demands a lot of force, this layout lets the middle contacts move first before the sides, reducing the peak force needed. Am I correct or is this just a myth? Edit: nvm, I tweaked some keywords in Google and the results confirmed my idea. Edit 2: kept getting truck-related answers before zzz
The issue arises because some DDR4 modules include pins of varying lengths.
Typically individuals place the module on one side initially, which helps spread the force evenly around the center.
That's correct, if the tolerance is very tight, putting one side in first could cause pins to stick in the connector gap. Inserting at an angle might help balance the connector. I’d probably need to draw some CAD sketches or use paper and pencil to calculate it. For DDR4, the pins are still relatively large, so a slight offset shouldn’t be a big issue.
