Increase the size of your TX ring, meaning the number of TX descriptors. You said this is a quad port card, what size PCI E slot are you in? On some motherboards slot connectors might suggest its of a certain size but its not really wired fully. If you are not in a x8 lane slot move it to one. What about system tuning? Some ideas, let me know how it goes.
