I believe they will invoice you for the 4.0 upgrade and you will only need to top up the extra so you don’t have to cancel your order.Thanks for the update on this. I emailed support requesting to change my order to alu+pcie 4.0.
Is that the best way to go about it, or should I place a new order and request to cancel the 3.0 order?
Ultimately I may keep the 3.0 order but want to make sure I do things properly if I do switch.
