Please provide a link to full specs for both memory sticks.
Try each stick alone in each dimm socket and report the results.
Please inspect the memory sticks, graphics card, and their respective mobo slots and report if there are any burn marks or if you can still smell it on one part. Then inspect the remainder of the mobo for any signs of electrical issues - such as burn marks or bulging capacitors.
When you smell something when working with parts at start up is a sign of failure. So I would start looking for burn marks and any burnt out components such as mosfets. Check the card its self first the if that looks ok start looking around the pci-e slot then move on up to the cpu and ram power stages near the socket as well dim slots. If it is on the board the board is toast you will have no choice but to buy a new one. You can buy another copy and do a swap with out having to wipe the hard drive or install any new drivers except for you new card.
Those who only read one line never get any thing fixed.
